I am trying to do an eloquent query where it joins on a table where column a = x OR column b = x; and I cannot get it to work. So I am hoping that someone can help.
Here is my query:
$candidates = HrCandidate::where('people_id', '<>', 'NULL')
->with('contact')
->join(
'people',
->where('id','people_id')
->orWhere('alternate_id','people_id')
)
->get();
I am trying to join with the people table but where people_id = 1 or the alternate_id column. So I am hoping someone can help with this.
To get started, pass a Closure as the second argument into the join method. The Closure will receive a JoinClause object which allows you to specify constraints on the join clause:
$candidates = HrCandidate::join('people', function ($join) {
$join
->on('people.id', '=', 'candidates.people_id')
->orOn('people.alternate_id', '=', 'candidates.people_id');
})
->where('people_id', '<>', 'NULL')
->get();

How do you know the other code to get this query in laravel using eloquent?
$variable_value= DB::select(
'SELECT
sv.VARIABLE_NAME as sv_variable_name, sv.TYPE as sv_type, sv.ADDRESS as sv_address, sv.VALUE as sv_value,
ms.VARIABLE_NAME as ms_variable_name, ms.TYPE as ms_type, ms.ADDRESS as ms_address, ms.VALUE as ms_value
FROM MASTER_VARIABLES ms
JOIN SLAVE_VARIABLES sv ON ms.SLV_ADDRESS=sv.ID_VARIABLE'
);
Thank you for your help, guys!
It's all in the documentation. Give it a read?
# Selects
Specifying A Select Clause
You may not always want to select all columns from a database table. Using the select method, you can specify a custom select clause for the query:
$users = DB::table('users')->select('name', 'email as user_email')->get();
# Joins
Inner Join Clause
The query builder may also be used to write join statements. To perform a basic "inner join", you may use the join method on a query builder instance. The first argument passed to the join method is the name of the table you need to join to, while the remaining arguments specify the column constraints for the join. You can even join to multiple tables in a single query:
$users = DB::table('users')
->join('contacts', 'users.id', '=', 'contacts.user_id')
->join('orders', 'users.id', '=', 'orders.user_id')
->select('users.*', 'contacts.phone', 'orders.price')
->get();
$query = DB::table('MASTER_VARIABLES as ms')
->select(
'sv.VARIABLE_NAME as sv_variable_name',
'sv.TYPE as sv_type',
'sv.ADDRESS as sv_address',
'sv.VALUE as sv_value',
'ms.VARIABLE_NAME as ms_variable_name',
'ms.TYPE as ms_type',
'ms.ADDRESS as ms_address',
'ms.VALUE as ms_value'
)
->join('SLAVE_VARIABLES as sv', 'ms.SLV_ADDRESS', '=', 'sv.ID_VARIABLE')
->get();
I am trying to turn my raw sql into laravel query builder and I encounter difficulty on how to join multiple tables using with many attributes match.
In this case, I want to join the table jr_h and jr_d with three attributes match (book,p_seq and staff_code) rather than one (book).
Raw sql:
$sql = "select from_time,to_time,t.staff_code,s.name_t as staff_name,t.book,t.p_code,t.p_seq,p.hrs1,s.img_file,
t.hrs_work,p.sharing_cnt as hrs_work, t.hrs_ot as hrs_ot from jr_d as t
inner join jr_h as p on(t.book=p.book and t.p_seq=p.p_seq and t.staff_code=p.staff_code)
inner join astaff as s on(t.staff_code=s.staff_code) ";
Laravel query builder:
$jr_d = DB::table('jr_d')
->join('jr_h', 'jr_d.book', '=', 'jr_h.book')
->join('astaff', 'jr_d.staff_code', '=', 'astaff.staff_code')
->select('jr_h.*','jr_d.*','astaff.*','astaff.name_t as staff_name')
->where('jr_d.ref_group','=','E')
->get();
and also want to know if there is a way to make the query faster since it has a lot of data in the tables.
Laravel joins with multiple conditions:
$results = DB::table('jr_d')
->select('jr_h.*','jr_d.*','astaff.*','astaff.name_t as staff_name')
->join('jr_h', 'jr_d.book', '=', 'jr_h.book')
->join('jr_h as p', function($query){
$query->on('t.book','=', p.book');
$query->on('t.p_seq','=', 'p.p_seq');
$query->on('t.staff_code', '=', 'p.staff_code');
})
->where('jr_d.ref_group','=','E')
->get();
`
Try this:
// ...
->join('jr_h p', function($join) {
$join->on('t.book', '=', 'p.book');
$join->on('t.p_seq', '=', 'p.p_seq');
// ... more conditions
});
Try this.
$jr_d = DB::table('jr_d')
->join('jr_h', 'jr_d.book', '=', 'jr_h.book')
->join('astaff', 'jr_d.staff_code', '=', 'astaff.staff_code')
->select('*','astaff.name_t as staff_name')
->where('jr_d.ref_group','=','E')
->get();
I am try
ing to get something like this
select * from `users`
inner join `settings`
on `users`.`id` = `settings`.`user_id`
and NOW() NOT BETWEEN quit_hour_start AND quit_hour_end
where `notification_key` != ''
and `device_type` = 'Android'
in eloquent. Does anyone try and get success to build this query in eloquent.
I know I can use \DB::select(DB::raw()); and get my result. But I want to use ie with Laravel eloquent method.
====== update comment for tried queries========
$androidUser = User::join('settings', function ($join) {
$join->on('users.id', '=', 'settings.user_id')
->where(DB::raw("'$currentTime' NOT BETWEEN quit_hour_start AND quit_hour_end"));
})
->where('notification_key', '!=', '')
->where('device_type' ,'=', 'Android')
->get();
$users = DB::table('users')
->whereNotBetween('votes', [1, 100]) // For one column
->whereRaw("? NOT BETWEEN quit_hour_start AND quit_hour_end", [$currentTime]) // Use whereRaw for two columns
->get();

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();
I have a question regarding join clauses in Eloquent, and whether you can join on a string value rather than a table column.
I have the code below querying a nested set joining parent/child records in a table 'destinations' via a table 'taxonomy'.
The second $join statement in the closure is the one causing an issue; Eloquent assumes this is a column, when I would actually just like to join on t1.parent_type = 'Destination' - ie, t1.parent_type should = a string value, Destination.
$result = DB::connection()
->table('destinations AS d1')
->select(array('d1.title AS level1', 'd2.title AS level2'))
->leftJoin('taxonomy AS t1', function($join) {
$join->on('t1.parent_id', '=', 'd1.id');
$join->on('t1.parent_type', '=', 'Destination');
})
->leftJoin('destinations AS d2', 'd2.id', '=', 't1.child_id')
->where('d1.slug', '=', $slug)
->get();
Is it possible to force Eloquent to do this? I've tried replacing 'Destination' with DB::raw('Destination') but this does not work either.
Thanking you kindly.
Another best way to achieve same is :
$result = DB::connection()
->table('destinations AS d1')
->select(array('d1.title AS level1', 'd2.title AS level2'))
->leftJoin('taxonomy AS t1', function($join) {
$join->on('t1.parent_id', '=', 'd1.id');
$join->where('t1.parent_type', '=', 'Destination');
})
->leftJoin('destinations AS d2', 'd2.id', '=', 't1.child_id')
->where('d1.slug', '=', $slug)
->get();
Replace your on with where
try using DB::raw("'Destination'")
