Jun 13, 2022 · Find Specific Documents. In order to fetch a specific document from the MongoDB collection, we can use a query parameter in the find method. This parameter will help us to fetch only that record which meets the criteria. In the following example, we are going to fetch the record by staff ID, where the staff ID is equal three and it will return. Best Java code snippets using com.mongodb.client. FindIterable.forEach (Showing top 20 results out of 315) com.mongodb.client FindIterable forEach. Example #1 Reading a result set. MongoDB\Driver\Manager::executeCommand () and MongoDB\Driver\Manager::executeQuery () both return their result (s) as a MongoDB\Driver\Cursor object.

ForEach is a PowerShell statement used to use iterate or loop over the given list, array or collection of the objects, strings, numbers, etc. ForEach is a very popular loop mechanism where we can use different cases like loop through files, Numbers, Strings, Processes, etc. Powershell version 4.0 brings some performance improvements to the ForEach loop. Example. This example demonstrates Parallel.ForEach for CPU intensive operations. When you run the example, it randomly generates 2 million numbers and tries to filter to prime numbers. The first case iterates over the collection via a for loop. The second case iterates over the collection via Parallel.ForEach.The resulting time taken by each iteration is displayed when the application is. mongodump utility is used to export the content of the MongoDB database as a backup.
