Someone else might have a different suggestion. In your limited data set
this works:
SELECT a.id, b1.type as typ1, b2.type as typ2;
FROM b as b1 RIGHT JOIN a ;
ON a.id == b1.parent AND b1.type = 'a' ;
LEFT JOIN b as b2 ;
ON a.id == b2.parent AND b2.type = 'b'

How do I get a record for each Id even when there is no record in B for
Typ2?
TIA - Joe Yoder
* Define and load demo cursors
CREATE CURSOR A (Id I)
CREATE CURSOR B (Parent I, Type C(1))
INSERT INTO A (Id) VALUES (1)
INSERT INTO A (Id) VALUES (2)
INSERT INTO B (Parent, Type) VALUES (1, 'a')
INSERT INTO B (Parent, Type) VALUES (1, 'b')
INSERT INTO B (Parent, Type) VALUES (2, 'a')
* Retrieve the data into a single cursor
SELECT A.Id, B1.Type as Typ1, B2.Type as Typ2;
FROM A, B as B1, B as B2;
WHERE A.Id = B1.Parent AND B1.Type = 'a';
AND A.Id = B2.Parent AND B2.Type = 'b'
