mongodb - Mongo DB find() query error -

i new mongodb. have collection called person. i'm trying records without _id field query:

db.person.find({}{_id:0})

but error

syntax error: unexpected {

but if write

db.person.find()

it works perfectly.

consider following documents inserted in person collection

db.person.insert({"name":"abc"}) db.person.insert({"name":"xyz"}

if want find exact matching use query

db.person.find({"name":"abc"})

this return matched name documents

if want names without _id use projeciton id query

db.person.find({},{"_id":0})

which return

{ "name" : "abc" } { "name" : "xyz" }
