Question

我正在尝试通过Powershell脚本使用主机名和SID值连接到数据库。

我的代码：

$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

我遇到以下错误：

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

ClientConnectionId:00000000-0000-0000-0000-000000000000
Error Number:123,State:0,Class:20

我还尝试将$DataSource的值保持为：

$DataSource ='(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(Host=hostname)(Port=0000)))(CONNECT_DATA=(SID=abc)))'

有人能帮我问问我的脚本是什么问题。

预先感谢

使用Oracle数据库连接。进行了相应的更改，并且有效，使用Oracleclient条目代替了SQLClient。

 $OracleConnection = New-Object System.Data.OracleClient.OracleConnection

使用Powershell脚本连接到Oracle数据库。连接时出错
