javascript - Prisma 客户端从表中选择所有行

Question

如何使用 prisma 从表格中选择所有内容？ (从应用程序中选择 *)

const applications = prisma.application.findMany({
        // Returns all user fields
        include: {
            posts: {
                select: {
                    age: true,
                    about_section: true,
                    user_id: true
                },
            },
        },
    })
    console.log(applications.age)

这是我的模式的样子:

model application {
  application_id Int     @id @default(autoincrement())
  age            String? @db.VarChar(255)
  about_section  String? @db.VarChar(255)
  user_id        Int?
  users          users?  @relation(fields: [user_id], references: [user_id], onDelete: Restrict, onUpdate: Restrict, map: "application_ibfk_1")

  @@index([user_id], map: "user_id")
}

对于行，不带where 的findMany() 将返回表中的所有行:

Get all Records
以下 findMany 查询返回所有用户记录:

const users = await prisma.user.findMany()

---

对于列/字段，在不指定include 或select 的情况下，prisma 有一个default :

By default, when a query returns records (as opposed to a count), theresult includes the default selection set:

• All scalar fields defined in the Prisma schema (including enums)
• None of the relations

对于SELECT * FROM application(不包括users关系):

const applications = await prisma.application.findMany();

进一步在模型中包含users关系:

const applications = await prisma.application.findMany({
  include: {
    users: true // will include all fields
  }
});
