SQL query for joining information for multiple tables

Question

Here are my 3 tables :

meetings

meeting_id

first_user_id

second_user_id

users

user_id

pic_id

pictures

pic_id

pic_filename

What I need is a SQL query that results in the following record :

meeting_id

first_user_id

second_user_id

first_user_pic_filename

second_user_pic_filename

So far this is what I was thinking :

SELECT meetings.*, pics1.filename first_user_pic_filename, pics2.filename second_user_pic_filename

FROM meetings 

INNER JOIN users users1 ON meetings.first_user = user_id

INNER JOIN users users2 ON meetings.second_user = user_id

INNER JOIN pictures pics1 ON pics1.pic_id = users1.pic_id

INNER JOIN pictures pics2 ON pics2.pic_id = users2.pic_id

I'm not sure exactly what I am doing wrong. Any help would be greatly appreciated.

What I am currently getting is only a few records back, when there should be 10-15. I am wondering if there is an issue with how I am joining.

Answer 1

I suppose you should change

INNER JOIN pictures pics1 ...
INNER JOIN pictures pics2 ...

to

LEFT OUTER JOIN pictures pics1 ...
LEFT OUTER JOIN pictures pics2 ...
