A parameter query is one of the simplest and most useful queries you can create. Because parameter queries are so simple, they can be easily updated to reflect a new search term. When you open a parameter query, Access will prompt you for a search term and show you query results that reflect your search.
When you’re running parameter queries, search terms act as variable criteria, which are query criteria that change each time you run the query. For instance, let’s say we own a bakery and want to create a query that will quickly look up orders that were placed on a certain date. We could create a parameter query with variable criteria in the Date field.
