Database Engine Extended Stored Procedure Programming

重要提示：
后续版本的 Microsoft SQL Server 将删除该功能。请不要在新的开发工作中使用该功能，并尽快修改当前还在使用该功能的应用程序。 Use CLR Integration instead. For more information, see Database Engine .NET Framework Programming.

The Microsoft Extended Stored Procedure API provides a server-based application programming interface (API) for extending Microsoft SQL Server functionality. The API consists of C and C++ functions and macros used to build applications in the following categories: extended stored procedures and gateway applications.

Extended stored procedures allow you to create your own external routines in a programming language such as C. The extended stored procedures appear to users as typical stored procedures and are executed in the same way. Parameters can be passed to extended stored procedures, and they can return results and return status.

For more information and guidelines about working with extended stored procedures, see 扩展存储过程.
