|Oracle® Call Interface Programmer's Guide

|PDF · Mobi · ePub|
Oracle Call Interface (OCI) is an application programming interface (API) that lets applications written in C or C++ interact with Oracle Database. OCI gives your programs the capability to perform the full range of database operations that are possible with Oracle Database, including SQL statement processing and object manipulation.
This guide is intended for programmers developing new applications or converting existing applications to run in the Oracle environment. This comprehensive treatment of OCI will also be valuable to systems analysts, project managers, and others interested in the development of database applications.
This guide assumes that you have a working knowledge of application programming using C. Readers should also be familiar with the use of Structured Query Language (SQL) to access information in relational database systems. In addition, some sections of this guide also assume a knowledge of the basic concepts of object-oriented programming.
For information about basic Oracle concepts, see Oracle Database Concepts.
For information about the differences between the Standard Edition and the Enterprise Edition and all the features and options that are available to you, see Oracle Database New Features Guide.

The Oracle Call Interface Programmer's Guide does not contain all information that describes the features and functionality of OCI in the Standard Edition and the Enterprise Edition products.
For C++ programmers, the Oracle C++ Call Interface provides OCI functionality for C++ programs and lets you manipulate database objects (of user-defined types) as C++ objects.
