Question re: null
I have written a function that will return an integer based on the length
of a given field defined as text.
It seems that if the given field has not yet been populated (ie: it is
null), my function returns nothing. I have tried expressly sending back a
value as such to no avail:
int isempty(text*)
{
return (100);
}
If the text* is null, it does not return 100 though it does seem to
process the function and does not core dump. (ie: returns blank entries
with the proper number of tuples at the end). Any ideas? Thanks again.

I'm very interesting on this subject too.
Does anybody knows how to solve this question ?
I can't belive that we are the only people having problems
with NULLs. ;)
