|Do you know where your variables are?|
if/else optionsby imrags (Monk)
|on Aug 20, 2009 at 11:22 UTC||Need Help??|
imrags has asked for the
wisdom of the Perl Monks concerning the following question:
I have 3 different variables. I try to create a query based on the existence of 1,2 or all 3 of the variables.
However, since it is not necessary that all 3 are defined, there are many
combinations possible ($var1 exists, others don't etc.)
It depends on user as to how many variables he is looking for
Is there a way I can create a single query which takes care of existence of the three variables
without me having to use 6 if/else statements?
Thanks for the help,
