In the last two phases of the DB2 project, data in the temporary table needs to be transferred to the formal table during the system idle period, or some time-consuming operations must be performed on some tables in the background. Stored procedures are required.
Basic concepts:
Stored procedures are stored procedure, which is generally referred to as procedure. To learn this, you must first understand another concept: routine, which is generally tran
