Php 将大型MySQL查询转换为使用Laravel的DB

我有一个非常大的查询，如下所示：

SELECT *

FROM cont_contracting
LEFT OUTER JOIN contacts_cont_contracting_1_c l1_1 ON cont_contracting.id=l1_1.contacts_cont_contracting_1cont_contracting_idb AND l1_1.deleted=0

LEFT OUTER JOIN contacts l1 ON l1.id=l1_1.contacts_cont_contracting_1contacts_ida AND l1.deleted=0
LEFT OUTER JOIN contacts_contacts_12_c l2_1 ON l1.id=l2_1.contacts_contacts_12contacts_ida AND l2_1.deleted=0

LEFT OUTER JOIN contacts l2 ON l2.id=l2_1.contacts_contacts_12contacts_idb AND l2.deleted=0
LEFT OUTER JOIN contacts_contacts_1_c l3_1 ON l1.id=l3_1.contacts_contacts_1contacts_ida AND l3_1.deleted=0

LEFT OUTER JOIN contacts l3 ON l3.id=l3_1.contacts_contacts_1contacts_idb AND l3.deleted=0
LEFT OUTER JOIN contacts_contacts_2_c l4_1 ON l1.id=l4_1.contacts_contacts_2contacts_ida AND l4_1.deleted=0

LEFT OUTER JOIN contacts l4 ON l4.id=l4_1.contacts_contacts_2contacts_idb AND l4.deleted=0
LEFT OUTER JOIN contacts_contacts_4_c l5_1 ON l1.id=l5_1.contacts_contacts_4contacts_ida AND l5_1.deleted=0

LEFT OUTER JOIN contacts l5 ON l5.id=l5_1.contacts_contacts_4contacts_idb AND l5.deleted=0
LEFT OUTER JOIN contacts_contacts_5_c l6_1 ON l1.id=l6_1.contacts_contacts_5contacts_ida AND l6_1.deleted=0

LEFT OUTER JOIN contacts l6 ON l6.id=l6_1.contacts_contacts_5contacts_idb AND l6.deleted=0
LEFT JOIN  huge__insurance_carriers_cont_contracting_1_c l7_1 ON cont_contracting.id=l7_1.huge__insurance_carriers_cont_contracting_1cont_contracting_idb AND l7_1.deleted=0

LEFT JOIN  huge__insurance_carriers l7 ON l7.id=l7_1.huge__insucae9arriers_ida AND l7.deleted=0
LEFT JOIN cont_contracting_cstm cont_contracting_cstm ON cont_contracting.id = cont_contracting_cstm.id_c

WHERE (((l1.id='b8a00721-40f1-7801-b4b9-50ce152ce2ec'
) OR (l2.id='b8a00721-40f1-7801-b4b9-50ce152ce2ec'
) OR (l3.id='b8a00721-40f1-7801-b4b9-50ce152ce2ec'
) OR (l4.id='b8a00721-40f1-7801-b4b9-50ce152ce2ec'
) OR (l5.id='b8a00721-40f1-7801-b4b9-50ce152ce2ec'
) OR (l6.id='b8a00721-40f1-7801-b4b9-50ce152ce2ec'
)))

我一直在尝试使用Laravel的查询生成器来转换它，这就是我想到的，但它仍然没有得到数据：

        $appts = DB::table('cont_contracting')
                    ->leftJoin('contacts_cont_contracting_1_c as l1_1', 'cont_contracting.id', '=', 'l1_1.contacts_cont_contracting_1cont_contracting_idb')
                    ->leftJoin('contacts as l1', 'l1.id', '=', 'l1_1.contacts_cont_contracting_1contacts_ida')
                    ->leftJoin('contacts_contacts_12_c as l2_1', 'l1.id', '=', 'l2_1.contacts_contacts_12contacts_ida')
                    ->leftJoin('contacts as l2', 'l2.id', '=', 'l2_1.contacts_contacts_12contacts_idb')
                    ->leftJoin('contacts_contacts_1_c as l3_1', 'l1.id', '=', 'l3_1.contacts_contacts_1contacts_ida')
                    ->leftJoin('contacts as l3', 'l3.id', '=', 'l3_1.contacts_contacts_1contacts_idb')
                    ->leftJoin('contacts_contacts_2_c as l4_1', 'l1.id', '=', 'l4_1.contacts_contacts_2contacts_ida')
                    ->leftJoin('contacts as l4', 'l4.id', '=', 'l4_1.contacts_contacts_2contacts_idb')
                    ->leftJoin('contacts_contacts_4_c as l5_1', 'l1.id', '=', 'l5_1.contacts_contacts_4contacts_ida')
                    ->leftJoin('contacts as l5', 'l5.id', '=', 'l5_1.contacts_contacts_4contacts_idb')
                    ->leftJoin('contacts_contacts_5_c as l6_1', 'l1.id', '=', 'l6_1.contacts_contacts_5contacts_ida')
                    ->leftJoin('contacts as l6', 'l6.id', '=', 'l6_1.contacts_contacts_5contacts_idb')
                    ->leftJoin('huge__insurance_carriers_cont_contracting_1_c as l7_1', 'cont_contracting.id', '=', 'l7_1.huge__insurance_carriers_cont_contracting_1cont_contracting_idb')
                    ->leftJoin('huge__insurance_carriers as l7', 'l7.id', '=', 'l7_1.huge__insucae9arriers_ida')
                    ->leftJoin('cont_contracting_cstm as cont_contracting_cstm', 'cont_contracting.id', '=', 'cont_contracting_cstm.id_c')
                    ->where(function($query) {
                        $query->orWhere('l1.id', '=', Session::get('id'))
                              ->orWhere('l2.id', '=', Session::get('id'))
                              ->orWhere('l3.id', '=', Session::get('id'))
                              ->orWhere('l4.id', '=', Session::get('id'))
                              ->orWhere('l5.id', '=', Session::get('id'))
                              ->orWhere('l6.id', '=', Session::get('id'));
                    })
                    ->get();

我所做的哪些错误导致Laravel查询无法正确获取记录

我上下检查了很多次文档，都没有发现问题

谢谢

您的where子句将简化为字段1、字段2、…、字段n中的where$值。这不是问题的解决方案，但它是减少查询中重复次数的一种方法。另外，如果您的表已经正常化，您可以将这些重复的联系人连接减少为一个。@MarcB我使用的是一个旧数据库，我对该数据无能为力，因为它连接到一家公司的CRM数据库。您检查过它运行的查询吗？您可以以各种方式执行“原始”SQL查询，我没有尝试过任何一种方式！1使用“DB:：select”。另一个选项：。最后，获取PDO连接并自己运行：DB:：connection->getPdo。
