How can I convert the following query into a laravel eloquent query?
SELECT demand_costings.pr_number as Demand_Costing,work_types.work_types,
SUM(demand_costings.pr_quantity_in_pcs) as Total
FROM demand_costings
INNER JOIN work_types
ON demand_costings.worktype_id=work_types.id
GROUP BY work_types.work_types;
You can use laravel's DB facade:
$data = DB::table('table_name')
->select(DB::raw('emand_costings.pr_number as Demand_Costing,work_types.work_types,SUM(demand_costings.pr_quantity_in_pcs) as Total FROM demand_costings INNER JOIN work_types ON demand_costings.worktype_id=work_types.id'))
->groupBy('work_types')
->get();
Try this:
DB::table('demand_costings')
->select([
'pr_number as Demand_Costing',
'work_types',
'SUM(pr_quantity_in_pcs) as Total'
])
->join('work_types', 'demand_costings.worktype_id', '=', 'work_types.id')
->groupBy('work_types.work_types')
->get();

I have no idea how to write it in Laravel Query Builder. Here's the SQL query:
select l.id, l.title, is1.similarity
FROM l
left join is1 on (l.id = is1.listing_id1 and is1.listing_id2 = 225678) or (l.id = is1.listing_id2 and is1.listing_id1 = 225678)
If I simply translate your SQL query to Laravel Query Builder query It would look like this.
DB::table('l')->select('l.id', 'l.title', 'is1.similarity')
->leftJoin('is1', function ($leftJoin) {
$leftJoin->on('l.id', '=', 'is1.listing_id1')->where('is1.listing_id2', '=', '225678')
->orOn('l.id','=', 'is1.listing_id2')->where('is1.listing_id1','=', '225678'); })
->get();
I guess, it would be something like this:
DB::table('l')
->('l.id', 'l.title', 'is1.similarity')
->join('is1', function ($join) {
$join->on('l.id', '=', 'is1.listing_id1') ->where('is1.listing_id2', '=', '225678')
->orOn('l.id','=', 'is1.listing_id2')->where('is1.listing_id1', '=', '225678');
})->get();
Don't forget to import this:
use Illuminate\Support\Facades\DB;

I am trying to convert a query to eloquent or find a way to use it in a laravel controller.
The query is:
select employee, workdate, sum(actualhours)
from ts_data group by employee, workdate;"
Using Eloquent Model :
$records = TsData::select(
'employee',
'workdate',
\DB::raw('sum(actualhours) as sumhours')
)
->groupBy('employee', 'workdate')
->get();
or using DB Facade :
$records = \DB::table('ts_data')->select(
'employee',
'workdate',
\DB::raw('sum(actualhours) as sumhours')
)
->groupBy('employee', 'workdate')
->get();
I have the following raw SQL query:
select a.id user_id, a.email_address, a.name_first, a.name_last, count(b.id) number_of_videos, sum(b.vimeo_duration) total_duration, sum(b.count_watched) total_playbacks
from users a,
videos b
where a.id = b.tutor_id
and a.email_address in ('candace_rennie#yahoo.com', 'tjm#hiltoncollege.com', 'matthewjameshenshall#gmail.com', 'nkululeko#syafunda.co.za', 'khulile#syafunda.co.za', 'nzakheni#syafunda.co.za')
group by a.id;
This correctly gets 6 rows from the database. I'm trying to convert this to a Laravel database query like so:
$totals = DB::table('users')
->select(DB::Raw('users.id as user_id'), 'users.email_address', 'users.name_first', 'users.name_last', DB::Raw('count(videos.id) as number_of_videos'), DB::Raw('sum(videos.vimeo_duration) as total_duration'), DB::Raw('sum(videos.count_watched) as total_playbacks'))
->join('videos', 'users.id', '=', 'videos.tutor_id')
->where('users.id', 'videos.tutor_id')
->whereIn('users.email_address', array('candace_rennie#yahoo.com', 'tjm#hiltoncollege.com', 'matthewjameshenshall#gmail.com', 'nkululeko#syafunda.co.za', 'khulile#syafunda.co.za', 'nzakheni#syafunda.co.za'))
->groupBy('users.id')
->get();
This however return 0 rows. Is there anything I'm missing?
It should be smth like below even tho groupBy user id does not help much as id is unique.
$aggregates = [
DB::raw('count(b.id) as number_of_videos'),
DB::raw('sum(b.vimeo_duration) as total_duration'),
DB::raw('sum(b.count_watched) as total_playbacks'),
];
$simpleSelects = ['users.email_address', users.id, 'users.name_first', 'users.name_last'];
$emails = ['candace_rennie#yahoo.com', 'tjm#hiltoncollege.com'....]
$users = Users::select(array_merge($simpleSelects, $aggregates))
->leftJoin('videos as b', function ($join) use ($emails) {
$join->on('b.tutor_id', 'a.id')
->whereIn('users.email_address', $emails);
})
->groupBy('users.id')
->get();
Try to remove this line:
->where('users.id', 'videos.tutor_id')
List item
after sql code convert into laravel
DB::select('posts.id','posts.title','posts.body')
->from('posts')
->where('posts.author_id', '=', 1)
->orderBy('posts.published_at', 'DESC')
->limit(10)
->get();
I am trying to write the following sql query in laravel:
select
`workers`.`first_name`,
`workers`.`last_name`,
`occupations`.`approval_date`,
`occupations`.`certification_date`,
`occupations`.`expiration_date`,
`occupations`.`type`,
`workers`.`photo`
from `worker_print_queue`
inner join `workers` on `worker_print_queue`.`worker_id` = `workers`.`id`
inner join `occupations` on `worker_print_queue`.`certification` = `occupations`.`type` AND `workers`.`id` = `occupations`.`worker_id`
I have written it in eloquent in the following manner:
$records = \DB::table('worker_print_queue')
->join('workers', 'worker_print_queue.worker_id', '=', 'workers.id')
->join('occupations', function($join){
$join->on('workers.id', '=', 'occupations.worker_id')
->where('worker_print_queue.certification', '=', 'occupations.type');
})
->select('workers.first_name', 'workers.last_name', 'occupations.approval_date',
'occupations.certification_date', 'occupations.expiration_date', 'occupations.type', 'workers.photo')
->get();
But I am receiving no results. I'm sure there is something I'm missing, just not sure what it is.
The issue is that this line
->where('worker_print_queue.certification', '=', 'occupations.type');
is comparing the column 'worker_print_queue.certification' to the value 'occupations.type'.
If you change it to use the on clause you should be fine:
->on('worker_print_queue.certification', '=', 'occupations.type');
I have the following sql query
SELECT * FROM exams WHERE exams.id NOT IN (SELECT examId FROM testresults)
how can I convert it into Laravel query builder format?
Thanks.
You can use whereNotIn with a closure:
$result = DB::table('exams')->whereNotIn('id', function($q){
$q->select('examId')->from('testresults');
})->get();
with Eloquent :
$result = Exams::whereNotIn('id', function($q){
$q->select('examId')->from('testresults');
})->get();
