Hi,

declare @b bit

select @b = 1 -- 1 is true

or select @b = 0 -- 0 is false

for True/False bit is best

thanks, where would i declare that 1 is true and 0 is false? and how exactly would it look?

thanks
1 is true and 0 is false. This is normal behaviour. Historically -1 is true because it is a bit mask showing all bits as 1 including the sign.
You could equally have a varchar field that says 'true' or 'false'. It depends how you represent the value in your database on the front end asp.net code. In this case though a bit field is your best choice of datatype.

short but to the point
