Value

Description

SQL Server 2000

Uses the SQL Server 2000 type system. The following comparisons will be performed when connecting to a SQL Server 2005 instance:

XML to NTEXT

UDT to VARBINARY

VARCHAR(MAX), NVARCHAR(MAX) and VARBINARY(MAX) to TEXT, NEXT and IMAGE respectively.

SQL Server 2005

Uses the SQL Server 2005 type system. No conversions are made for the current version of ADO.NET.

SQL Server 2008

Uses the SQL Server 2008 type system.

Latest

Use the latest version than this client-server pair can handle. This will automatically move forward as the client and server components are upgraded.

The TypeSystemVersion property can be used to specify a down-level version of SQL Server for applications written against that version. This avoids possible problems with incompatible types in a newer version of SQL Server that may cause the application to break. For example, setting TypeSystemVersion property to "SQL Server 2000" when connecting to a SQL Server 2005 instance exposes the 2000 type system to the application.
