question on where clause

Hello:

I've come across a where clause that I haven't seen before.

Select

     table1.column1,
     table2.column2
from
     table1,
     table2
where
     1=1
   and
     table1.column3 = table2.column3

What puzzles me is the first line in the where clause, "1 = 1"

This is always true so why put it in? What purpose does is serve?

Thanks
