Laravel Query Builder raw query with two FROM statements - mysql

Question

my apologies if this question sounds a little boring for someone I really turn here because I have already tried to solve my problem in different ways and I have not been able to obtain good results.
I am trying to convert a MySQL query to Laravel Query Builder, I show you the query:
SELECT DAY(AAA.fecha_hora_entrada) as DAY, IFNULL(BBB.SALES, 0) SALES, IFNULL(BBB.NET, 0) NET
FROM (
SELECT fecha_hora_entrada
FROM (
SELECT MAKEDATE(YEAR(NOW()), 1) +
INTERVAL (MONTH(NOW()) - 1) MONTH +
INTERVAL daynum DAY fecha_hora_entrada
FROM (
SELECT t * 10 + u daynum
FROM (SELECT 0 t UNION SELECT 1 UNION SELECT 2 UNION SELECT 3) A,
(SELECT 0 u UNION SELECT 1 UNION SELECT 2 UNION SELECT 3 UNION SELECT 4 UNION SELECT 5 UNION SELECT 6 UNION SELECT 7 UNION SELECT 8 UNION SELECT 9) B
ORDER BY daynum
) AS AA
) AS AA
WHERE MONTH(fecha_hora_entrada) = MONTH(NOW())
) AS AAA
LEFT JOIN (SELECT (DATE(fecha_hora_entrada)) AS fecha_hora_entrada, (SUM(neto)) AS NET, (COUNT(neto)) AS SALES
FROM t_derivados
GROUP BY DATE(fecha_hora_entrada)) BBB
ON AAA.fecha_hora_entrada = BBB.fecha_hora_entrada;
What I have tried so far is the following. So far I have managed to pass part of the MySQL query to Query Builder
public function salesYear()
{
return DB::table(DB::table(DB::table(DB::table(DB::table(null, null)
->selectRaw('0 t UNION SELECT 2 UNION SELECT 3'),'A')
->orderBy('daynum')
->selectRaw('t * 10 + u daynum'), 'AA')
->selectRaw('MAKEDATE(YEAR(NOW()), 1) + INTERVAL (MONTH(NOW()) - 1) MONTH + INTERVAL daynum DAY fecha_hora_entrada'), 'AA')
->addSelect('fecha_hora_entrada')
->whereRaw('MONTH(fecha_hora_entrada) = MONTH(NOW())'), 'AAA')
->selectSub('DAY(AAA.fecha_hora_entrada)', 'DAY')
->selectSub('IFNULL(BBB.SALES, 0)', 'SALES')
->selectSub('IFNULL(BBB.NET, 0)', 'NET')
->leftJoinSub(DB::table('t_derivados')
->selectSub('DATE(fecha_hora_entrada)', 'fecha_hora_entrada')
->selectSub('SUM(neto)', 'NET')
->selectSub('COUNT(neto)', 'SALES')
->groupBy(DB::raw('DATE(fecha_hora_entrada)')), 'BBB', 'AAA.fecha_hora_entrada', 'BBB.fecha_hora_entrada')
->toSql();
}
I know it's a bit boring to read everything .. but let's focus on the next sub-sentence:
SELECT t * 10 + u daynum
FROM (SELECT 0 t UNION SELECT 1 UNION SELECT 2 UNION SELECT 3) A,
(SELECT 0 u UNION SELECT 1 UNION SELECT 2 UNION SELECT 3 UNION SELECT 4 UNION SELECT 5 UNION SELECT 6 UNION SELECT 7 UNION SELECT 8 UNION SELECT 9) B
ORDER BY daynum
...
The truth is I have not found a way to add the second FROM to Query Builder
SELECT 0 u UNION SELECT 1 UNION SELECT 2 UNION SELECT 3 UNION SELECT 4 UNION SELECT 5 UNION SELECT 6 UNION SELECT 7 UNION SELECT 8 UNION SELECT 9) B
...
Someone expert on the subject could help me please. Thank you very much in advance
