sql

查询所有数据库占用磁盘空间大小的SQL语句:

select TABLE_SCHEMA, concat(truncate(sum(data_length)/1024/1024,2),' MB') as data_size,
concat(truncate(sum(index_length)/1024/1024,2),'MB') as index_size
from information_schema.tables
group by TABLE_SCHEMA
order by data_length desc;

 

查询单个库中所有表磁盘占用大小的SQL语句:

select TABLE_NAME, concat(truncate(data_length/1024/1024,2),' MB') as data_size,
concat(truncate(index_length/1024/1024,2),' MB') as index_size
from information_schema.tables where TABLE_SCHEMA = 'TestDB'
group by TABLE_NAME
order by data_length desc;

注意替换以上的TestDB为具体的数据库名
