Sybase Open Client Support

Sybase Open Client provides customer applications, third-party products, and other Sybase products with the interfaces needed to communicate with SAP Sybase IQ and other Open Servers.

When to use Open Client

You should consider using the Open Client interface if you are concerned with Adaptive Server Enterprise compatibility or if you are using other Sybase products that support the Open Client interface.

Open Client applications

You can develop applications in C or C++, and then connect those applications to SAP Sybase IQ using the Open Client API. Other Sybase applications, such as OmniConnect, use Open Client. The Open Client API is also supported by Sybase Adaptive Server Enterprise.

This section describes the Open Client programming interface for SAP Sybase IQ. The primary documentation for Sybase Open Client application development is the Sybase Open Client documentation, available from SAP.

What You Need to Build Open Client Applications

You may have these components present as part of your installation of other Sybase products or you can optionally install these libraries with SAP Sybase IQ, subject to the terms of your license agreement.
