I have a table with Employees, and the month and year they started. I need to number them in order of the month and year they started. Example: July 2001 is employee 1 and August 2001 is employee 2. However there may be multiple employees in a given month and year. It seems like this should be a simple task but I can not figure it out. I have a query that puts them in the right order but not sure how to update the ID with the correct number. I'm using Microsoft Access 2002.
