[Mysqlcppapi-main] testing result data for null

[Julian P. <jpe...@ha...>]

Hi,

How can I determine whether a ColData item is null across versions of
this library?

The test in the old version I was using was is_null(), but in a newer
version it's ism_bNull(). I would prefer to write code that can be
linked against either of these versions...


Thanks,
Julian
