功能: 用於備份當前用戶所擁有的所有PL/SQL objects (包括<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />
TYPE,TYPE BODY, PROCEDURE , FUNCTION, PACKAGE, PACKAGE BODY or JAVA SOURCE )
原理: 對USER_SOURCE數據字典的調用,得到所有的
PL/SQL 代碼.
使用方法舉例:
1. 在C盤建立目錄C:/EXPORT
2. 將EXPORT_SOURCE.SQL和EXTRACT_SOURCE.SQL拷貝到C盤根目錄.
3. 登陸SQLPLUS , CONNECT SCOTT/TIGER
5. 執行結束,所有的SCOTT擁有的PL/SQL object的代碼文件建立在C:/EXPORT目錄裏．
後綴名.PKS 表示PACKAGE
後綴名.PKB 表示PACKAGE BODY
後綴名.SQL 表示其他OBJECTS
備註：
如果想得到數據庫中各個SCHEMA的PL/SQL objects ,只需把工具代碼中的USER_SOURCE改成DBA_SOURCE,由SYSTEM
運行即可.
