Avoiding Cursor - Want Set Based Solution
Hi there!
Here is my situation:
table 'ReceiptHeader'
IDCustomerIDDateCreated
1225102/06/2002
1332102/09/2002
1444002/15/2002
table 'ReceiptDiscount'
IDDiscountIDReceiptHeaderIDAmount
111210.00
241250.00
311325.00
**a receipt can have multiple discounts**
Table 'ReceiptDetail'
ReceiptHeaderID LineItemIDTotal
121155.33
131145.33
141241.66
**for this example there is only one line item per receipt**
Without using a cursor, i would like to return a result set
like this one below using a set based solution...
ReceiptIDCustomerIDDiscountTotal
1225160.00155.33
1332125.00145.33
144400.00241.66
Thanks,

Avoiding Cursor
This query uses a cursor to fetch a parameter and pass it to another Stored proc. Is there a straightforward way to do this without using a cursor? declare @deleteunassigned int declare cur_unassigned cursor for select distinct a.cust_cont_pk from cust_cont a, cont_fold_ass b (NOLOCK) where a.cust_cont_pk != b.CUST_CONT_PK open cur_unassigned fetch next from cur_unassigned into @deleteunassigned while @@fetch_status = 0 begin exec spDeleteCustContbypk @deleteunassigned fetch next from cur_unassigned into @deleteunassigned end close cur_unassigned deallocate cur_unassigned GO declare @deleteunassigned int declare cur_unassigned cursor for SELECT DISTINCT a.cust_cont_pk FROM cust_cont a, cont_fold_ass b (NOLOCK) WHERE a.cust_cont_pk != b.CUST_CONT_PK open cur_unassigned FETCH NEXT FROM cur_unassigned INTO @deleteunassigned while @@fetch_status = 0 begin exec spDeleteCustContbypk @deleteunassigned FETCH NEXT FROM cur_unassigned INTO @deleteunassigned end close cur_unassigned deallocate cur_unassigned GO Future guru in the making.

Help In Avoiding The Use Of A Cursor
Here is a simplified example of a problem I am facing. I have 2 tables: Tasks and Employees. Tasks: (Task_ID, Task_Name, Task_Type, Task_Requirement, Employee_ID) Employees: Emp_ID, Emp_Name, Emp_Specialty, Emp_Task_Cnt, Max_Task_Cnt Requirements: Write a MS SQLServer 2000 Storeed Procedure to: 1. Update the Tasks table by assigning the task to an Employee. 2. Incrememnt the employee's Emp_Task_Cnt for each Task assigned. 3. Match the Employee to the Task by matching the Task_Requirement to the Emp_Specialty. 4. Do not exceed the employee's Max_Task_Cnt. I have a working solution to the requirements, but it involves using cursor logic. For all the obvious reasons, I wanted to avoid using a cursor (or cursor-like looping structure) but could not figure out any other way to avoid processing the Task table one record at a time because of the: "4. Do not allow an Employee's Task_Cnt to exeed the Max_Task_Cnt." Q: Is there a way to do this without using a cursor and still meet all of the requirements?

