Find two column in laravel which have equal values via Eloquent?

Question

I am working on a project where I have a table market which has a buyer_id column and a seller_id column. When a seller puts something on the market, the seller_id and buyer_id

Answer 1

Option 1: ->whereRaw('column1 = column2')

Option 2: When on sale buyer_id == null != seller_id, ->where('buyer_id', '=', null)

Answer 2

You need to use whereRaw to do it:

$market_records = Market::where('seller_id', '!=', Auth::user()->id)
                         ->whereRaw('seller_id = buyer_id')->get();

Anyone looking for this solution keep in mind since Laravel 5.2 it's possible to use whereColumn method instead, so above code in Laravel 5.2 and up could look like this:

$market_records = Market::where('seller_id', '!=', Auth::user()->id)
                         ->whereColumn('seller_id', 'buyer_id')->get();

You can find details in this commit

Answer 3

In recent Laravel versions you can use whereColumn (docs):

$same = Market::whereColumn('seller_id', 'buyer_id')->get();
