有時要在測試環境創建跟生産環境同個用戶，但又不知道用戶相關的權限，這裡提供一個實用的腳本。

腳本内容如下：

--執行存儲過程 exec DBMS_METADATA.SET_TRANSFORM_PARAM(DBMS_METADATA.SESSION_TRANSFORM,'SQLTERMINATOR', true); --查詢用戶腳本及權限 SELECT ( CASE WHEN ((SELECT COUNT(*) FROM dba_users WHERE username = '&&Username') > 0) THEN dbms_metadata.get_ddl ('USER', '&&Username') ELSE to_clob (' -- Note: User not found!') END ) extracted_ddl FROM dual UNION ALL SELECT ( CASE WHEN ((SELECT COUNT(*) FROM dba_ts_quotas WHERE username = '&&Username') > 0) THEN dbms_metadata.get_granted_ddl( 'TABLESPACE_QUOTA', '&&Username') ELSE to_clob (' -- Note: No TS Quotas found!') END ) FROM dual UNION ALL SELECT ( CASE WHEN ((SELECT COUNT(*) FROM dba_role_privs WHERE grantee = '&&Username') > 0) THEN dbms_metadata.get_granted_ddl ('ROLE_GRANT', '&&Username') ELSE to_clob (' -- Note: No granted Roles found!') END ) FROM dual UNION ALL SELECT ( CASE WHEN ((SELECT COUNT(*) FROM dba_sys_privs WHERE grantee = '&&Username') > 0) THEN dbms_metadata.get_granted_ddl ('SYSTEM_GRANT', '&&Username') ELSE to_clob (' -- Note: No System Privileges found!') END ) FROM dual UNION ALL SELECT ( CASE WHEN ((SELECT COUNT(*) FROM dba_tab_privs WHERE grantee = '&&Username') > 0) THEN dbms_metadata.get_granted_ddl ('OBJECT_GRANT', '&&Username') ELSE to_clob (' -- Note: No Object Privileges found!') END ) FROM dual

結果如下：

有些場景還是會用到的，大家有興趣可以自己測試一下。
