}
$count++;
}
echo $message;
I don't know which table to be updated. What needs to change in this code to work update category_ids.

Unless you have a specific reason for using a custom script, you can always use the normal System -> Import/Export -> Dataflow: Profiles -> Import All Products using the file you described.
If you are truly looking for a script I can amend my answer for you.
