Question

I am attempting to execute a Stored Procedure within another stored procedure. The catch is that the stored procedure name is dynamically built within the first procedure. Here is an example of what I am trying to do …

CREATE PROCEDURE SPINSVALUE_12345     @guid uniqueidentifier AS     DECLARE @returnValue bit     DECLARE @spToExec NVARCHAR(255)     SET @returnValue = 0     WHILE (@returnValue=0)     BEGIN          SET @spToExec = 'SPINSVALUE_' + REPLACE(@guid, '-', '_')          ... DO OTHER STUFF ...          EXEC sp_executeSQL @spToExec, N'@returnValue BIT OUTPUT', @returnValue OUTPUT     END END 

I can’t seem to get the sp_executeSQL to work. Is it possible to execute a stored procedure this way and get a value from the OUTPUT parameter?

Answer 1

does the proc have a return value or an output value? here is an example

create proc prBlatest as return 5 go   DECLARE @chvTableName VARCHAR(100), @intTableCount INT, @chvSQL NVARCHAR(100)  SELECT @chvTableName = 'prBlatest' SELECT @chvSQL = N'exec @intTableCount = ' + @chvTableName  EXEC sp_executesql @chvSQL, N'@intTableCount INT OUTPUT', @intTableCount OUTPUT  SELECT @intTableCount GO 

BTW I think that this is a bad idea to have many procs that do similar thing, maybe you need to refactor
