 To facilitate working with existing pipelines, DataJoint MATLAB creates a ``TableAccessor`` property in each schema object.
 The ``TableAccessor`` property, a *virtual class generator*, is available as ``schema.v``, and allows listing and querying of the tables defined on the server without needing to create the MATLAB table definitions locally.
-For example, creating a scratch ``experiment`` schema package and querying an existing ``my_experiment.Session`` table on the server can be done as follows::
