I did some testing and it appears we have a bug here. I have implemented
a fix and it would be great if you could try it and confirm that it works
for you as well. Here is what you will need to do:

1. Download statement.cxx from here:

   http://codesynthesis.com/~boris/tmp/odb/statement.cxx

2. Copy it to libodb-mssql-2.2.0/odb/mssql/ (override the old file).

3. Rebuild libodb-mssql.

4. Rebuild the optimistic example.

Once this is done, the example should work.
