Laravel雄辩的查询并在OR条件下加入

Question

I am trying to do an eloquent query where it joins on a table where column a = x OR column b = x ; and I cannot get it to work. So I am hoping that someone can help.

Here is my query:

$candidates = HrCandidate::where('people_id', '<>', 'NULL')

  ->with('contact')

  ->join(

    'people',

    ->where('id','people_id')

    ->orWhere('alternate_id','people_id')

  )

  ->get();

I am trying to join with the people table but where people_id = 1 or the alternate_id column. So I am hoping someone can help with this.

Answer 1

To get started, pass a Closure as the second argument into the join method. The Closure will receive a JoinClause object which allows you to specify constraints on the join clause:

$candidates = HrCandidate::join('people', function ($join) {
        $join
            ->on('people.id', '=', 'candidates.people_id')
            ->orOn('people.alternate_id', '=', 'candidates.people_id');
    })
    ->where('people_id', '<>', 'NULL')
    ->get();
