Duplicate query across 4 fields.

[Nogger-01]

Hi

I have been trying to create a query that will find the duplicates accross
and number of fields to bring back the values that need checking for example.

I have a table with the following fields

Journey numbers, Revenue Numbers, Board Numbers, and duty numbers.

i need help with a query that will bring back the matching values in the
journey numbers and revenue numbers field. then were once the journey number
and revenue nuimber match the board number doesnt match.

Sorry new to all this.

Thanks.

Have you tried using the query wizard? It has an option to create a Find
Duplicates query and will allow you to define duplicates using multiple fields.
