[ILUG] yet another sql (access) question

I have a table. It has a number of fields. One if these fields is called
'ProjectName'. It is a String. Another one is called 'Date'. It is a Date.
What I want to do is to not allow duplicate entries in the table for these two
fields. An example to clarify:
(can't have two entries of 'Project1' with the date 5/5/2001)
I am using access. Is there a way of doing this without actually looking for a
previous entry with the same project name and date before adding a new entry
to the table?
