To join multiple tables using max() in Laravel, you can use the DB facade along with the join() method to specify the tables you want to join. Then, use the select() method to select the columns you want, and finally use the max() method to retrieve the maximum value from a specific column.


Here's an example of how you can achieve this:

1
2
3
4
5
6
7
8
9
use IlluminateSupportFacadesDB;

$results = DB::table('table1')
    ->join('table2', 'table1.id', '=', 'table2.table1_id')
    ->join('table3', 'table2.id', '=', 'table3.table2_id')
    ->select('table1.column1', 'table2.column2', 'table3.column3')
    ->max('table3.column3');

dd($results);


In this example, we are joining three tables (table1, table2, table3) and selecting columns from each table. We then use the max() method to retrieve the maximum value from table3.column3.


Make sure to replace table1, table2, table3, column1, column2, column3 with your actual table and column names.
