How to write sql query in yii2 - php

I have a raw sql query which i run using yii2 Yii::$app->db->createCommand() but then i wonder i how i can use yii's method of writing queries to actualize the same thing.
$m = "SELECT p.basic_plan_amt AS basic,p.premium_plan_amt AS premium,p.daju_plan_amt AS daju,c.name
AS country FROM price p LEFT JOIN country c ON p.country_id = c.id WHERE p.country_id = " .$country_id;
though the above query works well and provide expected result, but then how can i write the same query using the below format
$model = \backend\models\Price::find()->select([p.basic_plan_amt AS basic,p.premium_plan_amt AS
premium,p.daju_plan_amt AS daju,c.name
AS country])->where(['country_id' => $country_id])->all();

Below are the examples of query in yii hope it will help you More reference
Relation Model
$model = User::find()
->with('comments')
->all();
foreach ($model as $user) {
// get data from relation model
$comments = $user->comments;
......
foreach($comments as $comment){
........
}
}
joinWith()
Sample 1:
$model = User::find()
->joinWith('comments')
->all();
Sample 2:
$model = User::find()
->joinWith('comments')
->orderBy('tbl_comments_id.id, tbl_user.id')
->all();
innerJoinWith()
$model = User::find()
->innerJoinWith('comments', false)
->all();
// equivalent to the above
$model = User::find()
->joinWith('comments', false, 'INNER JOIN')
->all();
Join()
JOIN_TYPE = INNER JOIN, LEFT OUTER JOIN, RIGHT OUTER JOIN, FULL OUTER JOIN etc
Syntax
$query = new Query;
$query ->select(['SELECT COLUMNS'])
->from('TABLE_NAME_1')
->join( 'JOIN_TYPE',
'TABLE_NAME_2',
'TABLE_NAME_2.COLUMN =TABLE_NAME_1.COLUMN'
);
$command = $query->createCommand();
$data = $command->queryAll();
Sample 1:
$query = new Query;
$query ->select([
'tbl_user.username AS name',
'tbl_category.categoryname as Category',
'tbl_document.documentname']
)
->from('tbl_user')
->join('LEFT OUTER JOIN', 'tbl_category',
'tbl_category.createdby =tbl_user.userid')
->join('LEFT OUTER JOIN', 'tbl_document',
'tbl_category.cid =tbl_document.did')
->LIMIT(5) ;
$command = $query->createCommand();
$data = $command->queryAll();
Output Query
SELECT `tbl_user`.`username` AS `name`, `tbl_category`.`categoryname` AS `Category`
FROM `tbl_user`
LEFT OUTER JOIN `tbl_category` ON tbl_category.createdby =tbl_user.userid
LEFT OUTER JOIN `tbl_document` ON tbl_category.cid =tbl_document.did
LIMIT 5
leftJoin()
Sample 1:
$query = new Query;
$query ->select(['tbl_user.username AS name', 'tbl_category.type as Category'])
->from('tbl_user')
->leftJoin('tbl_category', 'tbl_category.createdby = tbl_user.userid')
->limit(2);
$command = $query->createCommand();
$data = $command->queryAll();
Output Query
SELECT `tbl_user`.`username` AS `name`, `tbl_category`.`type` AS `Category`
FROM `tbl_user`
LEFT JOIN `tbl_category` ON tbl_category.createdby = tbl_user.useridd
LIMIT 2

use createcommand() method:
use yii\db\Query();
$connection = \Yii::$app->db;
$query = new Query;
$insql = $connection->createCommand("SELECT* FROM inventory );
$result=$insql->queryAll();
the above method list all data from the inventory table.

Subquery With Yii Active Record

Is it possible to write sub queries with Yii active record?
I need to add a subquery in the FROM clause. Below is the SQL with the subquery but I want to specifically write it using Active Record.
In SQL, Policy has a many to many relationship with policy_vehicles.
SQL Query:
select * from (SELECT Name , GROUP_CONCAT(PV.VehicleId SEPARATOR ',') as VehicleIds
FROM `policies` `t`
LEFT JOIN policy_vehicles PV USING(PolicyId)
WHERE (Type IN ('C', 'E')) AND (Status='Active')
GROUP BY t.PolicyId
) k where VehicleIds like '%1%' AND VehicleIds like '%2%'
This is how I want to use it in the Controller class:
$model = Policy::model();
$model->Status = array('Active');
$model->VehicleIds = array(1,2);
$model->Type = array('C', 'E');
$datas = $model->search()->getData();
print_r($datas);
Search function in the model:
public function search() {
$joins = array();
$criteria = new CDbCriteria;
$criteria->compare('Type', $this->Type);
$criteria->compare('Status', $this->Status);
array_push($joins, 'LEFT JOIN policy_vehicles PV USING(PolicyId)');
$criteria->join = implode(' ', $joins);
return new CActiveDataProvider($this, array(
'criteria' => $criteria,
));
}

Zend Framework 2: how to get columns from joined tables?

