MongoDB collection hyphenated name
Use this syntax:
db['repl-failOver'].find({})or
db.getCollection('repl-failOver').find({})You can find more information in the Executing Queries section of the manual:
If the mongo shell does not accept the name of the collection, for instance if the name contains a space, hyphen, or starts with a number, you can use an alternate syntax to refer to the collection, as in the following:
db["3test"].find()db.getCollection("3test").find()
You are getting this error from accessing collections with specific characters (-, _, ). I explained the workaround here, but basically all you need is to do
db.getCollection("repl-failOver").insert(...)
