Invoke SQL commands from Powershell script

  • Article

Hi everyone, 

I've been trying to find a good script to invoke SQL commands without installing the SQLPS module but without success.

So I managed to create one:

function InvokeSQL{
    param([string] $DataSource, $Database,$Username, $Password, $Query)

    $connectionString = “Server=$DataSource;uid=$Username; pwd=$Password;Database=$Database;Integrated Security=False;”
    $connection = New-Object System.Data.SqlClient.SqlConnection
    $connection.ConnectionString = $connectionString

    $connection.Open()
        $command = $connection.CreateCommand()
        $command.CommandText = $query
        $result = $command.ExecuteReader()
        $table = new-object “System.Data.DataTable”
        $table.Load($result)
        $table
    $connection.Close()
}

Hope someone finds this helpful.
