DBplus

=======

**DBplus** is a C++ database interface to use the most common database

clients, such as MySQL  and PostgreSQL

.

Prerequisits

------------

  * g++ 4.6 - 

  * python 2.7 - 

  * scons 2.0 - 

  * libboost-system-dev 1.4 - 

  * libboost-test-dev 1.4 - 

  * libboost-date-time-dev 1.4 - 

  * libmysqlclient-dev 5.1 - 

  * libpq-dev 5 - 

  The project was compiled using the above compilers and libraries,

  higher versions should work well.

  To run the unit tests:

  * install mysql-server package (MySQL)

  * install postgresql package (PostgreSQL)

  * create a root user with the password "abc123" on each database server

  * create a database with the name "dbplus" on each database server

Installation

------------

  Define the compiler using the CXX environment variable, by default

  is used "g++".

    # scons

    # scons install

  For API documentation:

    # scons doc

Usage

-----

  Source code (using MySQL):

    #include 

    #include 

    #include 

    #include 

    #include 

    #include 

    #include 

    #include 

    #include 

    class Object

    {

    public:

      Object() : _id(0), _value("") {}

      void print()

      {

        std::cout << "-----------------" << std::endl;

        std::cout << "Id: "    << _id    << std::endl;

        std::cout << "Value: " << _value << std::endl;

        std::cout << "Date: "  << _date  << std::endl;

      }

      void setId(const long id)

      {

        _id = id;

      }

      void setValue(const std::string &value)

      {

        _value = value;

      }

      void setDate(const  boost::posix_time::ptime &date)

      {

        _date = date;

      }

    private:

      long _id;

      std::string _value;

      boost::posix_time::ptime _date;

    };

    int main()

    {

      dbplus::MySql mysql;

      mysql.connect("dbplus", "root", "abc123", "127.0.0.1");

      std::string sql = "SELECT id, value, date FROM test";

      std::shared_ptr result = 

        std::dynamic_pointer_cast(mysql.execute(sql));

      std::list objects = 

        result->getAll([](std::map row) {

          Object object;

          object.setId(boost::any_cast(row["id"]));

          object.setValue(boost::any_cast(row["value"]));

          object.setDate(boost::any_cast(row["date"]));

          return object;

        });

      for (Object object: objects) {

        object.print();

      }

    }

  Compiling:

    g++ -std=c++0x test.cpp -o test -ldbplus -lboost_date_time -lmysqlclient

  Output:

    -----------------

    Id: 1

    Value: This is a test
