another sample:

Answer 1

You should consider that a "true value" is everything except 0 and not only 1. So instead of 1=1 you should write 1<>0.

Because when you will use parameter (@param <> 0) you could have some conversion issue.

The most know is Access which translate True value on control as -1 instead of 1.
