DB-Library API
DB-Library is a Call Level Interface that allows C applications to access Microsoft® SQL Server™ 2000. DB-Library was the original application programming interface (API) that allowed applications to access SQL Server, and remains specific to SQL Server.
The DB-Library API has not been enhanced beyond the level of SQL Server version 6.5. All DB-Library applications can work with SQL Server 2000, but only as 6.5 level clients. Features introduced in SQL Server 2000 and SQL Server version 7.0 are not supported for DB-Library applications.
SQL Server 2000 does not include a programming environment for DB-Library for Microsoft Visual Basic®. Existing DB-Library for Visual Basic applications can run against SQL Server 2000, but must be maintained using the software development tools from SQL Server version 6.5. All development of new Visual Basic applications that access SQL Server should use the Visual Basic data APIs such as Microsoft ActiveX® Data Objects (ADO) and Remote Data Objects (RDO).
