Question

这是我进行更新查询的方式，该查询正在运行，但没有成功，也没有错误结果。虽然我已经在MySql工作台中使用参数手动测试了查询，但是一切正常。我所缺少的。我也不知道为什么不成功，为什么不抛出任何异常或错误。

function UpdateLeaveDetailRequestStatus(){

    global $connPDO;
    date_default_timezone_set("Asia/Karachi");
    //$connPDO->beginTransaction();
    $currentDate = date('Y-m-d H:i:s');

    $binds = array(
        ":leave_start_date"                     =>   $_POST["leaveStartDate"],
        ":leave_end_date"                       =>   $_POST["leaveEndDate"],
        ":leave_total_days"                     =>   $_POST["leaveTotalDays"],
        ":leave_type"                           =>   $_POST["leaveType"],
        ":leave_in_out_time"                    =>   $_POST["leaveInOutTime"],
        ":leave_duration"                       =>   $_POST["leaveDuration"],
        ":leave_reason"                         =>   $_POST["leaveReason"],
        ":leave_current_status_id"              =>   $_POST["leaveCurrentStatusId"],
        ":leave_current_status_set_by"          =>   $_COOKIE["userID"],
        ":leave_current_status_set_dateTime"    =>   $currentDate,
        ":leave_detail_id"                      =>   $_POST["leaveDetailId"]

    );

    echo $_POST["empId"] ."\n";
    echo $_POST["leaveStartDate"].       "\n";
    echo $_POST["leaveEndDate"].         "\n";
    echo $_POST["leaveTotalDays"].       "\n";
    echo $_POST["leaveType"].            "\n";
    echo $_POST["leaveInOutTime"].       "\n";
    echo $_POST["leaveDuration"].        "\n";
    echo $_POST["leaveReason"].          "\n";
    echo $_POST["leaveCurrentStatusId"]. "\n";
    echo $_COOKIE["userID"].             "\n";
    echo $currentDate.                   "\n";
    echo $_POST["leaveDetailId"].        "\n";

    $sqlProjectQueueUpdate =
        "Update `ttl_employee_switch`.`tbl_emp_leave_details`
          SET
           `leave_start_date`                       = `:leave_start_date`,
           `leave_end_date`                         = `:leave_end_date`,
           `leave_total_days`                       = `:leave_total_days`,
           `leave_type`                             = `:leave_type`,
           `leave_in_out_time`                      = `:leave_in_out_time`,
           `leave_duration`                         = `:leave_duration`,
           `leave_reason`                           = `:leave_reason`,
           `leave_current_status_id`                = `:leave_current_status_id`,
           `leave_current_status_set_by`            = `:leave_current_status_set_by`,
           `leave_current_status_set_dateTime`      = `:leave_current_status_set_dateTime`
           WHERE `leave_detail_id`                 = `:leave_detail_id`";

    echo $sqlProjectQueueUpdate;
    $statement = $connPDO->prepare($sqlProjectQueueUpdate);
    $output = $statement->execute($binds);

    //$output = CustomPDO($connPDO, $sqlProjectQueueUpdate, $binds);
    echo $output;
}

这是调用上述函数的javascript：

if(leaveInOutTime == null || leaveInOutTime == undefined ||leaveInOutTime=="")
    {
        leaveInOutTime = "00:00:00";
    }

    var data = {};
    var actionName= "";

    data =   {
        //"action"                :   actionName,
        "empId"                   :   empID,
        "leaveStartDate"          :   leaveStartDate,
        "leaveEndDate"            :   leaveEndDate,
        "leaveTotalDays"          :   leaveTotalDays,
        "leaveDuration"           :   leaveDuration,
        "leaveType"               :   leaveType,
        "leaveInOutTime"          :   leaveInOutTime,
        "leaveReason"             :   leaveReason
    };

    //alert($("#selectedLeaveFormId").attr("leave-id"));

    if(isInsert ==false){
        data["leaveCurrentStatusId"] = 1;
        data["leaveDetailId"] = $("#selectedLeaveFormId").attr("leave-id");
        data["action"] = "UpdateLeaveDetailRequestStatus";
    }
    else
    {
        data["action"] = "GenerateLeaveDetailRequest";
    }



    console.log(data);



    console.log(empID);
    console.log(leaveStartDate);
    console.log(leaveEndDate);
    console.log(leaveTotalDays);
    console.log(leaveDuration);
    console.log(leaveType);
    console.log(leaveInOutTime);
    console.log(leaveReason);


    $.ajax({
        url  :  baseURL + "EmpLeave.php",
        type : "POST",
        data : data,
        success : function(data, textStatus, XMLHttpRequest) {
            console.log(data);

            if(data == 1)
            {
                ClearForm();
                if(isInsert){
                console.log("Successful entry" + data);
                }else{
                    alert("Leave Reocrd Updated.")
                }

            }
            else if(data == 2)
            {

                alert("Failed to generate leave request.");

            }
            else
            {
                console.log(data);
                alert("An error occurred, please Contact Administrator. " + data);

            }
        },
        error: function(jqXHR, textStatus, errorThrown) {
            alert("An error occured when adding Project Question. Please Contact Administrator."+ errorThrown);
        }
    });

请摆脱所有这些反引号：

$sqlProjectQueueUpdate =
    "UPDATE ttl_employee_switch.tbl_emp_leave_details
      SET
       leave_start_date                       = :leave_start_date,
       leave_end_date                         = :leave_end_date,
       leave_total_days                       = :leave_total_days,
       leave_type                             = :leave_type,
       leave_in_out_time                      = :leave_in_out_time,
       leave_duration                         = :leave_duration,
       leave_reason                           = :leave_reason,
       leave_current_status_id                = :leave_current_status_id,
       leave_current_status_set_by            = :leave_current_status_set_by,
       leave_current_status_set_dateTime      = :leave_current_status_set_dateTime
       WHERE leave_detail_id                 = :leave_detail_id";

反引号不属于列分配的RHS，它应该只是字符串（或其他类型）文字。无论如何，由于您的列名和表名不是保留的MySQL关键字，因此这里不需要反引号。
