我在 Yii 中使用多个嵌套搜索条件来选择一个名为库的模型。条件如下：

    $criteria = new CDbCriteria();
    $criteria->select = 't.id, t.barcode_1_id, t.barcode_2_id, t.library_type_id, t.qc_pass'; 
    $criteria->order = 'patient.id DESC, t.id DESC'; 
    $criteria->together = true;
    $with=array(
            'isolates'=>array(
              'select'=>false,
            ),
            'samples'=>array(
              'select'=>'samples.id, samples.sample_preservation_id, samples.tumor',
            ),
            'patient'=>array(
              'select'=>'patient.id',
            ),
            'flowcells'=>array(
                'select'=>'flowcells.id,flowcells.serial_id',
            ),
            'libraryType'=>array(
                'select'=>'libraryType.id,libraryType.short_name',
            ),
            'samplePreservation'=>array(
              'select'=>'samplePreservation.name',
            ),
            'program'=>array(
                'select'=>false,
                'condition'=>'program.name NOT LIKE "%Lab%"',
            ),
            'runs'=>array(
              'select'=>'runs.id',
            )
          );

    // by run ID
    if (is_array($runs) && (! empty($runs))) {
        $runCriteria = new CDbCriteria();
        $runCriteria->addInCondition("runs.id", $runs, 'OR');
        $criteria->mergeWith($runCriteria, $operator='OR');
        $something=true;
    }

    // libraries without patients
    if ( ($patients=='Unassigned') || (is_array($patients) && in_array('Unassigned',$patients)) ) {
        $unassCriteria = new CDbCriteria();
        $unassCriteria->addCondition('patient.id IS NULL');
        $criteria->mergeWith($unassCriteria, $operator='OR');
        $something=true;
    }

    if ( ($patients=='QC Pass') || (is_array($patients) && in_array('QC Pass',$patients)) ) {
        $qcCriteria = new CDbCriteria();
        $qcCriteria->addCondition('t.qc_pass = 1',$operator='AND');
        $qcCriteria->addCondition('t.created BETWEEN CURDATE() - INTERVAL 30 DAY AND SYSDATE()','AND');
        $criteria->mergeWith($qcCriteria, $operator='OR');
        $something=true;
    }

    if ( ($patients=='Ready for Flowcell') || (is_array($patients) && in_array('Ready for Flowcell',$patients)) ) {
        $readyCriteria = new CDbCriteria();
        $readyCriteria->addCondition('flowcells.id IS NULL',$operator='AND');
        $readyCriteria->addCondition('runs.current_pipeline_node_id = 7',$operator='AND');
        $criteria->mergeWith($readyCriteria, $operator='OR');
        $something=true;
    }

    if (is_array($patients) && (! empty($patients))) {
        $ptArr= array_diff($patients, array('QC Pass','Unassigned','Ready for Flowcell'));
        $ptCriteria = new CDbCriteria();
        $ptCriteria->addInCondition("patient.id", $ptArr,$operator='OR');
        if ($ptArr) $criteria->mergeWith($ptCriteria, $operator='OR');
        $something=true;
    }



    if ($something) $librariesModel=Libraries::model()->with($with)->findAll($criteria);

然后我将这些结果格式化为一个视图。

问题是 Yii 忽略了我的 $operator='OR' 并且总是使用 AND 而不是 OR。这是它生成的 WHERE 子句：

（SELECT 和 JOIN 看起来不错）

...

WHERE 
(
    (

        ( (patient.id IS NULL) AND ( (t.qc_pass = 1) AND (t.created BETWEEN CURDATE() - INTERVAL 30 DAY AND SYSDATE()) ) ) 

        AND ( (flowcells.id IS NULL) AND (runs.current_pipeline_node_id = 7) )

    ) 

    AND (patient.id IN (:ycp0, :ycp1))

) 

AND (program.name NOT LIKE "%Lab%") 



ORDER BY patient.id DESC, t.id DESC, inventory_id ASC

知道为什么 Yii 不让我使用“OR”合并这些标准吗？我的目标是有几个括号表达式，其中包含 AND，但不是排他的。mergeWith 方法应该使用 OR 而不是 AND 将这些条件添加到 WHERE 子句中。

谢谢！

发现了问题。我正在查看更新版本的 CDbCriteria 的文档。它应该是 true 或 false 值：

public function mergeWith($criteria,$useAnd=true)
{
    $and=$useAnd ? 'AND' : 'OR';
    .....

必须按如下方式使用：

$criteria->mergeWith($unassCriteria, false);

代替

$criteria->mergeWith($unassCriteria, 'OR');

因为“或”是真的！
