Please excuse for my lack of imagination building SQL selects with OUTER
JOINS but something's unclear for me ...
I have 3 tables, t0, t1 and t2.
Tables are:
authors (alias t0) with (id int2, name text);
books (alias t1) with (author int2, title text);
nicknames (alias t2) with (id int2, nickname text);
I want a select query with them with 2 outer joins like that
t0.id = t1.author
t0.id = t2.id
Tried :
select t0.name, t1.title, t2.nickname from authors t0 left outer JOIN
books t1 ON (t0."id"=t1."author") , authors t0 left outer join nicknames
t2 on (t0."id"=t2."id")
but it says "author table declared more than once".
with just 1 table it worked for me
Please, could you help me quickly showing me the right syntax?
I'm working to add outer joins to visual query builder in PgAccess.
