[mapguide-users] Help with joining tables please

Hello, I've been fighting with this for a while and need your help.


I want to combine a few tables together and have that data available for
themeing and viewing.

Without attempting to join tables, the data loads without any problem.
However, I have not been able to get tables joined.


Using normal SQL Server 2008 "inner join tableB on tableA.location =
tableB.location" is what I'm trying to do.

Using the Autdesk Mapguide Studio, I click through, set up my joining tables
exactly as I would in SQL.

In the layer definition editor, I see the new attributes.

Before doing anything else, I export the layer as XML and test my map.  The
map viewer doesn't stop showing the busy icon, the legend labels become
question marks (?) and no data ever loads.  If I disable the layer, all the
other layers show quickly.


I've tried using the same database connection, a different database
connection, and a SDF imported from a shapefile. No method appears to work
for me.


Is there a proper way of setting up joining tables? Should I learn the XML
syntax and do it manually?


Thanks for your help,
