Using A Cursor As A Function Parameter
I've created a function that converts the rows of a column into a delimited string using a passed cursor and delimiter character. In the past I did this in Oracle and called it as shown in the following example: SELECT Table1.ID, Table1.FirstName, Table1.LastName, fnDelimitRows(CURSOR(SELECT Table2.CourseName FROM Table2 WHERE Table2.StudentID = Table1.ID), ',') AS AssignedCourses FROM Table1 23 John Smith CS101,MT200,BIO100 43 Julio Johnson CS200,ENG100,MT300 How would I pass a cursor into a function in SS like I did above in Oracle? Thanks!

Split Function With Cursor
Hi, I am trying to write a stored procedure that takes a comma separated letter. I have a split function that returns the splitted letters. I have select some values from the tables in the database where the title starts with each splitted letter. I thought I should use cursor that contains each letter and in the while loop i put my select statement with the conditions. Is this the correct way. Or are there any ideas for this? thanks, Regards, shakthi

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

Using A Scalar Valued Function As A Parameter Of A Table Valued Function?
Ok, I'm pretty knowledgable about T-SQL, but I've hit something that seems should work, but just doesn't... I'm writing a stored procedure that needs to use the primary key fields of a table that is being passed to me so that I can generate what will most likely be a dynamically generated SQL statement and then execute it. So the first thing I do, is I need to grab the primary key fields of the table. I'd rather not go down to the base system tables since we may (hopefully) upgrade this one SQL 2000 machine to 2005 fairly soon, so I poke around, and find sp_pkeys in the master table. Great. I pass in the table name, and sure enough, it comes back with a record set, 1 row per column. That's exactly what I need. Umm... This is the part where I'm at a loss. The stored procedure outputs the resultset as a resultset (Not as an output param). Now I want to use that list in my stored procedure, thinking that if the base tables change, Microsoft will change the stored procedure accordingly, so even after a version upgrade my stuff SHOULD still work. But... How do I use the resultset from the stored procedure? You can't reference it like a table-valued function, nor can you 'capture' the resultset for use using the syntax like: DECLARE @table table@table=EXEC sp_pkeys MyTable That of course just returns you the RETURN_VALUE instead of the resultset it output. Ugh. Ok, so I finally decide to just bite the bullet, and I grab the code from sp_pkeys and make my own little function called fn_pkeys. Since I might also want to be able to 'force' the primary keys (Maybe the table doesn't really have one, but logically it does), I decide it'll pass back a comma-delimited varchar of columns that make up the primary key. Ok, I test it and it works great. Now, I'm happily going along and building my routine, and realize, hey, I don't really want that in a comma-delimited varchar, I want to use it in one of my queries, and I have this nice little table-valued function I call split, that takes a comma-delimited varchar, and returns a table... So I preceed to try it out... SELECT *FROM Split(fn_pkeys('MyTable'),DEFAULT) Syntax Error. Ugh. Eventually, I even try: SELECT *FROM Split(substring('abc,def',2,6),DEFAULT) Syntax Error. Hmm...What am I doing wrong here, or can't you use a scalar-valued function as a parameter into a table-valued function? SELECT *FROM Split('bc,def',DEFAULT) works just fine. So my questions are: Is there any way to programmatically capture a resultset that is being output from a stored procedure for use in the stored procedure that called it? Is there any way to pass a scalar-valued function as a parameter into a table-valued function? Oh, this works as well as a work around, but I'm more interested in if there is a way without having to workaround: DECLARE @tmp varchar(8000) SET @tmp=(SELECT dbo.fn_pkeys('MyTable')) SELECT * FROM Split(@tmp,DEFAULT)

Calling A Function From A Function?
Hi All Yesterday Peso was gracious enough to help me with creating function/views/sp's I took those examples and extended what had from excel into function in SQL however I see myself repeating certain parts of the query and i'm wondering if there is a way to call a function (in part or in whole) from another function? Here are excerpts two functions I have: We'll call this function UserUsage() ------------------------------------ RETURN( SELECT ut.LastName, ut.FirstName, CEILING(Sum(hu.session_time)/ 60000) AS [Time Spent(MIN)], Max(hu.time_stamp) AS [Last Log Date], pct.Title, cat.topic_name FROM ZSRIVENDEL.dbo.UserTable ut, ZSRIVENDEL.dbo.history_usage hu, ZSRIVENDEL.dbo.pc_CourseTitles pct, ZSRIVENDEL.dbo.cam_topics cat WHERE ut.student_id = hu.student_id AND hu.course_id = pct.CourseID AND hu.topic_id = cat.topic_id AND ((ut.ClientID=@ClientID) AND (pct.ClientID=@ClientID) AND (ut.GroupID=3400) AND (hu.time_stamp>= @StartDate And hu.time_stamp< @EndDate) AND (hu.session_time<21600000)) GROUP BY ut.LastName, ut.FirstName, pct.Title, cat.topic_name ) and will call this function UserSummary(): ----------------------------------------- RETURN ( SELECTut.LastName, ut.FirstName, CEILING(SUM(hu.Session_Time) / 60000.0) AS [Time Spent(MIN)] FROM ZSRIVENDEL.dbo.UserTable AS ut INNER JOIN ZSRIVENDEL.dbo.History_Usage AS hu ON hu.Student_ID = ut.Student_ID WHERE ut.ClientID = @ClientID AND ut.GroupID = 3400 AND hu.Time_Stamp >= @StartDate AND hu.Time_Stamp < @EndDate AND hu.Session_Time < 21600000 GROUP BY ut.LastName, ut.FirstName ) As you can see the first part of the both query are simlar. In particular the: SELECTut.LastName, ut.FirstName, CEILING(SUM(hu.Session_Time) / 60000.0) AS [Time Spent(MIN)] and also the variables @StartDate and @EndDate. In C# it would create a method and just call that method as well as the variables. However i'm not sure how to do that with sql functions. Could someone shed some light please? Thank you!

Need Help With A Cursor
I hope this is the appropriate forum for this question, if not then I apologize. I've got a SQL Server 2000 stored procedure that returns data to be used in a crystal report in Visual Studio 2005. Most of the stored procedure works well, but there is a point where I need to calculate an average number of days been a group of date pairs. I'm not familiar with cursors, but I think that I will need to use one to achieve the result I am looking for so I came up with the code below which is a snippet from my stored procedure. In this part of the code, the sp looks at the temporary table #lmreport (which holds all of the data that is returned at the end to crystal) and for every row in the table where the terrid is 'T' (the territory is domestic), it selects all of those territories from the territory table and loops through them to determine the date averages (by calling a nested stored procedure, also included below) for each territory and then updates #lmreport with that data. When I try to run the stored procedure, I get "The column prefix '#lmreport' does not match with a table name or alias name used in the query." on the line indicated. Does anyone have any idea what might be wrong or if this will even work the way I need it to? Thank you in advance.

Need Cursor Help
Hello, I'm trying to construct a cursor that will sequentually increment a number and then update a column with the incremented number. My propblem is that all the rows in the table are being updated with the base number +1. So all rows are updated with 278301. BUT, what I really want is for only the items with adrscode of 'bill to' to be given an incremented number. For example, if there are only five rows of 100 with an adrscode = 'bill to' then only five rows will be updated and the value of the custnmbr should be, 278301, 278302, 278303 .....

Is Cursor Best Way To Go?
I need to get two values from a complex SQL statement which returns a singlerecord and use those two values to update a single record in a table. Inorder to assign those two values to variables and then use those variablesin the UPDATE statement, I created a cursor and used Fetch Next.... Into.This way, I only have to call the complex SQL once instead of twice.This seems like the best way to go. However, I've always used cursors forscrolling through resultsets. In this case, though, there is just a singlerecord being returned, and the cursor doesn't scroll.Is that the most efficient way to go, or is there a better way to be able touse both values from the SQL statement without having to call it twice?Thanks.

Count the number of records in thetemporary table and loop though the table selecting the values andbuilding the string where the identity column = the loop number.Is this more or less efficient than just using a cursor? If so why isit more or less efficient?Please explain in detailThank You,Jim Lewis

Cursor Help PLEASE!
Yes, I know that cursors are gauche, but I can't see a solution usingqueries and I'm pretty adept at them. This will be running once a dayin the wee small hours when minimal server activity will be takingplace, it will be handling 700-1000ish records. The box is a P4/SQL2000 with lots of ram and multiple CPUs.The code for creating and populating the table in question follows thecursor code.The application is for medical transport billing. We take people tothe doctor and home again and the health plan pays us. A one-waytrip, home -> doctor, is a single ‘line item'. A round trip, home ->doctor -> home is rolled up, the charge summed, and billed as a singleline item. A three-leg, home -> doctor -> pharmacy -> home, is billedas three line items.This code is just for identifying the data, once this works correctlyI'll add the code in for doing the rollup and I'm confident I canhandle that.If I ruled the world, every leg of every trip would be a single lineitem and I wouldn't have to deal with this rollup BS, but I don't makethe policy, I just have to code it. <g>A trip is a round trip if the date, account number, and passenger nameis the same and the origin street of record X equals the destinationstreet of record X+1. The problem is that X+1 could be the start of around trip and X+2 could be the completing leg of a round trip. Soyou could have a scenario of hospital -> home -> doctor -> home inwhich X is one-way and X+1 & X+2 form a round trip.BLERG!

What Is A Cursor?
I had a friend write a stored procedure to perform a function for oneof my clients. What he wrote doesn't fully do what I need, and I hopeto finish it myself. I have programming sense, but not so much withSQL.I'm trying to figure out the code, and he has used something called a"cursor." I'm not sure whether this is an SQL construct or a structurethat he has just labeled "cursor." My guess is that it is an SQLconstruct. Can anyone give me a quick run down of how this works?sincerely,Tyler H.-----------------------------------------------<a href="http://www.seearoomhawaii.com/bed-breakfasts/">bed &breakfasts in Hawaii</a>

It Is Possible With Cursor?
I need to fill a cursor with 3 columns. A want to use a Select sprocs (for re-use de code), but this sproc return 15 columns and the 3 a need was not the 3 frist. :confused: Do I need to map the 15 columns with 15 variables locally? Or they have a way easier? Thanks

Can I Use SQL Instead Of Cursor?
Hi, I'm currently converting a VB function to SQL-Server. The function uses a cursor to find the "terms of delivery" (TOD) with the highest priority. I have a table with articlenumber, tod (and lots of other columns that doesn't matter now) ABC123 , AFG ABC123 , AFG ABC123 , BGH ABC123 , BGH ABC123 , CDD "CDD" has the highest priority and therefore ALL with the same articlenumber should use that tod. The existing function uses a cursor and loops through a recordset and updates every row with the same articlenumber as the current row with the tod with the highest priority (of the ones read) with the same articlenumber. One update per row takes "forever" to run... I figured it would be possible to select the tod with the highest priority for one articlenumber into a temp table and then do ONE update to set the tod on all rows...

Can't Use Cursor With SP
Hi I have a SP and in it I call another SP which returns one row in one column, I need to concatenate the value (varchar) to the query in the first SP. I tried to use cursor with FAST_FORWARD to fetch the result and concatenate it, but I get an error, here is what I tried: DECLARE Cur CURSOR FAST_FORWARD FOR SP_Something @SomeValue So is it possible to use cursor on SP ? And if it's possible so how ??? Thanks, Inon.

How To Do This Without Using A Cursor?
I am in the last stages of designing a forecasting "engine" for my company, and I'm stuck on something that seems simple in comparison to everything else I've done so far. I have product ABC, and it's total sales forecast is 15 units. I split the forecast into 2 different locations, based on an established percentage. In this case, I'll say 67% in location 'OH', and 33% in location 'AL' That's 10 units 'OH' and 5 units 'AL'. Then I get my actual orders by location, and compare them to the forecast. If the orders exceed the forecast, I'll use orders, otherwise, I use forecast. Whenever I do that, I need to reduce the forecast for the other location, in order to keep the total forecast of 15 whole. (It is not possible for total orders to exceed total forecast, I've already dealt with that.) CREATE PROCEDURE tempSelect AS CREATE TABLE #tmpTest ( parent char(2), proj_ship real, open_ord real, ) insert into #tmpTest (parent, proj_ship, open_ord) select 'OH', 10, 4 insert into #tmpTest (parent, proj_ship, open_ord) select 'AL', 5, 7 SELECT PARENT, 'UNITS' = ??? FROM #TMPTEST DROP TABLE #TMPTEST GO I need help with '???' in the query. The result set I am looking for is: OH 8 AL 7

Trying To NOT Use A Cursor...
I need to write a sproc to supply records for a report. The boss has asked "Of all the tons on order right now, how much is already in inventory, and how much needs to be produced." And "Apply the same logic to just the orders that came in yesterday." It would have been easy, if he hadn't asked for the second part, because now I have to look at each product on each order, rather than comparing total orders for a product to total available inventory. Here's some sample data for what I need to do: CREATE TABLE ORDER_ITEM ( ORDER_NUM VARCHAR(10), SHIP_DATE SMALLDATETIME, PRODUCT VARCHAR(10), ORD_TONS REAL) INSERT INTO ORDER_ITEM (ORDER_NUM, SHIP_DATE, PRODUCT, ORD_TONS) SELECT '001', '3/1/2006', 'ABC', 4 UNION ALL SELECT '002', '3/4/2006', 'ABC', 2 UNION ALL SELECT '002', '3/4/2006', 'DEF', 6 UNION ALL SELECT '003', '3/7/2006', 'DEF', 8 CREATE TABLE PROD_INVENTORY ( PRODUCT VARCHAR(10), INV_TONS REAL) INSERT INTO PROD_INVENTORY (PRODUCT, INV_TONS) SELECT 'ABC', 5 UNION ALL SELECT 'DEF', 13 The final recordset needs to be something like: PRODUCT ORDER_NUM ORD_TONS SFI SFP END_INV ABC 001 4 4 0 1 ABC 002 2 1 1 0 DEF 002 6 6 0 7 DEF 003 8 7 1 0 SFI = Sales from Inventory SFP = Sales from production I need a little help in how to do a running inventory balance (END_INV) for each item. Once I have that, then I can calculate SFI and SFP. I could figure out how to do it with a cursor, but it would probably be pretty slow. I'll have about 10,000 records to sort thru, and of course there will be more columns than what I show here. Any ideas would be appreciated.

Do I Really Need A Cursor?

A BUG In Cursor Or What Is Going On???
Hi, I have created a cursor to select 5 rows from a table , then I put the cursor in a store procedure, when I test the cursor the firt time I get correct results, but when I test it again in the same query window NOTHING happen?.... is this a BUG or am I doing something wrong, by the way, when I execute the procedure in another query window, I get it right. In conclusion, whenever I run the procedure more than once in the same query window the second try fails...but when I go to another query window it works.. I appreciate if anyone can explain why? reagards Ali create procedure p_test_cursor as DECLARE RST CURSOR FOR SELECT counter,INVESTORID,BALANCE FROM BALANCE WHERE INVESTORID =300 OPEN RST DECLARE @COUNTER INT,@INVESTORID INT, @BALANCE MONEY -- putting rst col in @ WHILE @@FETCH_STATUS <>-1 -- mean when there is no error BEGIN SELECT @COUNTER ,@INVESTORID,@BALANCE UPDATE BALANCE SET OWNERSHIP =@COUNTER WHERE COUNTER =@COUNTER FETCH RST INTO @COUNTER ,@INVESTORID,@BALANCE END CLOSE RST DEALLOCATE RST

Each resume has a unique id. ie: Table 1 res_id fname lname userid pwd address city state etc... 100 John Doe jd ok xxxx xxxx xx xxxx 104 Sally May sm sm ccccc cc c cc ccc 643 John Doe jd ok ssss null null 1003 John Doe jd ok 123 elm Nome AK ... 5000 Tom Cat tc tc null null null I need to insert into Table 2 only the demographic information for each person appearing in Table 1. The catch is that Table 2 doesn't have the same unique id that appears in Table 1. userid and pwd are unique to Table 2 but are numerous in Table 1. Table 2 new_ident userid pwd address city state etc.. 10 jd ok 123 elm Nome AK .... 11 Sally May sm sm ccccc cc c cc ccc 12 Tom Cat tc tc null null null Basically I need to choose the most current "max(res_id)" occurance for John Doe above to get only one row out of his three rows. Then I need to get all the other unique rows from table 1. I hope that is clear. I was considering a cursor. Any ideas?? Troy

Can I Do This Without A Cursor?
Here's what I' trying to do... I am writing an application for a training facility. I have three tables in particular that I'm concerned with. Here they are with the relevent keys 1. Registrations - contains a customerid and a classid 2. Sessions - contains a classid (multiple sessions can exist for a class) 3. Attendence - contains a session and a customerid. Whenever I insert a session record for a class, I want to automatically create a corresponding record in the attendence table for every student in the class . My only thought is to create an insert trigger on the session table than creates creates a cursor containing the customerid for every student registered in the class. Then I can walk through the cursor and insert an Attendence record for each student. I really don't want to use a cursor if I can help it, but I can't think of a way to write an single INSERT statement to put into my trigger. Is there a way to do this without using a cursor? Any thoughts would be appreciated. David

Can I Not To Use Cursor?
I am sure I am not the first one ask this. I have got two tables, what I would like to do now is to update the second table using the values in the first table where T1.id = T2.id, normally I have to use cursor to loop through table two to achieve this. But is it possible to do this without using cursor? Thanks, Alan
