[AccessD] Duplicates Query

Hi Rocky

I believe you will have to group by these fields in a way to build a unique string, say:

  Group By [Field1] & "-" & [Field2] & "-" & [Field3]

Gustav:

There are actually three fields that have to match up to make a duplicate.
I suppose I could add another field which is the concatenation of those
three but that seems kludgey.  Any other more elegant solution?

TIA

Rocky

Hi Rocky

Use First or Last or Max or Min - just one that will return only one PK of
the records where the field named "name" holds identical values.

 Gustav:

Looks right but it has step 2 as:

2. Create a totals Query1 which shows GroupBy the name, and First of the PK.

I assume totals query = summation query.  But "GroupBy the name" - what does
'name' refer to?  And how to do First of the PK?

TIA

Hi Rocky

Yes. Look up a not so old thread:

Dear List:

I used the find duplicates query wizard to make a query to find duplicate
records in a table.  Is there a quick way to then delete all but one
occurrence of the duplicated records?
