[Bug]: TDS Column MetaData is different and looks incorrect

[dcowan-e-courier]

What happened?

I have noticed ADO.net rowsets do not behave correctly when trying to do batch operations. Also inspecting rowset xml differs between mssql and babelfish. Key columns are not identified as key columns. I believe this is due to the TDS metadata for columns.

For a query like

select RateGroupID,Description from RateGroup with (readuncommitted) order by Description

I get TDS data like so

For babelfish 3.4 I get this result

Notice many flags are missing. Also notice the Identity Flag is always true even for non identity columns. Also Updateable is false for babelfish

ADO.net connections seem to rely heavily on the column metadata and its correctness.
