append query greatly increases number of records

[Guest]

When I make an an append query with same type names number of fields the
number of records increases more than 10 fold. Any ideas?

Thanks

Change it to a select query and see how many records it selects.

I get the same greatly increased number. What does that tell me?

Are there duplicates? I've had this happen when I didn't
join the tables correctly getting 4 or five duplicate rows
where I should have been getting one.

It tells you that the query is not doing what you thought it would (or want
it to do). There are a number of things that can cause that to happen. The
most likely, is that there is a problem with the way the query is built. If
you post the query, perhaps someone here can spot the problem.

Please open the Query and use the View menu option to view it in SQL
view. Post the SQL text here.

I'm guessing that you're creating a Cartesian join by including both
the source table and the target table in the query, with no join
line... it's an easy mistake to make! You don't need the target table
(the table into which you're inserting data) in the query grid.
