没有AUTHID CURRENT_USER表示定义者权限(definer rights),以定义者身份执行;加上AUTHID CURRENT_USER表示调用者权限(invoker rights),以调用者身份执行。
例:
1. 创建两个用户:xxpo,xxgl
2. 在xxpo下创建一张表:xxpo_authid_test
3. 在xxpo下创建如下两个procedure
3.1 xxpo_no_authid_test_prc:
3.2 xxpo_has_authid_test_prc:
4. 将两个procedure的执行权限(EXECUTE)赋予xxgl:
5. 在xxgl分别调用xxpo下面的两个procedure,查看结果:
由于我们并没有在xxgl用户下创建一个名为xxpo_authid_test的表,所以当我们在xxgl用户下以调用者(xxgl)权限去执行xxpo.xxpo_has_authid_test_prc这个procedure的时候,会报表不能找到(ORA-00942)的错误;而以定义者(xxpo)权限去执行则不存在此问题。
