Hi,
So new to this I could pull my hair out. So go easy on me. Thank you for any
help you can offer.
I have 1 query that is pulling from 3 tables. In those tables there aren't
any duplicate entry's yet in the query i get duplicates for some entries. I
can find no correlation as to why it could be choosing these as duplicates.
Any direction?

Thank you,

Jennifer

Hi Jennifer,

What you have asked is akin to saying: "My car is making a funny noise, but
it shouldn't". Details, details, details.. :)

There might be a couple of MVPs that are psychic, but the majority of us
(non MVPs)are not. It would be helpful (to start off with) to post the SQL of
your query since we cannot see your database.

As a guess there are multiple records in one table that match up to records in
another table.

Simple example
TableOne has only two records with Values in fieldOne of 1 and 2
TableTwo has four records with values in field2 of 1,1,1 and 2
If you run a query with TableOne joined to TableTwo on FieldOne To Field2, you
will get four records returned
3 records for TableOne.FieldOne where the value of field one = 1
1 record for TableOne.FieldOne where the value of FieldOne =2

You have what is known as a Cartesian effect. This happens when your tables
are not properly joined. The quanity of records in one is multipled by the
number of records in the other.

Post the SQL of your query for suggestions on how to fix.

So I am sorry to say I don't have a clue how to find the SQL of my query. I
can look at my query in design view but how to look in SQL?

I am so used to Excel all the Access language has me pulling my hair out.
