Я пытаюсь подключиться к базе данных, используя значения Hostname и SID через сценарий PowerShell.
Мой код:
$DataSource ='HOSTNAME:PORT/INSTANCE'
$Username='Username'
$Password='Password'
#List
$UserDataDT = New-Object System.Data.DataTable
$SQLConnection = New-Object System.Data.SqlClient.SqlConnection
$SQLConnection.ConnectionString = "Data Source=$DataSource;User Id=$Username;Password=$Password;"
$SQLCmd= New-Object System.Data.SqlClient.SqlCommand
$SQLConnection.open();
$SQLCmd.Connection = $SQLConnection
$SqlCmd.CommandTimeout = 600
Я получаю следующую ошибку:
catch Exception...
System.Data.SqlClient.SqlException (0x80131904): A network-related or instance-specific error occurred while establish
ing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is corre

Я также пытался сохранить значение $DataSource как:
$DataSource ='(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(Host=hostname)(Port=0000)))(CONNECT_DATA=(SID=abc)))'
Может ли кто-нибудь помочь мне, в чем проблема с моим scirpt.
Заранее спасибо
