Update "mysql_fetch_array" to "$wpdb->get_results" in wordpress plugin

Question

I'm updating some old wordpress plugin files and understand I need to update "mysql_fetch_array" to "$wpdb->get_results" to get the plugin to talk with the database.

Here is the code where "mysql_fetch_array" is used:

//select ads id's  stored into db table
$sql  = "SELECT id FROM $table_name_ad_google";
$result = mysql_query($sql);

while($row = mysql_fetch_array($result))
{

How do I rewrite this to use $wpdb->get_results?

version_string = version_string.split(':',1)[1:]
