[SwaJime]: Ran into an interesting piece of code today ...
[SwaJime]: select name,status, status2 from __ where status & status < 13 and status2 & 16 <> 16
[SwaJime]: I'm thinking that looks messed up. Sorry for OT ... but I know y'all are smart :-)
[SwaJime]: I expected items to not be selected if status was 0 ... but they were selected
[SwaJime]: any thoughts?
