Select twice from two different columns in the same row and the same table

[Udyret]

I got some tables I want to join. I know very basicly how to join tables, but I'm no good at it and I don't have much experience with it...

I have two tables:

_________________________________
| meeting |
-----------------------------------------------------------
| meetingid | person1id | person2id | other |
-----------------------------------------------------------

______________
| people |
-------------------------
| peopleid | name |
-------------------------


I have the meetingid, and I want to select the meetingid, name of the person1id, name of the person2id and other.

If it makes any difference, it's gonna be used alongside php. :)

Thanks in advance!

Hey.

You can JOIN the `people` table with the `meeting` table twice; once for each person you need to join.

For example:

SELECT
    m.meeting_id, m.other,
    p1.id AS 'p1_id', p1.name AS 'p1_name',
    p2.id AS 'p2_id', p2.name AS 'p2_name'
FROM meeting AS m
LEFT JOIN people AS p1
    ON m.person1_id = p1.people_id
LEFT JOIN people AS p2
    ON m.person2_id = p2.people_id
WHERE 
    m.meeting_id = 1; -- or something

P.S.
As a general rule, it is best to avoid using plural words for table names. Meaning; rather than name the table 'people', name it 'person'. That way you can avoid awkward names like 'peopleid' (Which makes little sense, really)

Thanks, yeah, the names etc isn't the exact stuff that I actually use. Just something to make the example easy! But thanks to you, it now works and I've got more insight on how to write mysql queries with join.