Set-based Solution
Thought I'd got my head round using a set-based approach but my brain's gone dead on this one CREATE TABLE #mytable (SWID INT , T INT , DateA DATETIME , DateB DATETIME) INSERT #mytable (swid , t , DateA , DateB) SELECT 63967 , 1 , CAST('31-Mar-2006' AS DATETIME),CAST( '01-Aug-2006'AS DATETIME) UNION ALL SELECT 63967 , 1 , CAST('31-Mar-2006' AS DATETIME),CAST( '01-Feb-2007'AS DATETIME) UNION ALL SELECT 63967 , 0 , CAST('15-Mar-2006'AS DATETIME) , CAST('01-Aug-2006'AS DATETIME) UNION ALL SELECT 63967 , 0 , CAST('15-Mar-2006'AS DATETIME) , CAST('01-Feb-2007'AS DATETIME) UNION ALL SELECT 63967 , 9999 ,CAST( '28-Feb-2006'AS DATETIME) , CAST('01-Aug-2006'AS DATETIME) UNION ALL SELECT 63967 , 9999 ,CAST( '28-Feb-2006'AS DATETIME) , CAST('01-Feb-2007'AS DATETIME) UNION ALL SELECT 63967 , 9999 , CAST('31-Jan-2006'AS DATETIME) , CAST('01-Aug-2006'AS DATETIME) UNION ALL SELECT 63967 , 9999 ,CAST( '31-Jan-2006'AS DATETIME) , CAST('01-Feb-2007'AS DATETIME) UNION ALL SELECT 10051 , 1 ,CAST('31-Mar-2006'AS DATETIME) , CAST('01-Aug-2006'AS DATETIME) UNION ALL SELECT 10051 , 1 ,CAST( '31-Mar-2006'AS DATETIME) , CAST('01-Feb-2007'AS DATETIME) UNION ALL SELECT 10051 , 0 , CAST('15-Mar-2006' AS DATETIME), CAST('01-Aug-2006'AS DATETIME) UNION ALL SELECT 10051 , 0 , CAST('15-Mar-2006'AS DATETIME) , CAST( '01-Feb-2007'AS DATETIME) UNION ALL SELECT 10051 , 9999 ,CAST( '28-Feb-2006'AS DATETIME) ,CAST( '01-Aug-2006'AS DATETIME) UNION ALL SELECT 10051 , 9999 ,CAST( '28-Feb-2006'AS DATETIME) , CAST('01-Feb-2007'AS DATETIME) UNION ALL SELECT 10051 , 9999 ,CAST( '31-Jan-2006'AS DATETIME) , CAST('01-Aug-2006'AS DATETIME) UNION ALL SELECT 10051 , 9999 ,CAST( '31-Jan-2006'AS DATETIME), CAST('01-Feb-2007'AS DATETIME) UNION ALL SELECT 10051 , 9999 , CAST('31-Dec-2005'AS DATETIME) , CAST('01-Aug-2006'AS DATETIME) UNION ALL SELECT 10051 , 9999 ,CAST( '31-Dec-2005' AS DATETIME), CAST('01-Feb-2007' AS DATETIME) UNION ALL SELECT 10051 , 9999 ,CAST('30-Nov-2005'AS DATETIME) , CAST( '01-Aug-2006' AS DATETIME) UNION ALL SELECT 10051 , 9999 ,CAST( '30-Nov-2005' AS DATETIME), CAST('01-Feb-2007' AS DATETIME) select * from #mytable order by SWID desc, DateA desc The Columns where T values are 1 and 0 are OK having already been derived. I need to UPDATE the remaining rows from the Default T Value of 9999 to Decrementing values (starting at -1) commencing at the highest remaining (ie non 9999 T Value) DateA value and working 'backwards' 'grouping' on SWID The DateB value is irrelevant for this purpose The desired output is below with derived T values SWIDTDateADateB 6396712006-03-31 00:00:00.0002006-08-01 00:00:00.000 6396712006-03-31 00:00:00.0002007-02-01 00:00:00.000 6396702006-03-15 00:00:00.0002006-08-01 00:00:00.000 6396702006-03-15 00:00:00.0002007-02-01 00:00:00.000 63967-12006-02-28 00:00:00.0002006-08-01 00:00:00.000 63967-12006-02-28 00:00:00.0002007-02-01 00:00:00.000 63967-22006-01-31 00:00:00.0002006-08-01 00:00:00.000 63967-22006-01-31 00:00:00.0002007-02-01 00:00:00.000 1005112006-03-31 00:00:00.0002006-08-01 00:00:00.000 1005112006-03-31 00:00:00.0002007-02-01 00:00:00.000 1005102006-03-15 00:00:00.0002006-08-01 00:00:00.000 1005102006-03-15 00:00:00.0002007-02-01 00:00:00.000 10051-12006-02-28 00:00:00.0002006-08-01 00:00:00.000 10051-12006-02-28 00:00:00.0002007-02-01 00:00:00.000 10051-22006-01-31 00:00:00.0002006-08-01 00:00:00.000 10051-22006-01-31 00:00:00.0002007-02-01 00:00:00.000 10051-32005-12-31 00:00:00.0002006-08-01 00:00:00.000 10051-32005-12-31 00:00:00.0002007-02-01 00:00:00.000 10051-42005-11-30 00:00:00.0002006-08-01 00:00:00.000 10051-42005-11-30 00:00:00.0002007-02-01 00:00:00.000 Thanks in advance

