Hi All,
 
I have a shapefile more than 500MB, to speed up the performance, I've made a TILEINDEX shapefile and use it in mapfile instead of the original shapefile. Now I want to make a query on this layer, but using the attributes in the DBF file of the original shapefile. Is it possible to make this query like that?
 
thanks for any hints.
 
Regards
 
Zhonghai
