I have a function to round a Double to a specified number of decimal places:
public static final Double derbyDouble (Double value, Integer places) {
...
}
I've declared it to Derby like so:
CREATE FUNCTION DoubleFormat (value FLOAT,
places INTEGER)
RETURNS FLOAT
PARAMETER STYLE Java
LANGUAGE Java
EXTERNAL NAME 'utils.Utils.derbyDouble';
This works if I use "double" and "int" but not Double and Integer (as in,
the methos is found & used corrrectly if I use primitive types but it isn't
found if I use the corresponding wrapper types). I've also tried Float, which
is no better.
The big difference is that, using primitive types, I can't handle nulls...
Anyone got any ideas whhat I'm doing wrong?
