Chapter 34. ECPG — Embedded SQL in C
This chapter describes the embedded SQL package for PostgreSQL. It was written by Linus Tolke (<linus@epact.se>) and Michael Meskes (<meskes@postgresql.org>). Originally it was written to work with C. It also works with C++, but it does not recognize all C++ constructs yet.
This documentation is quite incomplete. But since this interface is standardized, additional information can be found in many resources about SQL.
