CS-TDS-VERSION defines the version of the Tabular Data Stream (TDS) protocol that the connection is using.
Because CS-TDS-VERSION is a negotiated login property, its value can change during the login process. An application can set CS-TDS-VERSION to request a TDS level before calling CTBCONNECT. In this case, when CTBCONNECT creates the connection, it looks for the requested TDS version. If the server cannot provide the requested TDS version, a new (lower) TDS version is negotiated. An application can retrieve the value of CS-TDS-VERSION after a connection is established to determine the actual version of TDS in use.
The following table lists the symbolic values that CS-TDS-VERSION can have:
