MySQL - 为什么查询 'IN' 失败？

Question

这些查询返回正确的结果:

SHOW FULL COLUMNS FROM `users`
SHOW FULL COLUMNS FROM `teachers`

但是这个会产生错误

SHOW FULL COLUMNS IN  ('users', 'teachers')

我试过单引号、双引号、反引号和无引号，但都失败了。我做错了什么？

错误是这样的:

#1064 - You have an error in your SQL syntax; check the manual that 
corresponds to your MySQL server version for the right 
syntax to use near '('users', 'teachers')' at line 1

Answer 1

也许这给了你想要的东西？

SELECT *
  FROM information_schema.columns
 WHERE table_name IN ('users', 'teachers')
