How to extract the 1 out of a byte in sql

I need to read if a bit on position x is set.
So for instance I want to check if useragent = chrome

I try:

SQL

select UserAgent from bits where UserAgent &3 =4
I get nothing. How do I get just the chrome from bits table (00000111)?

00000001 = all
00000011 = opera
00000111 = chrome
00001111 = safari

create table bits(UserAgent binary)
insert into bits(userAgent) values (00000001)
insert into bits(userAgent) values (00000011)
insert into bits(userAgent) values (00000111)
insert into bits(userAgent) values (00001111)

Thanks,
Robert

"UserAgent &3 =4" would never be true.

Try this. I think there is logic issue with the way you are setting the bits. In my opinion thsi should be bit values

All =111
opera=001
chrome =010
safari=100

SQL

select UserAgent&4 from @bits
where UserAgent&4=4
