导读：复制代码代码如下: SELECT a.`TABLE_SCHEMA` AS DB_NAME,a.`TABLE_NAME`,a.`TABLE_ROWS`,a.`ENGINE` --,a.* FROM information_schema.`TABLES` a LEFT JOIN information_schema.`TABLE_CONSTRAINTS` b ON a.`TABLE_NAME` = b.`TABLE_NAME` AND a.`TABLE_SCH

复制代码代码如下:
SELECT a.`TABLE_SCHEMA` AS DB_NAME,a.`TABLE_NAME`,a.`TABLE_ROWS`,a.`ENGINE` --,a.*
FROM
information_schema.`TABLES` a
LEFT JOIN information_schema.`TABLE_CONSTRAINTS` b
ON a.`TABLE_NAME` = b.`TABLE_NAME` AND a.`TABLE_SCHEMA` = b.`TABLE_SCHEMA`
WHERE b.`TABLE_SCHEMA` IS NULL
AND a.`TABLE_TYPE` = 'BASE TABLE'
AND a.`TABLE_SCHEMA` NOT IN ('information_schema','test','mysql','performance_schema')
ORDER BY DB_NAME,a.`TABLE_ROWS` DESC ;
