Linux下通过C++语言代码来操作MySQL数据库

hellowillness 2008-12-28

代码:

#include <cstdlib>
#include <string>
#include "/usr/local/include/mysql/mysql.h"   //安装的mysql的头文件所在的位置
using namespace std;
string host="数据库地址";
string user="用户名";
string pwd="密码";
string dbname="数据库";
string sql="查询语句";
unsigned int port=3309;#端口号
int status;
int main(){
MYSQL *mysql;
mysql=mysql_init(0);
MYSQL_RES *result;
MYSQL_ROW row;
if(mysql_real_connect(mysql,host.c_str(),user.c_str(),pwd.c_str(),dbname.c_str(),port,NULL,CLIENT_FOUND_ROWS)==NULL){
cout << "connect failure!" << endl;
return EXIT_FAILURE;
}else{
cout << "connect success!" << endl;
}
mysql_set_character_set(mysql,"gbk");
status=mysql_query(mysql,sql.c_str());
if(status !=0 ){
cout << "query failure!" << endl;
}
cout << "the status is :" << status << endl;
result=mysql_store_result(mysql);
while(row=mysql_fetch_row(result)){
cout << row[1] <<"|"<< row[2] << endl;
}
mysql_free_result(result);
mysql_close(mysql);
}

编译:

g++ -o test test.cpp -lmysqlclient -I/usr/local/include/mysql/ -L/usr/local/lib/mysql

后面的那些用来指定mysql安装的时候包含路径和库文件路径,具体与你机器上的mysql安装的路径有关。
