I am trying to use dynamic sql with a return parameter, but with limited success. I am using WebMatrix, vb.net and MSDE to perform this routine. Can someone please clue me in. I have read two fine articles by <a href='http://www.algonet.se/~sommar/dyn-search.html>Erland Sommarskog</a> on dynamic sql using sp_executesql, as well as the somewhat opaque article by Microsoft (262499) on the subject.
While there may be other ways to accomplish this task, I am interested in making it work with dynamic SQL. In production, there will be over 20 parameters coming from the vb.net to the SQL, being driven from user input. Then those same variables will be used to actually retrieve the records to a datagrid.
So with a tip of the cap to Rod Serling, I submit this small code and SQL for your consideration from my Twilight Zone:
Public Function totalrecordsbysql(list as arraylist) as integer dim RetVal as new integer dim querystring as string
Dim cn As SqlConnection = New SqlConnection(ConfigurationSettings.AppSettings("Indiafriend")) Dim cmd As SqlCommand = New SqlCommand("SimpleDynProfileCount", cn) cmd.commandtype = commandtype.storedprocedure
try mydr=cmd.executereader() catch e as sqlexception dim err as sqlerror dim strErrorString as string
for each err in e.Errors strErrorString += "SqlError: #" & err.Number.ToString () & vbCRLF + err.Message trace.write("sqlexception",strErrorString) Next
Please note the commented RAISERROR statement. If I uncomment this statement, I will get a return value of 11 records. If I leave it out, I get zero records. The data is the database should return 11 records, based on the criteria of age > 11
execute sp_executesql @strQuery statement in my SP. and My is @strQuery = "Insert into @tmp_tbl select ...". I have created @tmp_tbl using "
DECLARE @tmp_tbl TABLE(rownum ...... ".
its giving me error "
Must declare the table variable "@tmp_tbl". while executing : execute sp_executesql @strQuery statement.
How to pass that table variable with executesql ?? As i understand, i created table @tmp_tbl in my SP and trying to access it inside system SP sp_executesql . so its not working.
Is there a way to pass table variable as parameter to sp_executesql ??
trying to create SP with parameter and i want to use current date getdate() as parameter.. doesn't seem to work. do i have to use getdate in where clause?
here my SP
CREATE PROC report (@date datetime) SET @date = (getdate())-1 as SELECT..here goes my select statement where (@date = mydatecolumindatebase)
but im getting error on line 3 and 4 ........ Server: Msg 156, Level 15, State 1, Procedure getdatetest, Line 3 Incorrect syntax near the keyword 'SET'. Server: Msg 156, Level 15, State 1, Procedure getdatetest, Line 4 Incorrect syntax near the keyword 'as'.
What happened to being able to pass GETDATE() to a stored procedure? I can swear I've done this in the past, but now I get syntax errors in SQL2005. Is there still a way to call a stored proc passing the current datetime stamp? If so, how? This code: EXEC sp_StoredProc 'parm1', 'parm2', getdate() Gives Error: Incorrect Suntax near ')' I tried using getdate(), now(), and CURRENT_TIMESTAMP with the same result I know I can use code below but why all the extra code? And, what if I want to pass as a SQL command [strSQL = "EXEC sp_StoredProc 'parm1', 'par2', getdate()" -- SqlCommand(strSQL, CN)]? DECLARE @currDate DATETIME SET @currDate = GETDATE() EXEC sp_StoredProc 'parm1', 'parm2', @currDate Thanks!
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?
I'm using some files to show certain pages on certain date for an example
File name : aa.doc start date: 10/02/00 end date : 10/03/00
But it expires on 10/02/00, here is the strored procedure:
Before the date comes, it expires the page Here is my stored procedure:
" SELECT startdate, enddate,archivedate and (startdate is null or (getdate() >= startdate and getdate() <= enddate)) and (archivedate is null or (getdate() <= archivedate)) group by startdate, enddate order by startdate desc "
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.
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 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 EXEC sp_execute sqlstmt. Here is piece of code.
DECLARE C1 CURSOR FOR SELECT NAME FROM SYSOBJECTS WHERE XTYPE='U' OPEN c1 FETCH NEXT FROM C1 INTO @v_TableName WHILE @@FETCH_STATUS = 0 BEGIN SELECT @v_SQL= 'DROP TABLE ' + @v_TableName --EXEC @v_SQL PRINT @v_SQL IF @v_Error<>0 BEGIN SELECT @ErrorCount=@ErrorCount+1 PRINT 'ERROR OCCURED WHILE DROPING TABLE ' + @v_TableName --GOTO ErrorHandler END FETCH NEXT FROM C1 INTO @v_TableName END CLOSE c1 DEALLOCATE C1
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
Hi all,Can sp_executesql used inside a user defined function, itried but it has compiled well, but when i call the functio it showsOnly functions and extended stored procedures can be executed fromwithin a function.What i have went wrongThanks in advancethomson
I have a full sql statement which was generated dynamicly, and need toexecute that string and then take the output and generate aspreadsheet document based on the output. I'm new to sql and the bookI have doesn't really explain much. Anyone with an example of theirwork would be appreaciated.thank you.
(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.
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 @sql = @sql + 'where title LIKE ' + '''%@x1%''' + ' OR notes like ' + '''%@x1%''' 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%'-----------------------------------------------------------------------------------------------------------But this works: BEGIN FETCH NEXT FROM keyword_cursor into @1 SELECT @sql = @sql + 'where title LIKE ''%''+ @x1 + ''%'' OR notes like ''%'' + @x1 + ''%''' 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 try to write query that use sp_executesql to query data by Like operation with 1 parameter like below: execute sp_executesql N'SELECT DISTINCT au_id, au_lname,au_fname FROM authors WHERE au_lname LIKE @au_lname ', N'@au_lname nVarChar', @au_lname = N'%Cas%'
but It return all rows regardless of changing condition to any value.

I am new to this and cannot figure out how. Can someone please guide me? thank you!!
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 created that code to prove if it works. But the result doesn´t appear, and the message is:
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?
I'm trying to build a stored procedure with parameters and sp_executesql. I can't seem to get the types correct. I have two parameters I want to pass: @ADDIVNumber which will be a bigint and @Where which can be varchar(500). I can't seem to figure out how to get the varible types right.

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:
