Copy link

db.Joins("Company", db.Where(&Company{Alive: true})).Find(&users)
的输出结果是 select ... from sometable Company

查了不少文章,chatgpt也试试了
有效果的就是 db.Joins("LEFT JOIN Company ON ...")
这个好呆
1、Company用字符串输入本身就很呆,不是应该用模型去解析表名吗?
2、ON里的字段不是应该用.Where()方法来拼吗?用字符串来写,还不如.Raw()呢!!!

如果希望使用gorm的join自动拼接,需要你的相关表结构体有关联关系

你也可以用gen来实现,我代码里面就直接这样干过去
