Question

I want update a row with only where clause. I don't have row id, only i have 2 where clause. Is it possible? (with eloquent)

->where("x",1) ->where("y"=2)

Answer 1

When using Active Record, you should never perform an update directly in the database. First pull the record from the database, then update it:

Model::where(['x' => 1, 'y' => 2])->first()->update([...]);

If you instead do the update directly in the database, none of the ORM functionality will trigger (such as firing events or touching parents).
