How to convert this MySQL query to Laravel? - php

Here my MySQL query (work in phpMyAdmin) :
SELECT workcenter, (SUM(w1+w2 +w3 +w4)/ (COUNT(DISTINCT(teknisi))*40*4) )*100 AS total FROM `team` GROUP by workcenter ORDER BY total
then, i try in Laravel Sintax like this below (not work) :
$sql = Team::groupBy('workcenter')->select('workcenter', \DB::raw('(SUM(w1+w2+w3+w4)/ (COUNT(DISTINCT(teknisi))*30*4) )*100 AS total'))
->OrderBy('total', 'Desc')
->get();
When i run the laravel sintax, its doesn't show any errors, but the output is nothing..
Please anyone help me to convert the MySQL query to Laravel Sintax. Thank you!

I think you are close enough, however, this doesn't look like a correct way to group by with Eloquent ORM. Try using raw expressions, something like this might work:
$sql = DB::table('team')
->select(DB::raw('workcenter, (SUM(w1+w2 +w3 +w4)/ (COUNT(DISTINCT(teknisi))*40*4) )*100 as total'))
->orderBy('total', 'desc')
->groupBy('workcenter')
->get();

Whenever I want to convert SQL query to Laravel I always change one column name, the laravel error report will show your current query and u can compare it to the SQL query

Laravel Eloquent Where not working after joining table

Hi I have written a little query which doesnt seem to working when I use Eloquent but works when I write something similar in MySQL. Data isnt being retuned which shouldnt be due to my where clauses.
I have written this query which isnt working as expected -
$invoices = Invoice::leftJoin('user_details', 'invoices.user_id', 'user_details.user_id')
->where('invoices.practice_id', '!=', 'user_details.practice_id')
->first();
It is returning data where the invoice.practice_id = user_details.practice_id
I altered the query to prove it isnt working -
$invoices = Invoice::select('invoices.practice_id', 'user_details.practice_id')
->leftJoin('user_details', 'invoices.user_id', 'user_details.user_id')
->where('invoices.practice_id', '!=', 'user_details.practice_id')
->first();
The values returned the practice_id is 6, 6 which shouldnt be possible due to the following where clause where('invoices.practice_id', '!=', 'user_details.practice_id')
Have I done something wrong which I am just not seeing?
Thank you for any help you can provide!
UPDATE
Here is the DB schema for the invoice table
Here is the the DB schema fro the user_details table
The expected result is mentioned above, no results should be returned if invoice_practice_id = user_details.practice_id
#Luke Rayner
Try by rewriting line ->leftJoin('user_details', 'invoices.user_id', 'user_details.user_id')
to
->leftJoin('user_details', 'invoices.user_id', '=', 'user_details.user_id')
If not try to print Last query and post it

how to group by in db query builder to get the unique value?

Can someone help me to convert the below mysql to laravel db query builder or eloquent?Here is my mysql
SELECT max(created_at), jobseeker_id,call_reason,type_of_call
FROM calllogs
GROUP BY jobseeker_id
ORDER BY created_at DESC;
Here is my tries, but no luck yet.
$jobseekers =DB::table('calllogs')
->select(DB::raw("max('created_at'),jobseeker_id"))
->groupBy('jobseeker_id')
->orderBy('created_at','desc')
->get();
dd($jobseekers);
Please help me out.
$jobseekers =DB::table('calllogs')
->select(DB::raw("max(created_at),jobseeker_id"))
->groupBy('jobseeker_id')
->orderBy('created_at','desc')
->get();
Try with this code.
Only delete ' ' in max.
It will work well.
DB::table(calllogs)
->select(DB::raw('max(created_at) as max_created_at'),
'jobseeker_id','call_reason','type_of_call')
->groupBy('jobseeker_id')
->orderBy('max_created_at', 'DESC')
->get(); =>As a array.
->first(); => As a object.
Additionally, If you are using table joins see below.
->join('table_1','table_1.id','=','table_2.table_1_id')
->leftjoin('table_1','table_1.id','=','table_2.table_1_id')
->rightjoin('table_1','table_1.id','=','table_2.table_1_id')
ORDER BY clause is not in GROUP BY clause and contains nonaggregated column 'myapp.calllogs.created_at'
Two solution for that error
1.In config/database.php file make sql strict mode to false.
(or)
2. IN groupBy Clause add all your table colums.
example:
->groupBy('jobseeker_id','jobseeker_name','jobseeker_email')

Add custom field during select mysql in laravel query

I have this query in laravel 5.2
$obj_custom_stdy_data = QstCustomStudyData::where('student_id', $this->data_user['student_id'])
->select($list_id . ' as list_id ', 'chapter_id', 'subject_id', 'subject_code_id')
->get()
->toArray();
Well I have a fixed value $list_id got from top code. Actually I want to add new field during query selection as list_id. However I got error for such that method.
When I tried in mysql IDE for example:
SELECT (1+2) as total, c.* FROM users
Then the result is no wrong at all.
Is that anyway to write in query builder for laravel instead of raw style?
You can take the use of DB::raw() method of QueryBuilder like this:
->select(DB::raw('(1+2) as total'));
See more about Query Builder's Raw Expressions
Hope this helps!

Get date from timestamp in laravel

How can I get date from "2015-07-31 06:03:21" using Laravel query builder?
In normal query using DATE() we can get date easily, but I don't know how to use DATE() in Laravel query builder. Please check my code sample given below and correct me?
Normal Query
SELECT DATE('2015-07-31 06:03:21'), customer_id FROM customer_histories
Laravel Query Builder
$customerhistory = Customerhistory::where('customer_id', 1)
->select('freetext', 'DATE(created_at)')
->get();
You can do this with DB::raw(), though if you are only selecting it, why not just take created_at complete? By default, Eloquent will convert the created_at and updated_at columns to instances of Carbon so you can handle it like this in your code:
$customerhistory = Customerhistory::where('customer_id', 1)
->select('freetext', 'created_at')
->get();
dd($customerhistory[0]->created_at->toDateString());
You can use DB::raw('something') for that. In this case your raw input will be treated as part of actual SQL.
This is something you might wanna give a try:
$customerhistory = Customerhistory::where('customer_id', 1)
->select('freetext', DB::raw('DATE(`created_at`)'))
->get();
More details and yet another example cal be found here.
Also it looks like you're using eloquent. You might wanna check the mutators section.
$customerhistory = Customerhistory::where('customer_id', '=', '1')
->select('freetext', DB::raw('DATE(`created_at`)'))
->get();
Thanks.

Proper SQL to Laravel ORM

I am newbie on Laravel, I have a proper SQL Statement (which works on PHPMyAdmin and Navicat) and I can get results. What i want to do is, I want to take that statements in Laravel without using DB::raw();.
Any Helps will be appreciated.
Select
rmm.message,
count(rmm.message) as number,
receivedTime as time
FROM
rcs rcs, rmm rmm
WHERE
rmm.smsCid = rcs.smsCid AND rmm.receivedTime LIKE '%2013-04-01%' AND length('rmm.message') > '3'
GROUP BY(rmm.message)
Alternatively you can use the Fluent Query Builder. Here's my attempt, of course it's not checked as I don't have your data structure to hand. Hopefully enough to get you started:
DB::table('rcs') // SELECT FROM rcs
->join('rmm', 'rmm.smsCid', '=', 'rcs.smsCid') // Simple INNER join
->where('rmm.receivedTime', 'LIKE', '%2013-04-01%')
->where(DB::raw('LENGTH(rmm.message)'), '>', 3)
->get(array(DB::raw('COUNT(rmm.message)'), 'rmm.message', 'receivedTime')); // Get only the columns you want
You can use DB::query() to run your query. This calls the query method on the active DB connection.
