在 ON COMMIT 下,当基表发生DML操作并提交commit 的时候,实体化视图被刷新。 Oracle不允许实体化视图中有self-jions 的存在。 假如指定刷新方式为REFRESH FAST, oracle 执行附加的校验,以确定fast refresh能被执行。这些附加的检查包括: 1 每个基表下必须创建相应的 materialized view log 2 每个基表的rowid 必须...

创建语句:create materialized view mv_name as select * from table_name 默认情况下,如果没指定刷新方法和刷新模式,则Oracle默认为FORCE和DEMAND。 物化视图的数据怎么随着基表而更新? Oracle 提供了两种方式,手工刷新和自动刷新,默认为手工刷新。也就是说,通过我们手工的执行某个Oracle提供的系统级存储过程或包,来...
1、首先基于基表创建物化视图日志: create materialized view log on scott.emp with rowid; 2、首先基于scott用户下emp创建物化视图: create materialized view mv_emp REFRESH FAST on commit as select * from scott.emp; 3、通过oracle 10046 查看update语句执行过程: (1)sql>alter session set sql_trace=tru...
