I am trying to add a new field into all documents in an existing collection.
Database name = test Collection name = teams
test.teams.update({
}
,
{
$set: {
"isGolden": false
}
}
,
false,
true)
When I am trying it with MongoChef, it is giving me the following error:
What is wrong with this? Thanks
To add field or fields to embedded documents (including documents in arrays) use the dot notation. See example. To add an element to an existing array field with $addFields , use with $concatArrays .
insertMany() method. insertMany() is a mongo shell method, which can insert multiple documents. This method can be used in the multi-document transactions. In this method, you can add documents in the collection with or without _id field.
db. collection. insertMany() can insert multiple documents into a collection.
Here mycol is our collection name, as created in the previous chapter. If the collection doesn't exist in the database, then MongoDB will create this collection and then insert a document into it. In the inserted document, if we don't specify the _id parameter, then MongoDB assigns a unique ObjectId for this document.
If you want to update all the documents, use something like this:
db.teams.update({}, {$set: {isGolden: false}}, {multi: true});
your are selecting all, setting the field isGolden
to false and making this update in all documents using multi: true
With Studio 3T you were writing queries in JSON mode in which it wants JSON data but you are not writing JSON Query. You must go to InteliShell mode in which your query will execute in format that you were writing.
