To sum multiple SQL queries in Laravel, you can use the DB facade along with the selectRaw method to perform the queries and then sum the results. Here's an example of how you can achieve this:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14
$total = DB::selectRaw('
    SELECT SUM(column_name) as total
    FROM table_name
    WHERE condition
')[0]->total;

// You can add more queries and sum the results
$total = $total + DB::selectRaw('
    SELECT SUM(column_name) as total
    FROM another_table
    WHERE another_condition
')[0]->total;

echo $total; // output the sum of the results


Make sure to replace the column_name with the actual column name that you want to sum, table_name with the name of the table, and condition with the condition you want to apply. You can add more queries and sum the results as needed.


Another way to sum the results of multiple SQL queries in Laravel is to use the DB::raw method within the select statement. Here's an example:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14
$total = DB::table('table_name')
    ->selectRaw('SUM(column_name) as total')
    ->where('condition')
    ->get()
    ->sum('total');

// You can add more queries and sum the results
$total = $total + DB::table('another_table')
    ->selectRaw('SUM(column_name) as total')
    ->where('another_condition')
    ->get()
    ->sum('total');

echo $total; // output the sum of the results


In this example, table_name, another_table, column_name, condition, and another_condition should be replaced with the actual table names, column names, and conditions of your queries.


These are two ways you can sum the results of multiple SQL queries in Laravel. Choose the method that works best for your needs and adapt it to fit your specific requirements.
