update `access_tokens` as at3 set at3.`expires` = 1393995576
where
`access_token_expires` > 1393995576
and at3.`id` in (select * from (

where `rt`.`refresh_token` = 's2kF5Ev6NXncnTPwVz99ksgsCGXfwPIDzXJMZJqz') as t)
I am trying above query in laravel 4 using query builder. But not able to find how to write this. I have written upto this:
DB::table("access_tokens as at3")
->whereIn('id', function($query) use ($authParams)
{
$query->select('at2.id')
->from('refresh_tokens as rt')
->leftJoin("access_tokens as at", "at.id", "=", "rt.session_access_token_id")
->join("access_tokens as at2", "at2.session_id", "=", "at.session_id")
->where('rt.refresh_token', '=', $authParams['refresh_token']);
})
//->delete();
->where('at3.access_token_expires', '>', time())
->update(array('at3.access_token_expires' => time()));
If you just need the query to work, you can use this syntax:
$affected_rows = DB::update( DB::raw("UPDATE users set username = 'wadus' WHERE username = :somevariable"), array('somevariable' => $someVariable));
It works and it's safe.

I need a following code to convert to Laravel query can any one help me with these.
SELECT id, `leave_name`, `total_leave_days`, leave_id, leave_taken_days FROM `leaves` AS t1 INNER JOIN ( SELECT leave_id, SUM(`leave_taken_days`) AS leave_taken_days FROM `leave_applications` WHERE user_id = 2 AND statuses_id = 2 GROUP BY leave_id ) AS t2 ON t1.id = t2.leave_id
I even tried but the output is not showing atall.
$user_leaves = DB::table('leaves')
->select('id', 'leave_name', 'total_leave_days', 'leave_id', 'leave_taken_days')
->join('leave_application', 'leave_application.leave_id', '=', 'leave.id')
->select('leave_application.leave_id', DB::raw("SUM(leave_taken_days) as leave_application.leave_taken_days"))
->where('user_id','=', 2)
->where('statuses_id','=', 2)
->get();
How can I solve this issue?
UPDATE
Relations between two models.
Leave Model
public function leave_application()
{
return $this->belongsTo(LeaveApplication::class, 'id' , 'leave_id');
}
Leave Application Model
public function leave()
{
return $this->belongsTo(Leave::class, 'leave_id', 'id');
}
Try this :
$user_leaves = Leave::select('leaves.id', 'leaves.leave_name', 'leaves.total_leave_days', 'leave_applications.leave_id', DB::raw('SUM(leave_applications.leave_taken_days) as leave_taken_days'))
->with('leave_application')
->whereHas('leave_application', function($q) {
$q->where('user_id', 2)
->where('statuses_id', 2);
})
->groupBy('leaves.id')
->get();
On this topic I would like to give my recommendations for some tools to help you out in the future.
SQL Statement to Laravel Eloquent to convert SQL to Laravel query builder. This does a decent job at low level queries. It also saves time when converting old code.
The other tool I use to view the query that is being run is Clock Work
I keep this open in a tab and monitor slow nasty queries or, also gives me perspective on how the query builder is writing SQL. If you have not use this extension I highly recommend getting and using it.
Actually I found my answer,
$user_leaves = DB::table('leaves as t1')
->select('t1.id', 't1.leave_name', 't1.total_leave_days', 't2.leave_id', 't2.leave_taken_days')
->join(DB::raw('(SELECT leave_id, SUM(leave_taken_days) AS leave_taken_days FROM leave_applications WHERE user_id = ' . $user_id . ' AND statuses_id = 2 GROUP BY leave_id) AS t2'), function ($join) {
$join->on('t1.id', '=', 't2.leave_id');
})
->get();
You can use DB:select("your query", params) and put your query and params (as an array (optional)
As below sample:
$result = DB:select("
SELECT id, `leave_name`, `total_leave_days`, leave_id, leave_taken_days
FROM `leaves` AS t1
INNER JOIN (
SELECT leave_id, SUM(`leave_taken_days`) AS leave_taken_days
FROM `leave_applications`
WHERE user_id = 2
AND statuses_id = 2
GROUP BY leave_id
) AS t2 ON t1.id = t2.leave_id" , $params
);
return response()->json($result);
I am using laravel 8. I have this mysql command which I want to convert into laravel query builder style:
select allocation.*, leav_leave_types.leave_type_code
from (
select * from leav_employee_annual_leave_allocations
where leave_year_id = $year_id and employee_id = $user_id
) as allocation
left join leav_leave_types on (leav_leave_types.id = allocation.leave_type_id)
Actually I want to apply a where clause first and then perform a left join for better performance.
How can I convert it into query builder style?
The only thing from your query that is not currently in the documentation is using a subquery as the main table.
This can be done by passing either a Closure or a Builder instance to the table() or from() method.
DB::table(closure, alias)
DB::table(builder, alias)
DB::query()->from(closure, alias)
DB::query()->from(builder, alias)
Using a Closure:
DB::table(function ($sub) use ($user_id, $year_id) {
$sub->from('leav_employee_annual_leave_allocations')
->where('leave_year', $year_id)
->where('employee_id', $user_id);
}, 'allocation')
->select('allocation.*', 'leav_leave_types.leave_type_code')
->leftJoin('leav_leave_types', 'leav_leave_types.id', 'allocation.leave_type_id')
->get();
DB::query()
->select('allocation.*', 'leav_leave_types.leave_type_code')
->from(function ($sub) use ($user_id, $year_id) {
$sub->from('leav_employee_annual_leave_allocations')
->where('leave_year', $year_id)
->where('employee_id', $user_id);
}, 'allocation')
->leftJoin('leav_leave_types', 'leav_leave_types.id', 'allocation.leave_type_id')
->get();
Using a Builder instance
$sub = DB::table('leav_employee_annual_leave_allocations') // or DB::query()->from('leav_employee_annual_leave_allocations')
->where('leave_year', $year_id)
->where('employee_id', $user_id);
DB::table($sub, 'allocation')
->select('allocation.*', 'leav_leave_types.leave_type_code')
->leftJoin('leav_leave_types', 'leav_leave_types.id', 'allocation.leave_type_id')
->get();
// personally my favorite way. I find it very readable.
$sub = DB::table('leav_employee_annual_leave_allocations') // or DB::query()->from('leav_employee_annual_leave_allocations')
->where('leave_year', $year_id)
->where('employee_id', $user_id);
DB::query()
->select('allocation.*', 'leav_leave_types.leave_type_code')
->from($sub, 'allocation')
->leftJoin('leav_leave_types', 'leav_leave_types.id', 'allocation.leave_type_id')
->get();
The generated SQL looks like this
select "allocation".*, "leav_leave_types"."leave_type_code" from (
select * from "leav_employee_annual_leave_allocations"
where "leave_year" = ? and "employee_id" = ?
) as "allocation"
left join "leav_leave_types" on "leav_leave_types"."id" = "allocation"."leave_type_id"
If you want a parenthesis around your join condition to be generated, you should use one of the following notations instead.
leftJoin('leav_leave_types', ['leav_leave_types.id' => 'allocation.leave_type_id'])
leftJoin('leav_leave_types', function ($join) {
$join->on(['leav_leave_types.id' => 'allocation.leave_type_id']);
})
leftJoin('leav_leave_types', function ($join) {
// will generate a parenthesis if there's more than one condition
$join->on('leav_leave_types.id', 'allocation.leave_type_id')
->on(...) // and condition
->orOn(...); // or condition
})
Alternatively, you could turn the SQL around to
select *,
( SELECT leave_type_code
FROM leav_leave_types
WHERE id = allocation.leave_type_id
) AS leave_type_code
FROM leav_employee_annual_leave_allocations AS allocation
where leave_year_id = $year_id and employee_id = $user_id
(This might be more efficient.)
In either case leav_employee_annual_leave_allocations would benefit from INDEX(employee_id, leave_year_id).
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 need to create a select query in Laravel 5.1 which I will have no problems creating via regular SQL and I am wondering if you could help me to write it in Laravel.
I created this query that gets all Users that have a truck, trailer and delivery_date equals a particular date (comes from $week_array). It is working, but it is missing some components
$RS = $this->instance->user()
->with(['driver.delivery' => function($query) use ($week_array) {
$query->where('delivery_date', [Carbon\Carbon::parse($week_array['date'])->toDateTimeString()]);
}])
->with(['driver.trailer', 'driver.truck', 'driver.trailer.trailerType'])->get();
I need to exclude those drivers that have MAX delivery date which equals or greater than selected delivery date in the query above. This is the normal query that I need to plug-in to laravel.
In other words, I need to convert the following query (simplified) to Laravel:
SELECT
*
FROM
USERS
INNER JOIN
DRIVERS ON DRIVERS.user_id = USERS.id
INNER JOIN
DELIVERIES ON DELIVERIES.driver_id = DRIVERS.id
WHERE
1 = 1
AND DELIVERIES.driver_id NOT IN (SELECT
driver_id
FROM
DELIVERIES
GROUP BY driver_id
HAVING MAX(delivery_date) >= '2016-05-10')
You're looking for whereHas. Try:
$date = Carbon\Carbon::parse($week_array['date'])->toDateTimeString();
$RS = $this->instance->user()
->with(['driver.delivery' => function($query) use ($date) {
$query->where('delivery_date', [$date]);
}])
->with(['driver.trailer', 'driver.truck', 'driver.trailer.trailerType'])
->whereHas('driver.delivery', function($query) use ($date) {
return $query->where('delivery_date', '>', $date);
}, '=', 0)
->get();
Also try validating the query looks right by replacing ->get() with ->toSql() and using the dd helper function.
I'm getting some unexpected results when running an Eloquent join query. I get two different results from using the exact same query. One running with DB::raw(), the second with Eloquent.
In the Eloquent query, the Users that matches the
where squad_user.leave_time >= seasons.start_time
are missing and will not be included in the result set. The users that matches the
or squad_user.leave is null
will be included, however.
That's the only difference in the results from the two queries. The raw query actually produces the desired result set.
What really puzzles me is, if I check the query logs, both Laravel's and MySQL, I get the exact same query when running both the raw and Eloquent query.
Raw query (the actual query i get from the query log when running the Eloquent query)
return \DB::select(\DB::raw('
select users.*
from users
inner join squad_user on users.id = squad_user.user_id
inner join seasons on squad_user.squad_id = seasons.squad_id
where squad_user.join_time <= seasons.end_time
and (squad_user.leave_time >= seasons.start_time or squad_user.leave_time is null)
and seasons.id = :seasonId
'),
['seasonId' => 3]
);
Eloquent query
return User::join('squad_user', 'users.id', '=', 'squad_user.user_id')
->join('seasons', 'squad_user.squad_id', '=', 'seasons.squad_id')
->where('squad_user.join_time', '<=', 'seasons.end_time')
->where(function ($query)
{
$query->where('squad_user.leave_time', '>=', 'seasons.start_time')
->orWhereNull('squad_user.leave_time');
})
->where('seasons.id', 3)
->get(['users.*']);
Laravel's Eloquent query log
select `users`.*
from `users`
inner join `squad_user` on `users`.`id` = `squad_user`.`user_id`
inner join `seasons` on `squad_user`.`squad_id` = `seasons`.`squad_id`
where `squad_user`.`join_time` <= seasons.end_time
and (`squad_user`.`leave_time` >= seasons.start_time or `squad_user`.`leave_time` is null)
and `seasons`.`id` = 3
{"bindings":["seasons.end_time","seasons.start_time",3],"time":0.38,"name":"mysql"}
MySQL's general_log on the Eloquent query
select `users`.*
from `users`
inner join `squad_user` on `users`.`id` = `squad_user`.`user_id`
inner join `seasons` on `squad_user`.`squad_id` = `seasons`.`squad_id`
where `squad_user`.`join_time` <= ?
and (`squad_user`.`leave_time` >= ? or `squad_user`.`leave_time` is null)
and `seasons`.`id` = ?
MySQL's general_log on the Raw query
select users.*
from users
inner join squad_user on users.id = squad_user.user_id
inner join seasons on squad_user.squad_id = seasons.squad_id
where squad_user.join_time <= seasons.end_time
and (squad_user.leave_time >= seasons.start_time or squad_user.leave_time is null)
and seasons.id = ?
I would appreciate any pointers here, as I am very lost.
where binds 3rd param and treats it usually as a string, unless you tell it not to by using raw statement. DB::raw or whereRaw will work for you:
return User::join('squad_user', 'users.id', '=', 'squad_user.user_id')
->join('seasons', 'squad_user.squad_id', '=', 'seasons.squad_id')
->where('squad_user.join_time', '<=', DB::raw('seasons.end_time'))
->where(function ($query)
{
$query->where('squad_user.leave_time', '>=', DB::raw('seasons.start_time'))
->orWhereNull('squad_user.leave_time');
})
->where('seasons.id', 3)
->get(['users.*']);
Since Laravel Verion 5.2 you can also use whereColumn to verify that two columns are equal (or pass a comparison operator to the method):
->whereColumn('squad_user.join_time', '<=', 'seasons.end_time')
