Database Engine Extended Stored Procedures - Reference

[!INCLUDE SQL Server]

Important

[!INCLUDEssNoteDepFutureAvoid] Use CLR integration instead.

The [!INCLUDEmsCoName] Extended Stored Procedure API, previously part of Open Data Services, provides a server-based application programming interface (API) for extending [!INCLUDEmsCoName] [!INCLUDEssNoVersion] functionality. The API consists of C and C++ functions and macros used to build applications.

With the emergence of newer and more powerful technologies such as CLR integration, the need for extended stored procedures has largely been replaced.

Important

You should thoroughly review the source code of extended stored procedures, and you should test the compiled DLLs before you install them on a production server. For information about security review and testing, see this Microsoft Web site.
