Question

I am trying to select a tshirts which the user has not voted on yet (from another table “votes”)

“submissions” is the table with the tshirts

“votes” is the table that holds votes

“votes” structure is: ID, TEE, USER (where votes.tee == submissions.id)

This is the mysql statement I am trying:

SELECT 
  submissions.name,
  submissions.id,
  submissions.uploader,
  submissions.image_vote
 FROM 
  submissions,votes 
 WHERE 
  submissions.date_voted IS NOT NULL AND
  submissions.id NOT IN (SELECT tee FROM votes WHERE tee=submissions.id AND user='3')
 LIMIT 1  

Now from what I understand I cannot use “tee=submissions.id” because it is from a query outside of this sub query. So how can I pass the sub query the ID of the tshirt I am checking?

Thank you.

Did you try this:

SELECT 
  submissions.name,
  submissions.id,
  submissions.uploader,
  submissions.image_vote
 FROM 
  submissions,votes 
 WHERE 
  submissions.date_voted IS NOT NULL AND
  submissions.id NOT IN (SELECT tee FROM votes WHERE user='3')
 LIMIT 1 

Maybe not the most efficient, but as close to your idea as possible.
