MFC连接Mysql数据库执行查询和插入
配置环境:
include:mysql.h文件
lib:libmysql.lib文件
dll:;libmysql.dll文件
连接代码:
MYSQL m_sqlCon;
MYSQL_RES *m_res;
MYSQL_ROW row;
//初始化数据库
mysql_init(&m_sqlCon);
// 设置连接数据库字符串
CString conn_ip,conn_port,conn_dbname,conn_user,conn_password;
if(!mysql_real_connect(&m_sqlCon,conn_ip,conn_user,conn_password,conn_dbname,int_port,NULL,0))
{
AfxMessageBox(_T("访问数据库失败!"));
return;
}
mysql_query(&m_sqlCon,"SET NAMES 'GB2312'");//解决从数据库中读取数据后汉字乱码显示的问题
//定义sql语句
const char *sql = "select * from table";
//执行查询
m_res = mysql_store_result(&m_sqlCon);
//如果为空则返回
if(NULL == m_res)
{ return; }
//重复读取行,把数据放入列表中,直到row为NULL
while (row = mysql_fetch_row(m_res))
{
for (int rols = 0; rols < 2; rols++)
{
CString myreaddata(row[rols]);
list.AddString(myreaddata);
}
}
//执行插入
const char *sql = "insert into tb_rdchange(way_id,sp_way_id) values(4,4)";
if(mysql_real_query(&m_sqlCon, sql,(unsigned long)strlen(sql)))
{
return;
}
