22.5.6. MySQL Connector/C++ Tutorials

Here are some tutorials on using MySQL Connector/C++. You should also have a look at the examples which can be found in the following section Section 22.5.5, “MySQL Connector/C++ Getting Started: Usage Examples”.

Setting up the World database for use in the tutorials

These tutorials primarily use the World database, so you need to have that installed. You can download the World database, and documentation on how to install it, from the MySQL Documentation page - look for the section called “Example Databases”.

Tutorial framework code

Rather than repeating the same code, a framework is given here. You can reuse this framework with all the tutorials unless otherwise stated. This boiler plate code can then simply be reused for each tutorial.

The framework code is given here:

#include <stdlib.h>
#include <iostream>
#include <sstream>
#include <stdexcept>
#include "mysql_connection.h"
#include <cppconn/driver.h>
#include <cppconn/exception.h>
#include <cppconn/resultset.h>
#include <cppconn/statement.h>
#include <cppconn/prepared_statement.h>
#define EXAMPLE_HOST "localhost"
#define EXAMPLE_USER "root"
#define EXAMPLE_PASS ""
#define EXAMPLE_DB "world"
using namespace std;
int main(int argc, const char **argv)

    string url(argc >= 2 ? argv[1] : EXAMPLE_HOST);
    const string user(argc >= 3 ? argv[2] : EXAMPLE_USER);
    const string pass(argc >= 4 ? argv[3] : EXAMPLE_PASS);
    const string database(argc >= 5 ? argv[4] : EXAMPLE_DB);

    cout << "Connector/C++ tutorial framework..." << endl;
    cout << endl;

    try {
    } catch (sql::SQLException &e) {
          The MySQL Connector/C++ throws three different exceptions:
          - sql::MethodNotImplementedException (derived from sql::SQLException)
          - sql::InvalidArgumentException (derived from sql::SQLException)
          - sql::SQLException (derived from std::runtime_error)
        cout << "# ERR: SQLException in " << __FILE__;
        cout << "(" << __FUNCTION__ << ") on line " << __LINE__ << endl;
        /* Use what() (derived from std::runtime_error) to fetch the error message */
        cout << "# ERR: " << e.what();
        cout << " (MySQL error code: " << e.getErrorCode();
        cout << ", SQLState: " << e.getSQLState() << " )" << endl;
        return EXIT_FAILURE;
    cout << "Done." << endl;
    return EXIT_SUCCESS;

To compile and run the framework

First, copy and paste the framework code to a file such as frmwk.cpp. Edit the #define statements to reflect your connection details (server, user, password, database).

To compile the framework, for example on Mac OS X, type:

shell> g++ -o frmwk -I/usr/local/include -I/usr/local/include/cppconn -lmysqlcppconn frmwk.cpp

To run the framework, enter the following:

shell> ./frmwk

You will see a simple message. You are now ready to continue to the tutorials.
