can you show the SQL commands you used to add this column and populate
it?   if you used INSERT to populate the new column, that would have
inserted NEW rows, not modified existing rows.  to modify the existing
rows, you need to use UPDATE with a WHERE clause that selects the
correct row to UPDATE with the data for your new field...
