ORA-00980:synonym translation is no longer valid

今天要把測試環境DB的數據更新成最新Production環境的數據，期間發生了一些問題：

1.首先從正式環境exp出想要用戶的dmp檔

2.drop掉測試環境底下相應用戶

3.create測試環境底下相應用戶

4.imp 正式環境導出的dmp檔

5.在測試環境底下explain plan sql時報：ORA-00980: synonym translation is no longer valid

 

用以下語句查下失效的synonym

select 'drop '        || decode (s.owner,                   'PUBLIC', 'public synonym ',                   'synonym ' || s.owner || '.')        || s.synonym_name        || ';' as "Dropping invalid synonyms:"   from dba_synonyms s  where table_owner not in ('SYSTEM', 'SYS') and db_link is null    and not exists           (select null              from dba_objects o             where s.table_owner = o.owner               and s.table_name = o.object_name)

 

發現有個TOAD_PLAN_TABLE的synonym失效，應該是我在砍User的時候，沒有把這個同義詞相應的砍掉

 

解決：drop public synonym TOAD_PLAN_TABLE;
