    Latest Date Criteria

    Hello I'm new to the forum and Access.

    I extract Data from a Data feed that is not dated.



    Through an Append Query I add an appropriate date and build a "dated' Database.

    I am having trouble extracting the most recent set of records from that Database using various Criteria.

    Would appreciate suggested criteria.\ to use

    The answer might be really obvious, but not currently for me.

    Thanks in Advance

    Thanks June for the quick response.

    Looks like I need to advance my Access skills to follow the attachment. I mistakenly though that querying for the Latest Date would be pimplier than that

    Query for the lastest (maximum) data is simple. Returning the record that goes with that date is more complicated.

    depending on what exactly you are trying to achieve, there are a number of ways of going about this.

    1. if you want records associated with the latest date:
    a. run an AGGREGATE query to ask for the maximum date: Max(datefield)
    b. once you know the maximum date, run a second query extracting records with that date.

    2. if you want all records dated in the last n days
    a. the criteria, in the date field, will be: [datefield]>=Date()-n


    good luck with your project,
