C Language Support - Preprocessor2 for Embedded SQL

C Language Support

PP2 supports C in:

IBM z/OS mainframe environment

Network‑attached environment

UNIX OS

Windows

Note: Some compilers will generate C compiler warnings unless the following include statements are inserted in the Teradata supplied samples:

 #include <stdio.h>

 #include <string.h>

The C statements generated by PP2, when run in one of the above environments, are acceptable to the compilers for those environments. Execute the C precompiler by invoking module PPCMAIN.

See Chapter 2: “Connecting to the Database and Invoking PP2,” for details. For linkage details, see “Application Linking for Visual C++ on Windows” on page 226.

Every C program that requests Teradata services through embedded SQL statements requires a communications area. SQLCA is documented in “SQL Communications Area (SQLCA)” in SQL Stored Procedures and Embedded SQL (B035‑1148).
