Hi Jeremy, thanks for your instant feedback. I directly tried your suggestion and now it works. So there is a bug in the cache implementation with regard to Type Mappings. And its not a DB2 thingy because i am using MySQL ;-)
if you need more infos in the error case, i am willing to help if you want.... I would like to see this solved because disabling the cache means decreasing the performance somehow right? --- regards Marc Logemann http://www.logemann.org http://www.logentis.de Am 02.03.2011 um 17:31 schrieb Jeremy Bauer: > Hi Marc, > > I'm wondering if this isn't caused by an inconsistent parameter type mapping > as a result of using the QuerySQLCache.
