You need several steps.
1. Create a temporary FeatureSource for an SDF
2. Insert data into the temporary FeatureSource
3. Create a temporary LayerDefinition that points to the temporary
FeatureSource
4. Insert the temporary layer into the runtime map
5. Refresh the map
This is a generic recipe for building dynamic layers, redlining,
buffering, etc.
There exist code that does this in the "buffer" function used in the
basic AJAX viewer.
Look at the "buffer.[php,aspx,jsp]" file in:
C:\Program
Files\MapGuideOpenSource2.0\WebServerExtensions\www\mapviewer[php,net,jsp]
If you have trouble with one of the steps, please ask again.
An easier way of dealing with it would be to create a layer that
displays ALL points.
Then use the SQL WHERE statement as the layers "filter" property.
This approach obviously has some limitations.

Hi everybody!
I hope you can help me about this problem I'm having since several days:
1) having x,y coordinates of a point, resulting from a sql query, how
can I display it at runtime on the map?
2) having x,y coordinates of a sequence of points, resulting from a
sql query, how can I display them at runtime on the map?
I really hope you can help me with that
Thank you very much in advance
Carmelo
