Hi Michael,

First of all, I would like to confirm my understanding of your issue. From
your description, I understand that you need to know how to do bitwise
comparison in the WHERE clause of a SELECT statement. If there is any
misunderstanding, please feel free to let me know.

As far as I know, bitwise operators are provided by T-SQL. Bitwise
operators are used on int, smallint, or tinyint data. The ~ (Bitwise NOT)
operator can also use bit data. All bitwise operators perform an operation
on the one or more specified integer values as translated to binary
expressions within Transact-SQL statements. To check bitwise operations,
you can convert or calculate decimal values. Here are the bitwise operators
available in T-SQL.

& (Bitwise AND)
~ (Bitwise NOT)
| (Bitwise OR)
^ (Bitwise Exclusive OR)

For more information, please check the following link. Examples are include
when you click on each operator.

HTH. If anything is unclear, please feel free to reply to the post.
