Important

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

If you don't have an Azure subscription, create a free account.
Sign in to the Azure portal.
Create an Azure IoT Hub.
Create an Azure IoT Edge device.

Note

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

Deploy SQL Edge Module from Azure Marketplace

Azure Marketplace is an online applications and services marketplace where you can browse through a wide range of enterprise applications and solutions that are certified and optimized to run on Azure, including IoT Edge modules. Azure SQL Edge can be deployed to an edge device through the marketplace.

Find the Azure SQL Edge module on the Azure Marketplace.
Pick the software plan that best matches your requirements and select Create.

On the Target Devices for IoT Edge Module page, specify the following details and then select Create.

Field	Description
Subscription	The Azure subscription under which the IoT Hub was created
IoT Hub	Name of the IoT Hub where the IoT Edge device is registered and then select "Deploy to a device" option
IoT Edge Device Name	Name of the IoT Edge device where SQL Edge would be deployed

On the Set Modules on device: page, select the Azure SQL Edge module under IoT Edge Modules. The default module name is set to AzureSQLEdge.
On the Module Settings section of the Update IoT Edge Module pane, specify the desired values for the IoT Edge Module Name, Restart Policy and Desired Status.

Important

Don't change or update the Image URI settings on the module.

On the Environment Variables section of the Update IoT Edge Module pane, specify the desired values for the environment variables. For a complete list of Azure SQL Edge environment variables, see Configure using environment variables. The following default environment variables are defined for the module.

Parameter	Description
MSSQL_SA_PASSWORD	Change the default value to specify a strong password for the SQL Edge admin account.
MSSQL_LCID	Change the default value to set the desired language ID to use for SQL Edge. For example, 1036 is French.
MSSQL_COLLATION	Change the default value to set the default collation for SQL Edge. This setting overrides the default mapping of language ID (LCID) to collation.

Important

Don't change or update the ACCEPT_EULA environment variable for the module.

On the Container Create Options section of the Update IoT Edge Module pane, update the following 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

Don't change the PlanId environment variable defined in the create config setting. If this value is changed, the Azure SQL Edge container will fail to start.

Warning

If you reinstall the module, remember to remove any existing bindings first, otherwise your environment variables will not be updated.
On the Update IoT Edge Module pane, select Update.
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.
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.

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"
```
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.
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.

From the sqlcmd command prompt, paste the following Transact-SQL command to create a test database:
```
CREATE DATABASE TestDB;
GO
```
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.

From the sqlcmd command prompt, switch context to the new TestDB database:
```
USE TestDB;
```

Create new table named Inventory:

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

Insert data into the new table:

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

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

Type GO to execute the previous commands:
```
GO
```

Select data

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

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;
```
Execute the command:
```
GO
```

Exit the sqlcmd command prompt

To end your sqlcmd session, type QUIT:
```
QUIT
```
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.
