If you are working with VFP9 try a 'left outer join' like in this template
SELECT A.Id, B1.Type as Typ1, NVL(B2.Type, " ") as Typ2;
FROM A INNER JOIN B b1 ON a.id = b1.parent AND b1.type ="a" ;
LEFT OUTER JOIN B b2 ON a.id = b2.parent AND b2.type = "b"
here above you will have a line if there is a line in B for typ1 even if
there is no line for typ2. I have written the condition on b1.type and
b2.type in the JOIN clause instead of the WHERE clause. It is not the
same thing. If conditions are in the WHERE claus, VFP will first try to
build a set of record with the join and then filter it with the WHERE.
I hope I am clear !
