To perform a sum operation on the results of multiple subqueries in Laravel, you can use the DB
facade along with the selectRaw
method to construct a SQL query that calculates the sum of the subquery results.
Here's an example of how you can achieve this:
1 2 3 4 5 6 7 8 9 |
use IlluminateSupportFacadesDB; $results = DB::table(DB::raw('(SELECT SUM(column1) as sum1 FROM table1) AS subquery1')) ->selectRaw('subquery1.sum1') ->leftJoin(DB::raw('(SELECT SUM(column2) as sum2 FROM table2) AS subquery2'), 'subquery1.sum1', '=', 'subquery2.sum2') ->selectRaw('subquery2.sum2 as total_sum') ->get(); dd($results); |
In this example, we have two subqueries that calculate the sum of column1
from table1
and column2
from table2
. We then join these two subqueries and retrieve the total sum of both subqueries.
You can customize the subqueries and columns according to your specific requirements.
