MySQL Connector/C++ Tutorials

Here are some tutorials on using MariaDB Connector/C++. Also consult the examples in , "MySQL Connector/C++ Getting Started: Usage Examples".

Setting up the World database for use in the tutorials

These tutorials refer to tables and sample data from the World database, which you can download from the MySQL Documentation page. Look for the section called "Example Databases".

Tutorial framework code

These examples all use the following framework, to avoid repeating code:

#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 {
 /* INSERT TUTORIAL CODE HERE! */
 } catch (sql::SQLException &e) {
 /*
 The MariaDB 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.
