Yii2 结合多个计数和分组查询

Question

我有一个项目，他们有 3 个状态。现在我需要统计每天每种状态的数量和总数量。

我可以单独列出它们。但是不知道怎么组合。

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();

现在有了这个，我可以在 4 table 秒内将它们单独列出。我想像这样将它们组合成一个 table 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

请帮我解决这个问题。

谢谢。

Answer 1

试试这个：

$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();

我的解决方案是：

$images = ProductImages::find()
                ->where(['pi.product_id'=>$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();
