The MSSQL dialect will work with three different available drivers:
-* *pymssql* - http://pymssql.sourceforge.net/
-
* *pyodbc* - http://pyodbc.sourceforge.net/. This is the recommeded
driver.
+* *pymssql* - http://pymssql.sourceforge.net/
+
* *adodbapi* - http://adodbapi.sourceforge.net/
Drivers are loaded in the order listed above based on availability.
+
+If you need to load a specific driver pass ``module_name`` when
+creating the engine::
+
+ engine = create_engine('mssql://dsn', module_name='pymssql')
+
+``module_name`` currently accepts: ``pyodbc``, ``pymssql``, and
+``adodbapi``.
+
Currently the pyodbc driver offers the greatest level of
compatibility.
