[mapserver-users] NQuery problem

[subha at gslab.com]

Hi,

I do get the WMS layer alone giving me the points on the map.
My tablename is not really "tablename".Changed it for privacy
reasons.That's all.

So, if my statement looks like what you have mentioned,how would the
nquery request be?

Thanks a lot for your help.
