将+1添加到字段(点击计数器)

Question

如何在c_request字段中添加+1.每次我做插入我想在当前数字上添加1(例如点击计数器)

mysql_query("INSERT INTO ed_names (com_id, c_date, c_time, c_type, c_request, c_by)
        VALUES ($id, CURRENT_DATE, CURRENT_TIME, '.($type == 'normal' ? 1 : 2).',0,$user)");     

$rid = mysql_insert_id();

Answer 1

mysql_query("UPDATE ed_names SET c_request = c_request+1 WHERE id = 'x'");
