OK, I'm fairly new to SQL Server, but I know SQL and databases pretty well. I'm just starting to use the dynamic SQL feature of SQL Server (with EXEC), and am wondering how to return a scalar value from a dynamic SQL expression. I realize I can't use EXEC in a user-defined function, but I want to create a stored procedure with one OUTPUT variable so I can simulate a function. The following code does not work, because EXEC does not return a value:
Hi, I have an sql query like this :DECLARE @TableName varchar(200), @ColumnName varchar(200), @EmployeeID varchar(200), @Result varchar(200);SET @TableName = 'Customer';SET @ColumnName = 'First_Name';SET @CustomerID = 28;-- This line return ErrorSET @Result = EXEC ('select' + @ColumnName + ' from ' + @TableName + ' where Recid = ' + @CustomerID + '');Print @Result; I am pretty sure the SELECT statement in EXEC will only return 0 or 1 record. But how to capture result from EXEC? Thanks
Hi I have a maintenance proceudre that trims data tables on the live site, but prior to trimming i need to execute procs via linked servers at four seprate locations (subscribers) to ensure all of their data is up to date before the trim happens (the deletes are blocked at the subs). my problem is that if i go exec @error_id = procname and an error such as permission being denied or proc missing, the return code is still 0 - therefor it looks like th proc ran successfully, meanwhile it didnt. does anyone know how to check for these sorts of erors, so i dont leave this to chance?
I am trying to find a way to return the result of an EXEC(*sqlstring*) from a function. I can return the tsql but not the result of an execute.
This is my function:
ALTER FUNCTION [dbo].[ReturnPickItemValue] ( -- Add the parameters for the function here @TypeID int, @CaseID int ) RETURNS varchar(max) AS BEGIN -- Declare the return variable here DECLARE @RTN varchar(max)
IF(SELECT IncludeDates FROM TBL_LU_PICK WHERE PickTypeID = @TypeID) = 1 BEGIN SET @RTN = 'SELECT PickItem I + CASE D.IsStartDateEstimated WHEN 0 THEN CAST(StartDate as varchar) ELSE CAST(dbo.ReturnEstimatedDate(D.IsStartDateEstimated, 0) as varchar) END + CASE D.IsEndDateEstimated WHEN 0 THEN CAST(EndDate as varchar) ELSE CAST(dbo.ReturnEstimatedDate(D.IsEndDateEstimated, 1) as varchar) END
FROM TBL_LU_PICK L INNER JOIN TBL_Pick_Items I ON I.PickTypeID = L.PickTypeID INNER JOIN TBL_PICK P ON P.PickItemID = I.PickItemID LEFT JOIN TBL_PickDates D ON D.PickID = P.PickID WHERE L.PickTypeID = ' + CAST(@TypeID as varchar) + ' AND P.CaseID = ' + CAST(@CaseID as varchar) END ELSE BEGIN SET @RTN= 'SELECT I.PickItem FROM TBL_LU_PICK L INNER JOIN TBL_Pick_Items I ON I.PickTypeID = L.PickTypeID INNER JOIN TBL_Pick P ON P.PickItemID = I.PickItemID WHERE L.PickTypeID = ' + CAST(@TypeID as varchar) + ' AND CaseID = ' + CAST(@CaseID as varchar) END
RETURN @RTN
END
Each time I try " RETURN EXEC(@RTN) " or something similar I get an error.
I have tried executing the tsql and assigning the result to a varchar and returning that varchar but i get an error.
I use new query to execute my store procedure but didnt return any value is that any error for my sql statement??

I am just trying to capture the return code from a stored proc as follows and if I get a 1 I want the SQL Task to follow a failure(red) constrainst workflow and send a SMTP mail task warning the customer. How do I achieve the Exec SQL Task portion of this, i get a strange error message [Execute SQL Task] Error: There is an invalid number of result bindings returned for the ResultSetType: "ResultSetType_SingleRow".
