Oracle通过dblink创建物化视图

前提条件:源端表名c##hbhe.T1,在目标端创建DBLINK名为NODE02DBLINK​

1.在源端创建物化视图日志

SQL> CREATE MATERIALIZED VIEW LOG ON C##HBHE.T1  
  2  WITH PRIMARY KEY  
  3  INCLUDING NEW VALUES;

Materialized view log created.

2.在目标端授权C##HBHE用户

grant create table to c##hbhe;
grant unlimited tablespace to c##hbhe;
GRANT CREATE MATERIALIZED VIEW  TO c##HBHE;
GRANT ON COMMIT REFRESH to C##hbhe;
GRANT GLOBAL QUERY REWRITE TO c##hbhe;
grant global query rewrite to c##hbhe;
grant advisor to c##hbhe;
grant create any materialized view to c##hbhe;
grant create any view to c##hbhe;
grant select any table to c##hbhe;
grant select any dictionary to c##hbhe;

3.在目标端创建物化视图​

SQL> CREATE MATERIALIZED VIEW HBHE_TEST1 --创建物化视图  
  2  BUILD IMMEDIATE  --在视图编写好后创建  
  3  REFRESH FAST WITH PRIMARY KEY  --根据主表主键增量刷新(FAST，增量)  
  4  ON DEMAND  -- 在用户需要时，由用户刷新  
  5  ENABLE QUERY REWRITE  --可读写  
  6  AS  
  7  SELECT * FROM c##hbhe.T1@NODE02DBLINK;

Materialized view created.
