Laravel ORM怎么用where case end？

Posted 2023-05-06

SELECT
c.`id`, c.`nickname`, cp.`id`
FROM
grshop.grs_customer AS c
LEFT JOIN
grs_customer_partner AS cp ON cp.`customer_id` = c.`recommend_customer_id`
WHERE
1 = CASE
WHEN c.`recommend_customer_id` = 0 THEN 0
WHEN
c.`recommend_customer_id` != 0
AND cp.`id` > 0
AND cp.`type` = 0
AND cp.`status` = 1
AND c.`created_at` > cp.`updated_at`
THEN
1
ELSE 2
END
GROUP BY c.`id`
ORDER BY c.`id` DESC;

参考技术A $query->whereRaw('LENGTH(code)=12');

laravel ORM 模型关联 with () 用法

关联时想对关联表数据筛选时：
MySQL查询:

SELECT *  FROM A
LEFT JOIN B
ON A.B_id = B.id AND B.condition = $condition

ORM模型查询使用with():

Model::with([‘table_name‘ => function ($query) use ($condition) {
            $query->where( "condition", $condition)
                        }])->get();)
