sql - "subquery returns more than 1 row" error. -

-

i new web programming , i'm trying make twitter-clone. @ point, have 3 tables:

users (id, name)

  • id auto-generated id
  • name of user

tweets (id, content, user_id)

  • id auto-generated id
  • content text of tweet
  • user_id id of user made post

followers (id, user_id, following_id)

  • id auto-generated id
  • user_id user doing following
  • following_id user being followed

so, being new sql well, trying build sql statement return tweets currently-logged in user , of follows.

i tried use statement, works sometimes, other times, error says "subquery returns more 1 row". here statement:

select * tweets  user_id in ((select following_id followers user_id = 1),1) order date desc
  • i put 1 example here, id of logged-in user.

i haven't had luck statement; appreciated! thank you.

select *  tweets     user_id in (select following_id followers user_id = 1)   or user_id = 1 order date desc
