MergeStageWhenNotMatched Enumeration

The behavior of $merge if a result document does not match an existing document in the output collection.

Namespace: MongoDB.Driver
Assembly: MongoDB.Driver (in MongoDB.Driver.dll) Version: 2.14.0+2b37a1fe1cbdbe1a020b52b77f1197b6d77575e7

Syntax

Copy

public enum MergeStageWhenNotMatched

Public Enumeration MergeStageWhenNotMatched

type MergeStageWhenNotMatched

Members

Member name	Value	Description
Insert	0	Insert the document into the output collection.
Discard	1	Discard the document; i.e. $merge does not insert the document into the output collection.
Fail	2	Stop and fail the aggregation operation. Any changes to the output collection from previous documents are not reverted.
