Hi, me again.
I'm having fun here, but here's another question for you.
Could someone please give me an example of a join where one of the fields is
missing - I think reading from the docs that this is an OUTER join, but I'm
having a problem with the syntax. I'm trying to create a view that pulls in
all the relevent details for a single member.
I'm still with my members table, which has links to the address table (m.madd
= a.aid), teams table (m.mteam = t.tid) and the email table (m.memail =
e.eid).
While every member has an address, and every member belongs to a team, not
everyone has an email address. My problem is that every member without an
email address gets omitted from the result set.
My view so far is:
CREATE view member_dets as select *, getphone(m.mphone) as phone, getphone(m.mfax) as fax,
getphone(m.mmobile)as mobile, getunitno(m.mid) as munitno from members m, address a, teams t,
emails e where m.madd = a.aid and m.memail = e.eid and m.mteam = t.tid;
