Hi,
I'm learning to use Postgresql's bitwise operator's as I'm interested
in building super fast search's based on user selections in web forms.
So far so good but I have just lost it a little so I thought I'd post.
Please growl at me if I'm asking on the wrong list :-)
I understand this:
SELECT 111 & 11 = 11
but not this
SELECT 1111 & 111 = 71
I was expecting the second example to be
SELECT 1111 & 111 = 111
Hmm ...
Maybe I should search on the web for some more info on how to
understand this logic.
Math was never my strongest I was always better at creative writing.
Any advice much appreciated.
Thanks
Best Regards
Rudi.
