Access Queries: How to Create a Parameter Query. Microsoft access 2013 query parameters free
This field will have the same name as the multivalued field, with the string. Value appended. Drag the multivalued field and its single value field to separate columns in the design grid. If you want to see only the complete multivalue field in your results, clear the Show check box for the single value field.
Type your criteria in the Criteria row for the single value field, using criteria that is appropriate for whatever type of data the values represent. Each value in the multivalued field will be individually evaluated using the criteria you supply. For example, you may have a multivalued field that stores a list of numbers.

Resolved my issue. Clear instructions. Easy to follow. For example, if you have a database for a store that sells food items and you want to review orders for customers who live in a particular city.
Say that the data about orders and data about customers are stored in two tables named Customers and Orders respectively. If each table has a Customer ID field, which forms the basis of a one-to-many relationship between the two tables. You can create a query that returns orders for customers in a particular city, for example, Las Vegas, by using the following procedure:.
Open the database. On the Create tab, in the Query group, click Query Design. On the Tables tab, double-click Customers and Orders. This line shows the relationship between the two tables. In the Customers table, double-click Company and City to add these fields to the query design grid. In the query design grid, in the City column, clear the check box in the Show row.
In the Criteria row of the City column, type Las Vegas. Clearing the Show check box prevents the query from displaying the city in its results, and typing Las Vegas in the Criteria row specifies that you want to see only records where the value of the City field is Las Vegas. In this case, the query returns only the customers that are located in Las Vegas. In the Orders table, double-click Order ID and Order Date to add these fields to the next two columns of the query design grid.
On the Design tab, in the Results group, click Run. The query runs, and then displays a list of orders for customers in Las Vegas. If you frequently want to run variations of a particular query, consider using a parameter query. When you run a parameter query, the query prompts you for field values, and then uses the values that you supply to create criteria for your query. Note: You cannot create a parameter query in an Access web app.
Continuing from the previous example where you learnt to create a select query that returns orders for customers located in Las Vegas, you can modify the select query to prompt you to specify the city each time that you run the query. To follow along, open the database that you created in the previous example:. In the Navigation Pane, right-click the query named Orders by City that you created in the previous section , and then click Design View on the shortcut menu.
In the query design grid, in the Criteria row of the City column, delete Las Vegas , and then type [For what city? The string [For what city? The square brackets indicate that you want the query to ask for input, and the text in this case, For what city?
Note: Neither a period. Select the check box in the Show row of the City column, so that the query results will display the city. The query prompts you to enter a value for City. What if you don't know what values you can specify? You can set the parameter to accept only a certain type of data. Note: If a parameter is configured to accept text data, any input is interpreted as text, and no error message is displayed. In the Query Parameters box, in the Parameter column, enter the prompt for each parameter you want to specify a data type for.
Make sure that each parameter matches the prompt that you used in the Criteria row of the query design grid. If a WHERE clause already exists, check to see whether the fields you want to add parameters to are already in the clause. Note that you need to add the same filter to each section of the query. In the picture above, the query has two sections separated by the UNION keyword , so the parameter needs to be added twice.
When you run the query, however, the prompt only appears once assuming you have spelled the prompt exactly the same in each section. For more information about union queries, see Use a union query to view a unified result from multiple queries. Use the Find and Replace dialog box to change data.
