你需要創(chuàng)建這些刪除語句,，通過oracle的數(shù)據(jù)字典找到該用戶下的所有表、視圖等對象，拼接成語句,。如下
select 'drop table ' || table_name ||';'||chr(13)||chr(10) from user_tables; --delete tables
select 'drop view ' || view_name||';'||chr(13)||chr(10) from user_views; --delete views
select 'drop sequence ' || sequence_name||';'||chr(13)||chr(10) from user_sequences;--delete seqs
select 'drop function ' || object_name||';'||chr(13)||chr(10) from user_objects where object_type='FUNCTION';--delete functions
select 'drop procedure ' || object_name||';'||chr(13)||chr(10) from user_objects where object_type='PROCEDURE';--DELETE PROCEDURE
select 'drop package ' || object_name||';'||chr(13)||chr(10) from user_objects where object_type='PACKAGE';--delete pags
