How to combine four queries in laravel?

To combine four queries in Laravel, you can use the union() method to merge the results of multiple queries into a single result set. Here is an example of how you can combine four queries in Laravel:

1
2
3
4
5
6

$query1 = DB::table('table1')->select('column1', 'column2');
$query2 = DB::table('table2')->select('column3', 'column4');
$query3 = DB::table('table3')->select('column5', 'column6');
$query4 = DB::table('table4')->select('column7', 'column8');

$results = $query1->union($query2)->union($query3)->union($query4)->get();

In this example, we are selecting different columns from four different tables and using the union() method to combine the results of all four queries into a single result set. The get() method is then called to retrieve the final result set.
