SQLSTATE [HY093]：找不到我失踪的东西，我需要一组新的眼睛

Question

不知道我在这里错过了什么，但我不断收到错误。

SQLSTATE [HY093]：无效的参数号：参数没有被定义

$sth = $dbh->prepare("INSERT INTO time (student_id, super_id, d1-date, d2-date, d3-date, d4-date, d5-date, d1-hours, d2-hours, d3-hours, d4-hours, d5-hours) VALUES(:value-1,:value-2,:value-3,:value-4,:value-5,:value-6,:value-7,:value-8,:value-9,:value-10,:value-11,:value-12)"); 
    $pass = array 
    (
     ':value-1'=>$user_id, 
     ':value-2'=>$super_id, 
     ':value-3'=>$data_array[0][0], 
     ':value-4'=>$data_array[0][1], 
     ':value-5'=>$data_array[0][2], 
     ':value-6'=>$data_array[0][3], 
     ':value-7'=>$data_array[0][4], 
     ':value-8'=>$data_array[1][0], 
     ':value-9'=>$data_array[1][1], 
     ':value-10'=>$data_array[1][2], 
     ':value-11'=>$data_array[1][3], 
     ':value-12'=>$data_array[1][4] 
    ); 
    $sth->execute($pass); 

Answer 1

使用_（下划线）。

$sth = $dbh->prepare("INSERT INTO `time` (`student_id`, `super_id`, `d1-date`, `d2-date`, 
     `d3-date`, `d4-date`, `d5-date`, `d1-hours`, `d2-hours`, `d3-hours`, `d4-hours`, 
     `d5-hours`) 
     VALUES(:value_1,:value_2,:value_3,:value_4,:value_5,:value_6,:value_7, 
     :value_8,:value_9,:value_10,:value_11,:value_12)"); 

Answer 2

不能使用破折号作为参数名称的一部分（我认为这是根据this post保持与Oracle兼容）。

也许是这样的：不是连字符

$sth = $dbh->prepare("INSERT INTO time (student_id, super_id, d1-date, d2-date, d3-date, d4-date, d5-date, d1-hours, d2-hours, d3-hours, d4-hours, d5-hours) VALUES (:value1,:value2,:value3,:value4,:value5,:value6,:value7,:value8,:value9,:value10,:value11,:value12)"); 
    $pass = array 
    (
     ':value1'=>$user_id, 
     ':value2'=>$super_id, 
     ':value3'=>$data_array[0][0], 
     ':value4'=>$data_array[0][1], 
     ':value5'=>$data_array[0][2], 
     ':value6'=>$data_array[0][3], 
     ':value7'=>$data_array[0][4], 
     ':value8'=>$data_array[1][0], 
     ':value9'=>$data_array[1][1], 
     ':value10'=>$data_array[1][2], 
     ':value11'=>$data_array[1][3], 
     ':value12'=>$data_array[1][4] 
    ); 
    $sth->execute($pass);
