Doctrine QueryBuilder multiple distinct - sql

I would like to restrict results with DISTINCT on two columns using doctrine ORM
My function is like this :
public function findFdvLinkedToPdv($pointVenteCodes){
$queryBuilder =
$this->createQueryBuilder('r')
->leftJoin('r.forceVente', 'forceVente')
->leftJoin('r.pointVente', 'pointVente')
->leftJoin('r.signature', 'signature')
->leftJoin('signature.affaire', 'affaire')
->andWhere('pointVente.code IN (:pointvente_codes)')
->orderBy('forceVente.matricule', 'ASC')
->addOrderBy('pointVente.code', 'ASC')
->addOrderBy('affaire.code', 'ASC')
->addOrderBy('r.type', 'ASC')
->setParameters(array('pointvente_codes' => $pointVenteCodes,))
->select(array(
'forceVente.matricule AS forcevente_matricule',
'pointVente.code AS pointvente_code',
'affaire.code AS affaire_code',
'r.id AS id',
'r.profil AS profil',
'r.type AS type',
'forceVente.nom AS nom',
'forceVente.prenom AS prenom',
'forceVente.email AS email',
'r.deletedAt AS deletedAt'));
return $queryBuilder->getQuery()->getArrayResult();
}
For each forcevente.matricule and each pointVente.code , I have from 2 to 6 rows. I would like to get one row for each couple forcevente.matricule/pointVente.code I have to do a distinct on both columns, but when I try :
->select(array(
'DISTINCT forceVente.matricule AS forcevente_matricule',
'DISTINCT pointVente.code AS pointvente_code',
'affaire.code AS affaire_code', etc ...
I have a doctrine error ...
[EDIT]
I do this in PHP after executing the request to filter the results...
//BEGIN PATCH
$i=0;
$linkedForceVentes2 = array();
foreach ($linkedForceVentes as $item) {
if (!isset($linkedForceVentes2[$item['pointvente_code']][$item['forcevente_matricule']])){
$linkedForceVentes2[$item['pointvente_code']][$item['forcevente_matricule']] = $item;
}else{
unset($linkedForceVentes[$i]);
}
$i++;
}
//END PATCH

I finaly resolved it with a groupBy :
->groupBy('forcevente_matricule', 'pointvente_code', 'type' , 'affaire_code');
Just after the select statement.

