Changing sql query to yii2 format - php

Question

Am using dataProvider and i would like to convert a query in sql so that it follows the dataProvider way of representing data
This is the raw sql
SELECT
tblpritems.PRlineID
, tblpritems.Tracking_Code
, tblpritems.Description
, tblpritems.Quantity
, tblpritems.Unit_Price
, tblpritems.Extended_price
, tblpritems.PRID
, tblpritems.pr_solicitation_id
, tblpritems.date_item_received
, tblpritems.Quantity_received
, tblpritems.Remarks_on_receipt
, tblpritems.Received_by
FROM
prts.tblpritems
INNER JOIN prts.tblpr
ON (tblpritems.PRID = tblpr.PRID)
INNER JOIN prts.tblprsolicitations
ON (tblprsolicitations.PRID = tblpr.PRID) AND (tblpritems.pr_solicitation_id = tblprsolicitations.pr_solicitation_id)
INNER JOIN prts.tblprsuppliers
ON (tblprsuppliers.pr_solicitation_id = tblprsolicitations.pr_solicitation_id)
INNER JOIN prts.tblpo
ON (tblpo.pr_supplier_id = tblprsuppliers.pr_supplier_id)
where tblpr.PRID=".$val." and tblpo.PO_Status_ID=7 and item_received_status=0
These are the relations i have in the tblpritems
public function getPR()
{
return $this->hasOne(Tblpr::className(), ['PRID' => 'PRID']);
}
/**
* #return \yii\db\ActiveQuery
*/
public function getPrSolicitation()
{
return $this->hasOne(Tblprsolicitations::className(), ['pr_solicitation_id' => 'pr_solicitation_id']);
}
Currently am using
$dataProvider = new SqlDataProvider([
'sql' => $sql,
'pagination' => [
'pageSize' => 10,
],
]);
But the problems is that i cant access $dataProvider->getAttributes() in sql dataProvider
I would like the sql code above to be in this format
$query = Tblprsuppliers::find()
->Joinwith('prSolicitation', 'prSolicitation.pr_solicitation_id = tblprsuppliers.pr_solicitation_id')
->Joinwith('supplier', 'supplier.supplier_id = tblprsuppliers.supplier_id')
->JoinWith('currency', 'currency.CurrencyID = tblprsuppliers.currency_id ');
How can i achieve this
This is the database schema

when you have complex sql related that return instance of model you can use findBySql this way
$sql = 'SELECT
tblpritems.PRlineID
, tblpritems.Tracking_Code
, tblpritems.Description
, tblpritems.Quantity
, tblpritems.Unit_Price
, tblpritems.Extended_price
, tblpritems.PRID
, tblpritems.pr_solicitation_id
, tblpritems.date_item_received
, tblpritems.Quantity_received
, tblpritems.Remarks_on_receipt
, tblpritems.Received_by
FROM
prts.tblpritems
INNER JOIN prts.tblpr
ON (tblpritems.PRID = tblpr.PRID)
INNER JOIN prts.tblprsolicitations
ON (tblprsolicitations.PRID = tblpr.PRID) AND (tblpritems.pr_solicitation_id = tblprsolicitations.pr_solicitation_id)
INNER JOIN prts.tblprsuppliers
ON (tblprsuppliers.pr_solicitation_id = tblprsolicitations.pr_solicitation_id)
INNER JOIN prts.tblpo
ON (tblpo.pr_supplier_id = tblprsuppliers.pr_supplier_id)
where tblpr.PRID=".$val." and tblpo.PO_Status_ID=7 and item_received_status=0';
$model = Pritems::findBySql($sql)->all();
