1、进入information_schema 数据库(存放了其他的数据库的信息) use information_schema; 2、查询所有数据的大小: select concat(round(sum(data_length/1024/1024),2),’MB’) as data from tables; 3、查看指定数据库的大小: 比如查看数据库home的大小

1、进入information_schema 数据库(存放了其他的数据库的信息)

use information_schema;

2、查询所有数据的大小:

select concat(round(sum(data_length/1024/1024),2),’MB’) as data from tables;

3、查看指定数据库的大小:

比如查看数据库home的大小

select concat(round(sum(data_length/1024/1024),2),’MB’) as data from tables where table_schema=’home';

4、查看指定数据库的某个表的大小

比如查看数据库home中 members 表的大小

select concat(round(sum(data_length/1024/1024),2),’MB’) as data from tables where table_schema=’home’ and table_name=’members';
