Zend DB - Count(*) 不工作

Question

我的 sql 语句不适用于 Zend，它抱怨 Count(*) 字段...我做错了什么？

// get open/closed
$stmt = $db->query('SELECT status, count(*) as total FROM reported_issues WHERE date_reported >= '.$today.' AND status IN (0,1) GROUP BY status');
while ($row = $stmt->fetch())
{
    switch ($row['status'])
    {
        case 0:
            $totalIssuesToday = $row['total'];
            break;

        case 1:
            $totalIssuesClosedToday = $row['total'];
            break;
    }
}

和错误...

Answer 1

除了其他人注意到的关于 $today 中的值之外，您确实应该在查询中使用绑定参数

<?php

$stmt = $db->query(
    "SELECT status, count(*) as total
       FROM reported_issues
      WHERE date_reported >= ?
        AND status IN (0,1)
      GROUP BY status"
    ,array( $today )
);

Answer 2

投诉实际上是关于 WHERE - 看起来您的 $today 变量不包含您认为应该包含的内容。 具体来说，因为它说：

'SQLSTATE[42S22]: Column not found: 1054 Unknown column 'Y' in 'where clause''

看来您的变量包含不应该存在的 Y 。 count 似乎与该问题无关。

Answer 3

我猜你的 $today 变量已损坏。 将第一行（用于测试）

从

$stmt = $db->query('SELECT status, count(*) as total FROM reported_issues WHERE date_reported >= '.$today.' AND status IN (0,1) GROUP BY status');

更改为：

$sql='SELECT status, count(*) as total FROM reported_issues WHERE date_reported >= '.$today.' AND status IN (0,1) GROUP BY status';
try{
   $stmt = $db->query($sql);
} catch (Exception $e) {
   echo $sql."\n";
   throw $e;
}

然后您可以看到它尝试执行的原始 SQL。
