    Unanswered: Duplicates

    Does anyone know how to find duplicates on a table?

    I have a table with 55383 rows and I queried it with another table that has a matching column and I got back 55384 rows. I assume there is a duplicate.

    access has a find duplicates wizard, I have never used it though, but I presume it works...

    You have tables A (with 50000+ rows) and table B (with presumably far fewer rows). You are joining A to B on columns F2, F3, and F4:

    In the SQL view of query design:

    select F2, F3, F4
    from B
    group by F2, F3, F4
    having count(*)>1
