MySQL查询数据库中的表占用空间的大小

2022-7-22

1、查看指定数据库中各表占用空间的大小

select
table_schema as '数据库',
table_name as '表名',
table_rows as '记录数',
truncate(data_length/1024/1024, 2) as '数据容量(MB)',
truncate(index_length/1024/1024, 2) as '索引容量(MB)'
from information_schema.tables where table_schema='数据库名称'
order by data_length desc, index_length desc

select

table_schema as '数据库',

table_name as '表名',

table_rows as '记录数',

truncate(data_length/1024/1024, 2) as '数据容量(MB)',

truncate(index_length/1024/1024, 2) as '索引容量(MB)'

from information_schema.tables where table_schema='数据库名称'

order by data_length desc, index_length desc

2、查看各数据库占用空间的大小

select
table_schema as '数据库',
sum(table_rows) as '记录数',
sum(truncate(data_length/1024/1024, 2)) as '数据容量(MB)',
sum(truncate(index_length/1024/1024, 2)) as '索引容量(MB)'
from information_schema.tables group by table_schema 
order by sum(data_length) desc, sum(index_length) desc;

select

table_schema as '数据库',

sum(table_rows) as '记录数',

sum(truncate(data_length/1024/1024, 2)) as '数据容量(MB)',

sum(truncate(index_length/1024/1024, 2)) as '索引容量(MB)'

from information_schema.tables group by table_schema

order by sum(data_length) desc, sum(index_length) desc;
