----------------------------
Key: CAY-908
URL: https://issues.apache.org/cayenne/browse/CAY-908
Project: Cayenne
Issue Type: Bug
Components: Cayenne Core Library
Affects Versions: 3.0
Reporter: Andrus Adamchik
Assignee: Andrus Adamchik
Priority: Minor
When testing on sybase, syntax (1) generates an exception below. Syntax (2),
with only one column in subselect, works.
(1) SELECT DISTINCT t0.PAINTING_TITLE AS PAINTING_TITLE, t0.ARTIST_ID AS
ARTIST_ID, t0.PAINTING_DESCRIPTION AS PAINTING_DESCRIPTION, t0.ESTIMATED_PRICE
AS ESTIMATED_PRICE, t0.GALLERY_ID AS GALLERY_ID, t0.PAINTING_ID AS PAINTING_ID
FROM PAINTING t0
WHERE EXISTS
(SELECT DISTINCT t1.PAINTING_TITLE, t1.ARTIST_ID, t1.PAINTING_DESCRIPTION,
t1.ESTIMATED_PRICE, t1.GALLERY_ID, t1.PAINTING_ID FROM PAINTING t1
WHERE t1.PAINTING_TITLE = t0.PAINTING_TITLE AND t0.ESTIMATED_PRICE <>
t1.ESTIMATED_PRICE)
(2) SELECT DISTINCT t0.PAINTING_TITLE AS PAINTING_TITLE, t0.ARTIST_ID AS
ARTIST_ID, t0.PAINTING_DESCRIPTION AS PAINTING_DESCRIPTION, t0.ESTIMATED_PRICE
AS ESTIMATED_PRICE, t0.GALLERY_ID AS GALLERY_ID, t0.PAINTING_ID AS PAINTING_ID
FROM PAINTING t0
WHERE EXISTS
(SELECT DISTINCT t1.PAINTING_ID FROM PAINTING t1
WHERE t1.PAINTING_TITLE = t0.PAINTING_TITLE AND t0.ESTIMATED_PRICE <>
t1.ESTIMATED_PRICE)
