I know this question has been asked. And the usual answer is don't use
cursors or any other looping method. Instead, try to find a solution
that uses set-based queries.
But this brings up several questions / senarios:
* I created several stored procedures that take parameters and inserts
the data into the appropriate tables. This was done for easy access/use
from client side apps (i.e. web-based).
Proper development tactics says to try and do "code reuse". So, if I
already have stored procs that do my logic, should I be writing a
second way of handling the data? If I ever need to change the way the
data 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 multiple
tables. "Common sense" (maybe "gut instinct" is better) says to handle
each row as a "unit". Seems weird to process the entire set for one
table, then to process the entire set AGAIN for another table, and then
YET AGAIN for a third table, and so on.
* Exception handling. Set based processing means that if one row fails
the entire set fails. Looping through allows you to fail a row but
allow everything else to be processed properly. It also allows you to
gather statistics. (How many failed, how many worked, how many were
skipped, etc.)
?? Good idea ?? The alternative is to create a temporary table (sandbox
or workspace type thing), copy the data to there along with "status" or
"valdation" columns, run through the set many times over looking for
any rows that may fail, marking them as such, and then at the end only
dealing with those rows which "passed" the testing. Of course, in order
for this to work you must know (and duplicate) all constraints so you
know what to look for in your testing.
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
I am creating an SSIS Script Task that will be used to process SSAS dimensions and partitions and ideally log the details of each in a table. Any info on the benefits or drawbacks of using the built-in SSAS parallel processing as opposed to doing it manually in a multi-threaded "Parallel.Foreach" loop using the .NET AMO library.
In my testing, when I use a Parallel.foreach loop, I am able to obtain and log information about the object such as end time and time to process immediately after each object is processed. This allows me to keep a history of processing time for each object:
public void processDimensions(Server Server, Database Database, ProcessType processType) { Parallel.ForEach(Database.Dimensions.OfType<Microsoft.AnalysisServices.Dimension>(), d => { DateTime beginTime = DateTime.Now; try { d.Process(processType);
[code]....
If circumventing the built-in SSAS parallel processing is not best practice I'd like to know in advance before I go too far down that path.
I have always been told that Cursors create a lot of overhead and consume a lot of system resources. Is it faster to store the data in a temp table and loop through it by using Select Top 1 and Delete statements or by using a static, Forward-Only Cursor? Both ways store the data in TempDB, but doesn't the While Loop statement generate more IO's than the Cursor? In theory, I am thinking that the Cursor is better. Any info will be appreciated.
I need to create a cursor that will loop through my customer database to return matching rows of data based on my select statement criteria. I have written most of it based on what I remember from my limited SQL exposure at a previous job afew years ago, but I can't remember how to make the @cust_id varaible increment by 1 and loop to the end of the customer table.
Can anyone steer me in the right direction here please?

