选择MySQL中不包含某个列的表

Question

我试图选择所有没有名为"unique"的列的表.我可以选择使用它的所有表:

SELECT DISTINCT TABLE_NAME 
FROM INFORMATION_SCHEMA.COLUMNS
WHERE COLUMN_NAME = 'unique'
AND TABLE_SCHEMA ='database';

是否有一种简单的方法来修改SELECT语句,以便列出所有没有该列的表？这看起来很简单,但我无法弄明白,也无法在论坛上找到答案.

谢谢

select
t.*
from INFORMATION_SCHEMA.TABLES as t
    left join INFORMATION_SCHEMA.COLUMNS as c
    on c.TABLE_NAME = t.TABLE_NAME
    and c.TABLE_SCHEMA = t.TABLE_SCHEMA
    and c.COLUMN_NAME = 'unique'
where c.COLUMN_NAME is null
and t.TABLE_SCHEMA = 'database'