Using OLEDB connection, I utilize SQL: EXEC ? = dbo.CheckCatLog
EXEC SQL Task Editer settings: RESULTSET: Single Row PARAMETER MAPPING: User::giBatchID DIRECTION: OUTPUT DATATYPE: LONG PARAMETER NAME: 0
PS-Not sure if I need my variable giBatchID which is an INT32 but I thought it is a good idea to feed the output into here just in case there is no way that the EXEC SQL TASK can chose the failure constrainst workflow if I get a 1 returned or success constraint workflow if I get a 0 returned from stored proceedure
CREATE PROCEDURE CheckCatLog @OutSuccess INT AS
-- SET NOCOUNT ON added to prevent extra result sets from -- interfering with SELECT statements. SET NOCOUNT ON DECLARE @RowCountCAT INT DECLARE @RowCountLOG INT
---these totals should match SELECT @RowCountCAT = (SELECT Count(*) FROM mydb_Staging.dbo.S_CAT) SELECT @RowCountLOG = (SELECT Count(*) FROM mydb_Staging.dbo.S_LOG) --PRINT @RowCountCAT --PRINT @RowCountLOG BEGIN IF @RowCountCAT <> @RowCountLOG --PRINT 'Volume of jobs from the CAT file does not match volume of jobs from the LOG file' --RETURN 1 SET @OutSuccess = 1 END GO
I use OdbcConnection inside clr procedure, for getting data. If I use simple EXEC dbo.clr_proc - all is OK. If I use INSERT...EXEC I recive error message: Distributed transaction enlistment failed.
I set MSDTC security options for No Authentification and Allow inbound and Allow outbound, but it's no use.
Have this problem solution? May be, I must use another method to get my data?
P.S. Linked Servers and OPENQUERY is not applicable. Sybase not describe columns in stored proc result set and one stored proc may return different result set by params.
I have a package that I have been attempting to return a error code after the stored procedure executes, otherwise the package works great.
I call the stored procedure from a Execute SQL Task (execute Marketing_extract_history_load_test ?, ? OUTPUT) The sql task rowset is set to NONE. It is a OLEB connection.
I have two parameters mapped:
tablename input varchar 0 (this variable is set earlier in a foreach loop) ADO. returnvalue output long 1
I set the breakpoint and see the values change, but I have a OnFailure conditon set if it returns a failure. The failure is ignored and the package completes. No quite what I wanted.
The first part of the sp is below and I set the value @i and return.
Why is it not capturing and setting the error and execute my OnFailure code? I have tried setting one of my parameter mappings to returnvalue with no success.
This is my function, it returns SQLDataReader to DATALIST control. How to return page number with the SQLDataReader set ? sql server 2005, asp.net 2.0

This is what i am calling DataList1.DataSource = get_all_events() DataList1.DataBind()
How to return records and also the return value of pagecount ? i tried many options, nothing work. Please help !!. I am struck
I'm trying to create a report that's based on a SQL-2005 Stored Procedure.
I added the Report Designer, a Report dataset ( based on a shared datasource).
When I try to build the project in BIDS, I get an error. The error occurs three times, once for each parameter on the stored procedure.
I'll only reproduce one instance of the error for the sake of brevity.
[rsCompilerErrorInExpression] The Value expression for the query parameter 'UserID' contains an error : [BC30654] 'Return' statement in a Function, Get, or Operator must return a value.
I've searched on this error and it looks like it's a Visual Basic error :
I am trying to bring my stored proc's into the 21st century with try catch and the output clause. In the past I have returned info like the new timestamp, the new identity (if an insert sproc), username with output params and a return value as well. I have checked if error is a concurrency violation(I check if @@rowcount is 0 and if so my return value is a special number.)
I have used the old goto method for trapping errors committing or rolling back the transaction.
Now I want to use the try,catch with transactions. This is easy enough but how do I do what I had done before?
I get an error returning the new timestamp in the Output clause (tstamp is my timestamp field -- so I am using inserted.tstamp).
Plus how do I check for concerrency error. Is it the same as before and if so would the check of @@rowcount be in the catch section?
So how to return timestamp and a return value and how to check for concurrency all in the try/catch.
by the way I read that you could not return an identity in the output clause but I had no problem.
i have using BCP to output SP return data into txt file, however, when it return nothing , it give SQLException like "no rows affected" , i have try to find out the solution , which include put "SET NOCOUNT ON" command before select statement, but it doesn't help :(
anyone know how to handle the problem when SP return no data ?
I have a stored procedure that selects the unique Name of an item from one table.
