Easy to use database abstraction layer

1.0.1

Introduction

Tntdb is database abstraction layer for C++.

The goals are:

• easy and safe to use
• automatic resource management
• database independent
• thin layer for best performance
• no SQL-abstraction
• use modern C++ with exceptions and STL
• support for multithreaded applications

A example, which lists the the content of a table:

#include <iostream>
#include <tntdb/connect.h>
#include <tntdb/statement.h>
#include <tntdb/row.h>

int main(int argc, char* argv[])
{
  try
  {
    tntdb::Connection conn = tntdb::connect("sqlite:mydatabase.db");

    tntdb::Statement stmt = conn.prepare(
        "select FIRST_NAME, LAST_NAME"
        "  from ADDRESS");

    for (tntdb::Statement::const_iterator cur = stmt.begin();
         cur != stmt.end(); ++cur)
    {
      tntdb::Row row = *cur;
      std::cout << row[0].getString() << '\t' << row[1].getString() << std::endl;
    }
  }
  catch (const std::exception& e)
  {
    std::cerr << e.what() << std::endl;
  }
}

Example: modify data:

#include <iostream>
#include <tntdb/connect.h>
#include <tntdb/statement.h>
#include <tntdb/row.h>

int main(int argc, char* argv[])
{
  try
  {
    tntdb::Connection conn = tntdb::connect("sqlite:mydatabase.db");

    tntdb::Transaction trans;  // start a transaction here

    tntdb::Statement stmt = conn.prepare(
        "insert into ADDRESS (ID, FIRST_NAME, LAST_NAME)"
        "  values (:id, :firstName, :lastName)");

    stmt.set("id", 34)
        .set("firstName", "Tommi")
        .set("lastName", "Makitalo")
        .execute();

    stmt.set("id", 35)
        .set("firstName", "Linus")
        .set("lastName", "Torvalds")
        .execute();

    // if no explicit commit is executed, then rollback is done
    trans.commit();
  }
  catch (const std::exception& e)
  {
    std::cerr << e.what() << std::endl;
  }
}
