Mysql物化视图应用

1、基本api

 //第一步：创建物化视图 

call flexviews.CREATE('demo',
                      'mv_company_sales_items_monthly',
                      'INCREMENTAL'
                      );

----------数据库、视图名称、刷新类型（增量刷新）

 

//获取视图id

select @mvid := last_insert_id();

  //第二步：增加表，where条件用到

call flexviews.add_table(@mvid, 'demo', 'orders', 'o', 'USING(CustomerId)');

-----视图id，数据库名称、表名称、表别名，条件

v_mview_id - The materialized view id (see flexviews.get_id)

v_table_schema - The schema which contains the table to add

v_table_name - The name of the table to add

v_table_alias - The table alias to use in the view. All tables MUST have an alias.

v_join_clause - Every table after the first must have a NOT-NULL join clause

//第三部：

 

//第四部：物化视图

call flexviews.enable(@mvid);
