Use wildcards in queries and parameters in Access.
Find links to more information about how to create parameter queries in the See Also section. Top of Page. If the Enter Parameter Value dialog box appears when you open a report, follow these steps to inspect the report's properties: Right-click the report in the Navigation Pane, and then click Design View.
Right-click the form in the Navigation Pane, and then select Design View. If the Property Sheet task pane isn't displayed, press F4 to display it. Inspect expressions in a combo box or list box on the form.
Use this procedure to inspect the Row Source property of the control: Right-click the form in the Navigation Pane, and then select Design View. Click the combo box or list box that you want to inspect. Right-click the table in the Navigation Pane, and then select Design View. Need more help? Expand your skills. Get new features first.

Resolved my issue. Clear instructions. Easy to follow. No jargon. Pictures helped. Didn't match my screen. Incorrect instructions. Too technical. Not enough information. Not enough pictures. Here, you will see where and how you add the criteria. To add a criteria to a query, you must open the query in Design view. You then identify the fields for which you want to specify criteria. If the field is not already in the design grid, you add it by either dragging it from the query design window to the field grid, or by double-clicking the field Double-clicking the field automatically adds it to the next empty column in the field grid.
Finally, you type the criteria in the Criteria row. Criteria that you specify for different fields in the Criteria row are combined by using the AND operator. In other words, the criteria specified in the City and BirthDate fields are interpreted like this:. What if you want only one of these conditions to be met? In other words, if you have alternate criteria, how do you enter them?
If you have alternate criteria, or two sets of independent criteria where it is sufficient to satisfy one set, you use both the Criteria and the or rows in the design grid.
Criteria specified in the Criteria and or rows are combined using the OR operator, as shown below:. If the criteria is temporary or changes often, you can filter the query result instead of frequently modifying the query criteria. A filter is a temporary criterion that changes the query result without altering the design of the query. For more information about filters, see the article Apply a filter to view select records in an Access database.
If the criteria fields don't change, but the values you are interested in do change frequently, you can create a parameter query. A parameter query prompts the user for field values, and then uses those values to create the query criteria. For more information about parameter queries, see the article Use parameters in queries and reports. The following examples are for the CountryRegion field in a query that is based on a table that stores contacts information. The criterion is specified in the Criteria row of the field in the design grid.
A criterion that you specify for a Hyperlink field is, by default, applied to the display text portion of the field value. The syntax for this expression is as follows: HyperlinkPart [Table1]. Query result. For a list of such characters, see the article Access wildcard character reference. Returns records where the field is set to a blank but not null value. For example, records of sales made to another department might contain a blank value in the CountryRegion field.
Returns records where there is either no value in the field, or the field is set to a blank value. Note: The characters? The following examples are for the UnitPrice field in a query that is based on a table that stores products information. The criterion is specified in the Criteria row of the field in the query design grid.
Use this crit erion. The following examples are for the OrderDate field in a query based on a table that stores Orders information. Returns records of transactions that took place on Feb 2, Remember to surround date values with the character so that Access can distinguish between date values and text strings.
You can also use the Between operator to filter for a range of values, including the end points. Returns records where the transactions took place on Feb 1, , March 1, , or April 1, Contain a date that falls in a specific quarter irrespective of year , such as the first quarter. Returns records of transactions that took place on the current day. Returns records of transactions that took place the day before the current day.
Returns records of transactions that took place the day after the current day. Returns records of transactions that took place during the current week. A week starts on Sunday and ends on Saturday.
Returns records of transactions that took place during the last week. Returns records of transactions that will take place next week. Returns records of transactions that took place during the last 7 days. Returns records for the current month. Returns records for the previous month. Choose a format that reflects the data type of the parameter field. For example, select General Date for a date field.
Using the submacro features of Access macros we can define all the needed steps we need to make in a single macro. Using the screenshot below as a guide, create a new macro with the following submacros and actions. Note, for this example, our parameter form is called frmCriteria.
Adjust your macro to match the name of the form you created earlier. You'll also need to be sure to click Show All Actions on the Design tab in order to view all macro actions. