获取特定 MySQL 数据库中的非空表列表?

要获取特定 MySQL 数据库中的非空表列表,语法如下 -

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

登录后复制

为您的数据库实现上述语法。这里,我们的数据库是“test”。查询如下 -

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

登录后复制

以下是显示数据库“test”中非空表的输出 -
