are 35 rows to add and a common field 'FabID'. My surprise is that
instead of adding the values in the rows from 1 to 35, it starts in the
row number 36. It seems like you only could use INSERT INTO...SELECT
when you want to add fields to a new table with no values
added yet. I don't know how to write the sentence in the way I need.