SELECT DISTINCT ChainName from Chains
For each ChainName, there exists 0 or more StoreNames in the Stores. I want to return the result of this select as the second field in each row of the result set.
SELECT DISTINCT StoreName FROM Stores WHERE Stores.ChainName = ChainName
Each row of the result set returned by the stored procedure would contain:
ChainName, Array of StoreNames (or comma separated strings or whatever)
When I use EXEC in a stored procedure ( after building complex option logic) it produces an returns an error of 'Access denied' on the underlying tables. All objects are dbo owned and execute permission has been given to all users. Can ant one help? Rob
When using a SP for getting a recordset is there any issues with using exec like in: rs.open "exec spWhatever"... Should I use rs.open "spWhatever" or does it really matter performance wise on the SQL server?
declare @TableName Varchar(255);--Just For Testing---DELETE!! declare @Filename varchar(255); --Store Distinct filename declare @DSNo Varchar(255);-- Use 'set' to execute Var TableName declare @SumUnits Varchar(255); --Use 'set' to calculate sum of units declare @SumValue Varchar(255); Set @TableName = 'TrDs01' -- Testing Only--DELETE!!

Just the Bold and underlined bit "exec(DSNo)"..... is this doable in some way? can i use exec to retrieve the value to insert to data supplier. As far as i know i have to do it like this because im using a variable as the table name...
I need help understanding the syntax of the "exec sql" statement.
i am looking at code that build an sql string such as
sql="exec SOMETHING Session("id")"
or something like that.
then, there is
conn.execute(sql)
My question is the "SOMETHING" in the sql statement...is what? I know it is user defined (object or variable or such), but what exactly is it? i look through the rest of the code and don;'t see SOMETHING defined elsewhere.
i am not sure if i am asking the question right. i don't understand what the SOMETHING is doing, or why it is there.
i understand the this statement will delete a record, but how does it handle "SurveyDelete", how does it know what the is when it is not defined anywhere else in the code?
is it possible to have a sproc with a input parm of a column name and have this column name be inserted into an exec statement that runs and provides the output as a OUTPUT parm instead of a result set?
i can get the sproc to take the column name as a parm, run the exec, but cannot figure out how to assign the "dynamic sql" output to a OUTPUT variable instead of returning the result set.
I found this statement in BOL and it didn't make it to work.Is anybody out there who ha the same problem? Database is MASTER. USE master EXEC ("USE pubs") SELECT * FROM authors
Running this dynamic sql construct gives me an error because somehow it does not accept my variable @table or it is recognised differently. If run directly no problem but apparently the single quotes are a problem.
Print @Table (db and table name: opms..transactions) Select @sql = 'Select * From Payments where not exists (Select * from Hist Where TableName = ' + @Table + ' and sYear = '+ @Year + ' and sMonth = ' + @Month + ')' Print @sql EXEC (@sql)
opms..Transactions Select * From Payments where not exists (Select * from Hist Where TableName = opms..Transactions and sYear = 2003 and sMonth = 12)
Server: Msg 1004, Level 15, State 1, Line 1 Invalid column prefix 'opms.': No table name specified
I am seeking an expert help for the following issue, please find the code am using first ...the problem mentioned below that... ---------------------------------------------- DECLARE ,@DBName VARCHAR(128) ,@LoginName VARCHAR(128) ,@SQL VARCHAR(2000)
EXEC(@SQL) IF @@ERROR <> 0 PRINT @@ERROR ELSE BEGIN PRINT 'Revoked database access of [' + @LoginName + '] from the database ['+ @DBName +'] PRINT @@ERROR END --------------------------------------------------------------
Suppose I am trying to REVOKE a database access which not exist iw will give me a mesage like , Server: Msg 15008, Level 16, State 1, Procedure sp_revokedbaccess, Line 36 User 'Loginname' does not exist in the current database.
But the @@ERROR will return 0 as it was a successfull execution of EXEC(@SQL) .
So How can I retrieve the error value 15008 in a variable ..?
I'm trying to do something like the following, but it keeps complaining that I need to declare @max, even though I have (and it is of the same type as link_id).
EXEC('SELECT @max=MAX(link_id) FROM '+ @str1)
I've looked into sp_executesql but I'm not entirely sure how that functions. Any suggestions?
