create/remove IBM i (as400) 中的行权限 SQL

Question

在 Db2 for IBM i 中，我可以像这样创建行权限。

-- enable row access control
ALTER TABLE QIWS.QCUSTCDT ACTIVATE ROW ACCESS CONTROL;

-- create permission MYPERMISSION999
CREATE PERMISSION MYPERMISSION999 ON SALES.ORDHED
FOR ROWS WHERE VERIFY_GROUP_FOR_USER(SESSION_USER,'MYGROUP') = 1
               AND SCODE = SESSION_USER                  
ENFORCED FOR ALL ACCESS

ENABLE;
COMMIT;
ALTER TABLE SALES.ORDHED ACTIVATE ROW ACCESS CONTROL;
COMMIT;

如果我停用行访问控制，规则似乎消失了，但如果我激活旧规则又回来了。

 ALTER TABLE SALES.ORDHED           
     DEACTIVATE ROW ACCESS CONTROL

Answer 1

DROP PERMISSION MYPERMISSION999;
