[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-4580) Possible Sybase bug causes AssertionFailure in QueryByExampleTest

Possible Sybase bug causes AssertionFailure in QueryByExampleTest ----------------------------------------------------------------- Key: HHH-4580 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4580 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.2.4.sp1, 3.3.2, 3.5.0.Beta-1, 3.5.0-Beta-2 Environment: sybase 15 Reporter: Strong Liu Assignee: Steve Ebersole Test QueryByExampleTest.testJunctionNotExpressionQBE fails due to a possible bug in Sybase 15. The same test passes for Sybase 12.5. The test expects two records as a result for a query, but it gets 3. After some debugging with the query that Hibernate generated, I end up with these two simpler ones: select id from Componentizable where not (name like ? and subName1 like ?) select id from Componentizable where not (name like 'hibernate' and subName1 like 'ope%') The first one returns three records, while the second returns two. The interesting part is that if I replace the first parameter in the first query by a hardcoded value ("hibernate"), it still returns 3 records. That means that the problem is probably with the binding of JDBC parameters containing a wildcard % .
