Implement database-scoped configuration

Database-scoped configuration is a powerful feature in Microsoft Azure SQL Solutions that allows administrators to define and manage configuration settings at the database level. This enables better control over database behavior and simplifies the process of managing multiple databases with different requirements. In this article, we will explore how to implement database-scoped configuration in Azure SQL Solutions.

Getting Started

To get started, let’s assume you have an Azure SQL database and you need to configure a specific behavior for it. You can use the following steps to implement database-scoped configuration:

1. Connect to your Azure SQL database using tools like Azure Portal or SSMS (SQL Server Management Studio).
2. Create a new T-SQL script or open an existing script to define the configuration settings. You can alternatively use Powershell or Azure CLI to deploy the configuration.
3. At the top of your script, add the USE statement followed by the name of the target database. This ensures that the configuration settings are applied to the correct database.

USE YourDatabaseName;

4. Define the configuration settings using the ALTER DATABASE SCOPED CONFIGURATION statement. This statement allows you to modify various database settings.

ALTER DATABASE SCOPED CONFIGURATION
SET MAXDOP = 4, LEGACY_CARDINALITY_ESTIMATION = ON;

In the example above, we set the maximum degree of parallelism (MAXDOP) to 4 and enable the legacy cardinality estimation (LEGACY_CARDINALITY_ESTIMATION).

You can refer to the Azure SQL database documentation for a complete list of available configuration options and their descriptions.

5. Execute the script to apply the configuration settings to the database. You can do this by running the script in SSMS or using Azure CLI or Azure Portal.

If you are using SSMS, select the script and click the “Execute” button. This will execute the script and apply the database-scoped configuration settings.

If you are using Azure CLI, run the following command:

az sql db execute-maintenance-mode -g YourResourceGroup -s YourSqlServer -d YourDatabase --execute --script "YourScript.sql"

Replace YourResourceGroup, YourSqlServer, YourDatabase, and YourScript.sql with your actual values.

If you are using Azure Portal, you can navigate to the “Query editor (preview)” for your database and execute the script there.

6. Verify that the configuration settings have been applied by querying the system view sys.database_scoped_configurations. This view provides information about the current configuration settings for the database.

SELECT * FROM sys.database_scoped_configurations;

This query will display the configuration settings for the database, including the values you just set.

Congratulations! You have successfully implemented database-scoped configuration for your Azure SQL database. You can now define and manage various configuration settings at the database level, providing fine-grained control over database behavior.

Remember that database-scoped configuration settings override any server-level settings. This allows you to customize the behavior of individual databases as per their requirements. It is important to carefully plan and test the configuration settings before applying them to production databases.

In conclusion, by implementing database-scoped configuration in Azure SQL Solutions, administrators can easily manage and modify configuration settings at the database level. This feature provides flexibility and control over the behavior of individual databases, enabling efficient management of Azure SQL environments.
