PDO插入无法正常工作

Question

我不知道我做错了什么.它不起作用.

我这么久都很震惊.我无法理解.

$sql="INSERT INTO hr_daily_claim(date,
                                 site,
                                 from,
                                 to,
                                 rental,
                                 vehicle,
                                 claim_id,
                                 parking,
                                 beverages,
                                 others) 

                          VALUES(:date,
                                 :site,
                                 :from,
                                 :to,
                                 :rental,
                                 :vehicle,
                                 :claim_id,
                                 :parking,
                                 :beverages,
                                 :others)";
$stmt = $db->prepare($sql);
$stmt->execute(array(
                     ':date'     => $date, 
                     ':site'     => $site, 
                     ':from'     => $from, 
                     ':to'       => $to,
                     ':rental'   => $rental,
                     ':vehicle'  => $vehicle,
                     ':claim_id' => $cliamId,
                     ':parking'  => $parking,
                     ':beverages'=> $beverages,
                     ':others'   => $others    ));

请有人帮助我.它没有给我任何错误.但受影响的行= 0; 根本不插入.

下面是表格结构

 `id` int(11) NOT NULL AUTO_INCREMENT,
  `claim_id` varchar(45) DEFAULT NULL,
  `date` varchar(10) DEFAULT NULL,
  `site` varchar(45) DEFAULT NULL,
  `from` varchar(45) DEFAULT NULL,
  `to` varchar(45) DEFAULT NULL,
  `rental` int(11) DEFAULT NULL,
  `vehicle` int(11) DEFAULT NULL,
  `parking` int(11) DEFAULT NULL,
  `beverages` int(11) DEFAULT NULL,
  `others` int(11) DEFAULT NULL,
  `timestamp` timestamp NULL DEFAULT CURRENT_TIMESTAMP,

from,to是MySQL 中的保留字.你需要用反引号包装它.

$sql="INSERT INTO hr_daily_claim(
                `date`,
                `site`,
                `from`,                //<-------- This
                `to`,                  //<-------- This
                `rental`, 
                `vehicle`,
                `claim_id`,
                `parking`,
                `beverages`,
                `others`
                        ) 

旁注:有可能是在一个错字$cliamId变量':claim_id' => $cliamId,这也许应该理解为':claim_id' => $claimId,,这样做检查,因为这些变量没有在你的问题张贴.

如果一个失败,您的整个查询将失败.需要注意的另一件事是,$claimId并且$claimid不一样.变量区分大小写.
