Creating a Parameter Query

Learn how to run an Access parameter query to find the data you need using variable criteria in your search terms.

Introduction

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. This way, each time we run the query a dialog box will appear prompting us to enter the date we’d like our query to search for.

A prompt in a parameter query

We’ll enter the date we want, then Access will run the query using the date we entered as a search term.

To create and run a parameter query:

  1. Create a query as you normally would, modifying the table joins if necessary, selecting the fields to include in your query, and adding any nonvariable criteria to the appropriate fields in the Criteria: row.
  2. Locate the field or fields where you want the variable criteria to appear, then select the Criteria: row.
  3. Type the phrase you want to appear in the prompt that will pop up each time you run your query. Make sure to enclose the phrase in brackets [ ]. For example, in our parameter query that searches for orders placed on a certain date, we might type our criteria like this: [What Date?].
  4. On the Design tab, click the Run command to run your query. A dialog box will appear with the specified prompt. Enter your search term and click OK to view your query results.

You can simply open an existing parameter query to run it.
