在参考了
Using DBMS_SYS_SQL Package to grant Privilege留言板里有朋友继续问道,出现了以下错误:
ORA-25191: cannot reference overflow table of an index-organized table
ORA-06512: at "SYS.DBMS_SYS_SQL", line 1474
ORA-06512: at line 9
|
查一下Oracle手册，我们看到:
ORA-25191 cannot reference overflow table of an index-organized table
Cause: An attempt was made to directly access the overflow table of an index-organized table.
Action: Issue the statement against the parent index-organized table containing the specified overflow table.

意思是说，对于Overflow的IOT表，只需要对父表进行授权即可。简单动手自己试试看也可以:
SQL> connect eygle/eygle
Connected.
SQL> CREATE TABLE TEST_IOT
2 (id NUMBER PRIMARY KEY,
3 C1 VARCHAR2(50),
4 C2 VARCHAR2(10))
5 ORGANIZATION INDEX PCTTHRESHOLD 10 OVERFLOW;
Table created.
SQL> col object_name for a30
SQL> select object_name,object_type from user_objects where object_name like '%IOT%';
OBJECT_NAME OBJECT_TYPE
------------------------------ ------------------
SYS_IOT_OVER_7370 TABLE
SYS_IOT_TOP_7370 INDEX
TEST_IOT TABLE
SQL> grant select on SYS_IOT_OVER_7370 to scott;
grant select on SYS_IOT_OVER_7370 to scott
