This means we can also make use of any mongo operator. The keyword new is optional in data type constructors. You can also use a wide array of mongo data type constructors such as NumberInt, NumberLong, NumberDecimal, ObjectId, ISODate, Date, LUUID, CSUUID, JUUID, PYUUID, UUID, Timestamp, Symbol, DBRef, BinDate, and HexData. As strings, they can be quoted with single-quotes (”) or double-quotes (“”), which means these two queries are the same: JSON can be used in SQL WHERE clauses in two ways: SELECT _id, foo FROM bar JSON objects in WHERE clauses To restore _id and thus make the result editable, we ask for this specific field: Which does not return _id, the result is not editable (no _id means no link to the original document). Pressing ‘Enter’ will write the new value to the database, while pressing ‘Esc’ will return the previous value and exit the editor. To edit a particular field or value in a document, simply double-click on it and a type-specific editor for that value will be activated. That is, rather than having to search for the documents you want to edit and then issue separate UPDATE, DELETE or INSERT commands, you can simply edit the documents directly inline. Edit results inlineĮditing documents and data in the SQL tab in Studio 3T is based on a ‘search and edit’ paradigm. In the screenshot above, only the first query appears underneath the SQL Query tab because it is the SQL statement executed at cursor. It shows the specific query that was actually run, important in the case of a SQL batch that contains multiple queries. The SQL Query tab shows which SQL query was executed by the text cursor (or “at cursor”). Similar to our IntelliShell, Studio 3T’s built-in mongo shell, SQL Editor detects and suggests standard SQL functions as well as fields, collections, and keyword names. SQL Query also supports smart auto-completion. Hotkey – Press F5 to execute SQL statement at cursor.Right-click – Place the cursor on the desired query, right-click, and choose Execute SQL statement at cursor.Button – Click on the Execute SQL statement marked by the cursor (play) button.You can execute a SQL statement in three ways:

To get request charges for data manipulation commands, run the getLastRequestStatistics command from a shell based UI such as Mongo shell, Robo 3T, MongoDB Compass, or a VS Code extension with shell scripting.ĭb.Download Studio 3T here and write your own SQL queries as you go through the tutorial. You can't use this editor for data manipulation commands such as insert statements. This query editor allows you to run and view request unit charges for only query predicates. Select Query Stats to display the actual request charge for the request you executed. next to the container name and select New Query.Įnter a valid query, and then select Execute Query. Go to the Data Explorer pane, and then select the container you want to work on. Use the Azure portalĬreate a new Azure Cosmos DB account and feed it with data, or select an existing account that already contains data. If you use the Azure Cosmos DB for MongoDB, you have multiple options for retrieving the RU charge. The command returns a document that contains the name of the last operation executed, its request charge, and its duration. The RU charge is exposed by a custom database command named getLastRequestStatistics.
If you're using a different API, see API for NoSQL, API for Cassandra, API for Gremlin, and API for Table articles to find the RU/s charge. This article presents the different ways you can find the request unit (RU) consumption for any operation executed against a container in Azure Cosmos DB for MongoDB. To learn more, see the request units and it's considerations article. Whether the database operation is a write, point read, or query, costs are always measured in RUs. No matter which API you use to interact with your Azure Cosmos DB container, costs are always measured by RUs. You can think of RUs as a performance currency abstracting the system resources such as CPU, IOPS, and memory that are required to perform the database operations supported by Azure Cosmos DB. Request charge is the request units consumed by all your database operations. The cost of all database operations is normalized by Azure Cosmos DB and is expressed by Request Units (or RUs, for short). Each database operation consumes system resources based on the complexity of the operation. These operations range from simple point reads and writes to complex queries. Each API has its own set of database operations. Azure Cosmos DB supports many APIs, such as SQL, MongoDB, Cassandra, Gremlin, and Table.
