Fortunately, I only rarely need to work with MS products.

When you work under Windows, then there is ZmxODBCDA, a DA on top
of "egenix" (yes commercial) mxODBC. I do not know whether it does
have your problem, but I expect it will not.
This is not the "mxODBCDA", now under development by egenix.

When I need to interface with MSSQL (I am then on a Unix plattform),
I use either SQLRelay or the SybaseDA both over FreeTDS.
I did not yet met a "Missing.Value". This does not necessarily
mean, there is none.

The "egenix" software *IS* open source, just not without costs.
