table not found while using db raw in repository in laravel - database

Question

I am using repository for querying day from date.
if i use only db raw then it works fine, but i don't like to use whole db::raw query in repository so i used db:raw where i needed.
when i used it, it shows error like table not found as table is found if that qyery is removed.
<?php
namespace App\Repositories\Api\Order;
use DB;
use Bosnadev\Repositories\Contracts\RepositoryInterface;
use Bosnadev\Repositories\Eloquent\Repository;
/**
* Class ArticleRepository
*
* #package app\Repository
*/
/**
* Created by PhpStorm.
* User: sabin
* Date: 5/10/16
* Time: 10:29 AM
*/
class OrderRepository extends Repository
{
/**
* #return string
*/
function model()
{
return 'App\Models\Order\Order';
}
function getAll($id)
{
return $this->makeModel()
->join('tbl_sales as sales', 'sales.id', '=', 'tbl_order.sales_id')
->select('sales.date', 'sales.delivery_date', 'sales.total_amount', DB::select(DB::raw("select day(tbl_sales.delivery_date) as day")))
->where('sales.client_id', '=', $id)
->groupBy('tbl_order.sales_id')
->get();
}
}
Error:
SQLSTATE[42S02]: Base table or view not found: 1109 Unknown table 'tbl_sales' in field list (SQL: select day(tbl_sales.delivery_date) as day)
s same problem.
note: i have used sales.delivery_date too, but it show
I have tried putting table command too like:
function getAll($id)
{
return $this->makeModel()
->join('tbl_sales as sales', 'sales.id', '=', 'tbl_order.sales_id')
->select('sales.date', 'sales.delivery_date', 'sales.total_amount', DB::select(DB::raw("select month(tbl_sales.delivery_date) as month from tbl_sales")))
->where('sales.client_id', '=', $id)
->groupBy('tbl_order.sales_id')
->get();
}
but also it is showing this problem.

You create an alias to the tbl_sales as sales here:
->join('tbl_sales as sales', 'sales.id', '=', 'tbl_order.sales_id')
So I am guessing you should refer to it as sales elsewhere, can you try this to see if it helps:
return $this->makeModel()
->join('tbl_sales as sales', 'sales.id', '=', 'tbl_order.sales_id')
->select(
'sales.date',
'sales.delivery_date',
'sales.total_amount',
// sales here not tbl_sales
DB::select(DB::raw("select day(sales.delivery_date) as day"))
)
->where('sales.client_id', '=', $id)
->groupBy('tbl_order.sales_id')
->get();
If it doesn't work then my approach would be to get the raw sql and get the query working via sql firstly.
To get the raw sql eloquent is generating you could try the following on your query then dd()ing it:
$q = $this->makeModel()
->join('tbl_sales as sales', 'sales.id', '=', 'tbl_order.sales_id')
->select(
'sales.date',
'sales.delivery_date',
'sales.total_amount',
// sales here not tbl_sales
DB::select(DB::raw("select day(sales.delivery_date) as day"))
)
->where('sales.client_id', '=', $id)
->groupBy('tbl_order.sales_id')
->toSql();
dd($q);
or:
DB::enableQueryLog();
dd(DB::getQueryLog());
or install https://github.com/barryvdh/laravel-debugbar
Once you've got the raw sql of the query you can play around with it in your favourite editor and run it directly on the database until you get the desired results then make the required modifications in elqouent to reflect the correct code.
Hope that helps!
