Maria:

The developers need to read the PRO*C manual. What the developers need to do is to use indicator variable. These are varaiables that indicate whether the variable is NULL (or if the value was truncated when selected into).

Here is a short example.
char v_first_name[18];
short v_first_name_ind;

SELECT first_name
INTO v_first_name:v_first_name_ind
FROM emp
WHERE emplid = :v_emplid:v_emplid_ind;

I forget the values for the indicator variables, but that is in the PRO*C manual.

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...
