My two table are like

Table 1


uid     mail


1136    [email protected]
1231    [email protected]

And

Table 2

uid     rid

1136    3
1136    7
1231    5
1231    2

So I want to join these both tables and want to get the result uid where rid in table 2 is not equal to 3.

Please let me know if you doesn't understand my requirement.

  • So what's your expected output? and what have you tried? Commented Jul 23, 2013 at 9:24
  • SELECT mail FROM users LEFT JOIN users_roles ON (users.uid = users_roles.uid AND users_roles.rid <> '3'). But although uid 1136 is having rid 3 but it still came in result. I don't want that Commented Jul 23, 2013 at 9:24

select t1.uid, mail, rid
from table1 t1
join table2 t2
on t1.uid = t2.uid and t2.uid not in (select uid from table2 where rid = 3)

This is not correct as this query will also return 1136 which has rid 3. But I don't want that. I only want 1231 here as there is no rid 3 for that.
Yes i can see that let me check. Thanks
Do you have any other solution than this although it's working but very time consuming.

select t1.uid, mail, group_concat(rid) as rids
from table1 t1
