Description
We usually try to treat null and missing fields mostly the same, so this seems like surprising behavior.
MongoDB Enterprise asdf:PRIMARY> db.foo.insert({_id: 1, b: null})
|
WriteResult({ "nInserted" : 1 })
|
MongoDB Enterprise asdf:PRIMARY> db.foo.update({_id: 1}, {$inc: {a: 1}})
|
WriteResult({ "nMatched" : 1, "nUpserted" : 0, "nModified" : 1 })
|
MongoDB Enterprise asdf:PRIMARY> db.foo.update({_id: 1}, {$inc: {b: 1}})
|
WriteResult({
|
"nMatched" : 0,
|
"nUpserted" : 0,
|
"nModified" : 0,
|
"writeError" : {
|
"code" : 14,
|
"errmsg" : "Cannot apply $inc to a value of non-numeric type. {_id: 1.0} has the field 'b' of non-numeric type null"
|
}
|
})
