法学如何使用列显示 MySQL 表名称？
你可以使用 INFORMATION_SCHEMA.COLUMNS 表使用列显示 MySQL 表名称。语法如下 −
SELECT DISTINCT TABLE_NAME,Column_Name FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_SCHEMA = 'yourDatabaseName';
在此，我们有一个包含表的名为“sample”的数据库。显示表名称和列名称的查询如下 −
mysql> SELECT DISTINCT TABLE_NAME,Column_Name -> FROM INFORMATION_SCHEMA.COLUMNS -> WHERE TABLE_SCHEMA = 'sample';
输出
