How to get the type of a compound query?

how would i get the type of this?

ts 
const commentsPromise = prisma.urlComments.findMany({
    where: {
      urlId,
    },
    include: {
      User: {
        select: {
          name: true,
          email: true,
          image: true,
        },
      },
    },
    orderBy: {
      createdAt: "desc",
    },
  });

  const statusCheckPromise = prisma.statusChecks.findMany({
    where: {
      urlId,
      httpCode: {
        notIn: [200, 301, 302, 303, 307, 308],
      },
    },
    orderBy: {
      createdAt: "desc",
    },
  });

  const [comments, statusChecks] = await prisma.$transaction([
    commentsPromise,
    statusCheckPromise,
  ]);

ts 
const commentsPromise = prisma.urlComments.findMany({
    where: {
      urlId,
    },
    include: {
      User: {
        select: {
          name: true,
          email: true,
          image: true,
        },
      },
    },
    orderBy: {
      createdAt: "desc",
    },
  });

  const statusCheckPromise = prisma.statusChecks.findMany({
    where: {
      urlId,
      httpCode: {
        notIn: [200, 301, 302, 303, 307, 308],
      },
    },
    orderBy: {
      createdAt: "desc",
    },
  });

  const [comments, statusChecks] = await prisma.$transaction([
    commentsPromise,
    statusCheckPromise,
  ]);

What type exactly are you looking to get? The return of both statusCheckPromise as well as commentsPromise?

In situations like that isnt just easier to infer types from the code? Or use typeof

@Enzonaki how do you infer the types from the code? or use type of?

type Comments = typeof comments but that only works if you define the type inside the function. If you want it outside its best to abstract the query to its own function.

async function getComments() {
  return await prisma.statusChecks.findMany({
    where: {
      urlId,
      httpCode: {
        notIn: [200, 301, 302, 303, 307, 308],
      },
    },
    orderBy: {
      createdAt: "desc",
    },
  });
}

type Comments = Awaited<ReturnType<typeof getComments>>

async function getComments() {
  return await prisma.statusChecks.findMany({
    where: {
      urlId,
      httpCode: {
        notIn: [200, 301, 302, 303, 307, 308],
      },
    },
    orderBy: {
      createdAt: "desc",
    },
  });
}

type Comments = Awaited<ReturnType<typeof getComments>>
