Access to Web Services Using Web Clients

SAP Sybase IQ can be used as a web client to access web services hosted by an SAP Sybase IQ web server or third party web servers such as Apache or IIS.

In addition to using SAP Sybase IQ as a web client, SAP Sybase IQ web services provide client applications with an alternative to traditional interfaces, such as JDBC and ODBC. They are easily deployed because additional components are not needed, and can be accessed from multi-platform client applications written in a variety of languages, including scripting languages — such as Perl and Python.

• Quick Start to Using SAP Sybase IQ As a Web Client
  This section illustrates how to use SAP Sybase IQ as a web client application to connect to an SAP Sybase IQ HTTP server and access a general HTTP web service. It does not illustrate SAP Sybase IQ web client capabilities to a full extent. Many SAP Sybase IQ web client features are available that are beyond the scope of this topic.
• Quick Start to Accessing an SAP Sybase IQ HTTP Web Server
  This section illustrates how to access an SAP Sybase IQ HTTP web server using two different types of client application — Python and C#.

• Web Client Application Development
  SAP Sybase IQ databases can act as web client applications to access SAP Sybase IQ hosted web services or web services hosted on third party web servers. SAP Sybase IQ web client applications are created by writing stored procedures and functions using configuration clauses, such as the URL clause that specifies the web service target endpoint. Web client procedures do not have a body, but in every other way are used as any other stored procedure. When called, a web client procedure makes an outbound HTTP or SOAP request. A web client procedure is restricted from making an outbound HTTP request to itself; it cannot call a localhost SAP Sybase IQ web service running on the same database.
• HTTP and SOAP Request Structures
  All parameters to a function or procedure, unless used during parameter substitution, are passed as part of the web service request. The format in which they are passed depends on the type of the web service request.
• How to Log Web Client Requests
  Web service client information, including HTTP requests and transport data, can be logged to the web service client log file. The web service client log file can be specified with the -zoc server option or by using the sa_server_option system procedure:
