One can "SELECT" any computation and get a value.It doesn't show a bitwise operator being used against an INT or BIT column, as I further elaborated.
I assumed a certain level of familiarity with databases and provided enough info to answer your main question: "what are the available bit string operators?". That you can apply these operator to either constants or columns was knowledge I took for granted.
From what I can tell so far, i need to extract and compare a substring for the (reverse) index of the particular bit I want to filter on.
B'1001' is typed bit(4)...
The only requirement with a WHERE clause is that the computation must result in a boolean. My example SELECT computation does just that. It uses "varbit" for convenience but INT can be CAST() to BIT and the operators themselves should operate on any of the BIT variants.
What you want is the "bit-wise AND" operator and the equality operator, both of which you were shown.
I'd suggest you put forth your own example, filling in pseudo-code where needed, if you wish for more specific advice.
