I strongly recommend to read Laravel documentation to fully understand basic Laravel concepts before writing any code (for example by convention model name should be Deal instead of deals and table name should be deals instead of tbl_deal, similar for primary key - it should be simple id instead of deal_id). we almost require left join everywhere in project because of related table. you can easily use left join in laravel 6 and laravel 7 version. >leftJoin('tbl_merchant','tbl_rchant_id','=','table_rchant_id')->get() Īnd now to display 1st merchant text you can use: $deal = $deals->first() If you are new in laravel and you don't know how to write left join in laravel application, then i will help you how to make left join in laravel application. The first argument passed to the join method is the name of the table you need to join to, while the remaining arguments specify the column constraints for the join. To perform a basic 'inner join', you may use the join method on a query builder instance. Now, demonstrates laravel eloquent join with the following examples. The query builder may also be used to add join clauses to your queries. productCategory Product::where ( 'id', productId) ->leftJoin ( 'category', 'product.category', '', 'category.id' ) ->select ( 'product.id', 'category. In case you want to use simple join instead of relationship in this case, you can use: $deals = deals::selectRaw('tbl_deal.*, tbl_rchant_url_text') Laravel JOIN eloquent returns all rows from both table, if there are matches in the both table. Solution Let’s improve this code example by combining both requests into a single query. First is using the Query Builder DB class and join method of eloquent. In the above syntax we have used 3 examples to show all possibilities to use join function in laravel eloquent. However to use this you need to create also Merchant model and using this method no join will be used. Laravel join accepts multiple parameters to the function and first parameter as table name and rest are columns constraints. Return $this->belongsTo(Merchant::class, merchant_id) Īnd now you will be able to get all deals with merchant using $deals = deals::with('merchant')->get() įor example to display the first one use: $deal = $deals->first() Accessors, mutators, and attribute casting allow you to transform Eloquent attribute values when you retrieve or set them on model instances. Firstly we target the user based on the userid, exactly the same query as the first one. The following function (called relationship): public function merchant() Using Joins in Laravel Eloquent Queries For Better Performance 1. Consider the sample code below, which use the Product and Category table to return the category name.
