database design help (mysql)
i need to set up a rather complicated system using mysql. my idea is sound, but the implementation is quite tricky.. i was wondering if anybody knew some kind of trick or knows how to deal with a problem like this..i plan on using two indexes to organize the data. both will be set to AUTO_INCREMENT, except that one has to depend on the other. that might sound a bit confusing.. so heres a little example:
COL1 COL2
1 1
1 2
1 3
2 1
2 2
3 1
3 2
in general, each item in COL1 has a unique value in COL2, and both are set to auto_increment. i can't figure out a way to implement this, though.
if you still have no idea what i'm saying, reply to this and i'll get into the specifics.
please help. thanks!
