I've made an API with the Yii2 framework.
But I don't know how to use the OR condition in my statement.
For example:
I want to get all cars with brand BMW or DODGE.
I've tried the following:
$query = Car::getCar($lang)
->where(['or', ['m.brand' => 'BMW'], ['m.brand' => 'DODGE']])
->all();
But this doesn't work.
I only get it to work with one value for m.brand.
So:
$query = Car::getCar($lang)
->where(['m.brand' => 'BMW'])
->all();
Works just fine.
Tried to put in a few other ways, but I don't get this to work.
Does anyone know what I'm doing wrong?
EDIT
The getCar method returns something like:
(new Query())->select(['a.auto_id'])->from('auto_new a')
EDIT 2
Got it to work with:
$query->andWhere(['or', ['m.brand' => 'BMW'], ['m.brand' => 'DODGE']])
You can actually simplify it a lot by using an array with the values you need:
$query = Car::getCar($lang)
->where(['m.brand' => ['BMW', 'DODGE']])
->all();
This will execute with something like WHERE m.brand IN ('BMW', 'DODGE') which returns the result you are looking for.
If I understand you well, you could use something like this:
Model::find()
->orWhere(['brand' => 'brand1'])
->orWhere(['id' => 'brand2'])
->all();
where() can take an array to create sql along the lines of
SELECT * FROM car WHERE brand in ('brand1', 'brand2');
using this construct you can generate an array of brands you wish to return then use the following ActiveQuery.
$brands = ['BMW', 'DODGE'];
$query = Car::find()->where(['brand' => $brands])->all();

I am new to laravel. I have an array. It looks like this.
$state=[
1 => "Utah"
2 => "California"
3 => "Nevada"
6 => "Arizona"
]
I am trying to query the table in a database called a county. I want to display all the county that falls in those states which are in the array.
I write a code like this
foreach($state as $st) {
$data= DB::table('state')->Select(County)->where('name','=', $st)->get();
dd($data);
}
This is the code that I wrote. It does only return for the first state then after that, it gets stopped can someone help me. Any kind of help is appreciated.
It stops because dd() is dump and DIE. So it is like you would call:
dump($data);
die();
Try something like:
$query= DB::table('state');
foreach($state as $st) {
$query->orWhere('name','=', $st);
}
$data = $query->get();
It will make one DB call instead of X calls and returns a collection of records with which you can work.
You can try:
DB::table('country')->whereIn('name', array_values($state))->get();
You have to give categories to filter and next join eachother
App\YourModel::select('what you want')->join('category','your_models.id','=','category.your_model_id')->get();
On my models I try to write a php model that will get me a associative array from a database. But I don't quite know how to approach this.
So after I execute this SQL query:
SELECT balance_events.weight,balance_events.added_date,
balance_entries.mid FROM balance_events, balance_entries
WHERE balance_entries.added_date BETWEEN '2016-08-02' AND '2016-08-03'
AND balance_entries.ptid =12
AND balance_entries.beid = balance_events.id
I will get this table:
And from that table I want to extract a asociative array that it will look like this:
count = ['13'=>1, '6'=>4, '16'=>3, '4'=>3]
where 'mid'=>number of how many times that mid can be found in the table.
ex. mid '13'=>1 cause you can found it only once.
I think that I will have to use SQL COUNT function, but how I can aggregate all of this in a PHP model in codeigniter? I know how to configure controller and view, but I don't know how to actually do the actual php model that will get me the desired array.
Try this query may help you ,
$result = $this->db->select('balance_events.weight,balance_events.added_date,COUNT(balance_entries.mid) as mid_count')
->from('balance_events, balance_entries')
->where('balance_entries.added_date BETWEEN "2016-08-02" AND "2016-08-03" ')
->where('balance_entries.ptid','12')
->where('balance_entries.beid','balance_events.id')
->group_by('balance_entries.mid')
->get();
return $result->result_array();
I'm not sure how you would create this in SQL but since you tagged php, I wrote a function that would do just this.
<?php
$query = array(array("mid"=>13), array("mid"=>2), array("mid"=>13), array("mid" =>6), array("mid" => 13), array("mid" => 6));
function createMidArray($queryResult){
$returnArray = array();
foreach ($queryResult as $qr){
$returnArray[$qr['mid']]++;
}
return $returnArray;
}
print_r(createMidArray($query));
?>
The output of this was Array ( [13] => 3 [2] => 1 [6] => 2 ) which matches up to my inputted $query (which is a 2D array). I'm expecting the output of your query is stored in a similar array, but with more data and keys
I essentially want to search the database using an array of barcodes. Here is my query if I only have one barcode:
$q = new CDbCriteria(array(
'condition' => '"barcode" = :barcode',
'params' => array(':barcode' => $this->barcode),
));
I am trying to modify this query so that I query an array of barcodes. It would be a fairly standard array, something like ['Barcode1','Barcode2', 'Barcode3'].
How can I modify this query I have to instead return the results for Barcode1 OR Barcode2 OR Barcode3?
You need to add an inCondition
http://www.yiiframework.com/doc/api/1.1/CDbCriteria#addInCondition-detail
something like this
$q = new CDbCriteria();
$q->addInCondition("barcode",array("value1","value2"...),"AND");
I was wondering how to perform something like this:
Table::update(array('position'=>'position+1'));
As far as I know, laravel 4 handles 'position+1' as a string, thus is becomes 0.
I want to perform something like
UPDATE table SET position = position + 1
Can I do that using eloquent?
EDIT: nevermind, doh.."DB::table('users')->increment('votes');"
Simply make use of the increment method:
DB::table('users')->increment('position');
The same is valid for decrement:
DB::table('users')->decrement('rank');
You may even set the second parameter to the amount you want to add/subtract:
DB::table('users')->increment('posts', 5);
DB::table('users')->decrement('likes', 3);
Also, if you need to update other columns along with it, you pass it as the third parameter:
DB::table('users')->increment('range', 3, array(
'name' => 'Raphael',
'rank' => 10
));
And the same goes for Eloquent models, as well:
$firstUser = User::find(1);
$firstUser->increment('height', 0.1, array(
'active' => false
));
you can also do with DB::raw method like this:
DB::table('tablename')->where(your condition)->update(['position' => DB::raw('position+1')]);
you can also do other operations with this like
DB::table('tablename')->where(your condition)->update(['position' => DB::raw('position * 2')]);
This worked fine for me
\Models\User::where("id", $userId)->increment("points");
simply you can use the DB::raw method like this：
Table::update(DB::raw('position=position+1'));
I have a very complex setup on my tables and achieving this via any of the find() methods is not an option for me, since I would need to fix relationships between my tables and I don't have the time right now, so I'm looking for a simple fix here.
All I want to achieve is run a query like this:
SELECT MAX( id ) as max FROM MyTable WHERE another_field_id = $another_field_id
Then, I need to assign that single id to a variable for later use.
The way I have it now it returns something like [{{max: 16}}], I'm aware I may be able to do some PHP on this result set to get the single value I need, but I was hoping there was already a way to do this on CakePHP.
Assuming you have a model for your table and your are using CakePHP 2.x, do:
$result = $this->MyTable->field('id', array('1=1'), 'id DESC');
This will return a single value.
see Model::field()
This example is directly from the CakePHP documentation. it seems you can use the find method of a model to get count
$total = $this->Article->find('count');
$pending = $this->Article->find('count', array(
'conditions' => array('Article.status' => 'pending')
));
$authors = $this->Article->User->find('count');
$publishedAuthors = $this->Article->find('count', array(
'fields' => 'DISTINCT Article.user_id',
'conditions' => array('Article.status !=' => 'pending')
));
