Hi, I have to say that I am not convinced that you can/should be doing a "Like" on an Integer field. I'm fairly certain that on many databases you can only do Like on a VARCHAR field. I'm not sure that it makes any logical sense to do Like on anything but a VARCHAR, let alone whether OJB should support it.
