However, if I removed Drop Table command, all worked fine. Returning rowcount from a stored procedure: Author: Topic : gbaia Yak Posting Veteran. This data will be passed back to my .NET application with a reader for parsing. The SELECT statement uses the value passed into the input parameter to obtain the correct SalesYTD value.

You can return from a stored procedure at any point to end the execution of the procedure. Then in the procedure body, the value could be used for calculations that generate a new value. set nocount on. No error is returned, but you cannot use the output value in the calling program.

The following rules pertain to cursor output parameters when the procedure is executed: For a forward-only cursor, the rows returned in the cursor's result set are only those rows at and beyond the position of the cursor at the conclusion of the procedure execution, for example: A nonscrollable cursor is opened in a procedure on a result set named RS of 100 rows. The rows affecting statement can be any INSERT, UPDATE, DELETE or SELECT statement that is executed directly before the @@ROWCOUNT execution, taking into consideration that both the rows affecting statement and the system variable calling query are in the same execution. This behavior also applies to nested TSQL batches, nested stored procedures and top-level TSQL batches. int int. For a scrollable cursor, all the rows in the result set are returned to the calling batch, procedure, or trigger when the procedure exits. First, create the procedure that declares and then opens a cursor on the Currency table. Because OUTPUT parameters must be bound before an application can execute a procedure, procedures with cursor OUTPUT parameters cannot be called from the database APIs. 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 … Then in your .NET app, you can create SQLParameters on the SQLCommand object which you use to instantiate the SQLDataReader, and fetch the rowcount back into your app. The sproc is called from an “Exec SQL Task”.
