PHP Mysqli如何选择最近24小时的数据

Question

我想在我已尝试使用此查询的最近24小时内添加数据，但未显示任何内容：

$result = $db->query("
    SELECT reclamations.* , customers.*
    FROM reclamations
    LEFT JOIN customers ON reclamations.id_customer = customers.id
    ORDER BY reclamations.code
    WHERE reclamation_date = DATE_SUB( NOW() - INTERVAL 24 HOUR"));

Answer 1

您目前有一个PHP 和 MySQL语法错误，因为右括号在右双引号的错误一侧。

如果列大于或等于现在减去1天，以下情况如何：

$result = $db->query("
    SELECT reclamations.* , customers.*
    FROM reclamations
    LEFT JOIN customers 
        ON reclamations.id_customer = customers.id
    ORDER BY reclamations.code
    WHERE reclamation_date >= NOW() - INTERVAL 1 DAY;
");

Answer 2

尝试这个：

$result = $db->query("
    SELECT reclamations.* , customers.*
    FROM reclamations
    LEFT JOIN customers ON reclamations.id_customer = customers.id
    ORDER BY reclamations.code
    WHERE reclamation_date BETWEEN DATE_SUB(NOW(), INTERVAL 24 HOUR) and NOW()";
