Question

我正在开发一个Android设备连接到WAMP服务器的系统。我正在尝试返回一些行，具体取决于用户在Android应用中选择的日期。我必须说日期的默认值是0000-00-00，但这些值可以更新为实际日期。问题是，如果我在设备中选择返回日期为0000-00-00的行，则此方法有效。但是，如果我选择返回某些实际日期（例如2013-08-08）的行，则不起作用（0行受影响）。我认为这是一个格式问题，但日志显示它应该是什么。

我不知道一切都很清楚。

我会复制下面的代码，以防您提供帮助。

PHP（日期称为'fecha'）

<?php


// array for JSON response
$response = array();


// include db connect class
require_once __DIR__ . '/db_connect.php';

$db = new DB_CONNECT(); 
$fecha = $_GET['fecha'];
$result = mysql_query("SELECT *FROM resultados2 WHERE fecha = $fecha") or die(mysql_error());


if (mysql_num_rows($result) > 0) {

    $response["resultado"] = array();

    while ($row = mysql_fetch_array($result)) {
        // temp user array
        $resultado = array();
        $resultado["id"] = $row["id"];
        $resultado["nombre"] = $row["nombre"];
        $resultado["tablet"] = $row["tablet"];
        $resultado["fecha"] = $row["fecha"];






        array_push($response["resultado"], $resultado);
    }
    $response["success"] = 1;
    $response["message"] = "Returned";



    echo json_encode($response);
} else {

    $response["success"] = 0;
    $response["message"] = "Error";

    echo json_encode($response);

}
?>

Answer 1

使用WHERE fecha = '$fecha'（请注意'）。

现在，Mysql会将$fecha的值“识别”为“值”，而不是“列名。

Android，MySQL，JSON：MySQL脚本只返回值row date是0000-00-00
