I'm using Laravel query builder and trying to do something like this:
$builder = DB::table('mainTable')->where("mainTable.id", "=", 111);
$builder->leftJoinSub(
DB::table('table2')
->where('table2.id', '=', DB::raw("mainTable.subtableId"))
->where('table2.region', '=', DB::raw("mainTable.region"))
->orderBy('table2.someOrder', 'DESC')
->select('kamery2.id')
->first(),
'myId',
'table2.id',
'=',
'myId'
);
And I'm getting
The multi-part identifier "mainTable.subtableId" could not be bound.
However when I write it with DB::raw('...') it works.
$builder->leftJoin(
'table2',
'table2.id',
'=',
DB::Raw("...")
);
So I'm trying to find out what I'm doing wrong. Did I make a syntactic mistake only? Or Laravel query's builder doesn't allow what I want to achieve and I have to use ->leftJoin(.... DB::raw() ) ?

I have a Laravel application with this Eloquent query:
$products = Product::where('name', 'LIKE', "%{$value}%")
->whereHas('categories', function($q) {
$q->where( 'slug', 'tonery-cartridge' );
})->with('manufacturer')
->with('sm_image')
->orderBy('created_at','DESC')
->take(10)
->get();
This code generates the sql command like:
select * from `products` where `name` LIKE '%can%'
and exists (
select * from `categories` inner join `category_product`
on `categories`.`id` = `category_product`.`category_id`
where `products`.`id` = `category_product`.`product_id`
and `slug` = 'tonery-cartridge'
)
order by `created_at` desc limit 10
I am sure there are products which name contains "can" string and which belongs to the category with slug "tonery-cartridge". Why this query returns an empty result? If I try to make inner join sql manually it works well as on the screenshot below:
I think that your queries are not equivalent. The SQL output from laravel does not join tables in it's FROM clause, but in your manually constructed SQL statement you do a lot of inner joins in your FROM clause and on the resulting table you perform your operations, which is not true for the former.
Try the following
DB::table('products')
->join('category_product', 'category_product.product_id', '=', 'products.id')
->join('categories', 'category_product.category_id', '=', 'categories.id')
->whereRaw('products.name LIKE %can% AND categories.slug = "tonery-cartridge"')
->select('products.name', 'categories.slug')
->orderBy('created_at','DESC')
->take(10)
->get()
If you want to avoid using whereRaw, you can try the following.
DB::table('products')
->join('category_product', 'category_product.product_id', '=', 'products.id')
->join('categories', 'category_product.category_id', '=', 'categories.id')
->where([
['products.name, 'LIKE', '%' . $value . '%'],
['categories.slug', '=', 'tonery-cartridge']])
->select('products.name', 'categories.slug')
->orderBy('created_at','DESC')
->take(10)
->get()
HTH
This could be one of the solutions
$category = Category::where( 'slug', 'tonery-cartridge' )->first();
$products = $category->products()
->where('name', 'LIKE', "%{$value}%")
->with('manufacturer')
->with('sm_image')
->latest()
->take(10)
->get();
DB::table('products')
->where('status', '=', 'published')
->where('sub_category', '=', 'grooming-wellness')
->where('sub_category', '=', 'beauty-care')
->get();
it doesn't work. it returns 0 data.
I am assuming you want to check if a field has a particular value or another value. You can use whereIn to achieve this:
DB::table('products')
->where('status', '=', 'published')
->whereIn('sub_category', ['grooming-wellness', 'beauty-care'])
->get();

$data = CustomerPrepaid
::join('pos_sales', 'customer_prepaid.customer_id', '=', 'pos_sales.customer_id')

'customer_prepaid.product_id', 'customer_prepaid.balance',
'last_used', 'expiry_date', 'customer_prepaid.amount as price')
->offset(($page-1)*$limit)->limit($limit)->get();
SQL
SELECT customer_prepaid.customer_id, customer_prepaid.created_at as purchase_date,
pos_sales_product.pos_sales_product_code as reference_no, customer_prepaid.product_id,
customer_prepaid.balance, customer_prepaid.amount*customer_prepaid.balance as value,
last_used, expiry_date, customer_prepaid.amount as price,
customer_prepaid.amount*customer_prepaid.balance as total
FROM customer_prepaid
JOIN pos_sales ON customer_prepaid.customer_id = pos_sales.customer_id
JOIN pos_sales_product ON pos_sales.pos_sales_code = pos_sales_product.pos_sales_code
WHERE pos_sales_product.product_id = customer_prepaid.product_id
The resulting SQL executed on the server returns the right result, but I get no eloquent result, why might that be?
Oh gosh, took me forever to realize you misused ->where.
Change your ->where to ->whereColumn:
$data = CustomerPrepaid
::join('pos_sales', 'customer_prepaid.customer_id', '=', 'pos_sales.customer_id')
->join('pos_sales_product', 'pos_sales.pos_sales_code', '=', 'pos_sales_product.pos_sales_code')
->whereColumn('pos_sales_product.product_id', 'customer_prepaid.product_id')
->select(
'customer_prepaid.customer_id',
'customer_prepaid.created_at',
'pos_sales_product.pos_sales_product_code as reference_no',
'customer_prepaid.product_id', 'customer_prepaid.balance',
'last_used', 'expiry_date', 'customer_prepaid.amount as price'
)
->offset(($page-1)*$limit)
->limit($limit)
->get();
You have to use whereColumn instead of where to make column comparison. Else it's expecting a third parameter value to be set.
Check the documentation on how to use whereColumn: https://laravel.com/docs/5.5/queries#where-clauses
I'm trying to create a self join in laravel using aliases, but it doesn't seem to want to pick it up, because I get an error saying that the columns p1.sub_menu and p2.5 are not found. Here is my join:
$menu = DB::table('pages AS p1')
->leftJoin('pages AS p2', 'p1.sub_menu', '=', 'p2.'.$id.'')->get();
Error because of your leftJoin statement
Params in leftJoin statement are columns which you want to use relationships.
$menu = DB::table('pages AS p1')->leftJoin('pages AS p2', 'p1.sub_menu', '=', **'p2.'.$id.''**)->get();
My solution is:
$menu = DB::table('pages AS p1')->leftJoin('pages AS p2', 'p1.sub_menu', '=', 'p2.sub_menu')->where("p2.menu_id", "=", $menu_id)->get();
I'm trying to translate this (My)SQL to DQL
SELECT content, created, AVG(rating)
FROM point
GROUP BY DAY(created)
ORDER BY created ASC
And I'm stuck at GROUP BY part, apparently DAY/WEEK/MONTH isn't recognized as valid "function".
[Semantical Error] line 0, col 80 near '(p.created) ORDER': Error: Cannot group by undefined identification variable.
$this->createQueryBuilder('p')
->select('p')
->groupBy('DAY(p.created)')
->orderBy('p.created', 'ASC')
Q: Is it possible to create this kind of query with query builder, or should I use native query?
It is not possible to use custom DAY/WEEK/MONTH user functions in GROUP BY queries in Doctrine 2.1.?, only SELECT queries are supported (not sure for 2.2.? branch), so I ended up using native query, and everything works fine.
Quick overview of the code:
// creating doctrines result set mapping obj.
$rsm = new Doctrine\ORM\Query\ResultSetMapping();
// mapping results to the message entity
$rsm->addEntityResult('Omglol\AppBundle\Entity\Message', 'm');
$rsm->addFieldResult('m', 'id', 'id');
$rsm->addFieldResult('m', 'content', 'content');
$rsm->addFieldResult('m', 'rating', 'rating');
$rsm->addFieldResult('m', 'created', 'created');
$sql = "SELECT id, content, AVG(rating) as rating, created
FROM message
WHERE domain_id = ?
GROUP BY WEEK(created)";
$query = $this->_em->createNativeQuery($sql, $rsm);
$query->setParameter(1, $domainId);
$query->getResult();
