Embedded SQL

SQL statements embedded in a C or C++ source file are referred to as embedded SQL. A preprocessor translates these statements into calls to a runtime library. Embedded SQL is an ISO/ANSI and IBM standard.

Embedded SQL is portable to other databases and other environments, and is functionally equivalent in all operating environments. It is a comprehensive, low-level interface that provides all the functionality available in the product. Embedded SQL requires knowledge of C or C++ programming languages.
