----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;
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!
