Laravel查询与联合和计数

Question

I have the queries:

$dateToday = date('Y-m-d',strtotime(Carbon::today()));

$countTodayMatchOccurrences = DB::table('occurrences')->select('date')->whereDate('date', '=', $dateToday);
$countTodayMatch = DB::table('matches')->select('date')->whereDate('date', '=', $dateToday)->union($countTodayMatchOccurrences)->count();

And I have the table, look like this: Table matches :

And table occurrences :

I don't know why, but my query does not work correctly. My query returns 2 , but should return 4 .

Answer 1

You can use Laravel Debugbar to view the actual queries that are run and verify that they are what you want. I would also run the whole thing as one query.

I would also normalize the database a bit more. Add a model URL and a corresponding urls table with id, match_id, url, accepted.

Answer 2

It looks like you are forgetting a

->get() for your first query.

$dateToday = date('Y-m-d',strtotime(Carbon::today()));

$countTodayMatchOccurrences = DB::table('occurrences')->select('date')->whereDate('date', '=', $dateToday)->get();
$countTodayMatch = DB::table('matches')->select('date')->whereDate('date', '=', $dateToday)->union($countTodayMatchOccurrences)->count();
