数据库行DeleteAll,其中1个字段等于某个东西而其他字段不等于某个东西

Question

我正在努力做到这一点,我想基本上做一个数据库deleteAll,其中一个字段等于某个东西,另一个字段必须不等于某个东西..它用于删除重复的行,所以我想删除除一行之外的所有行...我在下面尝试的方式不起作用,我将不胜感激任何建议:

 $conditions = array (
  "Prox.proxy" => $currentproxytocheck,
  "AND" => array (
   "NOT" => array (
    "Prox.proxyid" => $currentproxyid
   )
  )
 );

$this->Prox->deleteAll(array( 'conditions' => $conditions)); 

编辑:

我的$ conditions数组的打印输出是:

Array
(
    [Prox.proxy] => 62.58.179.2:80
    [AND] => Array
        (
            [NOT] => Array
                (
                    [Prox.proxyid] => 36829
                )

        )

)

来自CAkephp的错误:

Notice (8): Array to string conversion [CORE/cake/libs/model/datasources/dbo_source.php, line 2193]
Warning (512): SQL Error: 1054: Unknown column 'conditions' in 'where clause' [CORE/cake/libs/model/datasources/dbo_source.php, line 673]   

Answer 1

该语法deleteAll是不同find

deleteAll(mixed $conditions, $cascade = true, $callbacks = false)

使用

$this->Prox->deleteAll($conditions); 

你的数组可以像这样构建:

$conditions = array (
    "Prox.proxy" => $currentproxytocheck,
    "Prox.proxyid <>" => $currentproxyid
);

这是一回事,但更具可读性.
