Max(date) query: what's most efficient design/approach

Asked by deedub84 in Microsoft Access Database

Tags: MS Access 2003

I have a table of test dates and scores as follows:

EmpID
TestType
TestDate
TestScore
Subject

There are 3 types of tests that employees need to take yearly, potential in 2 or 3 subjects.

I need a query that will show:

EmpID, Subject, TypeA: latest test date, TypeA: latest test score, TypeB: latest test date, TypeB: latest test score, TypeC: latest test date, TypeC: latest test score

But am having trouble getting the max bit to work.  I've considered subqueries and also just iif statements, but can't get it working.

Thanks for the help.
