用命令查看:
1、進(jìn)入information_schema
數(shù)據(jù)庫(kù)（存放了其他的數(shù)據(jù)庫(kù)的信息）
use information_schema;

2、查詢所有數(shù)據(jù)的大?。?br/>select
concat(round(sum(data_length/1024/1024),2),'MB') as data from
tables;

3、查看指定數(shù)據(jù)庫(kù)的大?。?br/>比如查看數(shù)據(jù)庫(kù)home的大小
select
concat(round(sum(data_length/1024/1024),2),'MB') as data from tables where
table_schema='home';

4、查看指定數(shù)據(jù)庫(kù)的某個(gè)表的大小
比如查看數(shù)據(jù)庫(kù)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';
