pyodbc, pymssql, and adodbapi each use binary modules, so they would
require some (unknown amount of) conversion to work with IronPython.
I wrapped a module around the IPCE adaptor module to meet (more of)
the DBAPI 2.0 module level requirements, and duplicated the pyodbc
code in databases/mssql.py to use my module.
That got me an error on the Table('users', metadata, ... line from the
tutorial:

This error looks like it might be due to a difference in the type
systems between C-Python and IronPython, previously reported as
http://www.codeplex.com/IronPython/WorkItem/View.aspx?WorkItemId=7594
That IronPython work item is currently scheduled for the 2.0 alpha 2
release. Note that the community can vote for problems to be fixed on
the Codeplex site.
Here is my wrapper module, which I called ipodbc.py:
import dbapi
import odbc as db
dbapi._load_type(db.assembly,db.typename)
def connect(connectStr):
return = db.connect(connectStr)
apilevel = '2.0'
threadsafety = 0
paramstyle = 'qmark'
