Question

我正在尝试在 PHP PDO 中运行 SQL 查询：

$stmt = $pdo_conn->prepare("SELECT * from integra_status where type <> :type1 and category1 = :category and (status = :status1 or status = :status2) 
    UNION 
    SELECT * from integra_status WHERE type = :type2 and maintenance_fromdate <= :maintenance_fromdate AND maintenance_todate >= :maintenance_todate and category = :category2 order by sequence ASC ");
    $stmt->execute(array(':type1' => 'Maintenance', ':category1' => $result["sequence"], ':status1' => 'Open', ':status2' => 'Resolved', 
    ':type2' => 'Maintenance', ':maintenance_fromdate' => 'DATE_ADD(NOW(), INTERVAL 7 DAY)', ':maintenance_todate' => 'DATE_SUB(NOW(), INTERVAL 2 DAY)', ':category2' => $result["sequence"] ));

但是我得到了这个输出：

致命错误：未捕获异常'PDOException'，消息'SQLSTATE [HY093]：参数号无效：参数未定义'/home/integra/public_html/service_status/index.php:48堆栈跟踪：＃ 0 /home/integra/public_html/service_status/index.php(48）：PDOStatement-＆gt; execute（Array）＃1 /home/integra/public_html/index.php(124）：include（'/ home / integra / p ......'）第48行/home/integra/public_html/service_status/index.php中的＃2 {main}

Answer 1

你正在传递：

':category1' => $result["sequence"]

在您的执行语句中

，而您的查询显示为：

where type <> :type1 and category1 = :category and

另请注意，您将无法使用

':maintenance_fromdate' => 'DATE_ADD(NOW(), INTERVAL 7 DAY)'

如你所愿。直接在查询中使用该功能：

maintenance_fromdate <= DATE_ADD(NOW(), INTERVAL 7 DAY)

PDO Sql联合查询显示错误