Query giving double result instead of single

I have two tables: products and current_product_attribute_values
I have tried a join query to filter them as per attribute selected by the user but when I try this with an additional condition it gives me 2 results instead of one it is including the first one which is not matching as per query:
select * from `products` inner join `current_product_attribute_values` on `products`.`id` = `current_product_attribute_values`.`product_id` where `current_product_attribute_values`.`attribute_id` = ? or `current_product_attribute_values`.`attribute_value_id` = ? and `current_product_attribute_values`.`attribute_id` = ? or `current_product_attribute_values`.`attribute_value_id` = ? and `product_name` LIKE ?
here is my laravel Controller code :
$all = Input::all();
$q = Input::get('search_text');
$att_val = Input::get('attribute_value');
$subcat = Input::get('subcat_id');
$subcat_name = DB::table('subcategories')->where('id', $subcat)->value('subcategory_name');
$brandname = DB::table('brands')->where('subcat_id', $subcat)->value('brand_name');
$brand_id = DB::table('brands')->where('subcat_id', $subcat)->value('id');
$product_count = DB::table('products')->where('brand_id', $brand_id)->count();
if ($q != "") {
// getting multiple same name params
$query = DB::table('products');
$query->join('current_product_attribute_values', 'products.id', '=', 'current_product_attribute_values.product_id');
$j = 0;
foreach ($all as $key => $values) {
//echo 'my current get key is : ' . urldecode($key). '<br>';
if ($key == $name[$j]) {
$query->where('current_product_attribute_values.attribute_id', '=', $att_id_value[$j]);
echo'<br>';
print_r($query->toSql());
echo'<br>';
//echo '<br> key matched and have some value : <br>';
//echo count($values);
if (count($values) >= 1) {
//echo '<br> it has array inside <br>';
foreach ($values as $val) {
// or waali query in same attribute
echo'<br>';
$query->orwhere('current_product_attribute_values.attribute_value_id', '=', $val);
print_r($query->toSql());
echo'<br>';
}
}
$j++;
}
}
$records = $query->toSql();
$query->where('product_name', 'LIKE', '%' . $q . '%');
$records = $query->toSql();
print_r($records);
$products = $query->paginate(10)->setPath('');
$pagination = $products->appends(array(
'q' => Input::get('q')
));
if (count($products) > 0) {
$filters = DB::table('product_attributes')->where('subcategory_id', $subcat)->get(['attribute_title']);
} else {
$filters = array();
}
$categories = categories::where('add_to_menu', 1)->with('subcategories')->with('brands')->get();
$categoryhome = categories::where('add_to_menu', 1)->with('subcategories')->get();
return view('searchfilter')
->with('productsdata', $products)
->with('filtersdata', $filters)
->with('categories', $categories)
->with('categorieshome', $categoryhome)
->with('subcat_name', $subcat_name)
->with('subcat_id', $subcat)
->with('brandname', $brandname)
->with('product_count', $product_count)
->with('querytext', $q);
}
return 'No Details found. Try to search again !';
its easier if you use raw sql as calling db select function. ex:
$query=DB::select("select * from `products` inner join `current_product_attribute_values` on `products`.`id` = `current_product_attribute_values`.`product_id` where `current_product_attribute_values`.`attribute_id` = ? or `current_product_attribute_values`.`attribute_value_id` = ? and `current_product_attribute_values`.`attribute_id` = ? or `current_product_attribute_values`.`attribute_value_id` = ? and `product_name` LIKE ?
");
indeed you can concat vars in raw sql if you need to, ex:
$queryBrands = "select id from brands where subcat_id =".$subcat;
//echo $queryBrands
$queryBrands = DB::select($queryBrands);
By looking at your tables, product table with id value 17 has two records in table current_product_attribute_values in column product_id (I assume this column is used as foreign key to product table).
With select *, you select all of the columns from both tables. So it would most likely cause your query to return multiple records.
My suggestions:
Only select the columns you need. Avoid using select * in the long run, i.e. select product.id, product.description, current_product_attribute_values.attribute_values ......
Make use of GROUP BY
Hope these helps.

Laravel/SQL: where column Equals NOT and NULL

LARAVEL 5.4 (but probably it's a more general SQL question)
Hello! I have a table with a structure:
Suppose it's my model 'Table'.
I want a query which:
uses (receives) variables :
$id of array ['id', 'string', integer]
where string is '<' or '>'
$status_not_bad = bool;
(if true - include all rows where 'status' !== 'bad' AND 'status' IS NULL);
for example, we are given:
$id = [['id', '>', 0]];
$status_not_bad = true;
Table::thisquery() ... ->get();
"get rows where status is not bad and id > 0" returns rows 1 and 3.
but if we given:
$id = [['id', '<', 3]];
$status_not_bad = true;
Table::thisquery() ... ->get();
"get rows where status is not bad and id < 3" returns row 1
(it should be same query which return those results using those variables).
Probably you end with something like this:
if ($status_not_bad) {
$nStatus = 'bad';
} else {
$nStatus = 'good';
}
Table::thisquery()->where('status', '<>', $nStatus)
->whereNotNull('status')
->where($id[0], $id[1], $id[2])
->get();
But it would be a good idea to check $id keys first.
Since row id = 3 you need <= in your where statement to have that row included in the result set
$id = ['id', '<=', 3];
So, I this works:
$chain = Sample::when($status_not_bad, function($query){
return $query->where('status', '<>', 'bad')
->orwhereNull('status');
})
->where([$id])
->get();

