ok lets say there was database that consisted of switchboard values (on or off)

column 1 (0 or 1)
column 2 (0 or 1)
column 3 (0 or 1)
column 4 (0 or 1)
column 5 (0 or 1)
column 6 (0 or 1)

now all of those are what they are (they define what is activated)

anyways right now they have their own correctponding colums, but I want to make them into one line of numbers...

so something like this

1010110

pretty much like chmod only its binary...

now which way would be best to do so. Should I make a column that is CHAR(6) or should I make a MEDIUMINT(6) colum.

Or if its possible, can a BIT column be made, so its binary


which way is better

AFAIK, they did add a BIT column type in MySQL 5, so obviously, that would be ideal. In pre-5, I would suspect the INT columns would be better suited, but you can always check the relevant [a href=\"http://dev.mysql.com/doc/refman/5.0/en/storage-requirements.html\" target=\"_blank\"]refman page[/a] that discusses column storage requirements.
Seriously... if people don't start reading this before posting, I'm going to consider not answering at all.
