Using Sp_executesql In Cursor
Aug 2, 2007
hi,
I try to use a sql statmenttext as varaible in cursor function with sp_executesql or sp_execsql.
But these Stored Procedures can't use in cursor function.
Q : How can I use a sql statmenttext in corsur funtion as using sp_executesql or sp_execsql ?
Sample Code :
declare @sql nvarchar(500)
declare @table nvarchar(50)
declare @Field1 nvarchar(50)
declare @Field2 nvarchar(50)
declare @FieldValue nvarchar(50)
set @table = 'dbo.kisi_bilgileri'
set @Field1 = 'TcKimlikNo'
set @Field2 = 'KisiNo1'
set @Fieldvalue = '9000050715'
set @sql = 'select ' +@Field1+ ', ' + @Field2+ ' from ' +@table + ' where ' +@Field1+ ' = ' +@Fieldvalue
declare TabloOku cursor for
execute sp_sqlexec @sql -- isn't work, what can I use instead of ?
open TabloOku
fetch next from TabloOku into @Tablo
WHILE @@FETCH_STATUS = 0
begin ...

This is a odd problem where a bad plan was chosen again and again, butthen not.Using the profiler, I identified an application-issued statement thatperformed poorly. It took this form:exec sp_executesql N'SELECT col1, col2 FROM t1 WHERE (t2= @Parm1)',N'@Parm1 int', @Parm1 = 8609t2 is a foreign key column, and is indexed.I took the statement into query analyzer and executed it there. Thequery plan showed that it was doing a scan of the primary key index,which is clustered. That's a bad choice.I then fiddled with it to see what would result in a good plan.1) I changed it to hard code the query value (but with the parmdefinition still in place. )It performed well, using the correct index.Here's how it looked.exec sp_executesql N'SELECT cbord.cbo1013p_AZItemElement.AZEl_Intid AS[Oid], cbord.cbo1013p_AZItemElement.incomplete_flag AS [IsIncomplete],cbord.cbo1013p_AZItemElement.traceflag AS [IsTraceAmount],cbord.cbo1013p_AZItemElement.standardqty AS [StandardAmount],cbord.cbo1013p_AZItemElement.Uitem_intid AS [NutritionItemOid],cbord.cbo1013p_AZItemElement.AZeldef_intid AS [AnalysisElementOid] FROMcbord.cbo1013p_AZItemElement WHERE (Uitem_intid= 8609)', N'@Parm1 int',@Parm1 = 8609After doing this, re-executing the original form still gave badresults.2) I restored the use of the parm, but removed the 'exec' from thestart.It performed well.After that (surprise!) it also performed well in the original form.What's going on here?

In MSDN file I read about static 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
Â
             while @@FETCH_STATUS=0
              fetch from ll
               update ag set salary=200 where 1=1
Â
  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.

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 have been trying to get my dynamic query to work with sp_executesql and I cant seem to figure out this one issue.DECLARE @SQL NVARCHAR(1000)SET @SQL = N'WITH Data AS(SELECT Id, Username, FirstName, LastName, Email, LastLogin, ROW_NUMBER() OVER(ORDER BY @SortExpression) AS RowNumber FROM Users) SELECT * FROM Data WHERE RowNumber BETWEEN @Between1 AND @Between2'EXECUTE sp_executesql @SQL, N'@SortExpression VARCHAR(50), @Between1 INT, @Between2 INT', @SortExpression = 'Email', @Between1 = 1, @Between2 = 10As you can see, the data should get sorted by the value of @SortExpression. However thats not the case. The Data does not get sorted at all no matter that i pass in as the value of @SortExpression.I can't seem to figure out why its not working.

What is wrong in this query..how can I make it to work
DECLARE @strSQL nVarchar(4000)
DECLARE @Name VArchar(100)
--SET @Name = '''sysdatabase'',''sysindexes'''
SET @Name = ''sysdatabase''
SET @strSQL = 'SELECT * FROM dbo.sysobjects WITH (NOLOCK) WHERE Name IN (@prmName)'
EXECUTE dbo.sp_executesql @strSQL,
N'@prmName varchar(100)',
@prmName= @Name
Note : I do not want to replace the query as
SET @strSQL = 'SELECT * FROM dbo.sysobjects WITH (NOLOCK)
WHERE Name IN ' + @Name + ')' , because my queryplan changes if I do this.
Any work around or anything you guys suggest ..

I'm having trouble working out why the sp_executesql procedure is not replacing my place holders with the value assigned to it.
Some quick info: I'm running the routine from the commandline through OSQL on a box that has MSSQL2000 enterprise installed. The code is sent to a MSSQL2005 box.
I've noticed one dumb thing I've done and that is making the nvarchar variable @db_name a different size to the one declared in the sp_executesql command. But I'm not sure if that is the problem. It throws a @db_name is not a database error etc.
Snippet that is not working:
declare @db_name varchar(80)
declare @sql_command nvarchar(1500)-- for our dynamic sql command within the cursor loop.

Is there anything that will allow you to execute a line of sql code if it is longer than 4000 Unicode characters? The line of code is stored in a NVARCHAR Variable.
I'm using sp_ExecuteSQL and have hit the 4000 character wall

I have a string which I want to pass into an IF statement. Here's what I have:
declare @sumclause varchar(4000)
set @sumclause = '(select count(*) from Participants where Weeks_Left<=8 or CDE_ACTV=''24'''
IF cast(@sumclause as int)>0
BEGIN
...
END
I'm first putting it in a string because I'm passing another string into it which can't be seen above.
As you can see, I tried casting it since it had a problem with computing a string as an int, but it still doesn't work. Help?

Hi There
Is a table variable invalid for sp_executesql ?
I am trying the following:
SELECT @SQL = N'WAITFOR
(RECEIVE message_body, conversation_handle, message_type_name, message_sequence_number, conversation_group_id FROM ' + @callingQueue + ' INTO @msgTable WHERE conversation_group_id = '
+ CAST(@conversationGroup AS char) + '), TIMEOUT 2000'
EXEC sp_executesql @SQL, N'@msgTable TABLE output', @msgTable out
I get the following message:
Msg 137, Level 15, State 2, Procedure CENTRAL_Queue_Processor, Line 92
Must declare the scalar variable "@msgTable".
I have decalred the variable but it is a table variable, this leadds me to believe sp_execute sql only supports scalar varibles not table variables, BOL does not say yes or no in this respect.
Can this be done?
Thanx

Hello,
I am using sp_executesql this to pass parameter to sql string and I am seeing deadlock between sp_prepexec which does UPDATE with another UPDATE done by another process. When it comes to speed and deadlock, would you recomand not using sp_executesql?

In out web application it happens very rarely that same query gets executed more than once meaning that sp_executesql is degrading performance. Does anyone know a way to tell ADO.NET to stop encapsulating queries in sp_executesql? Thank you.

Hi all, I just wanted to know why this doesn't work: if @1's values is computer---------------------------------------------------------------------------------------------------------- BEGIN FETCH NEXT FROM keyword_cursor into @1

SELECT @paramlist = '@x1 nvarchar(200)' print @sql EXEC sp_executesql @sql, @paramlist, @1
RETURN 0 ENDThe @sql string evaluates to:select title, notes from pubs..titles where title LIKE '%'+ @x1 + '%' OR notes like '%' + @x1 + '%'---------------------------------------------------------------------------------------------------------------I just don't get it ?? Doesn't sp_executesql just replaces the @x1 with @1?

I have a stored procedure using dynamic SQL and I've been told I can no longer use 'exec (@strsql)' and have to use sp_executesql instead.
Fiiiiiiine...except I don't know how to use it and make it work with the parameter I'm passing in.
The original sproc that I have to change reads as:
CREATE PROCEDURE dbo.sp_LetsGetSomeData(@Filter nvarchar(200) = NULL)
AS
DECLARE @strSQL nvarchar(200)
IF @Filter IS NOT NULL
BEGIN
SET @strSQL = N'SELECT * FROM vwRandomViewName ' + @Filter
END
IF @Filter IS NULL
BEGIN
SET @strSQL = N'SELECT * FROM vwRandomViewName'
END
EXEC(@strSQL)
GO
And is called thusly:
EXEC sp_LetsGetSomeData @Filter = ' WHERE Team = ''RandomTeam'''
When I do this it never adds the filter. I tried to write a sproc like this:
CREATE PROC dbo.LetsGetSomeData2(@Filter nvarchar(200) = NULL)
AS
DECLARE @strSQL nvarchar(200)
SET @strSQL = N'SELECT * FROM vwRandomView'
EXECUTE sp_executesql @strSQL, @Filter
GO
and call it the same way as the original flavor sproc, it's as if I'm asking it to just select all from vwRandomView.
I know I'm doing something massively wrong but I'm just having a brain-dead day and can't make sense of the books online.

Hi all
i have Function and in the context of this function i need to build a Dynamic Query String according to input parameters and execute it with sp_executesql. BUT until now i didn't know that SQL doesn't allow to have Exec command within a function,am i right?
Apparently this is true because for example create the following Function..
Create Function Test(@Input int)
Returns int
AS
Begin
Exec sp_who -- only for Test purpose
Return @Input
End
Now Execute this --> Select dbo.test(12).....
Sql Server will return the following Error
Server: Msg 557, Level 16, State 2, Procedure Test, Line 6
Only functions and extended stored procedures can be executed from within a function.
Could Any one help me? i need function with dynamic Sql execution because i can only use function in SELECT statements !!!
Any help greatly would be appreciated.
Kind Regards.

I'm not very familiar with Dynamic SQL, so you may find this question dumb. Sorry if this is the case ;-)
I've been reading Raul Garcia's blog about SQL injection and I would like to be able to do something like this:
DECLARE @tab varchar(50)
SET @tab = 'aTableName'
DECLARE @sql nvarchar(200)
DECLARE @param_def nvarchar(100)
DECLARE @p_tab varchar(50)
SET @sql = N'SELECT * FROM @p_tab;'
SET @param_def = N'@p_tab varchar(50)'
EXECUTE sp_executesql @sql, @param_def, @p_tab=@tab;
instead of
SET @sql = N'SELECT * FROM' + @tab
directly.
But this does not work in a Stored Proc. with SQL Server 2005. My question is : how to do it ?
Thanks for reading me.

Hi All,
The following is cut from SQL profiler, database is SQL 2000 SP4. Query 1 takes almost zero time and 26 reads. Query 2 takes 16 millsecs and 2862 reads and the only difference is that Query2 has parameters. I have run the query's multiple times and in different order and the results are the same. My reading of the documentation says that Query 2 should be faster due to not having to recreate the execution plan. If the execution plan is a bad one and is cached how do I remove it. Is there anyway to force a recompile or am I know in stored procedure territory.
Can anyone give me an explanation as it looks like we should be changing our code to use literal's where ever possible rather than parameter substitution.
TIA