SET BASED Solution To This Problem?
Greetings all, Looking for a set based solution to the following SQL problem. I've got a solution that uses a while loop but I have a feeling that there is a better way to do this! I will use a simplified dataset as an example as I don't want to swamp you with too much detail about my real table structures etc... I have the following tables (plus some sample data) : insert into dbo.VehicleModel select 1, 'RT 100', NULL union all select 2, 'TGB ACKROS TEC', NULL union all select 3, 'TB 50 PREDATOR 2', NULL union all select 4, 'TGB 409 CRUISE 50', NULL union all select 5, 'ESCOR SUPER SONIC 400SL', NULL union all select 6, 'SUPER SONIC 150 XI', NULL union all select 7, 'RT X 350 SERIES', NULL union all select 8, 'TB SALON 4000', NULL create table dbo.VehicleModelNorm ( VehicleModelNormIdint ,VehicleModelNormvarchar(100) ) insert into dbo.VehicleModelNorm select 1, 'ACE' union all select 2, 'TGB ACKROS' union all select 3, 'SUPER SONIC' union all select 4, 'TB 50' union all select 5, 'RT' union all select 6, 'TGB' union all select 7, 'RT' union all select 8, 'TB SALON' What I need to do is update the VehicleModelNorm column in VehicleModel with the relevant ID from the VehicleModelNorm table. Sounds easy enough BUT here is the catch. In my vehicles table the VehicleModel are the actual vehicle model names. In my vehicleNorm table I have a more generalized name. What I want to do is look at each VehicleModel, try to find a match in the VehicleModelNorm table, if there is no match then chop off the last word and look again. For example, starting with 'RT 100 7 SERIES', I want to try to find an exact match for that in my vehicleModelNorm table. If there is no match, remove the last word and look for 'RT 100 7' then look for 'RT 100' etc... How can I do this in a set based solution? I can do this with a WHILE loop but I have a feeling it might be possible to do this with a CTE but I just can't get my head round it. Your advice would be much appreciated!

How To Write Set-based SQL Instead Of Cursor
Guys Here's the scenario create table data1 (dealid varchar(6) , datex smalldatetime , Tn INT) insert data1 (dealid , datex , Tn ) values ('12345' , '31-12-2005' , 9999) insert data1 (dealid , datex , Tn ) values ('12345' , '30-11-2005' , 9999) insert data1 (dealid , datex , Tn ) values ('12345' , '31-10-2005' , 9999) insert data1 (dealid , datex , Tn ) values ('98765' , '31-12-2005' , 2) insert data1 (dealid , datex , Tn ) values ('98765' , '30-11-2005' , 1) insert data1 (dealid , datex , Tn ) values ('98765' , '30-11-2005' , 0) select * from data1 I need to update the Tn column from the default 9999 for the 3 rows in this table where the dealid is 12345 based on the value in the datex column so the row with the 'highest ie most recent date' gets a 0. I then need to assign the value 1 to the next highest and so on until all rows (in this case 3) get incrementing integer values. It's easy with a cursor but can't get my head round doing it in a set-based way Any ideas

Cursor, Set Based Approach
I am replacing cursor logic in a SP to a setbased approach to scale better. My setbased approach seems to be better but it runs very fractionaly faster (execution time) than the cursor approach for a single run in test environment. I think resource cost wise, my set based approach should be better. Number of rows iterated thru this cursor is small (0-150). This particular SP is called over 2000 times in production everyday. Is it worth the trouble changing this if we get only marginally benefits, will my set-based approach work better on a server that has lot of activity (lot of connections etc). Our db server runs at about 75-85% cpu usage daily and this particular SP accounts to 13% CPU usage for 2000+ executions. If the data set involved in cursors is small, is it worth the trouble changing them to set based approaches? Am I doing right to change this SP to setbased approach.

