Oracle 11g創建遠程物化視圖時提示“ORA-01788: 此查詢塊中要求 CONNECT BY 子句”的解決方案

將遠程服務器的一個表映射為本地的一個物化視圖，使用下列語句：

----建立測試環境DBLINK:
create database link lnk
  connect to user1
  identified by pwd1
  using '(DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(Host = 172.17.211.114)(PORT = 1521))) (CONNECT_DATA = (SERVER = DEDICATED) (SID= REMOTEDB)))';

--創建物化視圖，每隔兩天自動同步更新一次；
  CREATE MATERIALIZED VIEW DEPARTMENT  
     REFRESH FORCE                 
     START WITH SYSDATE                   
     NEXT  SYSDATE + 2                  
     WITH PRIMARY KEY       
  AS SELECT * FROM user1.DEPARTMENT@lnk WHERE 1＝1;     

 

結果提示："ORA-01788: 此查詢塊中要求 CONNECT BY 子句"。

google無法訪問，百度搜索太扯蛋，用必應，總算得到線索，解決方案：

在本地庫中執行如下語句：

ALTER SYSTEM SET "_ALLOW_LEVEL_WITHOUT_CONNECT_BY"=TRUE SCOPE=BOTH 

 

OK!
