Hi I have 3 tables in DB. Here is my query:
$nav = PageNav::with([
'page' => function($query) {
$query->where('status', 1)
->where(function($query) {
$query->whereNull('publish_up')
->whereNull('publish_down');
})
->orWhere(function ($query) {
$query->where('publish_up', '<', date('Y-m-d H:i:s'))
->where('publish_down', '>', date('Y-m-d H:i:s'));
});
},
'langs' => function ($query) use ($lang) {$query->where('language_code', '=', $lang);},
])
->get();
It generates this queries:
When I loop $nav there are still pages with status = 0. I really don't understand why? Any suggestions?
As with any SQL query or Eloquent query, OR completely separates the conditions, so as soon as you have an orWhere in eloquent, it will match anything that matches before the OR or after the OR.
You can resolve this by using a nested where, or parentheses in SQL, to properly encapsulate the conditions.
$query->where('status', 1)
->whereNested(function($q1) {
$q1->where(function($query) {
$query->whereNull('publish_up')
->whereNull('publish_down');
})
->orWhere(function ($query) {
$query->where('publish_up', '<', date('Y-m-d H:i:s'))
->where('publish_down', '>', date('Y-m-d H:i:s'));
});
});
Ok I found solution. Needed to wrap condition to whereHas
$nav = PageNav::whereHas('page', function ($query) {
$query->where('status', 1)
->whereNested(function($q1) {
$q1->where(function($query) {
$query->whereNull('publish_up')
->whereNull('publish_down');
})
->orWhere(function ($query) {
$query->where('publish_up', '<', date('Y-m-d H:i:s'))
->where('publish_down', '>', date('Y-m-d H:i:s'));
});
});
})
->with([
'page',
'langs' => function ($query) use ($lang) {
$query->where('language_code', '=', $lang);
}
])
->get();

I have this query:
$result = PortingItem::whereHas('porting', function ($query) {
$query->whereIn('status', [
Porting::STATUS_REQUESTED,
Porting::STATUS_ACCEPTED,
Porting::STATUS_DELAYED,
]);
})->where(function ($query) use ($numbers) {
$query->whereBetween('phone_number_start', [$numbers[0], $numbers[1]])
->orWhereBetween('phone_number_end', [$numbers[0], $numbers[1]]);
})->orWhere([
['phone_number_start', '<=', $numbers[0]],
['phone_number_end', '>=', $numbers[1]],
])->get();
The PortingItem model still returns the query result while the porting relation is empty. I don't understand why this happens.
This is my Porting model relation
public function items()
{
return $this->hasMany(PortingItem::class);
}
This is my PortingItem model relation:
public function porting()
{
return $this->belongsTo(Porting::class);
}
You should always group orWhere calls in order to avoid unexpected behavior when global scopes are applied.
$result = PortingItem::whereHas('porting', function ($query) {
$query->whereIn('status', [
Porting::STATUS_REQUESTED,
Porting::STATUS_ACCEPTED,
Porting::STATUS_DELAYED,
]);
})->where(function ($query) use ($numbers) {
$query->where(function ($query) use ($numbers) {
$query->whereBetween('phone_number_start', [$numbers[0], $numbers[1]])
->orWhereBetween('phone_number_end', [$numbers[0], $numbers[1]]);
})->orWhere(function ($query) use ($numbers) {
$query->where('phone_number_start', '<=', $numbers[0])
->where('phone_number_end', '>=', $numbers[1]);
});
})->get();

How can I select on whereHas() some columns in relation.
My current query looks like as it follows
Location::select(['title'])
->withCount(['job' => function($q) {
return $q->where('language_id', 1)->whereNull('deleted_at');
}])->whereHas('country', function ($q) {
return $q->where('id', '=', 80);
})->get();
and I tried
Location::select(['title', 'id as value'])->withCount(['job' => function($q) {
return $q->where('language_id', 1)->whereNull('deleted_at');
}])->whereHas('country', function ($q) {
return $q->select('title', 'iso3')->where('id', '=', 80);
})->get();
but nothing is getting returned on country relation. How do I refactor this query to get it work?
whereHas() doesn't eager load the relation, only filters results based on it. To eager load, use with().
Location::with('country:id,title,iso3')
->select(['title', 'id as value', 'country_id'])
->withCount(['job' => function($q) {
$q->where('language_id', 1)->whereNull('deleted_at');
}])
->whereHas('country', function ($q) {
$q->where('id', '=', 80);
})->get();
According to the Laravel documentation, an 'or' condition can be grouped by passing a Closure as the first argument to the orWhere method:
$users = DB::table('users')
->where('votes', '>', 100)
->orWhere(function($query) {
$query->where('name', 'Abigail')
->where('votes', '>', 50);
})
->get();
What I wanted is use a variable inside the query, which will look like:
$q = $request->get('query');
$users = DB::table('users')
->where('votes', '>', 100)
->orWhere(function($query) {
$query->where('name', $q)
->where('votes', '>', 50);
})
->get();
I tried to pass it as a second argument, like:
$q = $request->get('query');
$users = DB::table('users')
->where('votes', '>', 100)
->orWhere($q, function($query, $q) {
$query->where('name', $q)
->where('votes', '>', 50);
})
->get();
But it is not working, any help?
you need to use use() function to pass data into closer
ref link In PHP, what is a closure and why does it use the "use" identifier?
$q = $request->get('query');
$users = DB::table('users')
->where('votes', '>', 100)
->orWhere(function ($query) use($q) { // use function to pass data inside
$query->where('name', $q)
->where('votes', '>', 50);
})
->get();
I have a query 3 tables are joined together, I want to order the results in Descending order from created_at in messages table, please help. Thank you.
controller:
return new AllChats(Chat::latest('created_at')->whereHas('messages')->with(['messages.users', 'users' =>
function ($query) {
$query->where('id', '!=', Auth::id());
}])->whereHas('users', function ($query) {
$query->where('id', '=', Auth::id());
})->get());
Display the results in desc order but from messages.created_at??
You need to just add the ->orderBy on your created at field in your query.
return new AllChats(Chat::latest('created_at')->whereHas('messages')->with(['messages.users',
'users' => function ($query) {
$query->where('id', '!=', Auth::id());
}])
->orderBy('created_at', 'desc')
->whereHas('users', function ($query) {
$query->where('id', '=', Auth::id());
})->get());
Reference: https://laravel.com/docs/5.7/eloquent
use like this
return new AllChats(Chat::latest('created_at')>>whereHas('messages',function($q){
$q->orderBy('created_at', 'desc');
})->with(['messages.users', 'users' =>
function ($query) {
$query->where('id', '!=', Auth::id());
}])->whereHas('users', function ($query) {
$query->where('id', '=', Auth::id());
})->get());
You can use a modified withCount():
$chats = Chat::withCount(['messages as latest_message' => function($query) {
$query->select(DB::raw('max(created_at)'));
}])
->orderByDesc('latest_message')
[...]
->get();
I have my query working perfectly in mySQL, however am struggling to use the advanced wheres inside the laravel query builder.
Can anyone assist in converting this at all?
So far I have:
LARAVEL
$start_request = '2014-12-18 09:00';
$end_request = '2014-12-18 10:00';
$events= DB::table('events')
->where('hotel_id', 4)
->orWhere(function($query)
{
$query->where($start_request, '<=', 'start_time')
->where($end_request, '>', 'start_time');
})
->orWhere(function($query)
{
$query->where($start_request, '>=', 'start_time')
->where($end_request, '<', 'end_time');
})
->get();
mySQL
SELECT id, title, description, start_time, end_time FROM events where hotel_id = 4 and (('2014-12-18 09:00' <= start_time and '2014-12-18 10:00' > start_time)
or ('2014-12-18 09:00' >= start_time and '2014-12-18 10:00' < end_time));
Can you try this?
$start_request = '2014-12-18 09:00';
$end_request = '2014-12-18 10:00';
$events= DB::table('events')
->where('hotel_id', 4)
->where(function($query) use($start_request, $end_request) {
$query->where(function($subquery) use($start_request, $end_request){
$subquery->where('start_time', '>=', $start_request)
->where('start_time', '<', $end_request);
});
$query->orWhere(function($subquery1) use($start_request, $end_request) {
$subquery1->where('start_time', '<=', $start_request)
->where('end_time', '>', $end_request);
});
})
->get();
Something like this should do the job:
$start_request = '2014-12-18 09:00';
$end_request = '2014-12-18 10:00';
$events = DB::table('events')
->where('hotel_id', 4)
->where(function ($q) use ($start_request, $end_request) {
$q->where(function ($query) use ($start_request, $end_request) {
$query->where($start_request, '<=', 'start_time')
->where($end_request, '>', 'start_time');
})
->orWhere(function ($query) use ($start_request, $end_request) {
$query->where($start_request, '>=', 'start_time')
->where($end_request, '<', 'end_time');
});
})
->select('id', 'title', 'description', 'start_time', 'end_time')
->get();
