This section provides abstracts for and links to the technical documents in the Windows Protocols documentation set that are currently released as preview PDF versions. These documents are in the process of being created or updated for either new product versions or significant product updates.

Microsoft may publish technical documents as preview (also called pre-release or preliminary) versions for community review and feedback. Not every technical document is published for preview, and each document’s preview period may vary. After the preview period is completed, the technical document is published to its appropriate location in the Microsoft Open Specifications Library.

To provide feedback or ask questions about a preview version of a technical document, you can use the Open Specifications forums.

Latest release

[MS-TDS-Diff]: Tabular Data Stream Protocol

Specifies the Tabular Data Stream (TDS) protocol versions 7 and 8, which is an application layer request/response protocol that facilitates interaction with a database server and provides for authentication and channel encryption; specification of requests in SQL (including Bulk Insert); invocation of a stored procedure, also known as a Remote Procedure Call (RPC); returning of data; and Transaction Manager Requests.

This document has been updated to define the difference between the TDS 7.x version family, in which encryption is optional and negotiated in the TDS layer, and the new TDS 8.0 version, in which encryption is mandatory and handled in the lower layer before TDS begins functioning.
