如何让普通用户可以对DBA_SOURCE视图进行闪回查询？
赋权：
GRANT SELECT , FLASHBACK ON DBA_SOURCE TO LHR10;
或：
GRANT DBA,SELECT_CATALOG_ROLE TO LHR10;
LHR@orclasm > DROP USER LHR10;
CREATE USER LHR10 IDENTIFIED BY LHR;
GRANT RESOURCE TO LHR10;
User dropped.
LHR@orclasm >
User created.
LHR@orclasm >
Grant succeeded.
LHR@orclasm > LHR@orclasm > LHR@orclasm > LHR@orclasm >
LHR@orclasm >
LHR@orclasm >
LHR@orclasm > CONN LHR10/LHR;
ERROR:
