有简单的刷新脚本：
BEGIN DBMS_SNAPSHOT.REFRESH( LIST => 'SCHEMA_NAME.TABLE_NAME',PUSH_DEFERRED_RPC => TRUE,REFRESH_AFTER_ERRORS => FALSE,PURGE_OPTION => 1,PARALLELISM => 0,ATOMIC_REFRESH => TRUE,NESTED => FALSE); END;
甲骨文辩称：
ORA-00942: table or view does not exist ORA-06512: at "SYS.DBMS_SNAPSHOT",line 2251 ORA-06512: at "SYS.DBMS_SNAPSHOT",line 2457 ORA-06512: at "SYS.DBMS_SNAPSHOT",line 2426 ORA-06512: at line 2 00942. 00000 - "table or view does not exist"
问题：我错过了什么？
注意：
>刷新的MV确实存在
>如果未指定schema,则结果相同
