21.4.5.1. MySQL Connector/C++ Connecting to MySQL

A connection to MySQL is established by retrieving an instance of sql::Connection from a sql::mysql::MySQL_Driver object. A sql::mysql::MySQL_Driver object is returned by sql::mysql::MySQL_Driver::get_mysql_driver_instance().

sql::mysql::MySQL_Driver *driver;
sql::Connection *con;

driver = sql::mysql::MySQL_Driver::get_mysql_driver_instance();
con = driver->connect("tcp://127.0.0.1:3306", "user", "password");

delete con;

Make sure that you free the sql::Connection object as soon as you do not need it any more. But do not explicitly free the connector object!