Cursor Looping Versus Set-based Queries
I know this question has been asked. And the usual answer is don't usecursors or any other looping method. Instead, try to find a solutionthat uses set-based queries.But this brings up several questions / senarios:* I created several stored procedures that take parameters and insertsthe data into the appropriate tables. This was done for easy access/usefrom client side apps (i.e. web-based).Proper development tactics says to try and do "code reuse". So, if Ialready have stored procs that do my logic, should I be writing asecond way of handling the data? If I ever need to change the way thedata is handled, I now have to make the same change in two (or more)places.* Different data from the same row needs to be inserted into multipletables. "Common sense" (maybe "gut instinct" is better) says to handleeach row as a "unit". Seems weird to process the entire set for onetable, then to process the entire set AGAIN for another table, and thenYET AGAIN for a third table, and so on.* Exception handling. Set based processing means that if one row failsthe entire set fails. Looping through allows you to fail a row butallow everything else to be processed properly. It also allows you togather statistics. (How many failed, how many worked, how many wereskipped, etc.)?? Good idea ?? The alternative is to create a temporary table (sandboxor workspace type thing), copy the data to there along with "status" or"valdation" columns, run through the set many times over looking forany rows that may fail, marking them as such, and then at the end onlydealing with those rows which "passed" the testing. Of course, in orderfor this to work you must know (and duplicate) all constraints so youknow what to look for in your testing.

Breakout Records Based On UNIT Total Without Cursor
I have a set of revenue records where there is a UNIT column and a REVCHARGE column. What I need to do is breakout the records into single records where the unit count is > 1 and calc the actual charge: Ex: Units REVCHG FIELD_A FIELD_B ..... 3 3.00 ABCD EFGH Needs to be converted to: Units REVCHG FIELD_A FIELD_B ..... 1 1.00 ABCD EFGH 1 1.00 ABCD EFGH 1 1.00 ABCD EFGH The calc is obvious but how can I do this with a cursor but would like to do it without a cursor if possible? Anybody got an idea? Thanks.

Moving Average Using Select Statement Or Cursor Based?
ID DATE(dd/mm/yy) TYPE QTYIN COST_IN_AMT COST_OUT_AMT(MOVING AVERAGE) 1 01/01/2007 PURCHASE 10 1000 2 01/01/2007 PURCHAES 5 1100 3 01/01/2007 SALES -5 *TobeCalculated 4 02/01/2007 Purchase 20 9000 5 02/01/2007 SALES -10 *TobeCalculated 5 02/01/2007 purchase 50 8000 6 03/01/2007 Sales -10 *TobeCalculate 7 01/01/2007 Purchase 20 12000 I have a table when user add new sales or puchase will be added to this table ITEM_TXNS. The above date is part of the table for a ProductID . (The field is removed here) In order to calculate the balance amount using moving average, I must calculated the cost_out_amt first on the fly. When user add new sales I also need to determine the cost/unit for a product id using moving average. The problem is I can not just use sum, because i need to determine cost_out_amt for each sales first which will be calculated on the fly. The reason i dont store the cost_out_amt (instead calculate on the fly) because User could Edit the previous sales/purchase txn or Insert new sales for a previous date. Example THe record with ID 9. By Adding this txn with ID 9, would cause all the cost_out_amt will be incorrect (Using moving Average) if i store the cost_amout_out on entrying txn and need to be recalculated. Instead I just want to calculate on the fly and able to determine the cost avr for a specific point of time. Should I just use Cursor and loop all the record and calculate the cost or maybe I can just use on Select Statement?

Help Cursor Based Stored Procedure Is Getting Slower And Slower!
I am begginner at best so I hope someone that is better can help.I have a stored procedure that updates a view that I wrote using 2cursors.(Kind of a Inner Loop) I wrote it this way Because I couldn'tdo it using reqular transact SQL.The problem is that this procedure is taking longer and longer to run.Up to 5 hours now! It is anaylizing about 30,000 records. I thinkpartly because we add new records every month.The procedure works like this.The first Cursor stores a unique account and duedate combination fromthe view.It then finds all the accts in the view that have that account duedatecombo and loads them into Cursor 2 this groups them together for datamanipulation. The accounts have to be grouped this way because aaccount can have different due dates and multiple records within eachaccount due date combo and they need to be looked at this way aslittle singular groups.Here is my procedure I hope someone can shead some light on this. Myboss is giving me heck about it.