I am using Zend Framework 2.4 with TableGateway and need to execute the following query:
SELECT products.title, student.firstname, orders.order_id,
orders.profile_id, orders.status
FROM student
INNER JOIN
(products
INNER JOIN orders ON products.product_id = orders.product_id)
ON student.student_id = orders.student_id
WHERE (((orders.profile_id)='.$id.'));
Here is what I am using:
$select = $this->tableGateway->getSql()->select();
$select->columns(array('*'))
->join('products', 'products.product_id = orders.product_id', array('title'))
->join('student', 'student.student_id = orders.student_id', array('first_name'))
->where(array('orders.profile_id' => $id));
$items = $this->tableGateway->selectWith($select);
return $items;
The problem is that $items does not contain the columns title or first_name. It only contains the columns from the orders table.
What do I need to do to get $items to contain the columns from the joined tables?
try to use an associative array
$select = $this->tableGateway->getSql()->select();
$select->columns(array('*'))
->join('products', 'products.product_id = orders.product_id', array('title' => 'product_title'))
->join('student', 'student.student_id = orders.student_id', array('first_name' => 'student_first_name'))
->where(array('orders.profile_id' => $id));
$items = $this->tableGateway->selectWith($select);
return $items;

Using ResultSetMapping in Doctrine

I have a query like this:
$query = "select run_record_detail.id from
(select max(id) as run_record_id from run_record where delete_flag=0 group by test_run_id) rr
inner join
run_record_detail
on rr.run_record_id = rr.run_record_id
where delete_flag=0 and test_case_id IN (:ids)";
$rsm = new \Doctrine\ORM\Query\ResultSetMapping();
$rsm->addEntityResult('\Test\Entity\RunRecordDetail', 'run_record_detail');
$rsm->addFieldResult('run_record_detail', 'id', 'id');
$query = $this->getEntityManager()->createNativeQuery($query, $rsm);
$query->setParameter('ids', $testCaseIdArray);
$result = $query->getResult();
I am trying to use ResultsetMapping to bind run_record_detail to RunRecordDetail object. I want RunRecordDetail object in the output. But I am getting only its id(as I have selected ). Please help me getting this object.
I am following Doctrine doc http://doctrine-orm.readthedocs.org/en/latest/reference/dql-doctrine-query-language.html

Symfony createNativeQuery, add count()

I have a query in a repository like :
$rsm = new ResultSetMapping;
$rsm->addEntityResult('\My\ProjectBundle\Entity\News', 't');
$rsm->addFieldResult('t', 'id', 'id');
$rsm->addMetaResult('t', 'account_id', 'account_id');
$qb = $this->_em->createNativeQuery(
'SELECT t.*
FROM news as t
LEFT JOIN
LEFT JOIN
WHERE
CONDITIONS CONDITIONS
',
$rsm
);
return $qb->getResult();
I simplified the above query which is used to retrieve the news that meet specific conditions.
I need to add a count() function to this query.
I have an other ManyToOne entity-relationship between Comment and News.
How to modify the query to get the comments number a given news has ?
I'm trying to add a left join to comment and add Count() in the select but I always get errors. How could I resolve this problem ?
Raw SQL with Doctrine is easier like this :
$em = $this->getDoctrine()->getManager()->getConnection();
$query = "
SELECT t.*
FROM news as t
LEFT JOIN
LEFT JOIN
WHERE
CONDITIONS CONDITIONS
";
$stmt = $em->prepare($query);
$stmt->execute();
$result = $stmt->fetchAll();

SQL to function in Codeigniter returns row

I'm trying to get an entire row values from a new SQL query so.
How can I make a function
Select * from table1 t1,table2 t2,table3 t3 where t1.t1_id=t2.t1_id and t3.id=t2.t3_id
to something like this :
In model page
public function getID_researcher($lastname){
$query = $this->db->get_where('researcher', array('lastname' => $lastname));
return $query->row_array();
}
I need to return one row result base on the lastname which is from table1
To clarify here, 'researcher' is the table where it gets data but what I want is the new SQL for me to get the data.
I tried this one but still error.
public function getID_researcher($lastname){
$sql = = $this->db->query('Select * from table1 t1,table2 t2,table3 t3 where t1.t1_id=t2.t1_id and t3.id=t2.t3_id');
$query = $this->db->get_where($sql, array('lastname' => $lastname));
return $query->row_array();
}
to use this query
Select * from table1 t1,table2 t2,table3 t3 where t1.t1_id=t2.t1_id and t3.id=t2.t3_id
you can try to use active record db 'join' like this:
$this->db->from('table1 t1');
$this->db->join('table2 t2', 't1.t1_id = t2.t1_id', 'left');
$this->db->join('table3 t3', 't3.id = t2.t3_id', 'left');
$this->db->where('lastname', $lastname);
$query = $this->db->get();
$c = 0;
foreach($query->result() as $q){
$result[$c]['name'] = $q->lastname;
// put move variable here
$c++;
}
return $result;
hope this help
