Hi folks,
I've got a little problem with a - at least I think so - correct SQL-
statement:
three tables, two referencing the 1st one
---
SELECT * FROM PRIM AS P
WHERE NOT EXISTS
(
SELECT REFID FROM REF1 WHERE REF1.REFID=P.ID
UNION
SELECT REFID FROM REF2 WHERE REF2.REFID=P.ID
);
---
chokes with "SQL error: no such column: P.ID"; as long as I do not use
a WHERE statement in the 2nd 'inner' SELECT statement, it works as
expected.
I've worked around this by creating a VIEW from the union of the two
referencing tables so I do not need the UNION in the original query.
Is this a bug or did I just not get the docs?
thanks,
-Markus
PS: sqlite really rocks & the C-API doc is very nice!
