  记录一下mysql中查看所有表的记录数:

  TABLE_SCHEMA : 数据库名

  TABLE_NAME:表名

  ENGINE:所使用的存储引擎

  TABLES_ROWS:记录数

  DATA_LENGTH:数据大小  得到的结果是以字节为单位,除1024为K,除1048576(=1024*1024)为M

  INDEX_LENGTH:索引大小

  use information_schema;

  select table_schema,table_name,table_rows from tables order by table_rows desc;

  查看指定数据库大小:

  SELECT sum(DATA_LENGTH)+sum(INDEX_LENGTH) FROM information_schema.TABLES where

  TABLE_SCHEMA='数据库名';

  得到的结果是以字节为单位,除1024为K,除1048576(=1024*1024)为M
