1. 查看该数据库实例下所有库大小，得到的结果是以MB为单位

  1. mysql> select table_schema,sum(data_length)/1024/1024 as data_length,sum(index_length)/1024/1024 \
  2. as index_length,sum(data_length+index_length)/1024/1024 as sum from information_schema.tables;
  3. +--------------------+---------------+--------------+---------------+
  4. | table_schema       | data_length   | index_length | sum           |
  5. +--------------------+---------------+--------------+---------------+
  6. | information_schema | 2734.92757511 |  86.27539063 | 2821.20296574 |
  7. +--------------------+---------------+--------------+---------------+

2、查看该实例下各个库大小

  1. mysql>  select table_schema, sum(data_length+index_length)/1024/1024 as total_mb, \
  2. sum(data_length)/1024/1024 as data_mb, sum(index_length)/1024/1024 as index_mb, \
  3. count(*) as tables, curdate() as today from information_schema.tables group by table_schema order by 2 desc;
  4. +--------------------+---------------+---------------+-------------+--------+------------+
  5. | table_schema       | total_mb      | data_mb       | index_mb    | tables | today      |
  6. +--------------------+---------------+---------------+-------------+--------+------------+
  7. | data_1234567890    | 2820.59610939 | 2734.39689064 | 86.19921875 |     65 | 2015-11-02 |

  10. +--------------------+---------------+---------------+-------------+--------+------------+

3、查看单个库的大小

  1. mysql> select concat(truncate(sum(data_length)/1024/1024,2),'mb') as data_size, \
  2. concat(truncate(sum(max_data_length)/1024/1024,2),'mb') as max_data_size, \
  3. concat(truncate(sum(data_free)/1024/1024,2),'mb') as data_free, \
  4. concat(truncate(sum(index_length)/1024/1024,2),'mb') as index_size\
  5.  from information_schema.tables where table_schema = 'erongtu_tyb2014';
  6. +-----------+------------------+-----------+------------+
  7. | data_size | max_data_size    | data_free | index_size |
  8. +-----------+------------------+-----------+------------+
  9. | 2734.40mb | 83483426815.99mb | 14.06mb   | 86.19mb    |
  10. +-----------+------------------+-----------+------------+

4、查看单个表的状态

  1. mysql> show table status from data_1234567890 where name = 'data_1234567890_ss' \G
  2. *************************** 1. row ***************************

  19.  Create_options:
  20.         Comment:
  21. 1 row in set (0.00 sec)

5、查看单库下所有表的状态

  1. mysql> select table_name, (data_length/1024/1024) as data_mb , (index_length/1024/1024) \
  2. as index_mb, ((data_length+index_length)/1024/1024) as all_mb, table_rows \
  3. from information_schema.tables where table_schema = 'data_1234567890';
  4. +---------------------------+---------------+-------------+---------------+------------+
  5. | table_name                | data_mb       | index_mb    | all_mb        | table_rows |
