if you write a select statement to show the data, making sure it works and showing the fields you want appended. then add a line before the select line like so:
insert into #table name# (
and list all the field names you want the data to go to, in the order they are shown in the select statement, before closing the bracket.
if all the fields you are appending are all the fields in the table (ie a table with 5 columns, and you want to append into all 5 columns) simply type
insert into #table name# before the select. hope this helps
