MongoDB Actions¶
The following actions are available for MongoDB in functions and in the client SDKs.
Important
In order to use MongoDB actions, you must have rules set up for each namespace included in the operation.
| Action | Description |
|---|---|
mongodb.db() |
Return a database handle object that represents a database in a
linked MongoDB Cluster. Call
database.collection() on the database handle to
retrieve a collection handle. |
database.collection() |
Return a collection handle object that represents a collection
in a database. |
collection.find() |
Find all documents in a collection or view that match the provided query predicates and return a cursor that points to them. |
collection.findOne() |
Return a single document from a collection or view. If multiple documents satisfy the query, this method returns the first document according to the query’s sort order or natural order. |
collection.findOneAndUpdate() |
Update a single document in a collection or view based on a query filter and return the document
in either its pre-update or post-update form. Unlike
collection.updateOne(), this action allows you to
atomically find, update, and return a document with the same
command. |
collection.findOneAndReplace() |
Overwrite a single document in a collection or view based on a query filter and return the document
in either its pre-replacement or post-replacement form. Unlike
collection.updateOne(), this action allows you to
atomically find, replace, and return a document with the same
command. |
collection.findOneAndDelete() |
Remove a single document from a collection based on a query
filter and return a document with the same form as the
document immediately before it was deleted. Unlike
collection.deleteOne(), this action allows you to
atomically find and delete a document with the same command. |
collection.count() |
Return the number of documents in a collection or view that match the specified query filter. |
collection.insertOne() |
Insert a single document into a collection and return the _id of the
inserted document. |
collection.insertMany() |
Insert one or more documents into a collection and return a list of the
_id values for each inserted document. |
collection.updateOne() |
Update a single document in a collection based on a query filter. |
collection.updateMany() |
Update one or more documents in a collection based on a query filter. |
collection.deleteOne() |
Remove a single document from the collection based on a query filter. |
collection.deleteMany() |
Remove one or more documents from the collection based on a query filter. |
collection.aggregate() |
Execute an aggregation pipeline and return a cursor that points to the result. |
