displaying objects based on DBF information

[Yeewen Sat]

Hi,

I like to find out if mapserver CGI support this:

display objects based on specific DBF information?

As an example, DBF file contains a field named ObjectID. And, a map being
displayed has bunch of lines in it. When user zoom into the map, all lines
that fall inside the bounding rectangle will show up. Is there a way to tell
mapserver to draw only those lines that match the given ObjectIDs?

The same question applies to mapscript. Can I just pass these lines
ObjectIDs to some mapscript functions, and it will only plot these lines?

If mapserver cgi or mapscript does supports the above functions, can I get
some examples to get me started?

Thanks.
Yee Wen
