Zend_Db PDO异常出现在mySQL View中?

Zend 1.12.1更新为1.12.3并转为x_debug onOLD_PASSWORD default

我重新运行一个曾经无缝运行的程序,它现在有一个致命的PDOException,详情如下:

错误:

SQLSTATE[42S22]: Column not found: 1054 Unknown column 'place_fcb.userid' in 'group statement'

实际SQl查询:

SELECT `C`.* 
FROM (SELECT `place_fcb`.* FROM `place_fcb`) 
AS `C` 
WHERE (place_type_id != '176') 
GROUP BY place_fcb.userid
HAVING (place_fcb.pda >= '2009-12-21') 
AND (place_fcb.pda <= '2010-01-20')

Zend_Db_table_Abstract:

 public function getPlacefcb($start_date = '', $end_date = '', $r_id = '')
    {
        $sub_sql = $this->select()->from('place_fcb');

        $select = $this->select()
            ->setIntegrityCheck(false)
            ->from(array('C' => new Zend_Db_Expr('('.$sub_sql.')')))
            ->where("place_type_id != '176'")
            ->group('place_fcb.userid');

        if($start_date != '')
            $select->having('`place_fcb`.`pda` >= ?', $start_date);

        if($end_date != '')
            $select->having('`place_fcb`.`pda` <= ?', $end_date);

        if($region_id != '')
            $select->having('`place_fcb`.`r_id` = ?', $r_id);

        return $rowset = $this->fetchAll($select);
    }

place_fcb的MySQL:

place_fcb是一个VIEW而不是一个表。它有以下相关领域

place_id
r_id
place_type_id
pda
userid

我可以通过将SQl语句更改为:

来删除异常并返回相同的结果
    SELECT `C`.* 
    FROM (SELECT `place_fcb`.* FROM `place_fcb`) 
    AS `C` 
    WHERE (place_type_id != '176') 
    GROUP BY userid
    HAVING (pda >= '2009-12-21') 
    AND (pda <= '2010-01-20')

即。删除所有表后缀......

但我如何用Zend修复它?为什么突然出错?

1 个答案:

答案 0 :(得分:1)

为什么您的查询使用子查询:

->from(array('C' => new Zend_Db_Expr('('.$sub_sql.')')))

而不仅仅是:

->from('place_fcb')

对于前者,外部查询中没有place_fcb表;因此,这些合格的引用失败了(而且总是如此,所以在升级之前我无法看到它是如何为你工作的。)

如果您坚持保留子查询,则可以将子查询的别名从'C'重命名为'place_fcb',尽管这可能会导致长期混淆;最好将合格的引用重命名为'place_fcb''C'
