I have a table called USERS and a table called ADDRESSES , as well

  • 0

I have a table called USERS and a table called ADDRESSES, as well as an ADDRESS_TYPE table. Each user can have multiple addresses.

SELECT *
FROM USER
INNER JOIN address ON address.userId = user.userId
INNER JOIN address_type ON address_type.id = address.addressType
WHERE addressType = 4 
    OR primaryAddress = 1

I want to join the address table to the user table if they have an addressType of 4, but if their addressType is NOT 4 it should pull in the address that is marked as the primary. Basically the problem is that I need to group the query so that each user only gets 1 row, while having logic = “if addressType = 4, join this address, else if primaryAddress = 1, join this other address”.

Hope this makes sense, very grateful for any help.

Edit: These are the tables I am dealing with:
