I have a query I'm designing which grabs data from multiple different tables. In MS Access 2010, how would I create one of the query columns so that it returns the most recent date out of a series of dates, for each user in the table:
Sample data from table:
userid: | appointment: 000001 | 05/10/2009 000001 | 05/10/2010 000001 | 05/11/2010 000002 | 05/12/2009 000002 | 30/12/2010
expected output for field query:
userid: | appointment: 000001 | 05/11/2010 000002 | 30/12/2010

SELECT B.Job_Emp_ID, B.JobTitle, B.Salary,B.AssignmentDate FROM tbl_Emp_Job_Assignment as B INNER JOIN tbl_Emp_Job_Assignment as A ON (B.Job_Emp_ID=A.Job_Emp_ID and B.AssignmentDate>A.AssignmentDate) GROUP BY B.Job_Emp_ID, B.JobTitle,B.Salary, B.AssignmentDate;
This works Great!It gives the Latest job assignment and Assignment Date.
