I have this join:
Return DB::table('volunteer')
->join('volunteer_volunteer_category', 'volunteer_volunteer_category.volunteer_id', '=', 'volunteer.id')
->select(array('*','volunteer.id AS link_id'))
->where('is_published', '=', 1)
But it unsurprisingly returns duplicate records, so I try to use distinct():
Return DB::table('volunteer')
->join('volunteer_volunteer_category', 'volunteer_volunteer_category.volunteer_id', '=', 'volunteer.id')
->select(array('*','volunteer.id AS link_id'))
->distinct()
->where('is_published', '=', 1)
but I want to use distinct() on a specific single field which I'd easily be able to do in SQL. It seems distinct() does not take parameters, i.e. I can't say distinct('volunteer.id').
Can anyone point me to how can I remove my duplicate records? I bet this is another forehead slapper for me.
In my project I tried distinct() and groupby() too and both of them worked:
//Distinct version.
Company_Customer_Product::where('Company_id', '=', $companyid)->distinct()->get(array('Customer_id'));
//Goup by version.
Company_Customer_Product::where('Company_id', '=', $companyid)->groupby('Customer_id')->get(array('Customer_id'));
According to this, distinct() should work in your case too, just use it with get():
Return DB::table('volunteer')
->join('volunteer_volunteer_category', 'volunteer_volunteer_category.volunteer_id', '=', 'volunteer.id')
->select(array('*','volunteer.id AS link_id'))
->distinct()
->where('is_published', '=', 1)
->get(array('volunteer.id'));
Otherwise you don't need distinct() when you use groupby() so you could just use:
Return DB::table('volunteer')
->join('volunteer_volunteer_category', 'volunteer_volunteer_category.volunteer_id', '=', 'volunteer.id')
->select(array('*','volunteer.id AS link_id'))
->group_by('volunteer.id')
->where('is_published', '=', 1)
->get(array('volunteer.id'));

I have a query built where I'm using "with" to include related models. However, I'm not sure how to filter those related models in a where clause.
return \App\Project::with("projectLeaders")->join('companies', 'company_id', '=', 'companies.id')
->join('project_status', 'project_status.id', '=', 'projects.status_id')
->select('companies.*', 'project_status.name AS statusName', 'projects.*');
Please note the with("projectLeaders") in the query. So, ProjectLeaders is a relation that brings objects of kind Employee, how can I filter in that query those "Employees" whose attribute "Lastname" is like "Smith" ?
You can implement where class both tables. Please check following code and comments.
return \App\Proyecto::with(["projectLeaders" => function($query){
$query->where() //if condition with inner table.
}])->join('empresas', 'id_empresa', '=', 'empresas.id')
->join('tipo_estado_proyecto', 'tipo_estado_proyecto.id', '=', 'proyectos.id_tipo_estado_proyecto')
->where() //if condition with main table column.
->select('empresas.*', 'tipo_estado_proyecto.nombre AS nombreEstadoProyecto', 'proyectos.*');
You can use Closure when accessing relation using with. Check below code for more details:
return \App\Project::with(["projectLeaders" => function($query){
$query->where('Lastname', 'Smith') //check lastname
}])->join('companies', 'company_id', '=', 'companies.id')
->join('project_status', 'project_status.id', '=', 'projects.status_id')
->select('companies.*', 'project_status.name AS statusName', 'projects.*');
You may use the where method on a query builder instance to add where clauses to the query. The most basic call to where requires three arguments. The first argument is the name of the column. The second argument is an operator, which can be any of the database's supported operators. Finally, the third argument is the value to evaluate against the column.
return \App\Project::with("projectLeaders")->join('companies', 'company_id', '=', 'companies.id')
->join('project_status', 'project_status.id', '=', 'projects.status_id')
->where('lastname','=','Smith')
->select('companies.*', 'project_status.name AS statusName', 'projects.*');
Don't forget to return results with a get();
The query you have written is correct. But after building the query you need to fetch the data from database.
METHOD ONE
So adding get() method to your query:
return App\Project::with('projectLeaders')
->leftJoin('companies', 'company_id', '=', 'companies.id')
->leftJoin('project_status', 'project_status.id', '=', 'projects.status_id')
->select('companies.*', 'project_status.name AS statusName', 'projects.*')
->get();
METHOD TWO (with pagination)
return App\Project::with('projectLeaders')
->leftJoin('companies', 'company_id', '=', 'companies.id')
->leftJoin('project_status', 'project_status.id', '=', 'projects.status_id')
->select('companies.*', 'project_status.name AS statusName', 'projects.*')
->paginate(3);
My Requirements : I select baseleads table with Random Order using following conditions
beaseleads currentstatus column value have New Lead Status or
beaseleads currentstatus column value have Call Not Picking status and updated_at date is not Equal to Today Date.
My Laravel Query is below
$baseleadsData=Baseleads::inRandomOrder()->Where('process_status',0)->where(function ($query) {
$query->where('current_status','New Lead');
$query->Orwhere('current_status','Call Not Picking');
$query->OrwhereDate('updated_at', '!=', date('Y-m-d'));
})->first();
Its not Working Properly. What is my Mistake.
->where(function ($query) {
$query->where('current_status','New Lead')
->orWhere('current_status','Call Not Picking')
->orWhere('updated_at', '!=', date('Y-m-d').' 00:00:00');})->first();
It's been a while since I used Laravel, but have you tried
$query->where('current_status', '=', 'New Lead');
$query->Orwhere('current_status', '=', 'Call Not Picking');
instead of
$query->where('current_status','New Lead');
$query->Orwhere('current_status','Call Not Picking');
I'm not sure this will work as it looks like Laravel automatically makes the comparison. What is the error code youre getting? (You can turn debug mode on in your settings file)
you need to use method names in camelCase
use orWhere and orWhereDate
You did mistake of method name, use Orwhere to orWhere, OrwhereDate to orWhereDate and Where to where. and orWhereDate outside of where query.
$baseleadsData=Baseleads::inRandomOrder()
->where('process_status',0)
->where(function ($query) {
$query->where('current_status','New Lead');
$query->orWhere('current_status','Call Not Picking');
})
->orWhereDate('updated_at', '!=', date('Y-m-d'))
->first();
In laravel elequent query how to make these two where select in one.
I also feels if there too many conditions, I've too use too many where clause.
->where('trade_status', '<>', 'TRADE_FINISHED')
->where('trade_status', '<>', 'TRADE_SUCCESS')
Use whereNotIn():
->whereNotIn('trade_status', ['TRADE_FINISHED', 'TRADE_SUCCESS']);
Here in documentation you can notice
You can pass array of condition like
$users = DB::table('users')->where([
['status', '=', '1'],
['subscribed', '<>', '1'],
])->get();
for your condition it should be like
DB::table('your_table')->where([
['trade_status', '<>', 'TRADE_FINISHED'],
['trade_status', '<>', 'TRADE_SUCCESS'],
])->get();
I have a table called instructor_class: user_id, class_id and I have another table classes: id, time, active.
I would like to show classes for a single user but only those classes that active is 0 or 1.
My current code looks like this:
return InstructorClass::with('classes.session')->where('user_id', '=', $userId)->get();
This code is displaying me everything, then I tried the following code:
$active = 1;
return InstructorClass::with(['classes' => function ($q) use ($active) {
$q->where('active', '=', $active); // '=' is optional
}])
->where('user_id', '=', $userId)
->get();
This again returns me same records, but of course the class property is null for each record, which at some point looks correct, but my point is if the 'active' field does not corresponds at the classes table do not show the record, seems like the where() stm within with() is optional..
I am kinda stuck here...
Would appreciate your help, opinions!
You can use ::has('classes') to only return the models that have related classes
return InstructorClass::has('classes')->with(['classes' => function ($q) use ($active) {
$q->where('active', $active);
}])
->where('user_id', '=', $userId)
->get();
Never thought it could be this simple:
return InstructorClass::with('classes.session')
->join('classes', 'classes.id', '=', 'instructor_class.class_id')
->where('classes.active', '=', 1)
->where('user_id', '=', $userId)
->get();
I'm trying to select specific columns from two tables however when I add the ->select() method into my query, I get an error.
If I leave out the ->select() method, I get a valid resultset and everything works, but adding the select breaks it. Sadly the error reported has nothing to do with the query and is useless to me.
Here is the code that works:
$notifications = DB::table('notifications')
->join('notifications_pivot', function($join)
{
$join->on('notifications.id', '=', 'notifications_pivot.notification_id')
->where('notifications_pivot.user_id', '=', Session::get('id'))
->where('notifications_pivot.is_read', '=', 'N');
})
->get();
Now here's the code that breaks:
$notifications = DB::table('notifications')
->join('notifications_pivot', function($join)
{
$join->on('notifications.id', '=', 'notifications_pivot.notification_id')
->where('notifications_pivot.user_id', '=', Session::get('id'))
->where('notifications_pivot.is_read', '=', 'N');
})
->select(DB::raw('notifications.id, notifications.subject, notifications.message, notifications.url,
notifications.start_date, notifications.end_date, notifications.access_role_id, notifications_pivot.id,
notifcations_pivot.notification_id, notifications_pivot.user_id, notifications_pivot.is_read'))
->get();
It's times like these when I wish I could just write straight SQL and parse the query!
Any suggestions?
Take out the DB::raw() and just pass the fields you want as parameters.
If that doesn't work, the Laravel log at app/storage/logs/laravel.log may provide more insight.
$notifications = DB::table('notifications')
->join('notifications_pivot', function($join)
{
$join->on('notifications.id', '=', 'notifications_pivot.notification_id')
->where('notifications_pivot.user_id', '=', Session::get('id'))
->where('notifications_pivot.is_read', '=', 'N');
})
->select('notifications.id', 'notifications.subject', 'notifications.message', 'notifications.url', 'notifications.start_date', 'notifications.end_date', 'notifications.access_role_id', 'notifications_pivot.id', 'notifcations_pivot.notification_id', 'notifications_pivot.user_id', 'notifications_pivot.is_read')
->get();
