Compile all invalid database objects

原创 Linux操作系统 作者:xhailiang 时间:2006-10-11 00:00:00 0 删除 编辑
rem -----------------------------------------------------------------------
rem Filename: cmpall2.sql
rem Purpose: Compile all invalid database objects
rem Run this script after each database upgrade or whenever
rem required.
rem Notes: If the dependencies between objects are complicated, you can
rem end up re-compiling it many times, as recompiling some
rem invalidates others. This script uses dyamic SQL, and
rem recompile objects based on reverse dependency order.
