您可以使用以下方法执行保存在Azure运行手册中的Azure blob存储中的文件中的SQL。

# The accountName and accountKey are needed to get into the storage account.
# I recommend saving these as credentials in the automation account
$accountName = "xxxxxxxxxxxxx"
$accountKey = "yyyyyyyyyyyyyyyyyyy"
$containerName = "container-name"
$sqlFile = "sql-file.sql"

$context = New-AzStorageContext -StorageAccountName $accountName -StorageAccountKey $accountKey
$container_client = Get-AzStorageContainer -Name $containerName -Context $context
$source_blob_client = $container_client.CloudBlobContainer.GetBlockBlobReference($sqlFile)

#download the blob as text into memory
$sqlFromFile = $source_blob_client.DownloadText()

# The following 'MyCredential' is saved a credential in the automation account   
$SQLServerCred = Get-AutomationPSCredential -Name 'MyCredential'
#Import the SQL Server Name from the Automation variable.
$SQL_Server_Name = "myhsm-db-eu.database.windows.net"
#Import the SQL DB from the Automation variable.
$SQL_DB_Name = "db_name"

# Execute query
invoke-sqlcmd -ServerInstance "$SQL_Server_Name" -Database "$SQL_DB_Name" -Credential $SQLServerCred -Query "$sqlFromFile"

希望这能帮上忙。谢谢
