You can also do:

await ctx.db.patch(data._id, { flight_id: args.new_flight_id });

await ctx.db.patch(data._id, { flight_id: args.new_flight_id });

What do you mean by "check update status" exactly?

I need to give feedback on whether the data has been updated or not. How can I do that? What is the difference between replace and patch? Why should I use Patch?

Patch vs replace: https://docs.convex.dev/database/writing-data#updating-existing-documents Whether it's been updated:

const existing = await ctx.db.get(data._id);
const changed = existing.flight_id !== args.new_flight_id;
await ctx.db.patch(data._id, { flight_id: args.new_flight_id });
return changed;

const existing = await ctx.db.get(data._id);
const changed = existing.flight_id !== args.new_flight_id;
await ctx.db.patch(data._id, { flight_id: args.new_flight_id });
return changed;
