Hey there, quick question for you gurus: I have a very simple stored procedure that creates two tables, my requirement is to output the numbe of rows inserted into each table, I stumbled across @@ROWCOUNT and this has allowed me to return the value from the last table, or if I put that in between, execution stops immediately after - which is not good, this is my code: Any suggestions … For any type of cursor, if the cursor is closed, then a null value is passed back to the calling batch, procedure, or trigger. This data will be passed back to my .NET application with a reader for parsing. PRINT (Transact-SQL) The @SalesPerson parameter would receive an input value specified by the calling program. For small result sets, the results will be spooled for return to the client and execution will continue. The result set RS returned to the caller consists of rows from 6 through 100 of RS, and the cursor in the caller is positioned before the first row of RS. The execute statement would pass the @SalesYTDBySalesPerson variable value into the @SalesYTD OUTPUT parameter. Next, execute a batch that declares a local cursor variable, executes the procedure to assign the cursor to the local variable, and then fetches the rows from the cursor.
