I have a query that works but I need to get it into the Query Builder:
RIGHT JOIN (tlkpSUDesc RIGHT JOIN tblSU ON tlkpSUDesc.SUDescCode = tblSU.SUDescCode) ON tlkpSUTyp.SUTypCode = tblSU.SUTypCode
I can figure out how to do it. I tired this:
->rightJoin('tlkpSUDesc', function($join) {
$join->on('tblSU', 'tlkpSUDesc.SUDescCode', '=', 'tblSU.SUDescCode');
}
'tlkpSUTyp.SUTypCode', '=', 'tblSU.SUTypCode')
But that didn't work. I also tried
->rightJoin('tlkpSUDesc', 'tlkpSUTyp.SUTypCode', '=', 'tblSU.SUTypCode')
->rightJoin('tblSU', 'tlkpSUDesc.SUDescCode', '=', 'tblSU.SUDescCode')
But that didn't work either.
Thanks!
I agree with #matiaslauriti that there's nothing wrong with reaching for raw expressions. But, since you asked and it can be done with the query builder, try this:
$query = \DB::query();
$query->rightJoin('tlkpSUDesc', function ($query) {
$query->rightJoin('tblSu', 'tlkpSUDesc.SUDescCode', '=', 'tblSU.SUDescCode')->on(
'tlkpSUTyp.SUTypCode', '=', 'tblSU.SUTypCode');
})->toSql();

I have a laravel eloquent db query that I would like to return results based on chained join.
$replies = DB::table('model_replies')
->join('support_tickets', function($join){
$join->on('model_replies.model_id', '=', 'support_tickets.id');
$join->where('model_replies.model', '=', DB::raw('"SupportTicket"'));
})
->join('produce_requests', function($join){
$join->on('model_replies.model_id', '=', 'produce_requests.id');
$join->where('model_replies.model', '=', DB::raw('"ProduceRequest"'));
})
->get();
I followed the example from the docs here.
The problem is when I chain the join statements as suggested here my query gives no results.
A single join works just fine. But I need to be able to chain several of them.
What could I be doing wrong?
Thank you!
If I understood it correctly. You want to get support_tickets for those model_replies where model_replies.model = SupportTicket
DB::table('model_replies')
->leftJoin('support_tickets', function($join){
$join->on('model_replies.model_id', '=', 'support_tickets.id');
$join->on('model_replies.model', '=', DB::raw('"SupportTicket"'));
})
->leftJoin('produce_requests', function($join){
$join->on('model_replies.model_id', '=', 'produce_requests.id');
$join->where('model_replies.model', '=', DB::raw('"ProduceRequest"'));
})
->get();
I'm trying to get this MySQL query to work in laravel 5.7 query builder.
It works fine in phpmyadmin
SELECT c.Symbol
, s.SectorName
, cprs.strenght
, s.parentid
, ssbpi.Risklevel
, ssbpi.ColumnType
FROM Companies AS c
JOIN Sectors AS s ON s.SectorID = c.SectorID
JOIN Company_PriceRS AS cprs ON cprs.CompanyID = c.CompanyID
JOIN SubSectorsBPIsData AS ssbpi ON ssbpi.subcategoryid = s.parentid
WHERE cprs.PostDate = '2017-05-08'
AND WHERE CompanyPriceRS.strenght = 'strong'
AND WHERE SubSectorsBPIsData.ColumnType = $ColumnType
ColumnType is a variable that comes from a dropdown and it's already being captured and working properly.
I have tried the normal way according to documentation:
$Completequerytry1 = DB::table('Companies')
->join('Sectors', 'Sectors.SectorID', '=', 'Companies.SectorID')
->join('CompanyPriceRS', 'CompanyPriceRS.CompanyID', '=', 'Companies.CompanyID')
->$join('SubSectorsBPIsData ', 'SubSectorsBPIsData.subcategoryid', '=', 'Sectors.parentid')
->where('CompanyPriceRS.strenght', '=', 'strong')
->where('SubSectorsBPIsData.ColumnType', '=', $ColumnType)
->where('CompanyPriceRS.Postdate', '=', '2017-05-08');
->select('Companies.Symbol', 'Sectors.SectorName', 'CompanyPriceRS.strenght', 'Sectors.parentid', 'SubSectorsBPIsData.subcategoryid','SubSectorsBPIsData.ColumnType')
->limit(10);
->select('Companies.Symbol', 'Sectors.SectorName', 'CompanyPriceRS.strenght', 'Sectors.parentid', 'SubSectorsBPIsData.subcategoryid','SubSectorsBPIsData.ColumnType')
->limit(10);
echo '<pre>';
print_r($Completequerytry1);
Error:
Symfony\Component\Debug\Exception\FatalThrowableError thrown with message "syntax error, unexpected '->' (T_OBJECT_OPERATOR)"
Using functions With several nested joins:
$Completequerytry1 = DB::table('Companies')
->join('Sectors', function ($join) use ($ColumnType) {
$join->on('Sectors.SectorID', '=', 'Companies.SectorID')
->join('CompanyPriceRS', function ($join2) {
$join2->on('CompanyPriceRS.CompanyID', '=', 'Companies.CompanyID')
->join('SubSectorsBPIsData', function ($join3) {
$join3->on('SubSectorsBPIsData.subcategoryid', '=', 'Sectors.parentid')
->where(function ($query1) {
$query1->where('CompanyPriceRS.strenght', '=', 'strong') //filter 1
->where('SubSectorsBPIsData.ColumnType', '=', $ColumnType) //filter2
->where('CompanyPriceRS.Postdate', '=', '2017-05-08'); // filter 3
});
});
});
})
->select('Companies.Symbol', 'Sectors.SectorName', 'CompanyPriceRS.strenght', 'Sectors.parentid', 'SubSectorsBPIsData.subcategoryid','SubSectorsBPIsData.ColumnType')
->limit(10);
echo '<pre>';
print_r($Completequerytry1);
Error:
ErrorException (E_NOTICE)
Undefined variable: ColumnType
3: Then tried functions with nested WHERE
$Completequerytry1 = DB::table('Companies')
->join('Sectors', 'Sectors.SectorID', '=', 'Companies.SectorID')
->join('CompanyPriceRS', 'CompanyPriceRS.CompanyID', '=', 'Companies.CompanyID')
->$join('SubSectorsBPIsData ', 'SubSectorsBPIsData.subcategoryid', '=', 'Sectors.parentid') //ERROR IS GIVEN ON THIS LINE
->where(function ($query1) {
$query1->where('CompanyPriceRS.strenght', '=', 'strong')
->where('SubSectorsBPIsData.ColumnType', '=', $ColumnType)
->where('CompanyPriceRS.Postdate', '=', '2017-05-08');
});
->select('Companies.Symbol', 'Sectors.SectorName', 'CompanyPriceRS.strenght', 'Sectors.parentid', 'SubSectorsBPIsData.subcategoryid','SubSectorsBPIsData.ColumnType')
->limit(10);
echo '<pre>';
print_r($Completequerytry1);
Error:
Undefined variable: join
Still don't know what i'm missing.
Should i create functions for the JOINs and the WHEREs ?
Running out of ideas. Thanks in advance for your insights :)
It turns out that the query was being sent to a variable directly from the controller, not to the view.
I was doing this only for testing but it was using too much memory with print_r(); function making impossible to get a result. Even when using dd(); i wasn't getting what i wanted (I think it's because some sintax errors i had).
So i passed the final variable to the view and it works fine since laravel could handle the data differently.
Also i used ->limit(10); to split the results and avoid memory overload.
Here is the final code working:
$Completequerytry1 = DB::table('Companies')
->join('Sectors', 'Sectors.SectorID', '=', 'Companies.SectorID')
->join('Company_PriceRS', 'Company_PriceRS.CompanyID', '=', 'Companies.CompanyID')
->join('SubSectorsBPIsData', 'SubSectorsBPIsData.subcategoryid', '=', 'Sectors.parentid')
->select('Sectors.SectorName', 'Companies.Symbol', 'Company_PriceRS.strenght', 'Sectors.parentid', 'SubSectorsBPIsData.Risklevel','SubSectorsBPIsData.ColumnType')
->where('Company_PriceRS.strenght', '=', 'strong')
->where('SubSectorsBPIsData.ColumnType', '=','X')
->where('Company_PriceRS.Postdate', '=', '2017-05-08')
->limit(10)
->get();
return view('besttrades2', array('Completequerytry1' => $Completequerytry1)); //sending my query variable to the view
Then in the view only used:
<?= $Completequerytry1; ?>
or show it in whatever way you want.
Sometimes it's better to have another project only for testing separately.
I have two table 1)clients 2)orders. I trying to make leftjoin but I not getting correct result what i want. Please see image below.
Thanks
ClientController.php
$clients = Client::leftjoin('orders','orders.client_id','=','clients.id')
->select(DB::raw("count(orders.id) as orderCount"),
'clients.name as name','clients.email as email',
'clients.phone as phone','clients.country as country',
'orders.total_amount')
->where('orders.status',0)
->get();
$myevents = DB::table('users')
->join('event_model_user', 'users.id', '=', 'event_model_user.user_id')
->rightJoin('events', 'event_model_user.event_model_id', '=', 'events.id')
->where('users.id','=',$user->id)
->orWhere('events.bookable','=',$user->zipcode)
->get();
this is an example of i used a right join to get the events where no user has done any booking!
in your case this would be something like (not tested)
$myevents = DB::table('clients')
->leftJoin('orders','orders.client_id','=','clients.id')
->where('orders.status',0)
->get();
I have this sql (MariaDB) query, it works ok:
SELECT
admin_combustibles.nombre,
admin_combustibles.id_combustible,
admin_combustible_unidades.nombre AS unidades,
admin_tipo_combustibles.nombre AS tipo_combustible,
admin_indice_combustibles.valor_combustible
FROM
admin_combustibles
INNER JOIN admin_combustible_unidades ON admin_combustibles.combustible_unidades_id = admin_combustible_unidades.id_combustible_unidad
INNER JOIN admin_tipo_combustibles ON admin_combustibles.tipo_combustible_id = admin_tipo_combustibles.id_tipo_combustible
LEFT JOIN admin_indice_combustibles ON admin_combustibles.id_combustible = admin_indice_combustibles.combustible_id
AND admin_indice_combustibles.anio = 1992
AND admin_indice_combustibles.mes = 6
ORDER BY
admin_combustibles.nombre
But when I try to make it through Laravel, I have some error because Laravel put some on the number 1992, in that way the query doesn't work.
Plus, I don't know how to do the AND on Laravel, I only have orOn but it doesn't work:
$datos = AdminCombustible::select([
'admin_combustibles.nombre',
'admin_combustibles.id_combustible',
'admin_combustible_unidades.nombre AS unidades',
'admin_tipo_combustibles.nombre AS tipo_combustible',
'admin_indice_combustibles.valor_combustible'])
->join('admin_combustible_unidades', 'admin_combustibles.combustible_unidades_id', '=', 'admin_combustible_unidades.id_combustible_unidad')
->join('admin_tipo_combustibles', 'admin_combustibles.tipo_combustible_id', '=', 'admin_tipo_combustibles.id_tipo_combustible')
->leftJoin('admin_indice_combustibles', function ($join) {
$join->on('admin_indice_combustibles.combustible_id', '=', 'admin_combustibles.id_combustible')->orOn('admin_indice_combustibles.anio', '=', 1992);
})
->get();
dd($datos);
I got an sql syntax error.
Any help on how to make that query with query builder of Laravel? (I put the entire query as DB::raw and it works, but I don't want to use raw() )
I think there might be two problems here. Since you are using and in your original query, you might be needing to use or instead of orOn on your join.
Also you will need to use DB::raw() on the parameters, otherwise Laravel will consider them columns....
$join->on('admin_indice_combustibles.combustible_id', '=', 'admin_combustibles.id_combustible')->on('admin_indice_combustibles.anio', '=', DB::raw('1992'));
Question
How do I put a limit on one of the rows in an Eloquent result?
Scenario
I need to retrieve only around 100 characters from one of the fields in my result. Currently I'm using a join statement so multiple results are being returned. I basically need only the first 100 characters from post.content
Code
public function getAll()
{
return Post::select('posts.id', 'posts.title', 'posts.content', 'posts.views', 'posts.comments', 'posts.tags', 'posts.date_created', 'users.image_url', 'users.username', 'users.toxick')
->join('users', 'posts.user_id', '=', 'users.id')
->get();
}
I'm not sure how to go about putting a filter on the query to only return 100 characters. I've looked around briefly but I've not found anything useful, not to my specific scenario at least.
Cant test this at the moment (sorry) but what about:
public function getAll(){
$query = Post::select('posts.id', 'posts.title', 'posts.content','posts.views', 'posts.comments', 'posts.tags', 'posts.date_created', 'users.image_url', 'users.username', 'users.toxick')
->join('users', 'posts.user_id', '=', 'users.id')
->get();
foreach($query as $entries){
$entries->content = substr($entries->content, 1, 100);
}
return $query;
}
