Hi all,
I've got a table 'phones' which has an indexed key 'pid' of type int4, and a
phone number of type varchar(12).
I've then got a table 'members' which as an index key 'mid' of type int4.
Now, obviously, if each member only had one phone number, I could simply pull
it in using a join. My problem is that each member has (potentially) a voice
line 'mphone', a fax line 'mfax', and a mobile (that's a cellphone to you lot
over the pond) 'mmobile'.
How would I embelish a 'select * from members........' so that it included
the three phone numbers if they exist?
The only solution I can think of is to write a plpgsql function to do the
lookup and call that three times as part of the select, something like
select *, getphone(mphone) as phone, getphone(mfax) as fax.....
but a purely SQL solution would be nicer.
