![]() ![]() ![]() Return items that don’t match the parameter ![]() For example, the parameter string us returns items where the parameter field has a value of Australia and items where the value is USA.įor more information about wildcards, see Using Wildcard characters as criteria. 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:Īfter you enter the parameter, the query returns values that contain the parameter string. In the Criteria row of the field you want to add a parameter to, type Like "*"&"*". For example, you might want your query to prompt for a country/region of origin, but to match any value that contains the parameter string. Combine parameters with wildcards for more flexibilityĪs with normal criteria, you can combine parameters with the Like keyword and wildcard characters to match a wider range of items. When you run the query, however, the prompt only appears once (assuming you have spelled the prompt exactly the same in each section).įor more information about union queries, see Use a union query to view a unified result from multiple queries. In the picture above, the query has two sections (separated by the UNION keyword), so the parameter needs to be added twice. Note that you need to add the same filter to each section of the query. Type your parameter prompt into the where clause, for example, WHERE = If a WHERE clause already exists, check to see whether the fields you want to add parameters to are already in the clause. Since you can’t view a union query in the query design grid, you’ll need to do things a little differently:Īdd a WHERE clause that contains the fields you want to add parameters to. In the Data Type column, select the data type for each parameter. Make sure that each parameter matches the prompt that you used in the Criteria row of the query design grid. In the Query Parameters box, in the Parameter column, enter the prompt for each parameter you want to specify a data type for. With the query open in Design view, on the Design tab, in the Show/Hide group, click Parameters. To specify the data type for parameters in a query: ![]() Note: If a parameter is configured to accept text data, any input is interpreted as text, and no error message is displayed. It is especially important to specify the data type for numeric, currency, or date/time data, because then, people will see a more helpful error message if they enter the wrong type of data, such as entering text when a currency value is expected. You can set the parameter to accept only a certain type of data. For example, Between And will generate two prompts when you run the query. You can use multiple parameters in a criterion. When you run the query, the prompt appears without the square brackets.įill in the value you’re looking for, and then click OK. Repeat step 2 for each field you want to add parameters to. 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. Create a parameter queryĬreating a parameter is similar to adding a normal criterion to a query:Ĭreate a select query, and then open the query in Design view. You can add parameters to any of the following types of queries:Ĭriteria Criteria are the “filters” you add to a query to specify which items are returned when you run the query.įor more information about the types of queries mentioned above, see Introduction to queries. Parameters can be used by themselves or as part of a larger expression to form a criterion in the query. Parameter A parameter is a piece of information you supply to a query right as you run it. Understanding the terminologyīefore getting into the step-by-step below, it’s helpful to understand these terms: Note: This article doesn't apply to Access web apps. ![]()