SOLUTION! - VB.NET 2005 Express And SQL Server 2005 - NOT Saving Updates To DB - SOLUTION!
VB.NET 2005 Express and SQL Server 2005 Express - NOT saving updates to DB - SOLUTION! ----------------------------------- The following article is bogus and confusing: How to: Manage Local Data Files - Setting 'Copy to Output Directory' to 'Do not copy' http://msdn2.microsoft.com/en-us/library/ms246989.aspx You must manually copy the database file to the output directory AFTER setting 'Copy to Output Directory' to 'Do not copy'. Do not copy The file is never copied or overwritten by the project system. Because your application creates a dynamic connection string that points to the database file in the output directory, this setting only works for local database files when you manually copy the file yourself. You must manually copy the database file to the output directory AFTER setting 'Copy to Output Directory' to 'Do not copy'. ----------------------------------- The above article is bogus and confusing. This is rediculous! This is the most vague and convoluted bunch of nonsince I've ever come accross! Getting caught out on this issue for the 10th time! And not being able to find an exact step-by-step solution. -------------------------- I've tried it and it doesn't work for me. Please don't try what the article eludes to as I'm still sorting out exactly what is supposed to be happening. If you have a step-by-step procedure that can be reproduced this properly please PM me. I would like to test its validity then update this exact post as a solution rather than just another dicussion thread. Many thanks. This is the exact procedure I have come up with: NOTE 1: DO NOT allow VB.net to copy the database into its folders/directorys. NOTE 2: DO NOT hand copy the database to a folder/directory in your project. Yes, I know its hard not to do it because you want your project nice and tidy. I just simply could NOT get it to work. You should NOT have myData.mdf listed in the Solution Explorer. Ever. Create a folder for your data following NOTE 2. Copy your data to that folder. * mine was C:mydatamyData.mdf Create a NEW project. Remove any Data Connections. ( no matter what) Save it. Data | View Data Sources Add New Data Source select NEW CONNECTION ( No Matter what, do it! Select the database. * again mine was C:mydatamyData.mdf Answer NO to the question: Would you like to copy the file to your project and modify the connection? - NO ( no matter what - ANSWER NO ! - Absolutely NO ) Then select the tables you want in the DataSet. and Finish. To Test ---------- From the Solution Explorer | click the table name drop down arrow | select details Now Drag the table name onto the form. The form is then populated with a Navigation control and matching Labels with corresponding Textboxes for each field in the table. Save it. 1) Run the app. Add one database record to the database by pressing the Add(+) icon Just add some quick junk data that you don't mind getting lost if it doesn't save. YOU MUST CLICK THE SAVE ICON to save the data you just entered. Now exit the application. 2) Run the app again. And verify there is one record already there. Now add a second database record to the database by pressing the Add (+) icon. NOW add some quick junk data that you WILL intentionally loose. *** DO NOT *** press the save icon. Just Exit the app. 3) Again, Run the app. Verify that the first record is still there. Verify that the Second record is NOT there. Its NOT there because you didn't save the data before exiting the app. Proving that YOU MUST CLICK THE SAVE ICON to save the data you just entered. Also proving you must add your own code to catch the changes and ask the user to save the data before exitiing or moving to another record. As a side note, since vb.net uses detached datasets, (a copy/snapshot of the dataset in memory and NOT directly linked to the database) the dataset will reflect all changes made when moving around the detached datasets. YOU MUT REMEMBER TO SUBMIT YOUR CHANGES TO THE DATABASE TO SAVE THEM. Otherwise, they will simply be discarded without notice. Whewh! I hope this saves me some time the next time I want to start a new database project. Oh, and uh, for anyone else reading this post. Thanks, Barry G.

Avoiding Compilation
Using small stored procs or sp_executesql dramatically reduces the number ofrecompiles and increases the reuse of execution plans. This is evident fromboth the usecount in syscacheobjects, perfmon, and profiler. However I'm ata loss to determine what causes a compilation. Under rare circumstances theusecount for Compiled Plan does not increase as statements are run. Seemsto correspond to when there is no execution plan. It would seem to me thatcompilation is a resource intensive task that if possible (data and schemaare not changing) should be held to a minimum.How does one encourage the reuse of compile plans?Is this the same as minimizing compilation?Looks like some of this behavior is changing in SQL 2005....Thanks,Danny

