Mysql query to laravel eloquent or query builder nested select - php

Question

I got the following code that gonna return the sum of score if tgl is '2023-01-01' and then that return value will be selected again to not show any null that the query find
SELECT *
FROM (
SELECT `kodeSales`,
`departemenId`,
`tgl`,
(SELECT SUM(CASE WHEN tgl IN ('2023-01-01') THEN score END)) AS '1'
FROM `history_penjualan`
WHERE `tgl` BETWEEN '2023-01-01' AND '2023-01-30'
`departemenId` = '28'
GROUP BY `tgl`
) AS temp
WHERE '1' IS NOT NULL
How do I do this in laravel eloquent or query builder ?

Answer 1

Try this way,
I tried this and it works. but in here you can change the ->having() statement as havingRaw("'1' IS NOT NULL") or I provided code also works.
$sum_of_score = DB::table('history_penjualan')
->select('kodeSales', 'departemenId', 'tgl', DB::raw("SUM(CASE WHEN tgl = '2023-01-01' THEN score END) AS '1'"))
->whereBetween('tgl', ['2023-01-01', '2023-01-30'])
->where('departemenId', '=', 28)
->groupBy('tgl')
->having('1', '!=', null)
->get();
If you want to learn about Laravel queries refer the document.
https://laravel.com/docs/9.x/queries
or if you need query in dynamic try this way,
$query = DB::table('history_penjualan')
->select(DB::raw('kodeSales, departemenId, tgl, SUM(CASE WHEN tgl = "2023-01-01" THEN score END) as "1"'))
->whereBetween('tgl', ['2023-01-01', '2023-01-30'])
->where('departemenId', '=', '28')
->groupBy('tgl');
$final_data = $query->having('1', '<>', null)->get();
If this is not your expected answer please leave a comment, I'll give another way to do this :)
