取得特定 MySQL 資料庫中的非空表清單？

要取得特定 MySQL 資料庫中的非空表列表，語法如下 -

SELECT table_type,table_name, table_schema from information_schema.tables
where table_rows >= 1 and table_schema = 'yourDatabaseName';

為您的資料庫實作上述語法。這裡，我們的資料庫是「test」。查詢如下 -

mysql> select table_type,table_name ,table_schema from information_schema.tables
−> where table_rows >= 1 and table_schema = 'test';

以下是顯示資料庫「test」中非空表的輸出 -
