I am very new to mongoDB.

i have this collection here:

{ name: Peter salary: 3000 }, { name: Marry salary: 2000 }, { name: Sally salary: 1000 }

What should I do if I want to increase all salaries by 500?

I tried db.bounties.update({},{$inc: { salary: 500}}) but only the first one got updated

there're two ways

1- use updateMany it means Updates all documents that match the specified filter for a collection

db.bounties.updateMany({},{$inc: { salary: 500}})

2- use update with multi parameter

db.bounties.update({},{$inc: { salary: 500}},{multi:true})
