I have a situation where the SQL for my cursor MUST be assembled in a buffer, but I cannot get the cursor declaration to accept my buffer as the SQL statement.
these attempts did not work:
DECLARE crsCursor CURSOR FOR @vchrSQL
DECLARE crsCursor CURSOR FOR (@vchrSQL)
Does anybody know if you definitely can or definitely cannot use dynamic SQL with cursors?
Hi,is it possible to create a cursor from a dynamic string?Like:DECLARE @cursor nvarchar(1000)SET @cursor = N'SELECT product.product_idFROM product WHERE fund_amt > 0'DECLARE ic_uv_cursor CURSOR FOR @cursorinstead of using this--SELECT product.product_id--FROM product WHERE fund_amt > 0 -- AND mpc_product.status= 'aktiv'Havn't found anything in the net...Thanks,Peppi
Is there any way to create a cursor, based on a dynamically created select_statement? Something like: DECLARE someCRS CURSOR LOCAL FAST_FORWARD FOR @strSelect where @strSelect is previously declared as let's say varchar. I don't want to create a stored procedure for this.
select name from sys.databases where name like 'Property%' and name <> 'PropertyCenter'
open dbname_name
fetch next from dbname_name
into @dbname
WHILE @@FETCH_STATUS = 0
BEGIN
set @sql =
'
select p.sa_property_id, z.zipcode as sa_site_zip, z.state as sa_site_state, z.city as sa_site_city, z.county as sa_site_county,@dbname ,(select @@servername) as servername, county'+@countyname+'
from zipcodes z join tbl_reply_assr_final p on z.zipcode = p.sa_site_zip'
I am trying to decalare the cursor in the below stored procedure. Can any one please help me to correct the cursor declaration?? Basically, i am testing how to declare the cursor in stored procedure.
CREATE PROCEDURE STP_EMPSAL @empno int, @Employee_Cursor CURSOR VARYING OUTPUT FOR SELECT empno FROM AdventureworksDW.dbo.emp AS OPEN Employee_Cursor; FETCH NEXT FROM Employee_Cursor into @empno; WHILE @@FETCH_STATUS = 0 BEGIN BEGIN TRAN UPDATE emp set sal= sal+ 2000 where empno = @empno and comm is null mgr='Scott'; FETCH NEXT FROM Employee_Cursor into @empno; COMMIT; END; CLOSE Employee_Cursor; DEALLOCATE Employee_Cursor;
I am using SQL 2005 and i would like to create a cursor from executing a stored procedure (dbo.SP_getDate @Variable). Something like this:
DECLARE Cursor1 CURSOR FOR EXECUTE dbo.SP_getDate @Variable
i get an error saying "incorrect syntax near the keyword 'EXECUTE'." cannot get rid of the error. what am i doing wrong? (i am trying to avoid using #tempTbl to store the results of the execute first and then doing a select on the #tempTbl)
Not sure if i am doing this right all together. any help would be greatly appreciate.

The @Table_Name variable is declared, If I replace the delete statement (DELETE FROM @Table_Name ) with (PRINT @table_name) it works and print the table names.
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
The stored procedure, below, results in this error when I try to compile...
Msg 156, Level 15, State 1, Procedure InsertImportedReportData, Line 69 Incorrect syntax near the keyword 'ORDER'.
However the select statement itself runs perfectly well as a query, no errors.
The T-SQL manual says you can't use the keywords COMPUTE, COMPUTE BY, FOR BROWSE, and INTO in a cursor select statement, but nothing about plain old ORDER BYs.
What gives with this?
Thanks in advance R.

i have been asked about a thing that, i think, is not possible. But maybe i am wrong.
question: Is it possible to have a Stored Procedure in that the declaration of the variables is dynamic? This means, can i get the variable name and the type of it from a database to create a dynamic stored procedure that changes itself by firing a trigger.
Thanks for all oppinions and answers. everWantedLINUX
I created an updateable partioned view of a very large table. Now I get an error when I attempt to declare a CURSOR that SELECTs from the view, and a FOR UPDATE argument is in the declaration.
There error generated is:
Server: Msg 16957, Level 16, State 4, Line 3
FOR UPDATE cannot be specified on a READ ONLY cursor
Here is the cursor declaration:
declare some_cursor CURSOR
for
select *
from part_view
FOR UPDATE
Any ideas, guys? Thanks in advance for knocking your head against this one.
PS: Since I tested the updateability of the view there are no issues with primary keys, uniqueness, or indexes missing. Also, unfortunately, the dreaded cursor is requried, so set based alternatives are not an option - it's from within Peoplesoft.
I've looked up Books Online on Dynamic Cursor/ Dynamic SQL Statement.
Using the examples given in Books Online returns compilation errors. See below.
Does anyone know how to use Dynamic Cursor/ Dynamic SQL Statement?

I need to pass a list of values into a cursor as such...
DECLARE @group_SQL varchar(255)
SET @group_SQL = 'SELECT group_id FROM groups where group_id in (' + @group_id + ')'
DECLARE groupContact_import_cursor CURSOR FOR EXEC(@group_SQL) OPEN groupContact_import_cursor FETCH NEXT FROM groupContact_import_cursor INTO @group_id WHILE (@@FETCH_STATUS = 0) BEGIN insert into groupContacts (group_id, contact_id) values (@group_id, @new_cid) FETCH NEXT FROM groupContact_import_cursor INTO @group_id END CLOSE groupContact_import_cursor DEALLOCATE groupContact_import_cursor
But MS SQL doesn't seem to like the FOR EXEC(@group_SQL). Can someone shed some light?
I am trying to use a dynamic cursor in a stored procedure: The code looks like this :
/************************************************** *** set @sFormula = 'Monthlyformula' set @sStartDate = '02/01/2004' set @sEndDate = '02/01/2004'
exec('DECLARE APPGRIDROWS_METRICS CURSOR FOR select populateid From appgridrows where histdisplaygrid = 3 And '+ @sFormula +' Is Null and exists (SELECT 1 From PAYROLL_DATA_PERIOD as h Where h.id=1 and h.populateid=appgridrows.populateid and h.StartDate between '+ @sStartDate +' and '+ @sEndDate +')' ) /************************************************** ***
And this is what it is interpreting
select populateid From appgridrows where histdisplaygrid = 3 And Monthlyformula Is Null and exists (SELECT 1 From PAYROLL_DATA_PERIOD as h Where h.id=1 and h.populateid=appgridrows.populateid and h.StartDate between 02/01/2004 and 02/01/2004)
My problem is Is there anyway that I can put the quotes before those dates('02/01/2004') so that my cursor has some records returned
I am trying to do dynamic Select for Cursor.

Help please,Have a situation when converting from Oracle SP's to SQL SP's. The oldoracle cursor was roughly as followsCURSOR cur_rsStock ISselect*from(select StockRowId, CategoryIdfromSTOCKDISPOSABLEwhereSTOCKDEFID=numDefIdORDER BYSTOCKROWID)whereROWNUM <= numQuantity;The closest I can get in MS SQL is as follows :declare cur_rsStockCURSOR forselect top @numQuantityStockRowId, CategoryIdfromSTOCKDISPOSABLEwhereSTOCKDEFID=numDefIdORDER BYSTOCKROWIDBut, SQL doesn't allow variables next to top. I know I can assign the wholeselect statement to a string and use exec to exec the string to get arecordset but how can I point a cursor to receive its output?i.e.set @strSQl = select top ' + @numQuantity + ' StockRowId, CategoryId.......exec @strSQLbut how do I dodeclare cur_rsStockset cur_rsStock = ( exec @strSQL)Flapper

i read in the SET ROWCOUNT documentation URL.... that 'The ROWCOUNT option does not affect dynamic cursors', it does affect my dynamic cursor created in a table function which looks like this :
CREATE FUNCTION MyTableFunction()Â RETURNS @MyTable TABLE (MYFIELD INTEGER) AS BEGIN Â DECLARE @xxx INTEGER Â DECLARE My_Cursor CURSOR DYNAMIC FOR Â [code]...
I would like the number of rows retruned by MyTableFunction limited to 2, but NOT the inside proc cursor's select !Set Rowcount 0 is forbidden in table function. I cannot use TOP in select * from MyTableFunction instead of setting ROWCOUNT to 2. I'm using SQL Server 2008 or 2012.
Hi, In a stored procedure (SP1) I call another stored procedure (SP2), passing along parameters. In SP2 I dynamically build cursor c1. I can execute SP2 without any problems but when I start SP1 I get the following message:
Msg 16916, Level 16, State 1, Procedure SP2, Line 114 A cursor with the name 'C1' does not exist.
Yes, the cursor is of type GLOBAL. I am sure I miss something here ... Any help is highly appreciated !
I am stuck in a bit of a conundrum for quite a while now, and I hope someone here will help me figure this one out.
So, first things first: let me explain what I need to do. I am designing a web application that will allow users to consult info available in a SQL2000 database. The user will enter the search criterea, and hopefully the web page will show matching results.
The problem is the results shown aren't available per se in the DB, I need to process the data a bit. I decided to do so on the SQL Server side, though the use of cursors. So, when a user defines his search criteria, I run a stored procedure that begins by building a dynamic sql query and creating a cursor for it. I used a global cursor in order to do so. It looked something like this:
SET @sqlQuery = ... (build the dinamic sql query)
SET @cursorQuery = 'DECLARE myCursor CURSOR GLOBAL FAST_FORWARD FOR ' + @sqlQuery
EXEC @cursorQuery
OPEN myCursor
FETCH NEXT FROM myCursor INTO ...
CLOSE myCursor
DEALLOCATE myCursor
This works fine, if there's only one instance of the stored procedure running at a time. Should another user connect to the site and run a search while someone's at it, it'll fail due to the atempt to create a cursor with the same name.
My first thought was to make the cursor name unique, which led me to:
...
SET @cursorName = 'myCursor' + @uniqueUserID
SET @cursorQuery = 'DECLARE '+ @cursorName + 'CURSOR FAST_FORWARD FOR ' + @sqlQuery
EXEC @cursorQuery
...
The problem with this is that I can't do a FETCH NEXT FROM @cursorName since @cursorName is a char variable holding the cursor name, and not a cursor variable. So to enforce this unique name method the only option I have is to keep creating dynamic sql queries and exucting them. And this makes the sp a bitch to develop and maintain, and I'm guessing it doesn't make it very performant.
So I moved on to my second idea: local cursor variables. The problem with this is that if I create a local cursor variable by executing a dynamic query, I can't extract it from the EXEC (or sp_executesql) context, as it offers no output variable.
I guess my concrete questions are:
Is it possible to execute a dynamic sql query and extract a (cursor) variable from it?Is it possible to populate a local cursor variable with a global cursor, by providing the global cursor's name?Can I create a local cursor variable for a dynamic sql query? How?
Anybody sees another way arround this?Thanks in advance,
I need to find all uses of special characters in a database. I used the following code to do this:
USE dbName GO IF OBJECT_ID('tempdb.dbo.#Results') IS NOT NULL DROP TABLE #Results GO
[code]...
This will check all tables in the database, but if you want to check specific tables you can uncomment the line in the where clause and specify tables to be checked. The query will return any text fields that have any characters other than letters, numbers or spaces.
This code works fine for me because all the tables in my database have single column primary keys. However I know how much Jeff Moden hates cursors or RBAR queries, so my question is could this have been done by any method other than using a cursor?
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.
