Question

i have 2 tables:

table1

id message       user
1  testing       23
2  testing again 44
3  test..        23
5  lol           12
6  test..        6

and

table2

id user friend
1  23   44
2  23   6
3  19   12
4  23   32
5  23   76
6  23   89

i am trying to get the messages of all users that are friends with 23 including 23

like:

id message       user   id user friend
1  testing       23     n  n    n
2  testing again 44     1  23   44
3  test..        23     n  n    n
6  test..        6      2  23   6

we can see that 12 is missing because he is not friend with 23 but only with 19

i’ve got this

SELECT * 
FROM table1 AS w
INNER JOIN table1 AS f ON w.user = f.friend 
WHERE (w.user = 23) 

but in case 23 has messages but no friends it will return null and also this will return other friends of 23 like 76 and 89 that have no messages..

🙂 confused?

any ideas?

thanks

Try this:

SELECT 
    table1.*, 
    table2.* 
FROM 
    table2 
        RIGHT JOIN table2 
        ON table2.friend = table1.user 
WEHRE 
    table2.user = 23
