I am trying to get all order ids, i am not sure to use function or execute sql query
which one is fast considering the performance ?
Is their any way get it ?
It's very light query, even if you have tens of thousands of orders.
$orders = Db::getInstance()->executeS('SELECT `id_order` FROM `'._DB_PREFIX_.'orders`');
$ids = array_map(function ($row) {
return $row['id_order'];
}, $orders);
$orders= Order::getOrderIdsByStatus($id_status);
$OrderIds = array_column(Order::getOrdersWithInformations(),'id_order' );

i want to ask about sql in postgresql, i got data from join with 3 table, i got the result but i got multiple data like this image
result
and here my sql code in postgresql
select users.* from users inner join model_has_roles on model_has_roles.model_id = users.id
left join roles on roles.id = model_has_roles.role_id where roles.name not in ('job-seeker') order by users.name asc
how to fix this query where i got the multiple data only 1 data to show.
and i want this sql to implement to laravel query and here my code now
public function getAccountList(){
$req = app(Request::class);
// $getAccount = User::query();
$getAccount = User::join('model_has_roles', function($join) {
$join->on('users.id', '=', 'model_has_roles.model_id');
})->leftJoin('roles', function($join){
$join->on('model_has_roles.role_id', '=', 'roles.id');
});
$getAccount->whereNotIn('roles.name', ['job-seeker']);
if ($q = $req->query('q')) {
$searchTerm = trim(strtolower($q));
$getAccount->whereRaw(
'LOWER(users.name) like (?) or LOWER(users.email) like (?)',
["%{$searchTerm}%", "%{$searchTerm}%"]
);
}
// $getAccount->get()->unique('name');
$getAccount->select(['users.*']);
$paginator = $this->pagination($getAccount);
return $this->paginate($paginator, new UserTransformer);
}
how to fix the query only 1 data to show not the multiple same data. thank you for helping me. God Bless You
use distinct()
$data = DB::table('test')->[your query builder]->distinct()->get();
Laravel Query Builder Docs
Just change a bit to make it related to your query builder
In my back-end I'm using KnexJS with PostgreSQL and I have to build a Knex function using its SQL builder without the raw SQL.
It is the first time for me to use KnexJS and I got few issues.
What I have to build is as shown in the SQL example
UPDATE
feed
SET
status = 'SOME_STATUS'
WHERE
created_at <= 'SOME_TIMESTAMP'
AND conversation_id = 'ID';
This SQL is updating the table feed all columns with status and where two conditions are met.
In Knex what I tried as example code of my idea
answerPendingMessages(feeds) {
return this.tx(tableName).where({
conversationId,
createdAt <= timestamp // This not idea how to do in Knex ???
}).update({
status: 'ANSWERED'
})
}
In this above function my concern is how to actually convert the where part as one of the consitions is createdAt <= 'TIMESTAMP'
I understood that I can use where with an object but cannot understand how to include the <=
Also I should update the updatedAt column with the new timestamp but also that blocked me at the moment.
Te result in the end should that all columns which met the conditions are updated status to some some status and also a new updatedAt timestamp.
I'm not sure if there is a specific way with Knex to do so
This answer is to provide my goal for my previous question.
The script I'm showing is not doing anything and I don't know know to make it to work.
answerPendingMessages(feeds) {
if (isEmpty(feeds)) return Promise.resolve([]);
const { conversationId, createdAt } = feeds;
return this.tx(tableName)
.where(
columns.conversationId === conversationId,
columns.createdAt <= createdAt
)
.update({
[columns.status]: 'ANSWERED',
[columns.updatedAt]: new Date(),
});
}
What should happen here is that to update a table where I have two conditions but one of then is 'smaller than or equals' relation.
As the output of this should be that all rows where the 2 conditions are met are update status column.
Right now the script is not failing either success piratically nothing is happening.
I'm trying to set up a subquery in ZendFramework 2 and I got an issue with the limit function for a Select object. Whatever I do, numeric value is put between quotes and makes my query fails : I should get LIMIT 1 and instead I get LIMIT '1'.
Seems this is not the first time this issue has been encountered, I saw some have asked about this issue before (like 8 months ago) but without getting any proper answer.
I also saw this issue has been marker as resolved in 2012 (https://github.com/zendframework/zf2/pull/2775) so I really don't understand what's happening there.
