Hannes Havel commented on HHH-5238:
-----------------------------------

Hi Gail,

I am not sure that you have undestoud my request.

In this case the string consists only numbers and representing a integer number of e.g. "10"  and this can be converted to a integer 10 and i am not speaking about to convert a text string to an integer.   

JDBC an do this easily.

Is hibernate so restricted ?

How you can establish a generalized query interface where only strings are transported and the provided service has no knowledge about the queried entities and the datatypes of the fields. 
So i think a automatic conversion of a string representing a number to the nhumber type and so on is a esential funktionality for a 
data sorage and retrieve interface.
