创建一个 WHERE OR IN postgres

Question

现在我有查询

DELETE FROM connections
WHERE "user_b_id" IN
(SELECT "id"
FROM   "users"
WHERE  'dharness.student@gmail.com'="email")

但我真正想要的是

WHERE "user_b_id" OR "user_a_id" IN ...

但我不知道该怎么做。有运营商吗？

Answer 1

如果 users.email 是唯一的你可以写

WHERE (SELECT id FROM users 
       WHERE email = 'dharness.student@gmail.com') 
   IN (user_b_id , user_a_id)

Create a WHERE OR IN postgres