Here's my code in ZF2 :
$resultSet = $this->tableGateway->select( function (Select $select) use ($params) {
$sub = new Select();
$sub->from(array('temp' => 'scores'))
->columns(array(new \Zend\Db\Sql\Expression("id AS id")))
->where(array('temp.glitch' => array('None', 'Glitch')))
->where('temp.zone=scores.zone')
->order('temp.multi DESC, temp.score DESC')
->limit(1);
$select->join('players', 'player=players.id', array('player_name' => 'name', 'player_url' => 'name_url'))
->join('countries', 'players.country=countries.id', array('country_name' => 'name', 'country_iso' => 'iso'))
->join('cars', 'car=cars.id', array('car_name' => 'name'), 'left')
->join('zones', 'zone=zones.id', array('zone_name' => 'name'));
$select->where(array('scores.id' => $sub));
$select->order('scores.zone ASC');
print_r($select->getSqlString());
});
This should render the following query (which I get right except LIMIT '1' instead of LIMIT 1) :
SELECT "scores".*, "players"."name" AS "player_name", "players"."name_url" AS "player_url", "countries"."name" AS "country_name", "countries"."iso" AS "country_iso", "cars"."name" AS "car_name", "zones"."name" AS "zone_name"
FROM "scores" INNER JOIN "players" ON "player"="players"."id"
INNER JOIN "countries" ON "players"."country"="countries"."id"
LEFT JOIN "cars" ON "car"="cars"."id"
INNER JOIN "zones" ON "zone"="zones"."id"
WHERE "scores"."id" = (SELECT id AS id FROM "scores" AS "temp" WHERE "temp"."glitch" IN ('None', 'Glitch')
AND temp.zone=scores.zone ORDER BY "temp"."multi" DESC, "temp"."score" DESC LIMIT 1)
ORDER BY "scores"."zone" ASC
Since this doesn't seem to work this way, is there another way I could proceed to get my limit (using Mysql 5 database) ?
EDIT :
Thanks for your help. Finally I figured out a way to get things done the way I want and to remove the quotes by simply remove the subquery construction and to write it directly in the where function :
$select->where('scores.id = (SELECT id FROM scores AS lookup WHERE lookup.zone = scores.zone ORDER BY multi DESC , score DESC LIMIT 1)');
Although I can continue my dev with this, I feel more like using a poor trick to get rid of this issue and so I will let this question unanswered until someone comes with a real solution there.
Anyway there might be no solution at all, since it might be an issue in ZF2 core itself.
Change the line -
$select->where(array('scores.id' => $sub));
with
$select->where(array('scores.id' => new \Zend\Db\Sql\Expression("({$sub->getSqlString($this->tableGateway->adapter->getPlatform())})"));
Try with just above change.
And if it still doesn't work then make changes to the core Select class file located at -
PROJECT_FOLDER/vendor/zendframework/zendframework/library/Zend/Db/Sql/Select.php
Line No. 921 -
Change $sql = $platform->quoteValue($limit); with $sql = $limit;
Line No. 940 -
Change return array($platform->quoteValue($offset)); with return array($offset);
I have come across the issue from github and wondered as why it is still not working with the latest ZF2 files. I know the solution given above doesn't look like the proper one but I had to somehow make it work. I have tried it and it works.
Its only a quick fix before the actual solution comes into picture.
I'm working on a Symfony2 using Doctrine.
I would like to know how to change the behavior of "findBy" functions when retrieving my entities.
For example, if you call "findAll()", it returns all products.
$entities = $em->getRepository('ShopBundle:Product')->findAll();
However, how to reduce the number of queries, because, by default, it will create a new query each time I want to get a member linked to a join column. So if I get 100 entities, it will process 101 queries (1 to get all entities and 1 by entity to get join column).
So today, I use createQuery() function by specifying the joins. Is there a way to configure something about findBy functions to skip createQuery method ?
Thanks in advance !

You can fetch out this in below way
public function findUser() {
$query = $this->getEntityManager()
->createQuery('SELECT us.id as id, us.name as user_name FROM Bundle:User us');
try {
return $query->getResult();
} catch (\Doctrine\ORM\NoResultException $e) {
return null;
}
}
Let's say I do a simple query:
$products =
Yii::app()->db->createCommand()->setFetchMode(PDO::FETCH_OBJ)
->select('*')
->from('products')
->limit(9)
->queryAll();
Let's say there are 500 products in the database. Is there a way I can get YII to automatically return the total number (count) of products if the "limit" was included? Perhaps return an object like this:
$products->products = array( ... products ... )
$products->totalProducts = 500;
The problem is, if LIMIT is included, it will return items, and the count will therefore be 9. I want a solution whereby it will return the 9 items, but also the count of say 200 items if there were 200 items.
Why not an easy:
$сount = Yii::app()->db->createCommand('select count(*) from table')->queryScalar();
echo $count;
You'll either have to run two queries (a count(*) query without the limit and then the limited query) or you can send you can retrieve your products using CSqlDataProvider and let it do it for you. But it generally takes two queries.
Note: one of the nifty features in Yii 1.1.13 is that you can send your query builder command in to the CSqlDataProvider if you're going to be using a dataprovider. More information at on this pull request that fixed it. That way, you can both use the power of query builder while also being able to shift your data into a dataprovider. Previously you had to build your SQL statement manually or grab the queryText of the command.
Yii::app()->db->createCommand('select count(*) from tbl_table')->queryScalar();
Try to use execute() instead of query() because execute returns rows count.
example:
$rowCount = $command->execute();
You could try using COUNT like this:
$dbCommand = Yii::app()->db->createCommand("
SELECT COUNT(*) as count FROM `products`");
$data = $dbCommand->queryAll();
Hope that helps!
EDIT: You might find this useful too: CDataProvider
Try this -
$sql = Yii::app()->db->createCommand('select * from tbl_table')->queryAll(); //It's return the Array
echo count($sql); //Now using count() method we can count the array.
