Problem With Using EXECUTE/sp_executesql
Jan 11, 2000Hi... Everybody,
I am new to using SQL Server and I present to you the following problem that I am facing:
Can I use the 'EXECUTE' or 'EXECUTE sp_executesql' in a SELECT query that assigns a value to a declared variable ?
To be more specific:
I have the following set of SQL Statements that do not seem to work:
------------------------------------------------------------------------------
DECLARE @CustomerID char(6)
DECLARE @OfficeID char(3)
DECLARE @DestinationAccountNo char(7)
DECLARE @TableName char(30)
SET @TableName = 'Users'
SET @CustomerID = '001001'
SET @OfficeID = '001'
SET @DestinationAccountNo = '0001011'
DECLARE @ExecuteString nvarchar(500)
DECLARE @CurDestPatIDChar char(2)
SET @ExecuteString = N'SELECT @CurDestPatIDChar = RTRIM(CAST(Max(CAST([UserID] AS decimal(2, 0))) AS char(2))) '
SET @ExecuteString = RTRIM(@ExecuteString) + N' FROM ' + RTRIM(@TableName)
SET @ExecuteString = RTRIM(@ExecuteString) + N' WHERE [CustID] = ''' + RTRIM(@CustomerID) + N''' AND [OfficeID] = ''' + RTRIM(@OfficeID) + N''' AND [AccNo] = ''' + RTRIM(@DestinationAccountNo) + N''''
EXECUTE SP_EXECUTESQL @ExecuteString
PRINT @CurDestPatIDChar
------------------------------------------------------------------------------
When I run this in the Query Ananlyzer I get the following error:
Server: Msg 137, Level 15, State 1, Line 0
Must declare the variable '@CurDestPatIDChar'.
The above set of statements do not seems to work with EXECUTE either.
Where as if I run the following query with the same variable declarations as above:
-----------------------------------------------------------------------------
SET @ExecuteString = N'SELECT @CurDestPatIDChar1 = RTRIM(CAST(Max(CAST([PatientID] AS decimal(2, 0))) AS char(2))) '
SET @ExecuteString = RTRIM(@ExecuteString) + N' FROM ' + RTRIM(@TableName)
SET @ExecuteString = RTRIM(@ExecuteString) + N' WHERE [CustID] = ''' + RTRIM(@CustomerID) + N''' AND [OfficeID] = ''' + RTRIM(@OfficeID) + N''' AND [AccNo] = ''' + RTRIM(@DestinationAccountNo) + N''''
EXECUTE SP_EXECUTESQL @ExecuteString, N'@CurDestPatIDChar1 char(2)', @CurDestPatIDChar1 = @CurDestPatIDChar
PRINT @CurDestPatIDChar
-----------------------------------------------------------------------------
I donot get any error messages but the variable '@CurDestPatIDChar' is not initialized.
The problem seems to be that the execute statement interprets any variable assignments (here it is '@CurDestPatIDChar', defined as part of the execute string in quotes) as local to the execute statement.
I shall be grateful if you can provide me with a solution for this,

Execute Sp_executesql And Return A Value
May 13, 2002This is what I am trying:
set @cntsql = 'select count(' + @dimky + ') as dimcnt from ' + @dimtb + ' where ' + @dimky +' is not null'
set @dimcnt = execute sp_executesql @cntsql
What I want to do is return the count from the dynamically selected database. If I type it in like:
set @dimcnt = (select count('ptky') as dimcnt from pttable where ptky is not null)
it works.... can anyone help... this code is in the middle of a cursor.

Cannot Execute DDL Sql Batach Via EXEC Or Sp_executesql ???
Mar 26, 2008Hi There
Ok i have a piece of test ddl sql that is written to a varchar(max) column. Entered by a user.
GO's and missing semi colons seem to break it, if you try to execute it with EXEC or sp_executesql, however the sql can be executed on Management Studio as is, so how can i execute it as is successfully?
In a nutshell i retreive the DDL sql from the column into a nvarchar(max) variable called @SQL , and i need to execute it.
I have tried:
EXEC(@SQL) and sp_executesql @SQL, both return the error , incorrect syntax near 'GO'.
The problem is obviously i have to have the go statements, in order to create some fo the ddl objects correctly. But EXEC and sp_executesql do not like that. I also found that semi colons are required after every statement.
The sql is as follows:
--===============================================================================
--DDL script
CREATE LOGIN TEST_LOGIN WITH PASSWORD = 'Whatever!@(!';
CREATE USER TEST_USER FROM LOGIN TEST_LOGIN;
CREATE TABLE TEST_TABLE (Column1 int NULL);
GRANT INSERT ON TEST_TABLE TO TEST_USER;
CREATE CLUSTERED INDEX TEST_INDEX ON TEST_TABLE (Column1);
GO
CREATE PROCEDURE TEST_PROCEDURES
AS
SELECT GETDATE();
GO
CREATE VIEW TEST_VIEW
AS
SELECT * FROM TEST_TABLE;
GO
--ALTER DDL
ALTER VIEW TEST_VIEW
AS
SELECT GETDATE() AS 'DATE';
GO
ALTER PROCEDURE TEST_PROCEDURES
AS
SELECT * FROM TEST_TABLE;
GO
--DROP DDL
DROP INDEX TEST_TABLE.TEST_INDEX;
DROP TABLE TEST_TABLE;
DROP VIEW TEST_VIEW;
DROP USER TEST_USER;
DROP LOGIN TEST_LOGIN;
DROP PROCEDURE TEST_PROCEDURES;

Not Able To Create Hash Table Inside Stored Proc Through Execute Sp_executesql @strQuery
Aug 21, 2007Hello,
i need to create temporary table inside SP.
i having one string variable @strQuery which contain dynamic query inside SP.
i am executing that trhough execute sp_executesql @strQuery once query build.
now instead of select query , i want to creat hash table.
so i wrote :
set @strQuery = "Select * into #tmp_tbl from table_name..."
when i tried to execute it through
execute sp_executesql @strQuery , its giving error 'Invalid object name '#tmp_tbl'
If i removed Hash then it works fine. even for double Hash also its work fine.
but i want hash table only as i want that table local to that user.
Even direct execution of select statement without @strQuery works fine. but i want to execute @strQuery through execute sp_executesql @strQuery only as query is dynamic .
please guide me how to do this?
its very urgent for me.
thanks in advance.
Exec Sp_executesql Vs. Sp_executesql And Performance
Jul 23, 2005This 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?

Jul 31, 2006I 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.

Aug 8, 2005What 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 ..
Thanks.
Sp_executesql ¿qué?
Feb 27, 2008I'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.

Sp_executesql

I am trying to execute sp_executesql dynamically. What I am trying to do is read all the user tables using a cursor build sql statement and using

OPEN c1
FETCH NEXT FROM C1 INTO @v_TableName

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?

Oct 2, 2006Hi 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

Sp_executesql For Dummies
Jul 5, 2006I 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.

I Can't Use Sp_executesql Within Functions
Apr 9, 2007Hi 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.

Question About Sp_executesql
May 28, 2008I'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.
