The extended stored procedure function is executed under the security context of SQL Server. The extended stored procedure function runs in the process space of SQL Server. The thread associated with the execution of the extended stored procedure is the same one used for the client connection. Imp...
SQL Copy DECLARE @result AS INT; EXECUTE @result = my_proc; GO Return codes are commonly used in control-of-flow blocks within procedures to set the return code value for each possible error situation. You can use the @@ERROR function after a Transact-SQL statement to detect whether an...
These examples use the execute method of the SQLServerCallableStatement class to run the stored procedure. This is used because the stored procedure did not also return a result set. If it did, theexecuteQuerymethod would be used. Stored procedures can return update counts and multiple result sets...
