You might want to try my SQL Workbench. It has a diff command built in that can 
also be run from within a batch file (command line).

The output of the diff is an XML file that can be converted to SQL. I do not 
have an XSLT to transform the output into Derby syntax, but Postgres and Oracle 
are available.

Details are here:

The homepage is: <http://www.sql-workbench.net/>
and the sample XSLT scripts are here: http://www.sql-workbench.net/xslt.html
