----建立测试环境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

----建立测试环境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)))';

--创建物化视图，每隔两天自动同步更新一次；
 CREATE MATERIALIZED VIEW DEPARTMENT 
 REFRESH FORCE 
 START WITH SYSDATE 
 NEXT SYSDATE + 2 
 WITH PRIMARY KEY 
 AS SELECT * FROM user1.DEPARTMENT@lnk WHERE 1＝1;

将远程服务器的一个表映射为本地的一个物化视图，使用下列语句：

结果提示："ORA-01788: 此查询块中要求 CONNECT BY 子句"。

google无法访问，百度搜索太扯蛋，用必应，总算得到线索，解决方案：

在本地库中执行如下语句：

ALTER SYSTEM SET "_ALLOW_LEVEL_WITHOUT_CONNECT_BY"=TRUE SCOPE=BOTH

OK!
