-------------------------------------
DataContextEJBQLConditionsTest.testArithmetics() works on MySQL, however HSQLDB
throws:
NFO: SELECT t0.PAINTING_TITLE AS ec0_0, t0.ARTIST_ID AS ec0_1,
t0.PAINTING_DESCRIPTION AS ec0_2, t0.ESTIMATED_PRICE AS ec0_3, t0.GALLERY_ID AS
ec0_4, t0.PAINTING_ID AS ec0_5 FROM PAINTING t0 WHERE t0.ESTIMATED_PRICE < ( ?
+ ( ? * ?)) [bind: 1:1, 2:-4.0, 3:-1000.0]
