Query SQL and output to text file then loop through list to execute

Question

It seems there's no obvious way to do what I want to below as everyone has their own take on querying SQL server with Powershell!
I need to use PowerShell to connect to ServerA and query a test database and select Name from it.  The Name results of that query need to output to C:\names.txt and then I need a ForEach loop to go through that file line by line and execute some text
against each Name from the list.
Any ideas how I can achieve this?
Thanks!

I can't even output SQl to a table at the moment, the text file has a column header and about 50 empty rows in the file.
$dataSource = "DEMO"
$database = "TESTDB"
$connectionString = "Server=$dataSource;uid=$user; pwd=$pwd;Database=$database;Integrated Security=True;"
$query = "SELECT name FROM dbo.names"
$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)
$format = @{Expression={$_.Id};Label="Name";width=25}
$table | format-table $format | Out-File C:\export\servers.txt
$connection.Close()