Conditions in JOINed tables shows error CakePHP

I have two tables employee_personals where all the personal record of the employee is stored and telephone_bills where the telephone bills paid to a particular employee is stored for each month. Now in my employeePersonalsController.php I have a function called api_show_employees() which is similar to below :
function api_show_employees() {
//$this->autoRender = false;
//Configure::write("debug",0);
$office_id = '';
$cond = '';
if(isset($_GET['office_id']) && trim($_GET['office_id']) != '') {
$office_id = $_GET['office_id'];
$cond['EmployeePersonal.office_id'] = $office_id;
}
if(isset($_GET['telephoneBillTo']) && isset($_GET['telephoneBillFrom']) ) {
if($_GET['telephoneBillTo'] != '' && $_GET['telephoneBillFrom'] != '') {
$cond['TelephoneBill.bill_from'] = $_GET['telephoneBillFrom'];
$cond['TelephoneBill.bill_to'] = $_GET['telephoneBillTo'];
}
}
$order = 'EmployeePersonal.name';
// $employee = $this->EmployeePersonal->find('all');
$employee = $this->EmployeePersonal->find('all',array('order' => $order,'conditions'=>$cond));
//return json_encode($employee);
}
This functions basically finds all the employees who paid bills in the given period. But I am getting an error
Error: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'TelephoneBill.bill_from' in 'where clause'
Models : EmployeePersonal.php:
var $hasMany = array(
'TelephoneBill' => array(
'className' => 'TelephoneBill',
)
);
TelephoneBill.php
public $name = 'TelephoneBill';
var $hasMany = array('EmployeePersonal');
NB: If I skip the bill_from and bill_to conditions, I am getting the results , with TelephoneBill array !
TLDR: use Joins instead.
Details/Notes:
1) it looks like you're using recursive. Don't do that. Use Containable instead.
2) You can't limit the parent model based on conditions against data from a contained/recursive-included table - instead, use Joins.
2b) Or, you could query from the other direction, and query your TelephoneBill with conditions, then contain the EmployeePersonal.

How to select items by providing where clause in pivot

This is my code looks like right now :
$result = Category::with(array(
"getProducts",
"getProducts.getBrand",
"getProducts.getImages",
"getProducts.getDetail",
"getProducts.getTax",
"getProducts.getDiscount",
"getProducts.getAttributes" => function($query) use($_temp){
if($_temp != null){
$query->where_in('attributes.id',$_temp);
}
},
"getSlideshow",
"getSlideshow.getItems",
"getAttributeListing",
"getAttributeListing.getAttributes",
"getAttributeListing.getAttributes.productSpecific"
))
->where('id','=', $category_id)
->first();
Yet, It only filters the getProducts.getAttributes items not the 'getProducts' itself. Is there a way that I can get the Products by attributes?
Note: I am using Laravel 3

Doctrine query with ManyToMany relation

I have a simple relation ManyToMany between two entities "article" and "category" (for a blog). I would like to fetch every article with a particular category, but I don't know how to create that query. What I did is :
$query = $em->createQuery(
'SELECT u
FROM SiteBlogBundle:article u
WHERE u.categorie.name = :cat
ORDER BY u.date DESC'
)
->setParameter('cat', '$cateogory')
The line WHERE u.categorie.name = :cat doesn't work. How can I achieve that?
If you are okay with using a query-builder for better readability instead of DQL:
$articles = $em
->getRepository('SiteBlogBundle:Article')
->createQueryBuilder('article')
->leftJoin('article.category', 'category')
->where('category.name = :category_name')
->orderBy('article.date', 'DESC')
->setParameter('category_name', $category->getName())
->getQuery()
->getResult()
;
But i would strongly advise you to put this query into the repository like this:
// ArticleRepository.php
public function findArticlesByCategoryName($name)
{
return $this->createQueryBuilder('article')
->leftJoin('article.category', 'category')
->where('category.name = :category_name')
->orderBy('article.date', 'DESC')
->setParameter('category_name', $name)
->getQuery()
->getResult()
;
}
Then inside your controller just do:
public function getArticles(Category $category)
{
$em = $this->getDoctrine()->getEntityManager();
return $em->
getRepository('SiteBlogBundle:Article')
->findArticlesByCategoryName($category->getName())
;
}
