I also verified multiple times that I don’t have a typo somewhere: The collection I see at Cluster -> Collections in the webinterface is definitely called test. The version of Compass is 1.21.2 and thereby above 1.12.Īfter adding the string to Compass, it added some things like “…Compass&retryWrites=true&ssl=true” which look to me like simply the default parameters. One of the most straightforward ways to rename a MongoDB collection is by using the db.collection.renameCollection() method. ![]() The end of the connection string also shows /test, so the correct database is addressed. We will perform Rename a field/property for all the documents in the database and we will also see Rename specific field/property conditionally We will cover. If it’s important: I simply copied the connection string from Cluster -> Connect -> Connect using MongoDB Compass and filled in the credentials.

Only when I grant readWrite for the whole database I can see all Collections, even empty ones, in Compass. Still, I can’t see any Collection with the user in Compass, also when setting the privilege to a different non-empty Collection. (Also if I change the privilege to a different Collection for the user and try again through the api, I get an appropriate error from Atlas, so I’m definetely accessing via said user) ![]() Accordingly the user does have write access to the collection and the privileges work correctly. There are several documents in testcollection, added at first through the atlas webinterface but later on also successfully with the user in question through the api. In MongoDB, indexes are defined in the collection level and indexes on any field or subfield of the documents in a collection are supported.įor this tutorial, we’ll use the following data set to demonstrate the indexing functionality of MongoDB.Sorry, I should’ve mentioned that in advance: This ordering helps to perform equality matches and range-based query operations efficiently. These values are used to order the indexed fields. In simplest terms, indexes store the values of the indexed fields outside the table or collection and keep track of their location in the disk. Indexes are special data structures that store a small part of the Collection’s data in a way that can be queried easily. ![]() Use the right-hand menu to navigate.) What are indexes in MongoDB? db.originalCollectionName.renameCollection ('newCollectionName') For instance, if your existing collection name is 'demo' and want to rename to 'demoupdated' then, the query would be as follows:- db.demo. Next, provide the following details: Indicate whether you are creating a new database or using an existing one. Open the Data Explorer pane, and select New Container. The value of dropTarget is set as True, this means that if an existing collection collec existed, then the new collection would overwrite the existing collection’s data. Create a new Azure Cosmos DB account, or select an existing account. (This article is part of our MongoDB Guide. You can use the following syntax to rename an existing collection in MongoDB. The rename () function will rename the collection name from collection to collec. In this tutorial, I’ll walk you through different types of indexes and show you how to create and manage indexes in MongoDB. By limiting the number of documents to be queried, you’ll increases the overall performance of the application. Significantly slow down your applicationįortunately, using indexes fixes both these issues.Result in various performance bottlenecks.Paste the copied collections, views, and buckets into the new database. Copy the original database by copying all the collections, views, and buckets. In MongoDB, querying without indexes is called a collection scan. The procedures below demonstrate how to rename a database in MongoDB using the MongoDB GUI. When querying data without indexes, the query will have to search for all the records within a database to find data that match the query. Indexes provide users with an efficient way of querying data.
