要查找两个特定的列名称，请使用 information_schema.columns 在这里，我使用 Id 代替 columnA，使用 Name 代替 columnB -
mysql> select table_name as TableNameFromWebDatabase
-> from information_schema.columns
-> where column_name IN ('Id', 'Name')
-> group by table_name
-> having count(*) = 3;这将产生以下输出。以下是包含 Id 和 Name 列的表格 -
+--------------------------+
| TableNameFromWebDatabase |
+--------------------------+
| student |
| distinctdemo |
| secondtable |
| groupconcatenatedemo |
| indemo |
| ifnulldemo |
| demotable211 |
| demotable212 |
| demotable223 |
| demotable233 |
| demotable251 |
| demotable255 |
+--------------------------+
12 rows in set (0.25 sec)为了证明这一点，让我们检查其中一个表的描述。以下是查询 -
mysql> desc demotable233;这将产生以下输出。在这里，您可以看到我们有 Int 和 Name 列 -
+-------+-------------+------+-----+---------+----------------+
| Field | Type | Null | Key | Default | Extra |
+-------+-------------+------+-----+---------+----------------+
| Id | int(11) | NO | PRI | NULL | auto_increment |
| Name | varchar(20) | YES | | NULL | |
+-------+-------------+------+-----+---------+----------------+
2 rows in set (0.00 sec)
