RPGlib

librpg - An other Postgres-C++ -Interface

Purpose and Advocacy

The errorhandling makes the programms ugly and heavy to understand. Thus I decided to use the try-catch-machanism.
We want a simple and efficient Interface and to use the C++-Mechanisms only when a real advantage is expected.

At this time, it is not a complete interface. Like it is in open-source Projects: Better ideas are alwas wellcome.

The Classes

PgException: the exception for Postgreserrors
PgConnection: convienience-Wrapper
PgTransaction: automatic ROLLBACK when a exception is thrown
PgResultHandle: automatic Management for PGresult

Installation and Application

Download it librpg.tgz

Copy rpglib.h to the Postgres- includes and the librpg.so.* to the postgres-libraries. In the source:

#include<rpglib.h>

in the Makefile:

mdynamisch: main.cc librpg.so rpglib.h
        $(CC) -o $@ -I$(POSTGRESPATH)/include -g main.cc -L$(POSTGRESPATH)/lib -lrpg -lpq

Further Ideas

The Postgresdatabase is a Resourcemanager. When other Resourcemanagers are involved, we need a Status "Ready for Commit".
At this time, I want first to play with a Database. Then we need a Interface of the Corba-Transactionservice ...
