You might want to adjust the joins that Access creates. Summarize data This step is optional. This additional functionality includes grouping and aggregating data summarizing, counting, and analyzing data, e.
If Access automatically creates the correct joins when you add the data sources, you can skip ahead to Step 3: Having a basic understanding of the concepts provided in these articles will make the following a bit easier to digest. To use a subquery to define criteria for a field, type a SQL select statement in the Criteria cell.
Select both tables from the Show Table dialog and click Add, then Close. For example, you may have a Lookup field that displays Employee Name, but uses a foreign key that is of the Number data type.
