B4J Question [MongoDB]Get last inserted getObjectId("_id")

[Duque]

Hi, I hope you can give me a hand.

Main.db.GetCollection(collection).Insert(documentList)

I hope to get the last inserted ObjectId...
How is it done?

I haven't touched MongoDB for a very long time, check this answer: https://stackoverflow.com/a/23077318/971547

In short, I need to find the last sorted id and limit it to 1.

Is it you want?

Dim res As List = Main.db.GetCollection(collection).Find2(Null, Null, CreateMap("_id":-1),0,1)
Log(res.Get(0))

Yes, I did, thanks.
