表查询互相授权

--需要被查询的用户登录oracle（假如为mis）   B为要查询misapp用户下的表的用户

--查询语句
select 'grant select on mis.'|| tname ||' to  misapp;' from tab;
 
--授权
grant select on mis.DEPARTMENT to  misapp;
grant select on mis.MENULIST to  misapp;
grant select on mis.MIS_OPERATIONLOG to  misapp;
grant select on mis.REL_SYS_ROLE_MENU to  misapp;
grant select on mis.REL_SYS_SYS to  misapp;
grant select on mis.REL_USER_DEP to  misapp;
grant select on mis.REL_USER_ROLE to  misapp;
grant select on mis.REL_USER_SYS_DEPT to  misapp;
grant select on mis.ROLELIST to  misapp;
grant select on mis.SYSLIST to  misapp;
grant select on mis.SYSTEMLOG to  misapp;
grant select on mis.SYS_MANAGER to  misapp;
grant select on mis.USERLIST to  misapp;
grant select on mis.USER_MENU_STAT to  misapp;
