本文主要是介绍查看数据库容量,希望对大家解决编程问题提供一定的参考价值,需要的开发者们随着小编来一起学习吧!
查看表:
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=‘screport’
order by data_length desc, index_length desc;
查看库
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;
