Use PowerShell to create elastic pools and move databases between elastic pools

This PowerShell script example creates two elastic pools and moves a database from one elastic pool into another elastic pool, and then moves a database out of an elastic pool to a single database compute size.

If you don't have an Azure subscription, create a free account before you begin.

Note

This article has been updated to use the new Azure PowerShell Az module. You can still use the AzureRM module, which will continue to receive bug fixes until at least December 2020. To learn more about the new Az module and AzureRM compatibility, see Introducing the new Azure PowerShell Az module. For Az module installation instructions, see Install Azure PowerShell.

Use Azure Cloud Shell

Azure hosts Azure Cloud Shell, an interactive shell environment that you can use through your browser. Cloud Shell lets you use either bash or PowerShell to work with Azure services. You can use the Cloud Shell pre-installed commands to run the code in this article without having to install anything on your local environment.

To launch Azure Cloud Shell:

Option Example/Link
Select Try It in the upper-right corner of a code block. Selecting Try It doesn't automatically copy the code to Cloud Shell. Example of Try It for Azure Cloud Shell
Go to https://shell.azure.com or select the Launch Cloud Shell button to open Cloud Shell in your browser. Launch Cloud Shell in a new window
Select the Cloud Shell button on the top-right menu bar in the Azure portal. Cloud Shell button in the Azure portal

To run the code in this article in Azure Cloud Shell:

  1. Launch Cloud Shell.

  2. Select the Copy button on a code block to copy the code.

  3. Paste the code into the Cloud Shell session with Ctrl+Shift+V on Windows and Linux, or Cmd+Shift+V on macOS.

  4. Press Enter to run the code.

If you choose to install and use the PowerShell locally, this tutorial requires AZ PowerShell 1.4.0 or later. If you need to upgrade, see Install Azure PowerShell module. If you are running PowerShell locally, you also need to run Connect-AzAccount to create a connection with Azure.

Sample script

# Connect-AzAccount
$SubscriptionId = '<replace with your subscription id>'
# Set the resource group name and location for your server
$resourceGroupName = "myResourceGroup-$(Get-Random)"
$location = "westus2"
# Set elastic pool names
$firstPoolName = "MyFirstPool"
$secondPoolName = "MySecondPool"
# Set an admin login and password for your server
$adminSqlLogin = "SqlAdmin"
$password = "<EnterYourComplexPasswordHere>"
# The logical server name has to be unique in the system
$serverName = "server-$(Get-Random)"
# The sample database names
$firstDatabaseName = "myFirstSampleDatabase"
$secondDatabaseName = "mySecondSampleDatabase"
# The ip address range that you want to allow to access your server
$startIp = "0.0.0.0"
$endIp = "0.0.0.0"

# Set subscription 
Set-AzContext -SubscriptionId $subscriptionId 

# Create a new resource group
$resourceGroup = New-AzResourceGroup -Name $resourceGroupName -Location $location

# Create a new server with a system wide unique server name
$server = New-AzSqlServer -ResourceGroupName $resourceGroupName `
    -ServerName $serverName `
    -Location $location `
    -SqlAdministratorCredentials $(New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList $adminSqlLogin, $(ConvertTo-SecureString -String $password -AsPlainText -Force))

# Create a server firewall rule that allows access from the specified IP range
$serverFirewallRule = New-AzSqlServerFirewallRule -ResourceGroupName $resourceGroupName `
    -ServerName $serverName `
    -FirewallRuleName "AllowedIPs" -StartIpAddress $startIp -EndIpAddress $endIp

# Create two elastic database pools
$firstPool = New-AzSqlElasticPool -ResourceGroupName $resourceGroupName `
    -ServerName $servername `
    -ElasticPoolName $firstPoolName `
    -Edition "Standard" `
    -Dtu 50 `
    -DatabaseDtuMin 10 `
    -DatabaseDtuMax 20
$secondPool = New-AzSqlElasticPool -ResourceGroupName $resourceGroupName `
    -ServerName $serverName `
    -ElasticPoolName $secondPoolName `
    -Edition "Standard" `
    -Dtu 50 `
    -DatabaseDtuMin 10 `
    -DatabaseDtuMax 50

# Create two blank databases in the first pool
$firstDatabase = New-AzSqlDatabase  -ResourceGroupName $resourceGroupName `
    -ServerName $serverName `
    -DatabaseName $firstDatabaseName `
    -ElasticPoolName $firstPoolName
$secondDatabase = New-AzSqlDatabase  -ResourceGroupName $resourceGroupName `
    -ServerName $serverName `
    -DatabaseName $secondDatabaseName `
    -ElasticPoolName $secondPoolName

# Move the database to the second pool
$firstDatabase = Set-AzSqlDatabase -ResourceGroupName $resourceGroupName `
    -ServerName $serverName `
    -DatabaseName $firstDatabaseName `
    -ElasticPoolName $secondPoolName

# Move the database into a standalone performance level
$firstDatabase = Set-AzSqlDatabase -ResourceGroupName $resourceGroupName `
    -ServerName $serverName `
    -DatabaseName $firstDatabaseName `
    -RequestedServiceObjectiveName "S0"

# Clean up deployment 
# Remove-AzResourceGroup -ResourceGroupName $resourceGroupName

Clean up deployment

Use the following command to remove the resource group and all resources associated with it.

Remove-AzResourceGroup -ResourceGroupName $resourcegroupname

Script explanation

This script uses the following commands. Each command in the table links to command specific documentation.

Command Notes
New-AzResourceGroup Creates a resource group in which all resources are stored.
New-AzSqlServer Creates a SQL Database server that hosts a single database or an elastic pool.
New-AzSqlElasticPool Creates an elastic pool.
New-AzSqlDatabase Creates a database in a SQL Database server as a standalone or a pooled database.
Set-AzSqlDatabase Updates database properties or moves a database into, out of, or between elastic pools.
Remove-AzResourceGroup Deletes a resource group including all nested resources.
