What is a parameters?

Answer 1

a parameter query is a query that prompts the user to enter specific criteria every time the query is run. When building the query, you would enter the prompt in the criteria line under the field you want the information to be filtered from. For example, if you wanted to look at items that sold on a specific date each time you ran the query, your criteria line would look like this: [enter date of sale] So when you ran the query, before your results even appeared, a parameter box would pop up telling you "enter date of sale", the user would enter the date and then the filtered criteria of the query results will show.
