const users = await prisma.user.findMany({
  select: {
    id: true,
    name: true,
    email: true,
  },
});

const result = await prisma.$transaction(async (tx) => {
  const user = await tx.user.create({
    data: { email, name },
  });

  await tx.post.create({
    data: { title: "Welcome!", authorId: user.id },
  });

  return user;
});

prisma.$use(async (params, next) => {
  if (params.action === "delete") {
    params.action = "update";
    params.args.data = { deletedAt: new Date() };
  }
  return next(params);
