1. View basic information of database tables.
select * from information_schema.TABLES where information_schema.TABLES.TABLE_SCHEMA = '数据库名' and information_schema.TABLES.TABLE_NAME = '表名';
2. Check the mysql database size
SELECT sum(DATA_LENGTH)+sum(INDEX_LENGTH) FROM information_schema.TABLES where TABLE_SCHEMA='数据库名';
The result is in bytes, divided by 1024 is K, divided by 1048576 (=1024*1024) is M.
3. Check the last mysql modification time of the table
select TABLE_NAME,UPDATE_TIME from information_schema.TABLES where TABLE_SCHEMA='数据库名' order by UPDATE_TIME desc limit 1;
select TABLE_NAME,UPDATE_TIME from information_schema.TABLES where TABLE_SCHEMA='数据库名' and information_schema.TABLES.TABLE_NAME = '表名';
