Hey, I was wondering if anyone knew of an application that would be able to do the following?

I'm working on an application that supports db2, Oracle, SQL Server. My problem is that I have to run/ and test scripts against all 3 data bases every time there is a new script available (this happens an awful lot) what I was wondering if anyone knew of a tool that could read one syntax e.g db2 syntax then convert it to make it compatible to Oracle, SQL Server etc etc? or vise versa??

Any help or suggestions would be great or, if I have not explained my self then i can give a better example!
