how to update collection without using objectid

[Asif]

Hi,
I have to update rows of a collection, but i dont have the object id saved, instead of that i have another value of that collection. Is there a way to update the collection without using object id.

Hello!

No, you have to know object id to update collection. You can do request to DB using "another value of that collection", retrieve _id and using that _id do an update.
