Deploy Azure SQL Edge

  • Άρθρο

Important

Azure SQL Edge will be retired on September 30, 2025. For more information and migration options, see the Retirement notice.

Note

Azure SQL Edge no longer supports the ARM64 platform.

Azure SQL Edge is a relational database engine optimized for IoT and Azure IoT Edge deployments. It provides capabilities to create a high-performance data storage and processing layer for IoT applications and solutions. This quickstart shows you how to get started with creating an Azure SQL Edge module through Azure IoT Edge using the Azure portal.

Before you begin

Note

To deploy an Azure Linux VM as an IoT Edge device, see this quickstart guide.

Deploy Azure SQL Edge Module using IoT Hub

Azure SQL Edge can be deployed using instructions from Deploy modules from Azure portal. The image URI for Azure SQL Edge is mcr.microsoft.com/azure-sql-edge:latest.

  1. On the Add IoT Edge Module page, specify the desired values for the IoT Edge Module Name, Image URI, Restart Policy and Desired Status.

    Use the following image URI depending on the edition you want to deploy:

    • Developer edition - mcr.microsoft.com/azure-sql-edge/developer
    • Premium edition - mcr.microsoft.com/azure-sql-edge/premium

  2. On the Environment Variables section of the Add IoT Edge Module page, specify the desired values for the environment variables. For a complete list of Azure SQL Edge environment variables, see Configure using environment variables.

    Parameter Description
    ACCEPT_EULA Set this value to Y to accept the End-User Licensing Agreement
    MSSQL_SA_PASSWORD Set the value to specify a strong password for the SQL Edge admin account.
    MSSQL_LCID Set the value to set the desired language ID to use for SQL Edge. For example, 1036 is French.
    MSSQL_COLLATION Set the value to set the default collation for SQL Edge. This setting overrides the default mapping of language ID (LCID) to collation.

  3. On the Container Create Options section of the Add IoT Edge Module page, set the options as per requirement.

    • Host Port

      Map the specified host port to port 1433 (default SQL port) in the container.

    • Binds and Mounts

      If you need to deploy more than one SQL Edge module, ensure that you update the mounts option to create a new source and target pair for the persistent volume. For more information on mounts and volume, see Use volumes on Docker documentation.

    {
    "HostConfig": {
        "CapAdd": [
            "SYS_PTRACE"
        ],
        "Binds": [
            "sqlvolume:/sqlvolume"
        ],
        "PortBindings": {
            "1433/tcp": [
                {
                    "HostPort": "1433"
                }
            ]
        },
        "Mounts": [
            {
                "Type": "volume",
                "Source": "sqlvolume",
                "Target": "/var/opt/mssql"
            }
        ]
    },
    "Env": [
        "MSSQL_AGENT_ENABLED=TRUE",
        "ClientTransportType=AMQP_TCP_Only",
        "PlanId=asde-developer-on-iot-edge"
    ]
}

    Important

    Set the PlanId environment variable based on the edition installed.

    • Developer edition - asde-developer-on-iot-edge
    • Premium edition - asde-premium-on-iot-edge

    If this value is set incorrectly, the Azure SQL Edge container fails to start.

    Warning

    If you reinstall the module, remember to remove any existing bindings first, otherwise your environment variables will not be updated.

  4. On the Add IoT Edge Module page, select Add.

  5. On the Set modules on device page, select Next: Routes > if you need to define routes for your deployment. Otherwise select Review + Create. For more information on configuring routes, see Deploy modules and establish routes in IoT Edge.

  6. On the Set modules on device page, select Create.

Connect to Azure SQL Edge

The following steps use the Azure SQL Edge command-line tool, sqlcmd, inside the container to connect to Azure SQL Edge.

Note

SQL Server command line tools, including sqlcmd, aren't available inside the ARM64 version of Azure SQL Edge containers.

  1. Use the docker exec -it command to start an interactive bash shell inside your running container. In the following example, AzureSQLEdge is name specified by the Name parameter of your IoT Edge Module.

    sudo docker exec -it AzureSQLEdge "bash"

  2. Once inside the container, connect locally with the sqlcmd tool. sqlcmd isn't in the path by default, so you have to specify the full path.

    /opt/mssql-tools/bin/sqlcmd -S localhost -U SA -P "<YourNewStrong@Passw0rd>"

    Tip

    You can omit the password on the command-line to be prompted to enter it.

  3. If successful, you should get to a sqlcmd command prompt: 1>.

Create and query data

The following sections walk you through using sqlcmd and Transact-SQL to create a new database, add data, and run a query.

Create a new database

The following steps create a new database named TestDB.

  1. From the sqlcmd command prompt, paste the following Transact-SQL command to create a test database:

    CREATE DATABASE TestDB;
GO

  2. On the next line, write a query to return the name of all of the databases on your server:

    SELECT name from sys.databases;
GO

Insert data

Next, create a new table called Inventory, and insert two new rows.

  1. From the sqlcmd command prompt, switch context to the new TestDB database:

    USE TestDB;

  2. Create new table named Inventory:

    CREATE TABLE Inventory (id INT, name NVARCHAR(50), quantity INT)

  3. Insert data into the new table:

    INSERT INTO Inventory
VALUES (1, 'banana', 150);

INSERT INTO Inventory
VALUES (2, 'orange', 154);

  4. Type GO to execute the previous commands:

    GO

Select data

Now, run a query to return data from the Inventory table.

  1. From the sqlcmd command prompt, enter a query that returns rows from the Inventory table where the quantity is greater than 152:

    SELECT * FROM Inventory WHERE quantity > 152;

  2. Execute the command:

    GO

Exit the sqlcmd command prompt

  1. To end your sqlcmd session, type QUIT:

    QUIT

  2. To exit the interactive command-prompt in your container, type exit. Your container continues to run after you exit the interactive bash shell.

Connect from outside the container

You can connect and run SQL queries against your Azure SQL Edge instance from any external Linux, Windows, or macOS tool that supports SQL connections. For more information on connecting to a SQL Edge container from outside, see Connect and Query Azure SQL Edge.

In this quickstart, you deployed a SQL Edge Module on an IoT Edge device.
