In the Data Type column, select the data type for each parameter.Īlthough parameter queries feature a built-in dialog box that collects parameters, they provide only basic functionality. Make sure that each parameter matches the prompt that you use in the Criteria row of the query design grid. In the Query Parameters dialog box, in the Parameter column, type the prompt for each parameter for which you want to specify the data type. 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, follow these steps: Note: If a parameter is configured to accept text data, any input is interpreted as text, and no error message is displayed. When you specify the data type that a parameter should accept, users see a more helpful error message if they enter the wrong type of data, such as entering text when currency is expected. You can specify the data type for any parameter, but it is especially important to specify the data type for numeric, currency, or date/time data. You can also specify what type of data a parameter should accept. Instead of using a criterion in the WHERE clause, use a parameter prompt. If a WHERE clause already exists, check to see whether the fields for which you want to use a parameter prompt are already in the clause, and if not, add them. You can also add a parameter to a union query by following these steps:Īdd a WHERE clause that contains each of the fields for which you want to prompt for a parameter.
You can use the preceding steps to add a parameter to any one of the following types of queries: Select, Crosstab, Append, Make-table, or Update. Repeat step 2 for each field that you want to add parameters to. In the second example, two dialog boxes appear: one for Start Date and one for End Date. Note: A separate dialog box appears for each parameter prompt. You can also use an expression with your parameter prompts, for example: When you run the parameter query, the prompt appears in a dialog box without the square brackets. In the Criteria row of a field for which you want a parameter applied, type the text that you want the parameter dialog box to display, enclosed in square brackets, for example: Add a parameter to a queryĬreate a select query, and then open the query in Design view. For each parameter, a parameter query displays a separate dialog box that prompts you for a value for that parameter. 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. Using a parameter in a query is as easy as creating a query that uses criteria.
