使用 PowerShell 对 Azure SQL 数据库运行 SQL 查询

Question

我的任务是从我们的 Azure SQL 数据库中检索用户列表。我们有 100 多个 Azure SQL 数据库，我想使用 PowerShell 来快速完成任务。

我正在使用连接字符串（Active Directory 集成）。我相信我能够使用 PowerShell 的连接字符串登录到 SQL 数据库。

但是，我在运行 SQL 时遇到错误。下面是代码和异常。你能帮帮我吗？

代码：

try {
    $new = 'Server=tcp:dummy.database.windows.net,1433;Authentication="Active Directory Integrated";Initial Catalog=xtoiteuitbdbsqldb01;Persist Security Info=False;MultipleActiveResultSets=False;Encrypt=True;TrustServerCertificate=False;'
    $sql = "SELECT * FROM sys.database_principals"
  $temp_result_object = invoke-sqlcmd -ConnectionString $new -Query $sql
} catch {
  "error when running sql $sql"
  write-host "Exception type: $($_.Exception.GetType().FullName)" -ForegroundColor Red
    write-host "Exception message: $($_.Exception.Message)" -ForegroundColor Red
    write-host "Error: " $_.Exception -ForegroundColor Red   
}

例外：

异常类型：ManagedBatchParser.ParserException
异常消息：
错误：ManagedBatchParser.ParserException

在 ManagedBatchParser.Parser.Parse()
在 Microsoft.SqlServer.Management.PowerShell.ExecutionProcessor.ExecuteTSql(String sqlCommand)

Answer 1

您可以使用 .NET SqlClient 提供程序来使用密码或“Active Directory 集成”身份验证，例如：

# connect to database
$dbConn = New-Object System.Data.SqlClient.SqlConnection
$dbConn.ConnectionString = "Server=tcp:dummy.database.windows.net,1433;Database=DummyDB;Authentication=Active Directory Integrated;Encrypt=True;"
$dbConn.Open()

# construct command
$dbCmd = New-Object System.Data.SqlClient.SqlCommand
$dbCmd.Connection = $dbConn
$dbCmd.CommandText = "SELECT * FROM sys.database_principals"

# fetch all results
$dataset = New-Object System.Data.DataSet
$adapter = New-Object System.Data.SqlClient.SqlDataAdapter
$adapter.SelectCommand = $dbCmd
$adapter.Fill($dataset)

# display results
$dataset.Tables | Format-Table

Answer 2

以下对我有用，Connect-AzAccount 通过浏览器触发交互式 AAD 身份验证

Example 11: Connect to Azure SQL Database (or Managed Instance) using an Access Token

Import-Module SQLServer
Import-Module Az.Accounts -MinimumVersion 2.2.0

# Note: the sample assumes that you or your DBA configured the server to accept connections using
#       that Service Principal and has granted it access to the database (in this example at least
#       the SELECT permission).

### Obtain the Access Token: this will bring up the login dialog
Connect-AzAccount
$access_token = (Get-AzAccessToken -ResourceUrl https://database.windows.net).Token

# Now that we have the token, we use it to connect to the database 'mydb' on server 'myserver'
Invoke-Sqlcmd -ServerInstance myserver.database.windows.net -Database mydb -AccessToken $access_token`
              -query 'select * from Table1'

Answer 3

试试下面的方法，看看是否有帮助：

$Svr = "SVR"
$SvrPort = 10003
$Username = "ABC\sql"
$Password = "ABC#@!"

$Password = $Password | ConvertTo-SecureString -AsPlainText -Force
$Cred = New-Object System.Management.Automation.PSCredential -ArgumentList $Username,$Password
$Inst = $Svr + "," + $SvrPort

Get-PSSession

New-PSSession -ComputerName $Svr -Credential $Cred

Invoke-Sqlcmd -ServerInstance $Inst -Database "master" -Query "SELECT @@SERVERNAME AS SERVER_NAME"

Get-PSSession

Get-PSSession | Remove-PSSession

Invoke-Sqlcmd -ServerInstance $Inst -Database "master" -Query "SELECT @@SERVERNAME AS SERVER_NAME"

Get-PSSession