Avoiding Deadlock
I have a stored procedure spUpdateClient, which takes as params a number of properties of a client application that wants to register its existence with the database. The sp just needs to add a new row or update an existing row with this data. I tried to accomplish this with code somethign like this. (The table I'm updating is called Client, and its primary key is ClientId, which is a value passed into the sp from the client.) IF (SELECT COUNT(ClientId) FROM Clients WHERE ClientId=@ClientId) = 0 BEGIN -- client not found, create it INSERT INTO Clients (ClientId, Hostname, Etc) VALUES (@ClientId, @Hostname, @Etc) END ELSE BEGIN -- client was found, update it UPDATE Clients SET Hostname=@Hostname, Etc=@Etc WHERE ClientId=@ClientId END But the client apps call this every second or so, so soon enough I started getting primary key violations. It looks like one client would make two calls nearly at the same time, both would get a 0 value on the SELECT line, so both would try to insert a new row with the same ClientId. No good. So then I added SET TRANSACTION ISOLATION LEVEL SERIALIZABLE BEGIN TRANSACTION at the top, and a COMMIT at the bottom. I thought the first one in would get to run the whole sp, and the next one in would have to wait for the first to be done. Instead I'm now getting deadlock errors. If I understand the docs right, that's because the exclusive lock is not placed on the Clients table until the INSERT happens, not at the SELECT. So when two calls to the sp happen at nearly the same time (call them A and B), A does the SELECT and that locks Clients so nobody else can update it. Then B does the SELECT, locking Clients so nobody else (including A) can update it. Now A needs to exclusively lock Clients to do its INSERT, but B still has that read lock on it, and they're deadlocked. I could catch the deadlock in my client app after SQL Server kills one of the transactions, but it seems to me there should be some way to set a lock at the top of the sp that says "nobody else can enter this sp until I exit it". Any such thing? Thanks. Nate Hekman

Avoiding Caching
I'm trying to performance tune a procedure and am sort of being thwarted by caching. When I first run the procedure, it takes a few seconds which is too long in this case. Subsequent executions in Management Studio are nearly instantaneous, though, which I imagine is due to caching and does not reflect the behavior of the procedure in production. Is there a way to disable caching so that each execution of the procedure in Management Studio will be consistent and reflect the "first run" performance?

Avoiding SQL Injection With Dynamic SQL
I am exclusively using Stored Procedures to access the database, i.e. there are no Ad-Hoc SQL statements anywhere in the C# code. However, one thing I need to be able to do is to allow filtering for data grids on my ASP.NET page. I want to do the filtering in the Stored Procedure using Dynamic SQL to set the WHERE clause. However, one fear of mine is SQL injection from the client. How can I avoid arbitrary SQL injection, yet still allow for a dynamic WHERE clause to be passed into the stored procedure? Jason Pacheco

Avoiding Time-outs
The C++ application calls the database to look up property data. Onetroublesome query is a function that returns a table, finding data whichis assembled from four or five tables through a view that has a join,and then updating the resulting @table from some other tables. Thereare several queries inside the function, which are selected accordingto which parameters are supplied (house #, street, zip, or perhaps parcelnumber, or house #, street, town, city,...etc.). If a lot of parametersare provided, and the property is not in the database, then several queriesmay be attempted -- it keeps going until it runs out of queries or findssomething. Usually it takes ~1-2 sec for a hit, but maybe a minute insome failure cases, depending on the distribution of data. (~100 milproperties in the DB) Some queires operate on the assumption the input datais slightly faulty, and take relatively a long time, e.g., if WHEREZIP=@Zip fails, we try WHERE ZIP LIKE substring(@Zip,1,3)+'%'. Whileall this is going on the application may decide the DB is never going toreturn, and time out; it also seems more likely to throw an exception thelonger it has to wait. Is there a way to cause the DB function to fail ifit takes more than a certain amount of time? I could also recast it asa procedure, and check the time consumed after every query, and abandonthe search if a certain amount of time has elapsed.Thanks in advance,Jim Geissman

Avoiding Nested Cursors
I have a Master/Detail table setup - let's call the master "Account" and the detail "Amount". I also have a "black box" stored procedure (BlackBox_sp) which carries out a lot of complex processing. What I need to do is, for each Account, I need to iterate thtough it's Amount records and call the black box each time. Once I've finished going through all the Amount records, I need to call the black box again once for the Account. This must be done with the Account & Amount rows in a specific order. So I have something along the lines of Code Block DECLARE Total int DECLARE Account_cur OPEN Account_cur FETCH NEXT FROM Account_cur WHILE FETCH_STATUS = 0 BEGIN SET Total = 0 DECLARE Amount_cur OPEN Amount_cur FETCH NEXT FROM Amount_cur WHILE FETCH_STATUS = 0 BEGIN SET Total = Total + Amount EXEC BlackBox_sp (Amount) END CLOSE Amount_cur EXEC BlackBox_sp (Total) END CLOSE Account_cur Any tips on another approach would be appreciated given the contraints I have.

