How can put a MYSQL sentence in laravel: - mysql

Question

SELECT Code_tank, temperature, salinity, PH, parameters.created_at as created_at FROM parameters WHERE id IN (SELECT MAX(id) FROM parameters group by code_Tank) ORDER BY code_tank ASC;
I have been trying to put this SQL sentence in laravel but could not, this is the code with that i was trying:
$testMonitor= DB::table('parameters')
->select('code_Tank', 'salinity', 'PH', 'temperature',
DB::raw('parameters.created_at AS created_at'))
->whereIn('id', DB::raw('SELECT MAX(id) FROM parameters group by code_Tank'))
->orderby('code_Tank', 'asc')->get();
And this is the error, I assumed that one of the parameters in WHEREIN must be an array but I can't think of any other way to accommodate the SQL statement in laravel, please if you could help me
TypeError: Argument 1 passed to Illuminate/Database/Query/Builder::cleanBindings() must be of the type array, object given, called in C:/laragon/www/SoftwareOzimandias/vendor/laravel/framework/src/Illuminate/Database/Query/Builder.php on line 907

Answer 1

DB::Raw() will return an object as the second parameter for whereIn, but whereIn want to take the parameter that is array.
You can use closure, check the where-clauses reference:
DB::table('parameters')->whereIn('id', function($query){
$query->select(DB::raw('MAX(id)'))
->from('parameters')
->groupBy('code_Tank');
})->orderby('code_Tank', 'asc')
->select('code_Tank', 'salinity', 'PH', 'temperature',
DB::raw('parameters.created_at AS created_at'))
->get();
