wjc_3306

--远程建立物化视图：    --要求：DB1,DB2 要在DB2中建立物化视图，基表是DB1中的mytest表.   --步骤：1.在DB2中建立dblink可以访问db1,create database link DL_DB1 connect to db1username identified by db1password using 'db1servicename';   --如果没有在tnsnames.ora中建立连接可以这样写    create database link DL_DB1 connect to db1username identified by db1password using '(DESCRIPTION =    (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))    (CONNECT_DATA =      (SERVER = DEDICATED)      (SERVICE_NAME = db1)    )  )'  --查看连接的sql  select * from all_db_links;  --2.在db1中建立物化视图日志  create materialized view log on mytest2 with primary key;  --3.在db2中建立视图  create materialized view v_mytest     refresh fast on demand      with primary key     start with sysdate next sysdate+1/1440     as select * from mytest;
