SQL> grant select on flashback_transaction_query to scott;
Grant succeeded.
问题 1）赋权成功，但scott仍然无法查询该view. 这是为什么呢？
SQL>conn scott/tiger
Connected.
SQL> select xid,commit_scn,commit_timestamp,operation,undo_sql from flashback_transaction_query q where q.xid in(select versions_xid from a versions between scn
*
ERROR at line 1:
ORA-01031: insufficient privileges
问题 2）：
如果sysdb操作： SQL> grant select any transaction to scott;
Grant succeeded.
这个时候scott就可以查看flashback_transaction_query视图了，这又是问什么呢？ |
