MySQL Cpp Connector

First, install Cpp Connector

　　Installation Connectoor \ C ++

　　Installation libmysqlcppconn-dev

apt-cache search libmysqlcppconn-dev
sudo apt-get update
sudo apt-get install libmysqlcppconn-dev

　　After installing the visible / usr / include / header files more than three mysql_connection.h, mysql_deriver.h, mysql_error.h and folders cppconn.

 

Second, the use libmysqlcppconn-dev library database connection

 　　1. Perform a simple query

#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>
using namespace std;

int main(int argc, const char **argv)
{
	const string url="localhost";
	const string user="root";
	const string pass="zjq588";
	const string database="SRS";
	// 1.获取驱动
	sql::Driver* driver = get_driver_instance();
	// 2.连接到mysql server
	std::auto_ptr<sql::Connection> conn(driver->connect(url, user, pass));
	// 3. The selected database 
	conn-> the setSchema (Database); 
	// 4. Create the Statement 
	SQL * the Statement stmt :: = conn-> the createStatement (); 
	// 5. The execution Query 
	SQL :: = RES * the ResultSet stmt- > the executeQuery ( "SELECT * from Student;"); 
	
	// 6. The result set 
	the while (RES-> Next ()) 
	{ 
		int ID = RES-> the getInt ( "stu_id"); 
		String name = RES-> the getString ( "stu_name"); 
		COUT ID << << "," << endl << name; 
	} 
	// 7. The release of the Statement 
	Delete stmt; 
  	return 0; 
}

　　2. Perform PrepareStatement
