[Mapserver-users] query by record num

[Nikolai Vladychevski]

Hello, 

I have a shapefiles with lines or polygons and I want to query an item by 
its sequencial number in the shapefile, for example, I want to select the 
polygon number 239 on the map. I don't have any unique identifier in the DBF 
file. Can be a shape queried by its record number? If so how? I supose I 
need to use queryByAttributes(string qitem, string qstring, int mode) call, 
but how do I tell it to search by record number? 

Thanks in advance
Nikolai
