Creating seperate txt files for each row retrieved from SQL statement

Hello

This is my first post. I am pretty new to Powershell and wondered if anybody can help!. I have this code which needs to write each row from the SQL query to a serperate txt file. The problem I have is that the first result is created fine but the remaing results get grouped together and put into another file which is not what I want. I believe it is to do with the loop.

Any help Please

Thanks

$Username = "hsw_pcc";
$Password = "hsw_pcc";
#$file = "F:\Mark.txt";    # Sets the location for the file to write to

$Connection = New-Object Data.SqlClient.SqlConnection

$Connection.ConnectionString = "Data Source=test2k801\t2k801;Initial Catalog=SWData;Persist Security Info=True;User ID=$Username ;Password=$Password"

$Connection.Open()

$sql =   "select  callref, prob_text
Problem from opencall
where suppgroup = '3RDLINE/APPSUPPORT/'
and (closedby IS NULL OR closedby =
'')
 and callclass ='Incident' and owner =  ''
    order by callref"

$Command = New-Object System.Data.SqlClient.SqlCommand $sql,$Connection

$Reader = $Command.ExecuteReader()

$counter = $Reader.FieldCount
 
while($Reader.read())

  {  # open of the while loop

   $file =  "F:\Testing"+$i+".txt"

echo $counter    
    for($i = 0; $i -lt $counter; $i++)
  {
   @{ $Reader.GetName($i) = $Reader.GetValue($i);}
   $reader[$i] >> $file

  } # close of the for
  } # close of the while

       
$Connection.Close()
