我有以下需要在yii2中使用的mysql查询 -
select tsell.district,tsell.totalsale as sell,coalesce(tcollection.collection,0) as collection from(SELECT district, coalesce(sell.sale,0) as totalsale FROM `districts` left join (SELECT parties_district, billdate,sum(billamount) as sale FROM `bills` left join parties on bills.bills_partyname = parties.parties_partyname group by parties_district) as sell on sell.parties_district = districts.district) as tsell left join (SELECT parties_district,payment_date,COALESCE(sum(payment_amount),0) as collection FROM `payment` left join parties on payment.payment_partyname = parties.parties_partyname group by parties_district) as tcollection on tsell.district = tcollection.parties_district
我的搜索模型是
<?php
namespace frontend\modules\districtreport\models;
use Yii;
use yii\base\Model;

use yii\db\Command;
$query = \Yii::$app->db;
/**

*/
class PartiesSearch extends Parties
{
public $bills;
public $district;
public $sale;
public $sell;
public $collection;
/**

*/
public function rules()
{
return [
[['party_id'], 'integer'],
[['parties_partyname', 'address', 'parties_district', 'name_manager', 'transport', 'dlno', 'instruction', 'con', 'district','sale','sell','collection'], 'safe'],
];
}
/**

public function scenarios()
{
// bypass scenarios() implementation in the parent class
return Model::scenarios();
}
/**

$query = Parties::findBySql($sql);
// add conditions that should always apply here

$this->load($params);
if (!$this->validate()) {

// $query->where('0=1');
return $dataProvider;
}
// grid filtering conditions
$query->andFilterWhere([

]);
$query->andFilterWhere(['like', 'parties_partyname', $this->parties_partyname])

->andFilterWhere(['like', 'collection', $this->collection])
->andFilterWhere(['like', 'district', $this->district]);
return $dataProvider;
}
}
但问题是我无法对列进行排序或过滤。所以我想使用activerecord来运行查询而不是findbysql。请帮我在activerecord中构建此查询。
我的index.php文件看起来像 -
<?php
use yii\helpers\Html;
use yii\grid\GridView;
//use kartik\widgets\DatePicker;
use kartik\daterange\DateRangePicker;
use kartik\form\ActiveForm;
use dosamigos\datepicker\DatePicker;
/* @var $this yii\web\View */
/* @var $searchModel frontend\modules\districtreport\models\PartiesSearch */
/* @var $dataProvider yii\data\ActiveDataProvider */
$this->title = 'Parties';
$this->params['breadcrumbs'][] = $this->title;
?>
<div class="parties-index">
<h1><?= Html::encode($this->title) ?></h1>
<?php // echo $this->render('_search', ['model' => $searchModel]); ?>
<!-- <p>
<?= Html::a('Create Parties', ['create'], ['class' => 'btn btn-success']) ?>
</p> -->
<!-- <div class="custom-filter">
Date range:
<input name="start" />
<input name="end" />
</div> -->
<?= GridView::widget([
'dataProvider' => $dataProvider,
'filterModel' => $searchModel,
'columns' => [
['class' => 'yii\grid\SerialColumn'],
'district',
'sell',
'collection',
//['class' => 'yii\grid\ActionColumn'],
],
]); ?>
</div>
这是我的PartiesController.php
<?php

}
/**

*/
public function actionIndex()
{
$searchModel = new PartiesSearch();
$dataProvider = $searchModel->search(Yii::$app->request->queryParams);

请注明look
$dataProvider = new SqlDataProvider([
'sql' => 'SELECT Name, Title, COUNT(ArticleTags.ID) AS TagCount ' .
'FROM Authors ' .
'INNER JOIN Articles ON (Authors.ID = Articles.AuthorID) ' .
'INNER JOIN ArticleTags ON (Articles.ID = ArticleTags.ID) ' .
'WHERE Name=:author' .
'GROUP BY ArticleID',
'params' => [':author' => 'Arno Slatius'],
]);

在查询中，您错过了区别名
select
tsell.district as district,
tsell.totalsale as sell,
coalesce(tcollection.collection,0) as collection
from
(SELECT
district,
coalesce(sell.sale,0) as totalsale
FROM `districts`
left join
(SELECT
parties_district,
billdate,
sum(billamount) as sale
FROM `bills`
left join parties on bills.bills_partyname = parties.parties_partyname
group by parties_district) as sell
on sell.parties_district = districts.district) as tsell
left join
(SELECT
parties_district,
payment_date,
COALESCE(sum(payment_amount),0) as collection
FROM `payment`
left join parties on payment.payment_partyname = parties.parties_partyname
group by parties_district) as tcollection
on tsell.district = tcollection.parties_district
对于排序我建议你这个符号
$dataProvider->setSort([
'attributes' => [
'sell' => [
'asc' => ['tsell.sell' => SORT_ASC],
'desc' => ['tsell.sell' => SORT_DESC],
'label' => 'Sell'
],
'collection' => [
'asc' => ['collection' => SORT_ASC],
'desc' => ['collection' => SORT_DESC],
'label' => 'Collection'
]
'district' => [
'asc' => ['tsell.district' => SORT_ASC],
'desc' => ['tsell.district' => SORT_DESC],
'label' => 'District'
]
]
]);
请确保您仅在一个模型类中声明了变量$bills, $district, $sale, $sell, $collection。
如果在几个扩展的searchModel中使用这些变量，则仅在模型中声明
否则只在searhModel中声明..
当模型或modelSearch函数使用时，永远不要在同一个var中声明覆盖其他var和不匹配。
