Okay, I know this is uber-geek so no need to mention that in the comments 
But I was searching for an easy way to prevent division by zero in a division operation in a (MS)SQL SELECT statement, and this popped out as a great way to do so. Use at your own risk of also being branded a geek, and being forced into a world of Star Trek collectables 
ISNULL( NULLIF( your_field, 0 ), 1 )
Sexy Sql Tip
Monsieur Keebler has a quick little post on avoiding divide by zero errors in Sql.
Coupled with some fairly… warm and fuzzy … imagery of the foxy Megan Fox.
Have a read (and look) over @ keebler.net

I for one welcome our non-divisible-by-zero overlords
I hear when you divide by zero, God kills a kitten.
I heard that when you divide by zero the client kills a developer. I, however, have proof against this. You know what I’m talking about.
Bill for another 8 hours?
so beatifull
DECLARE @x VARCHAR(10)
SET @x = ”
SELECT @x/0 –divide-by-zero error
SELECT ISNULL( NULLIF( @x, 0 ), 1 )/0 –ditto!!!
