仿照php的mysqli扩展自己使用MySQL的C Interface实现了一个简单的mysql操作类

#include "MySQLi.h" MySQLi::MySQLi(std::string hostname, std::string username, std::string password, std::string dbname, unsigned int port=3306) { this->m_hostname = hostname; this->m_username = username; this->m_password = password; this->m_dbname = dbname ; this->m_port = port ; //this->m_unix_socket = unix_socket; //this->m_client_flag = client_flag; this->mysql_conn = mysql_init(NULL); mysql_real_connect( this->mysql_conn, (this->m_hostname).c_str(), (this->m_username).c_str(), (this->m_password).c_str(), (this->m_dbname).c_str(), this->m_port, (this->m_unix_socket).c_str(), this->m_client_flag ); } MySQLi::~MySQLi() { if (this->mysql_conn) mysql_close(this->mysql_conn); } void MySQLi::close() { mysql_close(this->mysql_conn); } int MySQLi::select_db(std::string dbname) { this->m_dbname = dbname; return mysql_select_db(this->mysql_conn, (this->m_dbname).c_str()); } MySQLi_Result* MySQLi::query(std::string query) { mysql_query(this->mysql_conn, query.c_str()); return new MySQLi_Result(mysql_use_result(this->mysql_conn)); }
