![]() ![]() Now that you've created a database, use the next guide to create containers. Once returned, you can parse response properties and then eventually get the underlying Database object: // New instance of Database response class referencing the server-side databaseĭatabaseResponse response = await client.CreateDatabaseIfNotExistsAsync( The following example shows the CosmosClient.CreateDatabaseIfNotExistsAsync method returning a DatabaseResponse. The true return type for the CosmosClient.CreateDatabaseAsync and CosmosClient.CreateDatabaseIfNotExistsAsync methods is DatabaseResponse. You may want to parse metadata about the response including headers and the HTTP status code. In all examples so far, the response from the asynchronous request was cast immediately to the Database type. This method is useful for avoiding errors if you run the same code multiple times. The CosmosClient.CreateDatabaseIfNotExistsAsync method will only create a new database if it doesn't already exist. The following example creates a database asynchronously only if it doesn't already exist on the account: // New instance of Database class referencing the server-side databaseĭatabase database2 = await client.CreateDatabaseIfNotExistsAsync( Create a database asynchronously if it doesn't already exist Learn about the benefits and disadvantages of Azure Cosmos DB. The CosmosClient.CreateDatabaseAsync method will throw an exception if a database with the same name already exists. Azure Cosmos DB is a globally distributed, JSON-based database delivered as a ‘Platform as a Service’ (PaaS) in Microsoft Azure. ![]() The following example creates a database asynchronously: // New instance of Database class referencing the server-side databaseĭatabase database1 = await client.CreateDatabaseAsync( Abstract Beings, Abstract Deities, Abstracts, Cosmic Abstracts, Cosmic Aspects, Cosmic Embodiments, Cosmic Presences, Universal Abstracts, Universal Constants Affiliation and Identity Physical Characteristics Origin and Status Creators and Appearances Creators Stan Lee, Steve Ditko First Strange Tales 138 ( August, 1965) Order. To create a database, call one of the following methods: Once created, the URI for a database is in this format: Database names must start with a lowercase letter or number. COSMOS DB provided a cosmetics inventory as well as other regulatory inventories, accompanied by assessment results and in vitro and in vivo toxicity data.Database names can only contain lowercase letters, numbers, or the dash (-) character.Keep database names between 3 and 63 characters long.Here are some quick rules when naming a database: When you create a database, the database name forms a segment of the URI used to access the database resource and any child resources. In Azure Cosmos DB, a database is analogous to a namespace. Before you can create or manage containers, you must first create a database. Databases in Azure Cosmos DB are units of management for one or more containers. ![]()
