Laravel - Union + Paginate at the same time?

Question

Brief:

I am trying to union 2 tables recipes and posts then add ->paginate(5) to the queries.

But

Answer 1

For those who may still look for the answer, I have tried union and paginate together and got right result under laravel 5.7.20. This will be better than merging collections then paginate which will not work on big amount of data.

Some demo code (in my case, I will deal with multiple databases with same table name):

$dbs=["db_name1","db_name2"]; 
$query=DB::table("$dbs[0].table_name");
for($i=1;$iunion($query);
}
$query=$query->orderBy('id','desc')->paginate(50);

I haven't tried on other higher version of laravel. But at least it could work now!

More information

My previous version of laravel is 5.7.9 which will report the Cardinality violation error. So the laravel team solved this issue in some version of 5.7.x.
