> This may not be a new bug , but it started happening to me with the recent upgrades of Cayenne 4.0 that features more consistent escaping of the LIKE special chars. If LIKE ("likeIgnoreCase" actually, but I think LIKE works similarly) is combined with another qualifier clause, Cayenne wraps it in  parenthesis, leaving ESCAPE clause out of them:
> SELECT t0.* FROM mytable t0 WHERE (t0.COLUMN1 = ?) AND (UPPER(t0.COLUMN2) LIKE UPPER(?)) ESCAPE '!' 
> [bind: 1->COLUMN1:68, 2->COLUMN2:'%test!_test%']
> This results in an exception on MySQL. Will likely fail on other DBs as well. Will need to translate ESCAPE properly.
