概述

有时要在测试环境创建跟生产环境同个用户，但又不知道用户相关的权限，这里提供一个实用的脚本。

获取创建用户脚本及权限

脚本内容如下：

--执行存储过程
exec DBMS_METADATA.SET_TRANSFORM_PARAM(DBMS_METADATA.SESSION_TRANSFORM,'SQLTERMINATOR', true);

--查询用户脚本及权限
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

结果如下：

有些场景还是会用到的，大家有兴趣可以自己测试一下。