Hi, newbie here:I have created a small (5 fields) Access table which I will beconverting to MS-SQL Server format when the ASP code has beencompleted. It is basically a collection of links to news releases frommining companies. The group of people who will be browsing thisdatabase want to know if the news release pertains to their area.Sometimes the news release pertains to multiple areas if the miningproperties are scattered. Given the possibility of a one-to-manyrelationship, ie one news release, many areas, I created an additionaltable for the areas. I created the ASP code to pull down the newsrelease information, then loop through the area records such as:set RSNewsRelease = Server.CreateObject("ADODB.Recordset")NewsRelSQL = "Select date, company, title, newsreleaseID fromnewsreleases;"do while not RSNewsRelease.EOF'display news release date, company and titleresponse.write RSNewsRelease(0).Value & RSNewsRelease(1).Value &RSNewsRelease(2).Value'loop through areasset RSAreas = Server.CreateObject("ADODB.Recordset")'run querydo while not RSAreas.EOF'display areasLoopset RSAreas = nothingLoopIn other words, the only way I could get the results I wanted was toset the Recordset to nothing, then reset it with each iteration of theouter loop.Is there a better way to do this?Jules
I don't know what category would be appropriate for this question but security seems to be close enough.
I have this case scenario: I am running an automated application that extracts data from a web site and stores the data into a table on SQL server 2005. This information is not confidential in the extreme of social insurance #'s, bank account #s, but should not be seen by a typical employee (it has no use for them). After the data has been stored, it retrieves the data from the same table, processes it, and updates the same table. This application runs every hour infinitely.
Should all the insert, update, and select queries be stored under a stored procedure? I am not concern with performance. My concern would fall under design and security.
Is it worth to hide the details of inserting/updating/selecting behind a stored procedure? Or should I just allow the program to send select/update/insert SQL queries?
No employee (other then the developer and the DB admin) or customer ever access this table (They do not have permission from SQL). The username and passwords were created with security in mind.
When I try to repeat a query using cursors the first run is succesful but the second returns nothing; I then have to disconnect and reconnect to get the query to work again. Here's sample code (which does nothing except print returned items)
SET ANSI_NULLS ON SET ANSI_WARNINGS ON
declare @login sysname , @password sysname
declare sourcelogins cursor for
select name , password
from master.dbo.syslogins
open sourcelogins
while ( @@fetch_status = 0)
begin
fetch sourcelogins into @login , @password
print @login
end
close sourcelogins
deallocate sourcelogins
SET ANSI_NULLS OFF SET ANSI_WARNINGS OFF GO
First time through this prints all logins. Second time it returns "completed successfully" and prints nothing. Similarily, if I run two queries consecutively, the second using a differenct cursor name, the second still fails. Any ideas?
Does anyone have any good references they could recommend on Cursorbased SQL writing? I have to create SQL that can loop though recordssimular to VB loops and I have been told that this is the way to go.Any recommendations would be helpful.
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
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.
Hey All, I am trying to convert cursor based stored proc in to set based simple statements stored proc. As this stored proc has created alot of performance issues. I am confuse now as I spent my most of time creating this stored proc. Please advise how can I convert this stored proc into set base simple statment.
Thanks in advance.

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:

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?
I think I got all my create table statements are correct.

Im thinking I might have a problem with my create table statement and/or primary key statements?
Using SQL Server 2000, I need to perform date range type queries that involve my company's Fiscal Year, which is not the same as the calendar year. My company's Fiscal Year if from Sept 1 to Aug 31, where Aug 31st year determines the Fiscal Year. For example, since today's date is 09/20/2006, the current Fiscal Year is 2007.
An example of a typical query requirement:
Find all the sales figures to-date for the current Fiscal Year. So, a WHERE clause will consist of a date range query from 09/01/2006 to 8/31/2007.
Initially, I created a Function to find the current Fiscal Year based on the current date, by calling the GETDATE() function and passing the results to the following function:
CREATE FUNCTION dbo.fnGetFY (@CurrentDatetime datetime) RETURNS int AS BEGIN DECLARE @FY int IF (SELECT MONTH(@CurrentDatetime)) > 8 SET @FY = YEAR(@CurrentDatetime) + 1 ELSE SET @FY = YEAR(@CurrentDatetime) RETURN(@FY) END
So, the view queries that involve the Fiscal Year call the above function.
However, these function calls drag down the VIEW query response time to the point where the time is either unacceptable or an ODBC Timeout occurs, even with Query Analyzer.
Is there a way to create a Global server parameter to hold the current Fiscal Year value, so function calls are not necessary? Or set Fiscal Year date ranges for a database or server system parameter?
Does anyone know of a efficent, response timewise, way to handle Fiscal Year date range queries?
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.

