檢視mysql資料庫和表所占用空間

1、資料庫所占空間

SELECT CONCAT(TRUNCATE(SUM(data_length)/1024/1024,2),'MB') AS data_size,

CONCAT(TRUNCATE(SUM(max_data_length)/1024/1024,2),'MB') AS max_data_size,

CONCAT(TRUNCATE(SUM(data_free)/1024/1024,2),'MB') AS data_free,

CONCAT(TRUNCATE(SUM(index_length)/1024/1024,2),'MB') AS index_size

FROM information_schema.tables WHERE TABLE_SCHEMA = '資料庫名';

2、表所占空間

FROM information_schema.tables WHERE TABLE_NAME = '表名';
