  Hey I am new to this forum, hope i am posting my query at the right place.

  I am using uint datatype in c# however to save storage i am converting them into int and storing them in SQL as both uint and int are of 4 byte excepts that int can store -ve values. so any positive uint value which is over the range of int is converted as -ve value and is stored, while retrieving it i convert it into +ve uint value. Now my questing is, why the following two commands give different outputs, please help me understand.

  1. select convert(bigint,convert(binary(8),3000000001))

  2. DECLARE @i BIGINT = 3000000001

  select convert(bigint,convert(binary(8),@i))

  Thanks in advance.
