Its not a good idea to to return undef explicitly.
If the routine is called in an array context you get an array with
one element ( i.e. [ undef, ] ). Better to just return; which returns
undef in a scalar context and an empty array in an array context. Makes
for dafer code.
I do not understand, perhaps I could do :
return $sth->fetchrow_hashref;
But I don't understand why return an arrey context as it will normally
returns an hashref.
bests,
