Using Criteria to Focus Query Results
It’s likely you won’t want your query to find every record in a table—if you did, you could just open the table and not bother with the query! To limit the records a query locates, such as only finding customers in Germany, you can add criteria to the fields in the Query design grid.
Set Query Criteria
Open a query in Design view.
Click the Criteria cell for the field to which the criterion will be applied.
