I cannot guess what you wan't to do, because you mix the terms.
This is the basic structure in MapGuide:
Data Source (eg, MsSQL) -> FeatureSource (a connection to the
datasource, created in Studio) -> LayerDefinition (styling of a table in
the FeatureSource, created in Studio) -> MapDefinition (a collection of
layers, created in studio) -> WebLayout (toolbar setup and others,
created in Studio)
So, you cannot copy MsSql into the session repository.
You can manually run through all features in the database, and create
and SDF with the data, but this might be extremely slow.
Usually, the desired result is some subset of the data in the MsSQL
This subset, can be retrieved using a Filter, placed on the
LayerDefinition (equvalent to a SQL WHERE statement).
For further information on how to create/use filters, and how to create
a LayerDefinition in the session repo, consult the PDF version of the
Developers Guide (it should be installed along with MapGuide Open Source).
If you get stuck in the dev guide, please referer to the step that you
got stuck at.