Avoiding Subselect Query
Hi, Hope someone could help me in revising a long running query. Here is the query select * from table1 where classid is null and productid not in ( select productid from table1 where classid = 67) In here table1 could have several occurance of productid in which productid could have different classid. The possible values of classid are: NULL,1,2,3,67. Basically I am looking for all records whose classid is null but should never had an instance in table1 where its classid is 67. Do you have something like a "join" statment that will only include all records in the left table that is not in the right table? Hope someone could help me with this. Thanks in advance. -Ruel

Help With Where Not Exists / Avoiding Loops
I am trying to figure out an efficient way of comparing two tables of identical structure and primary keys only I want to do a join where one of the tables reveals values for records which have been modified and/or updated. To illustrate, I have two tables in the generic form: id-dt-val For which the 'val' in table 2 could be different from the 'val' in table 1 - for a given id-dt coupling that are identical in both tables. Does anyone know of an efficient way I could return all id-dt couplings in table 2 which have values that are different from those with the same id-dt couplings in table 1? NOTE: I am asking this because I am trying to avoid explicit comparisons between the 'val' columns. The tables I am working with in actuality have roughly 900 or so columns, so I don't want this kind of a monster query to do (otherwise, I would simply do something like where a.id = b.id and a.dt = b.dt and a.val <> b.val) - but this won't do in this case. As a sample query, I have the following script below. When I attempt the where not exists, as you might expect, I only get the one record in which the id-dt coupling is different from those in table 1, but I'm not sure how to return the other records where the id-dt coupling is the same in table 1 but for where modified values exist: create table #tab1 ( id varchar(3), dt datetime, val float ) go create table #tab2 ( id varchar(3), dt datetime, val float ) go insert into #tab1 values ('ABC','01/31/1990',5.436) go insert into #tab1 values ('DEF','01/31/1990',4.427) go insert into #tab1 values ('GHI','01/31/1990',7.724) go insert into #tab2 values ('XYZ','01/31/1990',3.333) go insert into #tab2 values ('DEF','01/31/1990',11.111) go insert into #tab2 values ('GHI','01/31/1990',12.112) go select a.* from #tab2 a --Trouble is, this only returns the XYZ record where not exists (select b.* from #tab1 b where a.id = b.id and a.dt = b.dt) go drop table #tab1 drop table #tab2 go I really dont' want to have to code up a loop to do the value by value comparison for inequality, so if anyone knows of an efficient set-based way of doing this, I would really appreciate it. Any advice appreciated! -KS

Avoiding Query In Loop
Hello all, I currently have an asp script that is generating a 12 month rolling report. From asp I'm running a for loop with 12 iterations, each one sending the following query: select count(a.aReportDate) as ttl from findings f left outer join audits a on a.aID = f.auditID where f.findingInvalid <> 1 and month(aReportDate) = " & Mo & " and year(aReportDate) = " & Yr where the Mo and Yr variables are incremented accordingly. I actually have 4 sets of data being pulled back to populate a graph, so this results in 48 queries with each page load! Obviously not ideal. So I'm hoping to reduce this to 4 queries. I was playing with the following in enterprise manager: DECLARE @DT DATETIME DECLARE @CNT INT SET @DT = '10/31/07' SET @CNT = 1 WHILE(@CNT < 12) BEGIN select count(a.aReportDate) as ttl from findings f left outer join audits a on a.aID = f.auditID where f.findingInvalid <> 1 and month(aReportDate) = month(@DT) and year(aReportDate) = year(@DT) SET @CNT = @CNT + 1 END I haven't yet added any logic to increment the date, but my concern is that it looks like it is returning 12 separate results. Is there any way to combine this all into one resultset that will be passed back to my asp script? Hopefully this makes sense? Suggestions on a completely different approach would also be welcome. Thanks!

