A stored procedure is a group of Transact-SQL statements
compiled into a single execution plan.

Stored procedures return data in four ways:
* Output parameters, which can return either data (such
as an integer or character value) or a cursor variable
(cursors are result sets that can be retrieved one row at a
time).
* Return codes, which are always an integer value.
* A result set for each SELECT statement contained in
the stored procedure or any other stored procedures called
by the stored procedure.
* A global cursor that can be referenced outside the
stored procedure.
