奇怪的使用dblink创建物化视图的问题

权限已经加好

GRANT CREATE SESSION, UNLIMITED TABLESPACE, CREATE TABLE TO TEST;

GRANT CREATE ANY MATERIALIZED VIEW TO TEST;

但创物化视图报错:

ORA-00942: TABLE OR VIEW does NOT exist
ORA-06512: AT "SYS.DBMS_SNAPSHOT_UTL", line 960
ORA-06512: AT line 1

后来查了一个老外的文章：http://birijan.com.np/?q=ORA-06512+DBMS_SNAPSHOT_UTL+line+960

晕，居然要这样写：as select * from (select * from xxx@db_link)
