# LARAVEL-Builder 这是一个可以提升`Laravel ORM`关联关系查询性能的扩展包,

环境

  • PHP >= 7
  • laravel >= 5.5

安装

composer require eugenes/laravel-builder

简介

Laravel的关联关系查询whereHas在日常开发中给我们带来了极大的便利,但是在主表数据量比较多的时候会有比较严重的性能问题,主要是因为whereHas用了where exists (select * ...) 这种方式去查询关联数据。

通过这个扩展包提供的whereHasIn,whereHasJoin方法

方法

whereHasIn

App(CompanyStaffModel::class)->whereHasIn('section', function ($query) {
    $query->where('id', 1);
})->first();
SELECT *
FROM `lk_company_staff`
WHERE `lk_company_staff`.`id` IN (SELECT `lk_company_staff_section_relation`.`userid`
                                  FROM `lk_company_staff_section_relation`
                                  WHERE `lk_company_staff`.`id` = `lk_company_staff_section_relation`.`userid`
                                    AND `id` = 1) LIMIT 1

whereHasJoin

App(CompanyStaffModel::class)->yjselect('*')->whereHasJoin('section', function ($query) {
         $query->yjwhere('id', 1);
})->first();
select `lk_company_staff`.*
from `lk_company_staff`
         left join `lk_company_staff_section_relation`
                   on `lk_company_staff_section_relation`.`userid` = `lk_company_staff`.`id`
where ((`lk_company_staff_section_relation`.`id` = 1)) limit 1

yjwhere

App(CompanyStaffModel::class)->yjwhere('id', 1)->first();
select *
from `lk_company_staff`
where `lk_company_staff`.`id` = 1 limit 1

yjselect

App(CompanyStaffModel::class)->yjselect('id')->first();
select `lk_company_staff`.`id`
from `lk_company_staff` limit 1
