ms access query - find unmatched

Posted on 2014-01-20

I have 2 linked .dbf tables that I want to check for unmatched entries on 2 fields. Field#1 is a text field in both tables. field#2 is a text field in table#1 which contains a date in the format yyyymmdd. field#2 is a date field in table#2 in the format mm/dd/yyyy.

I need a query that will detect an unmatched entry based on the 2 fields. Don't know how to specify/convert field#2 in table#1 so that I don't get a "type mismatch" error on the 2 date fields.

Source tables cannot be changed.

part 1: converting text vs date values:
Cdate(field2)   for the text field
or
Format( field, "mm/dd/yyyy")  for the date field

part 2: non-matched entries - you can do with the wizard:

are you working in a SQL Query Window, or pure sql?
the table names remain as they are, instead of the field name, you put the expression having the function(fieldname) instead of just fieldname
