[Mapserver-users] OGR Layer with SQL

[Blaine Hackett]

Thanks Frank. I will do that. One other thing.  I am
trying to send variables via the url so that people
can input a date range from the webpage.

So, I am not using an .ovf file.  I have the OGR
connection syntax in the map file(I have that working
by the way). 

The question is, would that make any difference?

Thanks again
Blaine
