Microsoft access 2016 parameter query free download

 

To make a query in Access desktop databases ask for criteria when you run it, create a parameter query. This allows you to use the same query over and over without having to constantly open it in Design view to edit the criteria.

Note: This article doesn’t apply to Access web apps. Parameter A parameter is a piece of information you supply to a query right as you run it. Parameters can be used by themselves or as part of a larger expression to form a criterion in the query.

You can add parameters to any of the following types of queries:. For more information about the types of queries mentioned above, see Introduction to queries. Creating a parameter is similar to adding a normal criterion to a query:.

In the Criteria row of the field you want to apply a parameter to, enter the text that you want to display in the parameter box, enclosed in square brackets. For example, [Enter the start date:]. When you run the query, the prompt appears without the square brackets. You can use multiple parameters in a criterion. For example, Between [Enter the start date:] And [Enter the end date:] will generate two prompts when you run the query.

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. To specify the data type for parameters in a query:. 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. In the Data Type column, select the data type for each parameter. 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. As with normal criteria, you can combine parameters with the Like keyword and wildcard characters to match a wider range of items. To do this:. When you run the parameter query, the prompt appears in the dialog box without the square brackets, and without the Like keyword or wildcard characters:.

After you enter the parameter, the query returns values that contain the parameter string. For example, the parameter string us returns items where the parameter field has a value of Australia and items where the value is USA. For more information about wildcards, see Using Wildcard characters as criteria. For example, you might want to prompt for a year and then return items where the year is greater than the one you entered.

Using a parameter in a query is as easy as creating a query that uses criteria. You can design a query to prompt you for one piece of information, such as a part number, or for more than one piece of information, such as two dates.

For each parameter, a parameter query displays a separate dialog box that prompts you for a value for that parameter. Watch this video to learn more about creating parameters in queries.
