"if a number larger than one is used, it is converted to one."

I thought the actual explanation was that anything other than 0 (false) is treated as true and hence is stored as 1. So a number larger than 1 becomes 1, but so does any number less than 1, apart from 0.

OK. I am in the 17% who got it wrong - I replied "Error". And now I know. But will somebody kindly explain why BIT is treated any differently to TINYINT, SMALLINT, INT, etc. It is, after all, only a type that has a range of valid values. If the others report an overflow error when I try to assign values outside their permitted range, why not BIT also?

Here's a slightly better reference
http://msdn.microsoft.com/en-us/library/ms191530(SQL.90).aspx#_bit

"Converting to bit promotes any nonzero value to 1"
