Hi,
Thank u very much for u r reply.
I will check it out .
My Doubt is that
1) If i create a package in mapguide maestro , connecing to the oracle how
can access the data using queries.
suppose i create a feature resource for a table data in oracle after
that i followed all the procedure and created a package successfully. If
user wants to query this table and wants to display only some of the
features on the map dynamically .How can i provide this?
If u know this plz help me
Regards,
Padmini.
