------------------------------------

             Summary: ESCAPE clause should be included in LIKE parenthesis
                 Key: CAY-1978
                 URL: https://issues.apache.org/jira/browse/CAY-1978
             Project: Cayenne
          Issue Type: Bug
    Affects Versions: 3.2.M1
            Reporter: Andrus Adamchik
            Assignee: Andrus Adamchik
             Fix For: 4.0.M2


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.