Once its down it moves to the next category and does the same and so on. Does anyone know the trick ?
STATIC Defines a cursor that makes a temporary copy of the data to be used by the cursor. All requests to the cursor are answered from this temporary table in tempdb; therefore, modifications made to base tables are not reflected in the data returned by fetches made to this cursor, and this cursor does not allow modifications
It say's that modifications is not allowed in the static cursor. I have a questions regarding that
Static Cursor declare ll cursor global static for select name, salary from ag open ll fetch from ll
while @@FETCH_STATUS=0 fetch from ll update ag set salary=200 where 1=1
close ll deallocate ll
In "AG" table, "SALARY" was 100 for all the entries. When I run the Cursor, it showed the salary value as "100" correctly.After the cursor was closed, I run the query select * from AG.But the result had updated to salary 200 as given in the cursor. file says modifications is not allowed in the static cursor.But I am able to update the data using static cursor.

my question is, how to join the part 1 n part 2? is there posibility?
I'm sorry to be ignorant on this point. It seems trivial, but what's the difference between @@ and @ when using variables in T-SQL? I have a developer that always uses @@ for local variables and @ for reference variables (meaning variables declared as parameters for a stored procedure or function).
Is that purely stylistic? Is it a holdover from some previous version? Or is it a legitimate best practice that I've not seen before?
My google-shui is weak today; I found nothing when searching.
Both these tables contain considerable amounts of rows, but over time tableA will end up containing orphaned values (i.e. the a_id is not used in tableB) and this problem cannot be rectified by setting, for example, cascade deletes.
To fix this problem I decided to write a simple stored procedure to purge all values in tableA where its a_id is not used in tableB :
DELETE FROM tableA WHERE a_id NOT IN (SELECT a_id FROM tableB)
Now although the following document relates to postgres :
I wonder if anyone else out there has the same impression that I have: I find that DTS works much better than SSIS.
I find that DTS is so easy to use and reliable: it gets the job done and fast! On the other hand, SSIS seems to be so needlessly complex that it takes hours of troubleshooting just to get it to work, and sometimes it doesn't work at all. For example I have just spent hours trying to get SSIS to import a flat file with 300,000 rows. It just crashes and doesn't even give an error message so that one can fix it. On the other hand I have just now successfully accomplished the same task with DTS and it took me 5 minutes!
I honestly don't see a valid reason for using SQL Server 2005 instead of 2000. So far it's much more productive to use 2000.
I want to loop through a recordset and do inserts into another table based on each record.
The way I have been doing it is copy my key data into a temp table, Loop through temp finding the max ID Doing what I need to do, deleting the max, then finding the new max and looping until no records exist.
I know there has to be a better way. The table I am working with is millions of records. Thanks in advance, Chris Reeder
I need to loop through a set of tables and move the data through a data pump from one server to another. This set of tables is dynamic so I have greated a global recordset and the looping is working fine.
During the looping process I need to change the transformations for each table so the source, destination, and transformation of the datapump are correct for the next table in the loop. I am using a VBS to handle this right now but cannot get the transformation to change. I essentially want to auto-remap using a vbs script. Is this possible?
Hello clever people I have a table that holds duplicates that I want to change into a table that has no duplicates. The current table is this name compound_id integer name varchar(150) name_type integer
This table stores chemical names. There is no primary key in the table so there are multiple compound_id's. I think the original idea was to have four name-types 1 = chemical name 2 = a description of the chemical 3 = a synonym of the chemical 4 = a formula of the chemical
I have created a new table called compound_name with this structure
id int primary key (auto identity) compound_id int used as a foreign key compound_name varchar(150) compound_desc varchar(250) compound_synonym varchar(150) compound_formula varchar(50) compound_trade_nme varchar(50)
I have also started to populate the new table by running this code insert into compound_name(compound_id,compound_name) SELECT DISTINCT compound_id, name FROM dbo.name WHERE (name_type = 1)
Now I need to somehow loop through the name table getting distinct compound_id's, and perform a case when name_type = 2 (which is synonym name_type) Then inside the loop update compound_name.compound_synonym for each compound_id which matches name_type 2 Then case 3 do the same for name_type 3 which is the name_type for descripton Then case 4 do the same for name_type 4 which is the formula
