A big "Thank you" goes to you! That was it!
Looks like I tried with too many parentheses i.e.
/this is wrong/
SELECT FROM ...
(
(SELECT FROM ...)
UNION
(SELECT FROM ...)
) AS abc

Luke

Hi Luke..
Try this
SELECT ObjectId FROM
(SELECT f15.Form15SampleTube1RnaBarcode AS ObjectId,
f15.Form15PatientID AS PtId FROM form15 f15
WHERE f15.Form15SampleTube1RnaBarcode IN ('01D2V','01DH6')
UNION
SELECT f15.Form15SampleTube6RnaBarcode AS ObjectId,
f15.Form15PatientID AS PtId FROM form15 f15
WHERE f15.Form15SampleTube6RnaBarcode IN ('01D2V','01DH6'))as abc
Cheers :)

Subject: Query problem: UNION in subquery
Hello!
I have a problem using UNIONs inside subqueries. I have simplified my
query to make it more readable/understandable.
The question is about the right syntax.
1.
This works fine /UNION/
(SELECT f15.Form15SampleTube1RnaBarcode AS ObjectId,
f15.Form15PatientID AS PtId FROM form15 f15
WHERE f15.Form15SampleTube1RnaBarcode IN ('01D2V','01DH6'))
UNION
(SELECT f15.Form15SampleTube6RnaBarcode AS ObjectId,
f15.Form15PatientID AS PtId FROM form15 f15
WHERE f15.Form15SampleTube6RnaBarcode IN ('01D2V','01DH6'))
2.
This works fine too /subquery/:
SELECT ObjectId FROM
(SELECT f15.Form15SampleTube1RnaBarcode AS ObjectId,
f15.Form15PatientID AS PtId FROM form15 f15
WHERE f15.Form15SampleTube1RnaBarcode IN ('01D2V','01DH6')) AS
SubTable1;
3.
But when I run 1&2 combined I get in troubles. This is a query draft,
can't come up with the right syntax:
SELECT ObjectId FROM
(SELECT f15.Form15SampleTube1RnaBarcode AS ObjectId,
f15.Form15PatientID AS PtId FROM form15 f15
WHERE f15.Form15SampleTube1RnaBarcode IN ('01D2V','01DH6'))
UNION
(SELECT f15.Form15SampleTube6RnaBarcode AS ObjectId,
f15.Form15PatientID AS PtId FROM form15 f15
WHERE f15.Form15SampleTube6RnaBarcode IN ('01D2V','01DH6'))
I tried many combinations and got various syntax errors. Any ideas?
Thanks,
Luke
