COUNT value mismatch in Eloquent JOIN query of Laravel 5.2 - php

Here is my query
$allInspiration = $allInspiration->select('businesses.id as business_id','businesses.owner_name',
'businesses.user_id as business_user_id','businesses.business_name',
DB::raw("COALESCE(CONCAT(customers.cust_fname, ' ', customers.cust_lname), 'N/A') as customer_name"),
'business_reviews.id as review_master_id','business_reviews.rating',
'business_reviews.comment','business_reviews.review_image',
DB::raw("COUNT(inspiration_likes.id) as like_count"),
DB::raw("COUNT(inspiration_comments.id) as comment_count"),
'business_reviews.customer_id','business_reviews.created_at',
'business_reviews.status')
->join('businesses','business_reviews.business_id', '=', 'businesses.id')
->leftJoin('customers','business_reviews.customer_id', '=', 'customers.id')
->rightJoin('inspiration_likes','business_reviews.id', '=', 'inspiration_likes.review_id')
->rightJoin('inspiration_comments','business_reviews.id', '=', 'inspiration_comments.review_id')
->where('business_reviews.inspiration',1);
The problem is, there are two rows in "inspiration_likes" and two rows in "inspiration_comments". But my like_count and comment_count is both returning 4.
How can I solved this problem?

Use COUNT(DISTINCT) function
COUNT(DISTINCT inspiration_likes.id)
COUNT(DISTINCT inspiration_comments.id)

Why Laravel Eloquent HavingRaw returns a null value?

The following query I am trying to write in Laravel Eloquent which returns null value. I have no idea what I am doing wrong in the following query.
SQL Query::
SELECT orders.user_id FROM orders JOIN order_item ON order_item.order_id = orders.id GROUP BY orders.user_id HAVING COUNT(orders.user_id)>700
Eloquent Query Builder::
return DB::table('orders')
->join('order_item', 'order_item.id', '=', 'orders.id')
->groupBy('orders.user_id')
->select('orders.user_id')
->having(DB::raw('COUNT(orders.user_id) > 700'))
->get()
Change order_item.id to order_item.order_id and use havingRaw instead of DB::raw in having clause. See the following right query.
return DB::table('orders')
->join('order_item', 'order_item.order_id', '=', 'orders.id')
->groupBy('orders.user_id')
->select('orders.user_id')
->havingRaw('COUNT(orders.user_id) > 700')
->get()

Create subquery in NOT IN

I am using Laravel Framework 6.16.0.
I have the following sql query:
SELECT DISTINCT
`companies`.*
FROM
`companies`
LEFT JOIN `trx` ON `trx`.`companies_id` = `companies`.`id`
WHERE
`trx`.`transaction_date` >= 2020-11-12 AND companies.symbol NOT IN (SELECT DISTINCT
companies.symbol
FROM
`companies`
LEFT JOIN articles a ON a.companies_id = companies.id
WHERE
a.created_at >= 2020-11-12
ORDER BY
created_at
DESC)
ORDER BY
transaction_date
DESC
I have created the following eloquent query:
DB::connection('mysql_prod')->table('companies')->select('companies.symbol')
->leftJoin('trx', 'trx.companies_id', '=', 'companies.id')
->where('trx.transaction_date', '>=', Carbon::today()->subDays(1)->startOfDay())
->orderBy('transaction_date', 'desc')
->distinct()
->get('symbol');
However, I am not sure how to pack the in my eloquent query to get all the symbol back that should be excluded.
I highly appreciate your replies!
You should try something like this:
$date = Carbon::today()->subDays(1)->startOfDay();
DB::connection('mysql_prod')->table('companies')->select('companies.symbol')
->leftJoin('trx', 'trx.companies_id', '=', 'companies.id')
->where('trx.transaction_date', '>=', $date)
->whereNotIn('companies.symbol', function ($q) use ($date) => {
$q->select('companies.symbol')
->from('companies')
->leftJoin('articles', 'articles.companies_id', 'companies.id')
->where('articles.created_at', '>', $date)
->distinct()
->get()
})
->orderBy('transaction_date', 'desc')
->distinct()
->get();
It will provide a similar query as you mentioned.
Reference from here.
Also, you can read how to write sub Query from Laravel docs.

Query using Eloquent Laravel using "as"

How do you know the other code to get this query in laravel using eloquent?
$variable_value= DB::select(
'SELECT
sv.VARIABLE_NAME as sv_variable_name, sv.TYPE as sv_type, sv.ADDRESS as sv_address, sv.VALUE as sv_value,
ms.VARIABLE_NAME as ms_variable_name, ms.TYPE as ms_type, ms.ADDRESS as ms_address, ms.VALUE as ms_value
FROM MASTER_VARIABLES ms
JOIN SLAVE_VARIABLES sv ON ms.SLV_ADDRESS=sv.ID_VARIABLE'
);
Thank you for your help, guys!
It's all in the documentation. Give it a read?
# Selects
Specifying A Select Clause
You may not always want to select all columns from a database table. Using the select method, you can specify a custom select clause for the query:
$users = DB::table('users')->select('name', 'email as user_email')->get();
# Joins
Inner Join Clause
The query builder may also be used to write join statements. To perform a basic "inner join", you may use the join method on a query builder instance. The first argument passed to the join method is the name of the table you need to join to, while the remaining arguments specify the column constraints for the join. You can even join to multiple tables in a single query:
$users = DB::table('users')
->join('contacts', 'users.id', '=', 'contacts.user_id')
->join('orders', 'users.id', '=', 'orders.user_id')
->select('users.*', 'contacts.phone', 'orders.price')
->get();
$query = DB::table('MASTER_VARIABLES as ms')
->select(
'sv.VARIABLE_NAME as sv_variable_name',
'sv.TYPE as sv_type',
'sv.ADDRESS as sv_address',
'sv.VALUE as sv_value',
'ms.VARIABLE_NAME as ms_variable_name',
'ms.TYPE as ms_type',
'ms.ADDRESS as ms_address',
'ms.VALUE as ms_value'
)
->join('SLAVE_VARIABLES as sv', 'ms.SLV_ADDRESS', '=', 'sv.ID_VARIABLE')
->get();

How to join tables with more than one attribute match?

I am trying to turn my raw sql into laravel query builder and I encounter difficulty on how to join multiple tables using with many attributes match.
In this case, I want to join the table jr_h and jr_d with three attributes match (book,p_seq and staff_code) rather than one (book).
Raw sql:
$sql = "select from_time,to_time,t.staff_code,s.name_t as staff_name,t.book,t.p_code,t.p_seq,p.hrs1,s.img_file,
t.hrs_work,p.sharing_cnt as hrs_work, t.hrs_ot as hrs_ot from jr_d as t
inner join jr_h as p on(t.book=p.book and t.p_seq=p.p_seq and t.staff_code=p.staff_code)
inner join astaff as s on(t.staff_code=s.staff_code) ";
Laravel query builder:
$jr_d = DB::table('jr_d')
->join('jr_h', 'jr_d.book', '=', 'jr_h.book')
->join('astaff', 'jr_d.staff_code', '=', 'astaff.staff_code')
->select('jr_h.*','jr_d.*','astaff.*','astaff.name_t as staff_name')
->where('jr_d.ref_group','=','E')
->get();
and also want to know if there is a way to make the query faster since it has a lot of data in the tables.
Laravel joins with multiple conditions:
$results = DB::table('jr_d')
->select('jr_h.*','jr_d.*','astaff.*','astaff.name_t as staff_name')
->join('jr_h', 'jr_d.book', '=', 'jr_h.book')
->join('jr_h as p', function($query){
$query->on('t.book','=', p.book');
$query->on('t.p_seq','=', 'p.p_seq');
$query->on('t.staff_code', '=', 'p.staff_code');
})
->where('jr_d.ref_group','=','E')
->get();
`
Try this:
// ...
->join('jr_h p', function($join) {
$join->on('t.book', '=', 'p.book');
$join->on('t.p_seq', '=', 'p.p_seq');
// ... more conditions
});
Try this.
$jr_d = DB::table('jr_d')
->join('jr_h', 'jr_d.book', '=', 'jr_h.book')
->join('astaff', 'jr_d.staff_code', '=', 'astaff.staff_code')
->select('*','astaff.name_t as staff_name')
->where('jr_d.ref_group','=','E')
->get();

Helpe me to convert SQL query to Laravel eloquent

I have this SQL query:
SELECT *, count(*) as mostView FROM users RIGHT JOIN visitors ON users.id = visitors.user_id GROUP BY users.id HAVING users.isActive=1 AND users.fullName IS NOT NULL AND users.photo_id IS NOT NULL AND users.role_id IN(1, 3) ORDER BY mostView DESC LIMIT 5
It works, but I need convert to Laravel eloquent, i'm using laravel 5.6, could any one helpe me thanks in advance
I'm assuming that you have map the relationship in your Model if you do you can do like below,
$userViews = User::->with('vistors')
->where('isActive',1)
->whereNotNull('fullName')
->whereNotNull('photo_id')
->whereIn('role_id ',[1,3])
->get();
$mostView = $userViews->sortBy(function ($collection) {
return $collection->vistors->count()
})->take(5)
hope this helps
Not going to spoon feeding but can provide you some ideas to convert raw sql to eloquent, your sql should ideally be like this:
User::selectRaw('*', 'count(*) as mostView')
->rightJoin()
->groupBy()
->having()
->where // whereNotNull // wherIn
->orderBy()
->take(5)
->get();
Kindly refer to laravel docs: https://laravel.com/docs/5.6/queries
Thanks for all i'm studies Database: Query Builder on the link
https://laravel.com/docs/5.6/queries
and so i solved my question by myself
the answer is:
$mostViews = DB::table('users')
->rightJoin('visitors', 'users.id' , '=' , 'visitors.user_id')
->select('users.*', DB::raw('count(*) as mostView'))
->where('isActive', '=', '1')
->whereNotNull('fullName')
->where('photo_id', '<>', 'NULL')
->where(function ($q){
$q->where('role_id', '=', '1')
->orWhere('role_id', '=', '3');
})
->groupBy('user_id')
->orderBy('mostView', 'desc')->take(5)->get();
