[Cartoweb-users] how to limit and reorder queryresults

[bram]

Hi list,

I would like my queryresults to be (re)ordered according to the values 
in a column. Also I would like to restrict the number of querysresults 
according to a specific columnvalue, for instance give me only the three 
largest cities within my bbox. As far as I can see I will need to use 
the mapOverlay-plugin or the rowUnselector-tablerule. Maybe I should use 
the postgis order by-clause, but in my shape-files that won't work.  Who 
can give me a hint.

Thanks,

Bram
