我只是好奇我们是否可以使用typeorm的findOne方法提供投影仪？我正在使用postgres数据库。
我需要的只是提供的电子邮件的表格中的ID。我得到的是用户的所有详细信息。
repository.findOne({email: 'abc@abc.com'})
这给了我所有细节。但是我只想提取该特定用户的ID
我们可以将投影仪传递给上述查询吗？例如
repository.findOne({email: 'email'},{id:1})
答案 0 :(得分：0)
是的，有可能。您需要将选项传递给import UserNotifications

函数，以便您的代码如下所示：
findOneOR
async getOne(email: string): Partial<RepositoryEntity> {
const foundRow = repository.findOne({
where: {
email: email
},
select: 'id'
});
return foundRow;
}
