Question

我有一个项目，他们有3个状态。现在，我需要计算每天每种状态的数量和总数。

我可以单独列出它们。但是不知道如何将它们结合起来。

这是我的代码：

    $passed_counts = (new \yii\db\Query())
    ->select(['date', 'week', 'count(sku) as sku'])
    ->from('qa3d')
    ->where(['status' => 'Passed'])
    ->groupBy('date')->all();

    $failed_counts = (new \yii\db\Query())
    ->select(['date', 'week', 'count(sku) as sku'])
    ->from('qa3d')
    ->where(['status' => 'Failed'])
    ->groupBy('date')->all();

    $onhold_counts = (new \yii\db\Query())
    ->select(['date', 'week', 'count(sku) as sku'])
    ->from('qa3d')
    ->where(['status' => 'On Hold'])
    ->groupBy('date')->all();

    $total_counts = (new \yii\db\Query())
    ->select(['date', 'week', 'count(sku) as sku'])
    ->from('qa3d')
    ->groupBy('date')->all();

现在，我可以在4个表中分别列出它们。我想像这样将它们组合在一张桌子上，但不知道如何。

date Passed Failed On Hold Total

2019-01-16 1 4 2 7

2019-01-17 1 0 2 3

请帮助我。

谢谢。

Answer 1

尝试一下：

$data = (new \yii\db\Query())
->select([
    'date', 
    'SUM( IF(status = "Passed", 1, 0) ) AS passed', 
    'SUM( IF(status = "Failed", 1, 0) ) AS failed', 
    'SUM( IF(status = "On Hold", 1, 0) ) AS onhold', 
    'COUNT(*) AS total'
])
->from('qa3d')
->groupBy('date')
->all();

我的解决方法是：

$images = ProductImages::find()
                ->where(['pi.product_id'=>$id])
                ->select([
                    'pi.*',   
                    'f.count as firstCount',
                    's.count as secondCount',
                ])
                ->from([
                    'pi' => ProductImages::tableName(),
                ])

                ->leftJoin(['f'=>First::find()
                    ->select('object_id, COUNT(*) as count')
                    ->where(['type'=>120])
                    ->groupBy(['object_id'])
                ], 'f.object_id = pi.id')

                ->leftJoin(['s'=>Second::find()
                    ->select('image_id, COUNT(*) as count')
                    ->where([
                        'type'=>101,
                        'is_personal'=>false,
                    ])
                    ->groupBy(['image_id'])
                ], 's.image_id = pi.id')

                ->asArray()
                ->all();

Yii2结合多个计数和按查询分组
