What is the short way of getting back a complex record that was inserted or updated with ids included?

Sorry if the title is not clear

Suppose a main item has a 1-to-n or n-to-n relationship with 5-6 other tables

const {
        genres,
        credits,
        similar,
        keywords,
        ...mainItem
      } = item
      ;
await db.transaction(async (tx: any) => {
        const insertedMainItem = await tx
          .insert(mainItemTable)
          .values(mainItem)
          .onConflictDoUpdate({

in the same transaction, i write to the other tables and joinTables with new methods.

I currently call returning* to get back the primary key

.returning({ id: mainItemTable.id });

* (from the docs for sqlite driver. theres another callback called output() but i think thats exclusive to MSSQL?)

however, i dont just want a subset of the saved data. i'd like the full object back with their primary ids in the original structure that it was provided. with a spread operator most likely

performing upsert-read cycles on every item or stitching together the sum of its parts seems like the only way?

please advise

Thank you
