Home -> Community -> Mailing Lists -> Oracle-L -> RE: slightly OT: visual c++ and null values
Pro*C has indicator variables.
MFC's ODBC classes have IsNull functions.
Both methods add an extra step to the code to check for null, so it is a pain to implement (and a major pain if all the columns are nullable), but it is doable.

hello!
our developers here are requesting that I put defaults (' ' for
chars/varchars, 0 for numbers, etc) in place instead of nulls in all
columns that would supposedly allow null values...
they are using visual c++ and they say that they cannot make visual c++
retreive null values...
i am very hesitant in implementing this...
i have no knowledge whatsoever of visual c++ and don't know if this is
true...
i'd like to know if anyone had encountered this same problem before? or maybe someone can tell me if there is any truth to what our developers are saying...

thanks =)
