BigDecimalHandler provides wrappers for JDBC API methods which use BigDecimal.
When writing tests which use BigDecimal, the methods in this class can be called
instead of directly calling JDBC methods.
Run a test that compares itself to a master (canon) file.
This is used to support cannon based tests that ran
under the old Derby test harness without having to convert
them.
This contains constants for all the standard SQL states as well as
for those that are specific to Derby that our tests compare against
to make sure the right error is thrown.
