问题描述
我正在尝试开始将SQL Azure数据库导出到Blob.但是，在尝试了不同的方法并搜索了网络之后，我找不到找到使之工作的方法.
I am trying to start an export of a SQL Azure database to a blob. However, after trying different approaches and searching the web I can't find a way to make it work.
$exportRequest = Start-AzureSqlDatabaseExport -SqlConnectionContext $SqlContext -StorageContainer $Container -DatabaseName 'Users' -BlobName 'autobackupotest.bacpac' -Verbose -Debug
上面的行显示为:
DEBUG: 2:05:14 PM - StartAzureSqlDatabaseExport begin processing with ParameterSet 'ByContainerObject'.

我验证了用于此cmdlet的变量，它们不为null.在该cmdlet之前，我使用以下代码:
I verified the variables I use for this cmdlet and they are not null. Prior to that cmdlet I use the following code:
Import-Module Azure
Import-Module Azure.Storage
Get-AzureRmSubscription –SubscriptionName "Production" | Select-AzureRmSubscription
# Username for Azure SQL Database server
$ServerLogin = "username"
# Password for Azure SQL Database server
$serverPassword = ConvertTo-SecureString "abcd" -AsPlainText -Force
# Establish credentials for Azure SQL Database Server
$ServerCredential = new-object System.Management.Automation.PSCredential($ServerLogin, $serverPassword)
# Create connection context for Azure SQL Database server
$SqlContext = New-AzureSqlDatabaseServerContext -FullyQualifiedServerName "myspecialsqlserver.database.windows.net" -Credential $ServerCredential
$StorageContext = New-AzureStorageContext -StorageAccountName 'prodwad' -StorageAccountKey 'xxxxx'
$Container = Get-AzureStorageContainer -Name 'automateddbbackups' -Context $StorageContext
$exportRequest = Start-AzureSqlDatabaseExport -SqlConnectionContext $SqlContext -StorageContainer $Container -DatabaseName 'Users' -BlobName 'autobackupotest.bacpac' -Verbose -Debug
这可能是什么问题?该异常消息未提供任何详细信息.
What could be wrong here? That exception message does not provide any detail.
推荐答案
我测试了您的代码，它对我而言很好用.
I tested your code and it works fine on my side.
运行Login-AzureRmAccount在Get-AzureRmSubscription –SubscriptionName Production | Select-AzureRmSubscription之前登录，请验证当前租户中是否存在预订生产.并仔细检查SQL Server的用户名，密码，StorageAccount，StorageAccountKey，ContainerName是否正确.
Run Login-AzureRmAccount to login before Get-AzureRmSubscription –SubscriptionName "Production" | Select-AzureRmSubscription, verify that the subscription Production exists in current tenant. And double check the username,password for SQL server, StorageAccount,StorageAccountKey,ContainerName are all correct.
