【中文标题】我雄辩的查询构建器实例返回空，而 sql 子句返回结果。会欣赏第二只眼睛

【英文标题】：My eloquent query builder instance is returning empty while the sql clause returns results. would appreciate a second eye

【问题描述】：

在将 sql 查询转换为查询生成器时，我被卡住了，因为查询返回一个空集，而我知道原始 SQL 子句将返回约 200 条记录。

使用 toSql() 和控制台测试进行故障排除。我猜我有一个奇怪的“在哪里”或“在”扔东西，但我似乎无法确定它。我提前感谢你所有的眼睛。谢谢。

现在是 php

                )->leftjoin('job_price_line as jpl', function ($join) 
                    $join->on('jph.job_price_hdr_uid', '=', 'jpl.job_price_hdr_uid')
                        ->whereRaw('CAST (im.inv_mast_uid as nvarchar(15)) = jpl.inv_mast_uid')
                        ->where('jpl.row_status_flag', '=', (int)704);//active flag
                )->leftjoin('inv_loc as il_b', function ($join) use ($mainWarehouse) 
                    $join->on('d.inv_mast_uid', '=', 'il_b.inv_mast_uid')
                        ->where('il_b.location_id', '=', (int)$mainWarehouse)
                        ->where('il_b.delete_flag', '=', "'N'");
                )->leftjoin('inv_loc as il_c', function ($join) use ($consignmentWarehouse)

                )->where('h.customer_id', '=', (int)$AccountGroup[0]->corp_address_id)

【问题讨论】：

请添加所有变量。

【参考方案1】：

我注意到的一件事是，您左连接表 item_commitment_detail，然后在 item_commitment_detail.inv_mast_uid 上内连接 inv_mast。

这有效地将（左）外部联接更改为内部联接。

如果 item_commitment_detail 必须是左连接，那么 inv_mast 也应该是左连接。

考虑到样式和可读性，您可以考虑先列出所有内连接，然后再列出外连接。这将立即显示出这种（不需要的）关系。

【参考方案2】：

好的，事实证明定价表（标题和行）不满意......为什么我不知道，但是，将两个连接与子查询一起移动似乎已经解决了这个问题。

$prices = DB::connection('p21')->table('job_price_line as jpl')
        ->select('item_id', 'uom', 'price')
        ->join('job_price_hdr as jph', function ($join) use ($job_no) 
            $join->on('jpl.job_price_hdr_uid', '=', 'jph.job_price_hdr_uid')
                ->whereRaw('jph.job_no = ' . $job_no[0]);
        )->join('inv_mast as im', 'jpl.inv_mast_uid', '=', 'im.inv_mast_uid')
        ->whereRaw('jpl.row_status_flag = 704')
        ->toSql();

然后

->join(DB::raw("(" . $prices . ") as p"), function ($join) 
            $join->on('im.item_id', '=', 'p.item_id');
