,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‘,

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