Temporarily Avoiding Writing Into Trans Log
Guys, Is there a way to temporarily disable logging into the transaction log. In our system, we perform purging of our database every night, where the purging consists of 2 steps: 1. For each table, insert the data, to be deleted, into a corresponding "purged" table, to remain there for one day only. 2. For each table, delete the unnecessary data (i.e. same data stored in purged tables in step 1) During these 2 steps, the transaction log grows, and since we perform the transactional log back up, the back up at that time is huge. We are running a bit low on the hard disk space and I'd like to disable logging into the transaction log when these operations are performed. I really don't care about being able to recover this data. I thought that one option is to set the database to simple recovery, then perform the purging of the database, and then change back to full. However, I think that trans log can grow even if recovery model is simple [although you won't be able to retrieve any changes]. So, is there a way to delete a portion of a table [or insert into it] so that no data is written to a transaction log (I know that we can use TRUNCATE if we need to remove whole table without logging)? Thanks a lot

Avoiding OS 1450 Errors On SQL2KEE/Win2K3EE
Just a point of information for anyone running SQLServer 2000 Enterprise Edition on Windows Server 2003 Enterprise Edition, using extended memory (AWE enabled, /PAE). We had lots of trouble with O/S 1450 errors and so forth, when the server was configured with the /3GB switch in boot.ini. We found articles online (go Google!) that the reason might be related to the PTE tables, and the ability of the OS to manage the memory mapping as the PTE tables become filled. In fact, with /3GB in, the PTE tables were only about 20000 entries. With the /3GB out, the paging tables got to about 180000 entries, nearly 10x increase. This is the key to avoiding OS 1450 errors on Win2K3EE/SQL2KEE installations that use extended memory.

Selecting From Multiple Tables Avoiding Duplicates
Hi I currently have two tables called Book and JournalPaper, both of which have a column called Publisher. Currently the data in the Publisher column is the Publisher name that is entered straight into either table and has been duplicated in many cases. To tidy this up I have created a new table called Publisher where each entry will have a unique ID. I now want to remove the Publisher columns from Book and JournalPaper, replace it with an ID foreign key column and move the Publisher name data into the Publisher table. Is there a way I can do this without duplicating the data as some publishers appear several times on both tables? Any help with this will be greatly appreciated as my limited SQL is not up to this particular challenge!!! Thanks!

Avoiding Clear Text Passwords And Editing Of Packages
Hi! I have an SQL Server where only a group of sysadmins have access to install DTSX packages. Those DTSX packages are developed by another team that does not have access to the production SQL Server. They use their own SQL Server. In order to make it as simple as possible to install these packages by the sysadmins, I suggested the use of configuration files. The files are associated with the job that executes the package and all that has to be done to install the package is copy it to the file system or import it into the SQL Server. Developers use their configuration file, sysadmins user theirs. Nothing new here. The problem is that some of the packages have to access some old systems and we cannot use integrated authentication. We have to use SQL authentication and therefore specify a user account and password in the connection string. If this is stored in the configuration file, it is available in clear text! If I store the configuration in the package itself using ProtectSensitiveWithPassword protection level, the sysadmins will have to edit every DTSX package to reset the connections to the production environment (the developers always send them with their development configurations) and I don't want that. If I store it in a SQL Server database, it seems the sysadmins also have to edit the package to point the package configuration to the correct database and set the configuration filter. Another solution is to store the credentials in clear text in the configuration file but set the file system permissions on that file so only the account that executes the package can read them (this is what I'm implementing if nothing better comes up...) Is there any other way to do this? Am I doing something wrong? Thanks in advance.

Dynamic Cursor Versus Forward Only Cursor Gives Poor Performance
Hello,I have a test database with table A containing 10,000 rows and a tableB containing 100,000 rows. Rows in B are "children" of rows in A -each row in A has 10 related rows in B (ie. B has a foreign key to A).Using ODBC I am executing the following loop 10,000 times, expressedbelow in pseudo-code:"select * from A order by a_pk option (fast 1)""fetch from A result set""select * from B where where fk_to_a = 'xxx' order by b_pk option(fast 1)""fetch from B result set" repeated 10 timesIn the above psueod-code 'xxx' is the primary key of the current Arow. NOTE: it is not a mistake that we are repeatedly doing the Aquery and retrieving only the first row.When the queries use fast-forward-only cursors this takes about 2.5minutes. When the queries use dynamic cursors this takes about 1 hour.Does anyone know why the dynamic cursor is killing performance?Because of the SQL Server ODBC driver it is not possible to havenested/multiple fast-forward-only cursors, hence I need to exploreother alternatives.I can only assume that a different query plan is getting constructedfor the dynamic cursor case versus the fast forward only cursor, but Ihave no way of finding out what that query plan is.All help appreciated.Kevin
