2. how do i give the ability to the user in formview to enter true/false?

Answer 1

As the others said, you can use BIT datatype.

However, be warned that if you put BIT into a table, and you want only binary values, disable NULL.

If you allow NULL in a bit field it will actually be trinary and allow three values.
