如何从 laravel 控制器中的 5 个表编写 mysql 连接子查询

Question

我有一个如下所示的 MySQL 查询，我想在 laravel 控制器中使用它，

我知道如何在laravel中使用join，但是当我们在join语句中有另一个子查询时，我不知道如何写，

SELECT barangs.id, barangs.kode_barang, barangs.nama_barang, 
IFNULL(a.QTY_IN,0) AS masuk, IFNULL(b.QTY_OUT,0) AS keluar, 
IFNULL(c.PO_RETUR_QTY,0) AS po_retur, IFNULL(d.CUS_RETUR_QTY,0) AS cus_retur, 
barangs.stok AS stok_akhir, barangs.harga_beli
FROM barangs 

LEFT JOIN (
SELECT barang_masuk_detail.id_barang, barang_masuk.tgl_masuk, SUM(barang_masuk_detail.qty_terima) AS QTY_IN
FROM barang_masuk
LEFT JOIN barang_masuk_detail ON barang_masuk.id = barang_masuk_detail.id_brg_masuk
/* WHERE barang_masuk.tgl_masuk BETWEEN "2015-08-01" AND "2015-08-31" */
GROUP BY barang_masuk_detail.id_barang ASC
)AS a ON a.id_barang = barangs.id

LEFT JOIN (
SELECT barang_keluar_detail.id_barang, barang_keluar.tgl_kirim, SUM(barang_keluar_detail.qty_dikirim) AS QTY_OUT
FROM barang_keluar
LEFT JOIN barang_keluar_detail ON barang_keluar.id = barang_keluar_detail.id_brg_keluar
/* WHERE barang_keluar.tgl_kirim BETWEEN "2015-08-01" AND "2015-08-31"*/
GROUP BY barang_keluar_detail.id_barang ASC
)AS b ON b.id_barang = barangs.id

/*join retur try */
LEFT JOIN (
SELECT retur_beli_detail.barang_id, retur_beli.tgl_retur, SUM(retur_beli_detail.retur_qty) AS PO_RETUR_QTY
FROM retur_beli
LEFT JOIN retur_beli_detail ON retur_beli.id = retur_beli_detail.retur_id
/* WHERE retur_beli.tgl_retur BETWEEN "2015-08-01" AND "2015-08-31"*/
GROUP BY retur_beli_detail.barang_id ASC
)AS c ON c.barang_id = barangs.id

/*join retur dari customer */
LEFT JOIN (
SELECT retur_kirim_detail.barang_id, retur_kirim.tgl_retur, SUM(retur_kirim_detail.retur_qty) AS CUS_RETUR_QTY
FROM retur_kirim
LEFT JOIN retur_kirim_detail ON retur_kirim.id = retur_kirim_detail.retur_id
/* WHERE retur_kirim.tgl_retur BETWEEN "2015-08-01" AND "2015-08-31"*/
GROUP BY retur_kirim_detail.barang_id ASC
)AS d ON d.barang_id = barangs.id

如果我运行在 sqlyog 中它按预期工作，但不确定如何用 laravel 语法编写它，

哦，如果可能的话，根据用户发送的请求，使用 laravel 中的 whereBetween 过滤它，我需要在哪里放置语法？

比如 whereBetween([ $request->startDate, $request->endDate ]);

Answer 1

使用以下语法执行查询的简单方法：-

DB::select("select * from table JOIN ...");

这将为您提供过滤数据的集合。

已编辑代码

要使用 whereBetween() Laravel 需要编写 MySQL 如下查询的查询

$startDate = $request->startDate;
$endDate = $request->endDate;

DB::select("
    select * from table JOIN ... 
    where fieldName BETWEEN '$startDate' AND '$endDate'
");

要添加更多条件，我们需要编写 Plain MySQL 查询。
