    Hi all,
    I have two table both with the same Unique Identifier field (staffID) I need
    to construct a sql statement that lists the records in the first table as
    long as their staffID does not exist in the second table.
    Example table:

    Table 1.
    StaffID, Firstname, Surname

    Table 2
    StaffID, LoggedIn, Dte


    Can anyone help me out with this?

    cheers,

    nathan.

    Hi Nathan,

    There is a "Find Unmatched Query Wizard" built into Access to assist you
    with this very type of task. Select the Queries tab in the database window.
    Click on the New button. The last item in the list is the wizard that you
    want to use.

    SELECT Table1.StaffID, Firstname, Surname
    FROM Table1 LEFT JOIN Table2 ON Table1.StaffID = Table2.StaffID
    WHERE Table2.StaffID Is Null;
