Hi,
I have three tables, say "parent", "child" and "grandchild", and want to
do an inner join on parent and child, and left outer join on child &
grandchild. So, all parents with children, and all grandchildren if they
exist.
However, I can't accomplish this in a single query, and have been
staring at it long enough to need some input!
I want to do something like: -
selected=db(db.parent.ALL, db.child.ALL, db.grandchild.ALL,
join=db.child.on(db.child.parent_id==db.parent.id),
left=db.grandchild.on(db.child.id==db.grandchild.child_id)
)
...which isn't right but hopefully gets across what I'm after.
How should I be combining the two types of join?
