1.查看mysql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。
2.查看表的最后mysql修改时间
select TABLE_NAME,UPDATE_TIME from INFORMATION_SCHEMA.tables where TABLE_SCHEMA='数据库名';
可以通过查看数据库中表的mysql修改时间，来确定mysql数据库是否已经长期不再使用。
