Thematic mapping in MapServer

[Ma]

Dear All,

What is the best way to make more than one thematic mapping for one and
the same SHP file and what about the queering in this case? Ideas,
solutions, URL, map file?

For example I have data like this:

Country      Index-1   Index-2   Index-3  Index-...
------------------------------------------------------
Canada         0        32        54
Peru          25         0        19
Romania       78        80         0
Australia      0        10        65
UK            14        56        44
Germany       96         0        12
USA           74        21        12
Italy          0        89         0

How to make thematic mapping for all these columns in MapServer? And if
you have 50 columns or more ... ? If you add the SHP file 50 times in
the map file - what about the queering after?? Help!
