How to convert a specific query into Laravel Query syntax - php

I'm trying to change the following query to laravel :
SELECT
*
FROM
usrusrs uu
,posts p
WHERE
(
uu.user_id = $u_id
or
uu.friend_id = $u_id
)
and
(
uu.user_id = p.user_id
OR
uu.friend_id = p.user_id
)
I tried the following, but it's giving different output. I think there might be something wrong with the joining between the two tables. any suggestions ?
$usrusrmembs = DB::table('usrusrs')
->join('posts', 'posts.user_id', '=', 'usrusrs.user_id')
->orwhere('posts.user_id', '=', 'usrusrs.friend_id')
->where('usrusrs.user_id', $u_id)
->orwhere('usrusrs.friend_id', $u_id)
->get();


Got it after some digging :
$usrusrmembs = DB::table('usrusrs')
->join('posts', function ($join) {
$join->on('posts.user_id', '=', 'usrusrs.user_id')->orOn('posts.user_id', '=', 'usrusrs.friend_id');
})
->where('usrusrs.user_id', $u_id)
->orwhere('usrusrs.friend_id', $u_id)
->get();

Laravel 5.4 query builder having issues with groupBy

I'm trying to convert this query to query builder in Laravel 5.4:
SELECT
oc.id,
oc.name,
oat.user_id,
p.first_name,
p.last_name
FROM
oauth_clients oc
LEFT JOIN oauth_access_tokens oat ON oc.id = oat.client_id
JOIN users u on u.id = oat.user_id
JOIN people p on p.id = u.person_id
WHERE oc.revoked = false AND oc.password_client = true
GROUP BY oc.id, oat.user_id
And getting this error barf: Argument 1 passed to Illuminate\Database\Connection::prepareBindings() must be of the type array, string given, called in /var/www/html/source/luniverse/vendor/laravel/framework/src/Illuminate/Database/Connection.php on line 648 and defined
This is my attempt at it (one of many):
$tokens = DB::select('oc.id','oc.name','oat.user_id','p.first_name','p.last_name')
->from('oauth_clients as oc')
->leftJoin('oauth_access_tokens as oat', 'oc.id', '=', 'oat.client_id')
->join('users as u', 'u.id', '=', 'oat.user_id')
->join('people as p', 'p.id', '=', 'u.person_id')
->where('oc.revoked', '=', 'false')
->where('oc.password_client', '=', 'true')
->groupBy('oc.id')
->groupBy('oat.user_id')
->get();
The database config is set to strict mode, but that doesn't exactly seem to explain that particular error. The raw query runs fine in a DB gui.

Change the groupby code like
$tokens = DB::select('oc.id','oc.name','oat.user_id','p.first_name','p.last_name')
->from('oauth_clients as oc')
->leftJoin('oauth_access_tokens as oat', 'oc.id', '=', 'oat.client_id')
->join('users as u', 'u.id', '=', 'oat.user_id')
->join('people as p', 'p.id', '=', 'u.person_id')
->where('oc.revoked', '=', 'false')
->where('oc.password_client', '=', 'true')
->groupBy('oc.id','oat.user_id')
->get();

DB::select() executes a query, you have to use DB::table():
DB::table('oauth_clients as oc')
->select('oc.id','oc.name','oat.user_id','p.first_name','p.last_name')

If using a query builder as to what in the form of its laravel?

I have a query sql like the following may be a bit complex, I am a bit of trouble to convert into a for framework laravel. Please help for everything with framework laravel query results. My problem here is, I do not know how to create a sub select query to laravel framework. Thanks guys.
SELECT
lin_users.status_employee_id,
lin_users.id,
lin_users.username,
lin_users.created,
lin_users.modified,
lin_employee_attributes.unit_code,
lin_employee_attributes.position_code,
lin_employee_attributes.begin_date,
lin_employee_attributes.end_date,
contactnumber.contact_id as phone_number,
contactmobile.contact_id as cell_number,
contactemail.contact_id as email
FROM lin_users
INNER JOIN lin_status_employees
ON lin_users.status_employee_id = lin_status_employees.id
INNER JOIN lin_people
ON lin_status_employees.person_id = lin_people.id
INNER JOIN lin_employee_attributes
ON lin_users.status_employee_id = lin_employee_attributes.status_employee_id
LEFT JOIN lin_contacts AS contactnumber
ON lin_people.id = contactnumber.person_id AND contactnumber.contact_type = 'Work Telephone'
LEFT JOIN lin_contacts AS contactmobile
ON lin_people.id = contactmobile.person_id AND contactmobile.contact_type = 'Mobile'
LEFT JOIN lin_contacts AS contactemail
ON lin_people.id = contactemail.person_id AND contactemail.contact_type = 'Email'
WHERE lin_employee_attributes.begin_date = '2016-11-07'
OR lin_employee_attributes.end_date = '2017-10-21'
GROUP BY lin_users.id,
lin_employee_attributes.unit_code,
lin_employee_attributes.position_code,
lin_employee_attributes.begin_date,
lin_employee_attributes.end_date, lin_people.id,
contactnumber.contact_id,
contactmobile.contact_id,
contactemail.contact_id;

Try this:
const TABLE = 'my_table_name';
return $this
->select(
self::TABLE . 'id as myidalias',
self::TABLE . 'username as myuseralias')
->addSelect(DB::raw(
"
(your custom select here) as mycustomresult
"
));
You can add as many addSelect as you want. Also when you have a lot of complex queries like this, a lot of times you have duplicated parts on them so I highly recommend using scopes it makes your code clean and reusable.
public function scopeLeftJoinCategory($query)
{
return $query
->leftJoin(Category::CONTENTS_CATEGORIES . ' AS cc', 'con.id', '=', 'cc.content_id')
->leftJoin(Category::TABLE . ' AS cat', 'cc.category_id', '=', 'cat.id');
}
Then you just use it like this: ->leftJoinCategory()

Using this work. Finally, with the above query can be solved with the concept query to query in laravel.
$users = $this->db->getTable('users')
->select('users.status_employee_id',
'users.id',
'users.username',
'users.email',
'users.created',
'users.modified',
'users.flag_delete',
'employee_attributes.unit_code',
'employee_attributes.position_code',
'employee_attributes.begin_date',
'employee_attributes.end_date',
'contactnumber.contact_id as phone_number',
'contactmobile.contact_id as cell_number',
'contactemail.contact_id as email'
)
->join('status_employees', 'users.status_employee_id', '=', 'status_employees.id')
->join('people', 'status_employees.person_id', '=', 'people.id')
->join('employee_attributes', 'users.status_employee_id', '=', 'employee_attributes.status_employee_id')
->leftJoin('contacts AS contactnumber', function($join)
{
$join->on('people.id', '=', 'contactnumber.person_id');
$join->on('contactnumber.contact_type','=', DB::raw("'Work Telephone'"));
})
->leftJoin('contacts AS contactmobile', function($join)
{
$join->on('people.id', '=', 'contactmobile.person_id');
$join->on('contactmobile.contact_type','=', DB::raw("'Mobile'"));
})
->leftJoin('contacts AS contactemail', function($join)
{
$join->on('people.id', '=', 'contactemail.person_id');
$join->on('contactemail.contact_type','=', DB::raw("'Email'"));
})
->where(function ($query) use ($begin_date, $end_date) {
$query->where('employee_attributes.begin_date', $begin_date)
->orWhere('employee_attributes.end_date', $end_date);
})
->groupby('users.status_employee_id',
'users.id',
'users.username',
'users.email',
'users.created',
'users.modified',
'users.flag_delete',
'employee_attributes.unit_code',
'employee_attributes.position_code',

Convert mysql query into Eloquent laravel query

I am trying to make the following query in laravel:
SELECT a.name AS subname, a.area_id, b.name, u. id, u.lawyer_id,u.active_search,
FROM subarea a
LEFT JOIN user_subarea u ON u.subarea_id = a.id
AND u.user_id = ?
LEFT JOIN branch b ON a.area_id = b.id
The idea is to obtain the subareas and see if the search is activated by the user.
The user_subarea table might have a record that matches the id of the subarea table where the active_search is equal to 0 or 1. If it doesn't exist I would like the query to return null.
While I was able to achieve this in raw SQL when I try the same with eloquent in Laravel I am not returning any value. I have done the following:
$query = DB::table('subarea')
->join('user_subarea', function($join)
{
$value = \Auth::user()->id;
$join->on( 'subarea.id', '=', 'user_subarea.subarea_id')->where('user_subarea.user_id', '=',$value);
})
->leftJoin('branch', 'subarea.area_id', '=', 'branch.id')
->select('branch.name', 'subarea.name as subarea', 'user_subarea.active_search_lawyer', 'user_subarea.id' )
->get();
Any help will be much appreciated.

I found by myself the answer it was just to add a lefjoin in the first join. It is not in the laravel docs but works too.
$query = DB::table('subarea')
->lefjoin('user_subarea', function($join)
{
$value = \Auth::user()->id;
$join->on( 'subarea.id', '=', 'user_subarea.subarea_id')->where('user_subarea.user_id', '=',$value);
})
->leftJoin('branch', 'subarea.area_id', '=', 'branch.id')
->select('branch.name', 'subarea.name as subarea', 'user_subarea.active_search_lawyer', 'user_subarea.id' )
->get();

Try this one, If you get a problem, please comment.
$value = \Auth::user()->id;
$query = DB::table('subarea')
->where('user_subarea.user_id', '=',$value)
->leftJoin('user_subarea', 'subarea.id', '=', 'user_subarea.subarea_id')
->leftJoin('branch', 'subarea.area_id', '=', 'branch.id')
->select('subarea.name AS subname','subarea.area_id', 'branch.name', 'user_subarea.id','user_subarea.lawyer_id','user_subarea.active_search')
->get();

Passing parameter bindings to Laravel query builder?

I currently have a SQL query which a fantastic stackoverflow member helped me with earlier today. At the moment it works absolutely fine and the way I want it to work.
The only problem is it's RAW SQL and I'd very much like to get this working with the Laravel Query Builder.
SORRY THIS IS AN EDIT - HERE IS THE ORIGINAL QUERY:
$addresses = DB::select(
DB::raw('
(SELECT
"Company" AS object_type_name,
companies.company_name AS object_name,
addresses.*
FROM
addresses
INNER JOIN
companies
ON
addresses.object_id = companies.id
WHERE
addresses.object_type = 2)
UNION ALL
(SELECT
"Job" AS object_type_name,
jobs.job_title AS object_name,
addresses.*
FROM
addresses
INNER JOIN
jobs
ON
addresses.object_id = jobs.id
WHERE
addresses.object_type = 4)
'));
Here is the code I have so far:
$bindings = array(
'soft_deleted' => 0,
'user' => 1,
'company' => 2,
'candidate' => 3,
'job' => 4,
);
$companies = DB::table('addresses')->select(
'addresses.*',
'companies.company_name as object_name'
)->where('addresses.soft_deleted', '=', 0)->join('companies', function($join) use ($bindings){
$join->on('addresses.object_id', '=', 'companies.id')
->where('addresses.object_type', '=', $bindings['company']);
});
$jobs = DB::table('addresses')->select(
'addresses.*',
'jobs.job_title as object_name'
)->join('jobs', function($join) use ($bindings){
$join->on('addresses.object_id', '=', 'jobs.id')
->where('addresses.object_type', '=', $bindings['job']);
});
$addresses = $companies->unionAll($jobs)->get();
With the code above I'm getting the following error:
SQLSTATE[HY093]: Invalid parameter number (SQL: (select addresses., companies.company_name as object_name from addresses inner join companies on addresses.object_id = companies.id and addresses.object_type = 2 where addresses.soft_deleted = 0) union all (select addresses., jobs.job_title as object_name from addresses inner join jobs on addresses.object_id = jobs.id and addresses.object_type = ?))
I've done hours worth of searching but I can't seem to find the answer to this little problem.

I managed to fix it. It was as simple as removing the ->where from within each join closure and chaining it to the join itself and not nesting it.
Before:
$companies = DB::table('addresses')->select(
'addresses.*',
'companies.company_name as object_name'
)->where('addresses.soft_deleted', '=', 0)->join('companies', function($join) use ($bindings){
$join->on('addresses.object_id', '=', 'companies.id')
->where('addresses.object_type', '=', $bindings['company']);
});
$jobs = DB::table('addresses')->select(
'addresses.*',
'jobs.job_title as object_name'
)->join('jobs', function($join) use ($bindings){
$join->on('addresses.object_id', '=', 'jobs.id')
->where('addresses.object_type', '=', $bindings['job']);
});
After:
$companies = DB::table('addresses')->select(
'addresses.*',
'companies.company_name as object_name'
)->where('addresses.soft_deleted', '=', 0)->join('companies', function($join){
$join->on('addresses.object_id', '=', 'companies.id');
})->where('addresses.object_type', '=', 2);
$jobs = DB::table('addresses')->select(
'addresses.*',
'jobs.job_title as object_name'
)->where('addresses.soft_deleted', '=', 0)->join('jobs', function($join){
$join->on('addresses.object_id', '=', 'jobs.id');
})->where('addresses.object_type', '=', 4);
$addresses = $companies->unionAll($jobs)->get();
Hope this helps someone.

Complicated Laravel Query leftjoin a made query

Right now I want to have the sum of Sueldo in a column grouped by idEmpleado of table recibo. Im not sure if I can put the DB::table inside the left join. if not how could I call that table in a query to make a join with the information of the empleado.
Here is what I have so far
$pagos = DB::table('empleado')
->leftJoin('empresa', 'empresa.idEmpresa', '=', 'empleado.emp_idEmpresa_FK')
->leftJoin('departamento', 'departamento.idDepartamento', '=', 'empleado.emp_idDeparameto_FK')
->leftJoin('tipoperiodo', 'tipoperiodo.idTipoPeriodo', '=', 'empleado.emp_idTipoPeriodo_FK')
->leftJoin(
DB::table('recibos')
->leftJoin('empleado', 'empleado.idEmpleado', '=', 'recibos.rec_idEmpleado_FK')
->select(DB::raw('idRecibos, rec_idEmpleado_FK, SUM(SueldoBase) as Restante'))
->groupBy('rec_idEmpleado_FK')
->get()
,'recibos', 'recibos.rec_idEmpleado_FK', '=', 'empleado.idEmpleado')
->select('idEmpleado', 'Nombre', 'Nombre_Depto', 'Nombre_Empresa', 'Puesto', 'SueldoBase', 'Restante')
->get();
I'm getting an error ErrorException with message :
Array to string conversion
I'm suppose its because I'm trying to make a leftjoin of a query im making there. Dunno Im knid of new to this. Any suggestions ?
With the help of the answer in the commnets I got to this Query,
DB::table('empleado')
->leftJoin('empresa', 'empresa.idEmpresa', '=', 'empleado.emp_idEmpresa_FK')
->leftJoin('departamento', 'departamento.idDepartamento', '=', 'empleado.emp_idDeparameto_FK')
->leftJoin('tipoperiodo', 'tipoperiodo.idTipoPeriodo', '=', 'empleado.emp_idTipoPeriodo_FK')
->leftjoin(
DB::raw('SELECT rec_idEmpleado_FK, SUM( SueldoBase ) AS Restante
FROM `recibos`
INNER JOIN empleado ON rec_idEmpleado_FK = idEmpleado
GROUP BY rec_idEmpleado_FK'),
function($join)
{
$join->on('idEmpleado', '=', 'rec_idEmpleado_FK');
})
->select('idEmpleado', 'Nombre', 'Nombre_Depto', 'Nombre_Empresa', 'Puesto', 'SueldoBase', 'Restante')
->get();
But still get the error:
check the manual that corresponds to your MySQL server version for the right syntax to use near
SELECT rec_idEmpleado_FK, SUM( SueldoBase ) AS Restante
FROM `recibos`
Any ideas why?

Ok I finally got the answer. I forgot to put the name to the inner query here is my answer. I hope it helps. I based my answer in the link that Chelsea gave me. Thanks
$pagos = DB::table('empleado')
->leftJoin('empresa', 'empresa.idEmpresa', '=', 'empleado.emp_idEmpresa_FK')
->leftJoin('departamento', 'departamento.idDepartamento', '=', 'empleado.emp_idDeparameto_FK')
->leftJoin('tipoperiodo', 'tipoperiodo.idTipoPeriodo', '=', 'empleado.emp_idTipoPeriodo_FK')
->leftjoin(
DB::raw('(SELECT rec_idEmpleado_FK, SUM( SueldoBase ) AS Restante
FROM `recibos`
INNER JOIN empleado ON rec_idEmpleado_FK = idEmpleado
GROUP BY rec_idEmpleado_FK) AS recibos1'),
function($join)
{
$join->on('idEmpleado', '=', 'rec_idEmpleado_FK');
})
->select('idEmpleado', 'Nombre', 'Nombre_Depto', 'Nombre_Empresa', 'Puesto', 'SueldoBase', 'Restante')
->get();
