Hi Monks
I have 3 different variables. I try to create a query based on the existence of 1,2 or all 3 of the variables. Example: 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,
Raghu
