Clive Stellings updated PHOENIX-4639:
-------------------------------------
Description: When attempting to use a UDF the code for evaluate never runs
if the parameter for the UDF is null. I wrote a function called isnull that is
attempting to emulate the same function as in Mysql but when I enter null e.g.
isnull(null) it returns with an empty value and when I check if the evaluate
method actually runs, it never enters the method. (was: When attempting to use

empty value and when I check if the eva;iate method actually runs, it never
