Activating Dynamic Sql Whereby Sp_executesql
Apr 2, 2008
Hi everyone,
The following code to run dynamic sql:
DECLARE @params NVARCHAR(4000)
DECLARE @portion INT
SET @portion=6
DECLARE @mydynamic NVARCHAR(4000)
SELECT @mydynamic = ' SELECT TOP @portion * FROM server.databse.dbo.table'
SELECT @params = N'@portion INT '
EXEC sp_executesql @mydynamic,@params, @portion
yields the following error message:
Msg 102, Level 15, State 1, Line 1
Incorrect syntax near '@portion'.
anyone has any idea why ? How it should be corrected?
Thanks

Here is the query..
@ENTITY, @ FIELD, @KEYID, @VALUE comes dynamically using cursor. Here in this example I have took one sample and assigned it a value to do sanity check.
DECLARE @ENTITY nvarchar (100)
SET @ENTITY ='AccidentDimension'
DECLARE @FIELD nvarchar (100)
SET @FIELD = 'UHReceivedDate'
DECLARE @KEYID nvarchar (100)
SET @KEYID = '1074958'
DECLARE @VALUE varchar (100)
SET @VALUE = '10JAN2020'
DECLARE @FLAG NVARCHAR(50);
SET @FLAG = (SELECT LEFT(@ENTITY, (SELECT CHARINDEX( 'DIM', @ENTITY) -1)) )+ 'LastUpdateFlag';
DECLARE @KeyName NVARCHAR(50);
SET @KeyName = (SELECT LEFT(@ENTITY, (SELECT CHARINDEX( 'DIM', @ENTITY) -1)) )+ 'Key'
DECLARE @KeyValue INT
DECLARE @SQL1 NVARCHAR (1000)
SET @SQL1 = ' SET @KeyValueOUT = Select '+ @KeyName + ' FROM ClaimManagementFact WHERE ClaimKey = ' + @KEYID +
' GROUP BY ' + @KeyName + ' HAVING SUM(TotalClaimCount) > 0 OR SUM(IncidentOnlyClaimCount) > 0 )'
EXECUTE sp_executesql @SQL1, @KeyValueOUT INT OUTPUT;
@KeyValue= @KeyValueOUT OUTPUT;
Select @KeyValue
A) What i want to do is store the value resulting from select statemenet by executing @SQL1 which is INT to @KeyValue. In previous thread I tried various thing but resulting in errors.
Thanks in advance for help

Hi there,
I am trying to build a proc that uses a loop to import data into several tables. The data is copied into the appropriate table according to the contents of the variable @PracticeCode. I am also trying to add a date value to each record as it is added to the table. I thought that the best way to do this would be t use the sp_executesql stored proc. but I am having difficulty getting it to work. Here's what I have done so far:
-- insert data into proper tables with extract date added
SET @SQLString ='INSERT INTO GMS_48hrAccess.dbo.tbl_Surgery'+@PracticeCode+' SELECT
SurgeryKey,'+
@extractDate+',
ClinicianCode,
StartTime,
SessionGroup,
[Description],
SurgeryName,
Deleted,
PremisesKey
FROM GMS_48hrAccess.dbo.tbl_SurgeryIn'
EXEC master..sp_executesql @SQLString
And here's the error message that I get:
Server: Msg 241, Level 16, State 1, Line 90
Syntax error converting datetime from character string.
I understand why I am getting this error I just can't seem to fix it. I've consulted BOl and have tried various Parameter combinations but to no avail.
Can anyone help?
Thanks

For the example stored procedure below, lets say I want to use the "sp_executesql" stored procedure instead of "EXECUTE".
CREATE PROCEDURE [dbo].[spGetEmployees]
@managerId int,
@employeeIdList nvarchar( 200 )
AS
EXECUTE
(
'SELECT *
FROM [dbo].[hrEmployees]
WHERE [ManagerID] = ' + CAST( @managerId AS nvarchar ) + '
AND [EmployeeID] IN (' + @employeeIdList + ')'
)
I want to rewrite it something like this. Please see MSDN documentation ( http://msdn2.microsoft.com/en-us/library/ms188001.aspx ) for sp_executesql stored procedure usage.DECLARE @selectStatement nvarchar(500)
SET @selectStatement = 'SELECT * FROM [dbo].[hrEmployees] WHERE [ManagerID] = @paramManagerID AND [EmployeeID] IN (' + @employeeIdList + ')'
DECLARE @paramList nvarchar(500)
SET @paramList = '@paramManagerID int'
EXECUTE sp_executesql @selectStatement, @paramList, @paramManagerID = @managerId
Reason for using "sp_executesql" is the performance gain.However, as you can see, the @employeeIdList cannot be included as part of the Parameter List ( @paramList )like the @managerId since it **has** to be passed in as a varchar ( example: @employeeIdList = '1,2,3,4' ).
My Question Is there a way to include it as a parameter instead of it being part of the embedded dynamic SQL syntax?

Okay, so I came across an odd performance issue that I'm wondering if some guru can help me out with.
I have a query that uses a paging algorithm that uses a paging algorithm and a table variable, then gets a page of data based on a join to that table variable. Here's a simplified query using the algoritm:
--declare table variable... not shown for brevity
--make sure we only store the least amount of records possible
SET ROWCOUNT ( @pageNumber + 1 ) * @pageSize
--insert into table variable
INSERT INTO @TableVariable( Key )
SELECT key FROM table
WHERE whatever = @p1
--we only want one page of data
SET ROWCOUNT @pageSize
--now get the page of data from the table
SELECT key FROM table
WHERE whatever = @p1
AND [TableVar Identity Column] > @pageNumber * @pageSize
The algorithm works great for our needs, BUT, I noticed something a little odd about its behavior during performance testing.
In particular, when I run the query using Sql Server Management Studio, where I manually DECLARE all the variables it ends up needing only 156 reads to complete the job. When I call it from the app using ADO.NET, however, I noticed it needs 310 reads! Huh?
I looked for differences, and the only one I could determine was that ADO.NET passes the query and uses sp_executesql and passes the parameters vs. declaring and setting them statically before executing the query. I confirmed that this was the issue by manually running sp_execute SQL and seeing that it took roughly the same number of reads (274) to process the query.
Naturally, I don't want the time it takes to perfrom my query to double, but and frankly I don't understand why there would be a difference in performance. Can anyone help me track down what is going on and suggest to me how to fix the problem.
I assume that SQL Server Management Studio optimizes the execution path somehow, but I'm not sure how to gain the same benefit for my passed query. Can I enable something with hints? Is there something else going on that I should know about?

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?

Hi all,
On SQL Server 7 SP4.
3 tables with about 100 000 rows each one, frequently updated.
1 clustered index on primary key, and 2 non clustered index on columns used by JOIN and by queries.
Fillfactor for index : 90.
PAD_INDEX : not activated.
I have some deadlocks problems, probably due to index pages and key locking (as precised in error log). Is it possible that the cause of that is splitting index pages while UPDATE ?
May I activate PAD_INDEX to solve part of this problem ?
Thanks for any help

Hi,
I have created Queue with the following syntax. But it is not getting activated itself. What I have to do to get it activated itself, and what could be the frequency by default.
CREATE QUEUE NewCustomerQueue
WITH ACTIVATION
(PROCEDURE_NAME = prProcessNewCustomers,
STATUS = ON,
MAX_QUEUE_READERS = 1,
EXECUTE AS SELF)
GO
If I execute the prProcessNewCustomers procedure manually it is showing that the Queue has been activated. What change I have to make in the syntax to get it activated itself.
Actually I have two scenarios in my requirement,
1. One Queue processing immediately when it receives data (Order Processing)
2. Another Queue, Process when the server is idle i.e., off-peak time (for mailing)
What syntax I have to use for these.
Please help.
Thanks in advance

Hi
I am new to SQL / SQL Server and have downloaded SQL Server 2005 Express.
I also appear to have an existing SQL Server program on my PC which includes Query Analyzer. I wish to use Query Analyzer. Is this compatible with SQL Express?
When I try to open Query Analyzer using Windows Authentication I get the error msg:
'Unable to connect to server HOME-DHGV3DIC8N:
Server: msg 17, level 16, state 1
[Microsoft] [ODBC SQL Server Driver] [Shared memory] SQL Server does not exist or access denied.'
I am guessing that I need to create some sort of server which I can use to run SQL server.
Could anyone let me know how I do this? And also if I will be able to run Query analyzer on SQL Express edition.
I'd be really greatful
Regards

Hi,
I am having an SQL CLR stored proc which looks like this in SQL Svr
CREATE PROCEDURE [dbo].[callspGetMessage]

When I am trying to alter the queue to attach to this procedure using following code
alter queue q1 with activation (
status = on,
max_queue_readers = 1,
procedure_name = [callspGetMessage],
execute as owner);
I am getting following error.
The signature of activation stored procedure 'callspGetMessage' is invalid. Parameters are not allowed.
Parameters to the stored proc are not allowed or am I doing anything wrong.
Any help is greatly appreciated.
Thanks,

Developing a desktop application which calls a local instance of ".sqlexpress".
This app needs to set data base options and add/del various table columns.
When activating the application role, I get the following message:

Anyone know what this message means?
I have searched SQL Server Books On-Line and been unable to find a list of Sql err numbers. Either I have missed the obvious or Books On-Line has missed the obvious.

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 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

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 have this code:
USE BDPrincipal
GO
IF OBJECT_ID(N'aquery') is not null
DROP FUNCTION aquery
GO
CREATE FUNCTION aquery()
Returns nvarchar(500)
as
Begin
Declare @var nvarchar(500);
Set @var = 'Select Distinct Description from dbo.tblScanners';
Return @var
end
GO
exec sp_executesql aquery;
I created that code to prove if it works.
But the result doesn´t appear, and the message is:
Command(s) completed successfully.
I need it to work.
Because I need to create a very dinamic query.
Please help me!
