Application Building Guide

DB2 API Applications

Each DB2 SDK includes sample programs that call DB2 APIs. The "Building Applications" Chapters later in the book explain how to build the sample programs for the supported compilers using DB2 API build files supplied with the DB2 SDK for that platform. You can also use the makefiles that are supplied. Both the makefiles and the build files show you the compiler options you can use. These options are defined for each platform's supported compilers in the appropriate chapter. You might need to modify the options for your environment.

The following sample program is used in this book to demonstrate the steps for building and running DB2 API applications using the supported programming languages. The steps you follow may vary, depending on your environment:

client: demonstrates the use of the following APIs: SET CLIENT, and QUERY CLIENT

Links to the source code of this program are available for the following languages:

C: client.c
C++: client.C
COBOL: client.cbl

For a detailed description of all DB2 API sample programs, see Sample Program Tables.

The source files for DB2 API sample programs, where supported, are in the appropriate programming language subdirectory of sqllib/samples (UNIX), and %DB2PATH%\samples (OS/2 and Windows 32-bit operating systems).

After you build the sample programs, they can be used as templates to create your own applications. You can build the DB2 API programs using either the makefile or the build files provided.
