I want get field on msph_pl from ms_prod_harga
this is my model promo
is this correct ?
$this->db->select('*');
$this->db->from('md_promo');
$this->db->join('ms_promo','mspr_no = mdpr_mspd_no','left');
$this->db->join('ms_produk','mspd_no = mspr_no','left');
$this->db->join('ms_prod_harga', 'mspr_no = msph_no','left');
$this->db->where('mdpr_no',$mspr_no);
If your tables looks like this:
(table) md_promo
(value) mspr_no
(table) ms_produk
(value) mspd_no
(table) ms_prod_harga
(value) msph_no
And if you need to join result on msph_pl (value) from ms_prod_harga (table), then this code should work:
$this->db->select('*');
$this->db->from('md_promo');
$this->db->join('ms_prod_harga', 'md_promo.mspr_no = ms_prod_harga.msph_no', 'left');
$this->db->join('ms_produk', 'md_promo.mspr_no = ms_produk.mspd_no', 'left');
$query = $this->db->get();
echo "<pre>" . var_export($query->result_array(), true) . "</pre>"; // display the result_array in elegant form
Hope that helps, though, it may be not what you really need..

In my case i need to use collections together. But also i need that model too. I decided to merge eloquents. Like this:
$products = Product::orderBy('created_at', 'desc')->get();
$sliders = Slider::orderBy('order', 'asc')->get();
$news = News::orderBy('order', 'asc')->get();
$collection = new ModelCollection();
$result = $collection->merge($products)->merge($news)->merge($sliders)->sortByDesc('created_at');
dd($result);
$products has 4 data, $slider also has 4 data, $news has 3 data.
But i am allways get 4 data by sorting created_at. Why i can't get 11 data from the collection?
https://laravel.com/docs/5.6/collections#method-merge
in this case there is no limit or rules.
in the interest of brevity i am trying to make an array with my selected models. If its a collection it keeps model. If its just an array also i need to add the model name for each data collections.
array(
Products > product1,product2,product3,product4
News > news1, news2, news3
Slider > slider1, slider2, slider3
)
If you want all collections in one array you can do by this,
$products = Product::orderBy('created_at', 'desc')->get();
$sliders = Slider::orderBy('order', 'asc')->get();
$news = News::orderBy('order', 'asc')->get();
$result = array();
$result['products'] = $products;
$result['sliders'] = $sliders;
$result['news'] = $news;
This will create collection $result like you want,
array(
products > product1,product2,product3,product4
news > news1, news2, news3
sliders > slider1, slider2, slider3
)
Hope this will help you. Comment if any doubts.
So this code is a combination of 3 table joined, now i want to filter the query where only the request that a user can have is his/her own request and not from other user.. the problem is in where clause i have duplicated.
$this->db->order_by('loanrequest.ApplicationNo', 'DESC');
$query = $this->db->get('loanrequest','loanapplication','user');
$this->db->join('loanapplication','loanrequest.ApplicationNo = loanapplication.ApplicationNo');
$this->db->join('user', 'user.userId = loanapplication.userId');
$this->db->where('loanapplication.userId', $this->session->userdata('userId'));
$this->db->where('loanapplication.ApplicationNo', 'loanrequest.ApplicationNo');
return $query->result_array();
I can not get what you have done in your join query but Here is how I do join in my CodeIgniter model.
You don't need to put this in where condition:
$this->db->where('loanapplication.ApplicationNo', 'loanrequest.ApplicationNo');
Because you have already done that in the join query.
$query = $this->db->select('*')
->from('loanapplication')
->join('loanrequest', 'loanrequest.ApplicationNo = loanapplication.ApplicationNo', 'left')
->join('user', 'user.userId = loanapplication.userId', 'left')
->where_in('loanapplication.userId',$this->session->userdata('userId'))
->order_by('loanrequest.ApplicationNo', 'DESC')
->get();
return $query->result_array();
I will recommend you should use $this->db->last_query() because it gives you a better idea about your query.
$query = $this->db->select('*')
->from('loanapplication')
->join('loanrequest', 'loanrequest.ApplicationNo = loanapplication.ApplicationNo', 'left')
->join('user', 'user.userId = loanapplication.userId', 'left')
->where_in('loanapplication.userId',$this->session->userdata('userId'))
->order_by('loanrequest.ApplicationNo', 'DESC');
$result = $query->get();
echo $this->db->last_query();exit; //use this to print your query so that you can get the actual issue
if ($result->num_rows() > 0) {
return $result->result_array();
} else
return '';
$data is an array which contain user post data for fetch record from orders table
$data=array('customer_id'=>$this->input->post('custId'),'paided'=>2);
$this->db->select('*');
$this->db->from('orders');
$this->db->where($data);
$this->db->get();
$data = array(
'customer_id' => $this->input->post('custId')],
'paided' => 2
);
$this->db->select('*');
$this->db->from('orders');
$this->db->where($data);
$this->db->get();
try this :
public function function_name (){
$data = array (
'customer_id' => $this->input->post('custId'),
'paided' => 2
);
$this->db->select('*');
$this->db->from('ordere');
$this->db->where($data);
$query = $this->db->get();
return $query->result_array();
}
You have done all good just need to put result() if you get multiple row or row() if you get one row
$data=array('customer_id'=>$this->input->post('custId'),'paided'=>2);
$this->db->select('*');
$this->db->from('orders');
$this->db->where($data);
$result= $this->db->get()->result(); //added result()
print_r($result);
as simple use
$custId = $_post['custId'];
$query = $this->db->query("SELECT * FROM orders WHERE customer_id= '$custId' AND paided='2'");
$result = $query->result_array();
return $result;//result will be array
This is the plus of using framework, you don't need to write that much of code,
$where = array('customer_id' => $this->input->post('custId'),'paided'=>2)
$result = $this->db->get_where('orders', $where);
and for fetching them, use $result->row() for single record retrieval.
If you want all records, use $result->result()
Here is documentation link, if you want to learn more.
What You should need to be Correct And Why
$data=array('customer_id'=>$this->input->post('custId'),'paided'=>2);
$this->db->select('*'); // by defaul select all so no need to pass *
$this->db->from('orders');
$this->db->where($data);
$this->db->get(); // this will not return data this is just return object
So Your Code Should be
$data=array('customer_id'=>$this->input->post('custId'),'paided'=>2);
$this->db->select(); // by defaul select all so no need to pass *
$this->db->from('orders');
$this->db->where($data);
$query = $this->db->get();
$data = $query->result_array();
// or You can
$data= $this->db->get()->result_array();
here result_array() return pure array where you can also use result()
this will return array of object
I'd like to know the position of a user based on its creation date. How do I do that using Eloquent?
I'd like to be able to do something like this:
User::getRowNumber($user_obj);
I suppose you want MySQL solution, so you can do this:
DB::statement(DB::raw('set #row:=0'));
User::selectRaw('*, #row:=#row+1 as row')->get();
// returns all users with ordinal 'row'
So you could implement something like this:
public function scopeWithRowNumber($query, $column = 'created_at', $order = 'asc')
{
DB::statement(DB::raw('set #row=0'));
$sub = static::selectRaw('*, #row:=#row+1 as row')
->orderBy($column, $order)->toSql();
$query->remember(1)->from(DB::raw("({$sub}) as sub"));
}
public function getRowNumber($column = 'created_at', $order = 'asc')
{
$order = ($order == 'asc') ? 'asc' : 'desc';
$key = "userRow.{$this->id}.{$column}.{$order}";
if (Cache::get($key)) return Cache::get($key);
$row = $this->withRowNumber($column, $order)
->where($column, '<=',$this->$column)
->whereId($this->id)->pluck('row');
Cache::put($key, $row);
return $row;
}
This needs to select all the rows from the table till the one you are looking for is found, then selects only that particular row number.
It will let you do this:
$user = User::find(15);
$user->getRowNumber(); // as default ordered by created_at ascending
$user->getRowNumber('username'); // check order for another column
$user->getRowNumber('updated_at', 'desc'); // different combination of column and order
// and utilizing the scope:
User::withRowNumber()->take(20)->get(); // returns collection with additional property 'row' for each user
As this scope requires raw statement setting #row to 0 everytime, we use caching for 1 minute to avoid unnecessary queries.
$query = \DB::table(\DB::raw('Products, (SELECT #row := 0) r'));
$query = $query->select(
\DB::raw('#row := #row + 1 AS SrNo'),
'ProductID',
'ProductName',
'Description',
\DB::raw('IFNULL(ProductImage,"") AS ProductImage')
);
// where clauses
if(...){
$query = $query->where('ProductID', ...));
}
// orderby clauses
// ...
// $query = $query->orderBy('..','DESC');
// count clause
$TotalRecordCount = $query->count();
$results = $query
->take(...)
->skip(...)
->get();
I believe you could use Raw Expresssions to achieve this:
$users = DB::table('users')
->select(DB::raw('ROW_NUMBER() OVER(ORDER BY ID DESC) AS Row, status'))
->where('status', '<>', 1)
->groupBy('status')
->get();
However, looking trough the source code looks like you could achieve the same when using SQLServer and offset. The sources indicates that if you something like the following:
$users = DB::table('users')->skip(10)->take(5)->get();
The generated SQL query will include the row_number over statement.
[For Postgres]
In your model
public function scopeWithRowNumber($query, $column = 'id', $order = 'asc'){
$sub = static::selectRaw('*, row_number() OVER () as row_number')
->orderBy($column, $order)
->toSql();
$query->from(DB::raw("({$sub}) as sub"));
}
In your controller
$user = User::withRowNumber()->get();
Can someone tell me how to write this properly?
function get_tech() {
$this->db->select('u.id
,u.first_name
,us.id
,us.group_id');
$this->db->from('users u');
$this->db->join('users_groups us','us.id = u.id','left');
$records = $this->db->where('us.group_id', '3');
$data=array();
foreach($records->result() as $row)
{
$data[$row->id] = $row->first_name;
}
return ($data);
}
I'm trying to populate a drop down menu using an array, but i need to only grab users that are part of users_group/group_id = 3
therefore in my very limited knowledge I'm needing:
select X from Users LEFT JOIN users_groups WHERE group_ID = 3
You need to call $this->db->get() in order to actually run your query.
function get_tech() {
$this->db->select('u.id
,u.first_name
,us.id
,us.group_id');
$this->db->from('users u');
$this->db->join('users_groups us','us.id = u.id','left');
$this->db->where('us.group_id', '3');
$records = $this->db->get();
$data = array();
foreach($records->result() as $row){
$data[$row->id] = $row->first_name;
}
return $data;
}
