如何“將表顯示為col”之類的東西？

Question

mysql> show tables;
+----------------+
| Tables_in_test |
+----------------+
| t              |
| t2             |
| test           |
+----------------+
3 rows in set (0.00 sec)


mysql> show tables as c;
ERROR 1064 (42000): You have an error in your SQL syntax;

我想在名為c列中恢復結果，但是如您所見，這是語法錯誤...

有沒有辦法做到這一點？

Answer 1

使用information_schema：

SELECT 
 table_name AS c 
FROM 
 information_schema.tables
WHERE 
 table_schema = DATABASE()
