Derby INTEGER constants are signed decimal numbers, that is, legal
inputs to the java.lang.Integer.valueOf(String s) method. The radix is
always 10. Hex/octal constants won't work, as you've discovered.

Is there a way to use hex constants as integers in Derby?
I tried using X'7FFF' and I got "Comparisons between 'SMALLINT' and
'CHAR () FOR BIT DATA' are not supported".
I tried using CAST(X'7FFF' AS INTEGER) and got "Cannot convert types
CHAR () FOR BIT DATA to INTEGER".
I can of course use 32767 in this case, but for other hex values it's
a real pain to work out what it corresponds to. Or I could define a
function to convert a string hex value to an integer, but that also
seems like overkill.
Thanks,
