I have a full sql statement which was generated dynamicly, and need to
execute that string and then take the output and generate a
spreadsheet document based on the output. I'm new to sql and the book
I have doesn't really explain much. Anyone with an example of their
work would be appreaciated.
thank you.
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?
View 3 Replies View RelatedI 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.

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.

hi everybody
How can we execute a string of sql statements in Oracle ,similar to sp_executesql in sql server.
ie a string can contain insert into a table statement,delete a row from a table statement, update etc.
Thanks all of You
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?

Is a table variable invalid for sp_executesql ?
I am trying the following:
SELECT @SQL = N'WAITFOR

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.

set @a = 'select top 1 '+@camp+' from paracnet where datacalc = ''1/1/2005'''
exec sp_executesql @a
How can I store the value returned by the exec sp_executesql statement into a variable?
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!
I have not used this sp. We have a dynamic SQL statement generated by a sp.For performance reasons I would like to use it to reduce the number ofexplain plans created. I would like to understand its usage and pitfalls(if any) to its use. Any comments from the user community?

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

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?
I am attempting to create dynamic SQL with sp_executesql.
However, it seems that parameters can't be created arbitrarily in the query string. In particular, the name of the table apparently can't be parametrized, or I am doing something wrong.
I use SQL Server 2000 with the latest service pack.
The table task has a few columns of which TaskID is Primary Key and INT.
This works fine:
DECLARE @pot nvarchar(200)
SET @pot = 1
DECLARE @pot2 nvarchar(200)
SET @pot2 = 'task'
EXEC sp_executesql N'SELECT * FROM task WHERE TaskID = @pot', N'@pot varchar(128), @pot2 varchar(128)', @pot, @pot2
However, this does not work:
DECLARE @pot nvarchar(200)
SET @pot = 1
DECLARE @pot2 nvarchar(200)
SET @pot2 = 'task'
EXEC sp_executesql N'SELECT * FROM @pot2 WHERE TaskID = @pot', N'@pot varchar(128), @pot2 varchar(128)', @pot, @pot2
Note that the only change in the second case here is to pass the same table name as a parameter.
The error message is: Must declare the variable '@pot2'.
However, @pot2 is clearly declared already!
1. Is there any way to parametrize the table name as above?
2. Is there any general guideline on what in the query can be parametrized?
Note: I know that I could parametrize the table name by concatenating the first parameter of sp_executesql but that would assume my question (1) was answered 'no' already.
Thankful for any advice.
Hi,

+ Case @DaysDiff When 0 Then N'' Else N' and DATEDIFF(d,@BillingDate , InvoiceDate) <= @DaysDiff ' End
+ Case @MatchName When 1 Then N' and Left(Name,@CharsToMatch) = Left(@PassengerName, @CharsToMatch) ' Else N'' End ;
SET @ParmDefinition = N'@BillingAmount decimal, @TicketNumber varchar(15), @RemoveRight tinyint, @RemoveLeft tinyint, @BillingDate datetime, @DaysDiff tinyint, @CharsToMatch tinyint, @PassengerName varchar(35), @Passenger_OUT varchar(35) OUTPUT, @Ticket_OUT varchar(15) OUTPUT, @TAN_OUT varchar(25) OUTPUT';
EXECUTE sp_executesql @SQLString, @ParmDefinition,@BillingAmount=@BillingAmount, @TicketNumber=@TicketNumber, @RemoveRight=@RemoveRight, @RemoveLeft=@RemoveLeft, @BillingDate=@BillingDate, @DaysDiff=@DaysDiff , @CharsToMatch=@CharsToMatch, @PassengerName=@PassengerName, @Passenger_OUT=@Passenger_new OUTPUT, @Ticket_OUT=@Ticket_new OUTPUT, @TAN_OUT=@TAN_new OUTPUT;
Print @SQLString will gives the statement with variables and I need to see the actual data plugged in during runtime.
If I take the ouput of @SQLString and run it myself by adding variables it works fine
Thanks

I am trying to get file space usage information for all of the databases in my server and store it in a table to collect a history of spce usage. I know that I can get this on a per database basis if I use DBCC(SHOWFILESTATS). So, I would issue a USE statement and then a DBCC statement inserting the rows into a temp table for later processing. Since databases can come and go, I would like to loop through the records in sysdatabases and for each one, issue the USE and then the DBCC via an sp_executesql.
This is all working fine except, the sp_executesql of the USE statement seems to be ignored.
Is there some way to get this statement to take effect?
Is there a better way to get this information - ie is this stored in a table or view that I can't seem to find?
Thanks in advance for your help.

it is possible to do this?
DECLARE @SQLString nvarchar(500);
DECLARE @CharVariable nvarchar(500);
SET @CharVariable = 'column_name';
Set @SQLString=
N'update dbo.table_name set dbo.table_name.@column_name=value';
EXECUTE sp_executesql @SqlString,
N'@column_name nvarchar(500)',
@column_name = @CharVariable;
I want to change column name.
If i exchange dbo.table_name.@column_name=value' to dbo.table_name.column_name=@value' all works fine.
So maybe imbossible to change in that way? I mean sp_executesql only work when i need set value not table or column names?
