SQLColumns extra columns #52

Closed jduo closed 7 years ago

jduo commented 7 years ago

Under SQLColumns, there are several new columns added when running an ODBC 4.0 environment. Can these columns also be exposed in other ODBC versions, and just get treated as custom columns in those cases?

It's fine for drivers to expose these as custom columns in pre-ODBC 4.0 environments, but clients can't assume the semantics of these columns until 4.0.

Added the ability to support new columns without reporting 4.x in catalog functions to section 5.2, ODBC 3.x Drivers.
