Access Query - Query to display only first duplicate record and all non-duplicates
I have a database (Access 2000) of Bird sightings, and am trying to create a Query that can produce 'year lists', by showing all the individual species of birds seen in a specific year.
As I may have seen a particular species more than once in a year, it may appear mulltiple times if I simply search by Date.
How can I create a query that will display ALL records for a year, but where there is a Duplication i.e. 2x Crow, only dispaly the FIRST instance of this record. I have tried the 'Group' function, but this does not work.
I don't want to delete the duplicate's as they are all valid for the database, but not for the 'Year List'.
The Duplicates wizard only trells me where the duplicates are.
The Fields of interest are
Species Name - Date - Location - Grid_Ref - Abundance
