Trying to create an azure datawarehouse using powershell and want to import sample adventureworks data in it using powershell. Passing samplename parameter as "AdventureworksLT". But when the Dataware house is created,there are no adventureworks tables in datawarehouse.

This is the guide which I'm referring: https://video2.skills-academy.com/en-us/powershell/module/az.sql/new-azsqldatabase?view=azps-4.7.0

Sample script:

READ VALUE FROM A CSV FILE

$csv = Import-csv ".\Config.csv"

$csv | ForEach-Object {
$ResourceGroup = $.ResourceGroup
$Region = $.Region
$Subscription = $_.Subscription

}
"$ResourceGroup - $Region - $Subscription"

Connect to Azure Account

Connect-AzAccount

Get-AzSubscription

Set-AzContext -SubscriptionName $Subscription

The data center and resource name for your resources

$resourcegroupname = $ResourceGroup
$location = $Region

The server name: Use a random value or replace with your own value (don't capitalize)

$servername = "server-$(Get-Random)"

Set an admin name and password for your database

The sign-in information for the server

$adminlogin = "ServerAdmin"
$password = "ChangeYourAdminPassword1"

The ip address range that you want to allow to access your server - change as appropriate

$startip = "0.0.0.0"
$endip = "255.255.255.255"

The database name

$databasename = "UBSampleDataWarehouse"

CREATE RG

New-AzResourceGroup -Name $resourcegroupname -Location $location

CREATESERVER

New-AzSqlServer -ResourceGroupName $resourcegroupname \-ServerName $servername
-Location $location `
-SqlAdministratorCredentials $(New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList $adminlogin, $(ConvertTo-SecureString -String $password -AsPlainText -Force))

CREATE FIREWALLRULE

New-AzSqlServerFirewallRule -ResourceGroupName $resourcegroupname \-ServerName $servername
-FirewallRuleName "AllowSome" -StartIpAddress $startip -EndIpAddress $endip

CREATEDB

New-AzSqlDatabase \-ResourceGroupName $resourcegroupname
-ServerName $servername \-DatabaseName $databasename
-Edition "DataWarehouse" \-RequestedServiceObjectiveName "DW100c"
-CollationName "SQL_Latin1_General_CP1_CI_AS" \-MaxSizeBytes 10995116277760
-SampleName "AdventureWorksLT" `

ECHO "DATAWARE HOUSE CREATED SUCCESSFULLY"

Please help me further
