Question

I was wondering if there was an easy way in SQL to convert an integer to its binary representation and then store it as a varchar.

For example 5 would be converted to ‘101’ and stored as a varchar.

Answer 1

Following could be coded into a function. You would need to trim off leading zeros to meet requirements of your question.

declare @intvalue int set @intvalue=5  declare @vsresult varchar(64) declare @inti int select @inti = 64, @vsresult = '' while @inti>0   begin     select @vsresult=convert(char(1), @intvalue % 2)+@vsresult     select @intvalue = convert(int, (@intvalue / 2)), @inti=@inti-1   end select @vsresult
