Re: Assigning NULL value in PRO*C

Hi,

Look in the precompiler manual for indicater variables. What they basically do is fetch another value from Oracle with which you can determine null values. From the top of my head:

select comm:id from emp

if id = -1 then comm is null otherwise comm is not null.
