MySQL 查看数据库表容量大小

1.查看所有数据库容量大小

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;

2.查看所有数据库各表容量大小

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
order by data_length desc, index_length desc;

 

3.查看指定数据库容量大小

例:查看mysql库容量大小
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
where table_schema='mysql';

 

4.查看指定数据库各表容量大小

例:查看mysql库各表容量大小
复制代码
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='mysql'
order by data_length desc, index_length desc;
