1、查看mysql数据库占用空间大小sql语句
SELECT CONCAT(TRUNCATE(SUM(data_length)/1024/1024,2),'MB') AS data_size,2、查看数据库中单个表占用空间大小sql
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 = '数据库名'
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_NAME = '表名';
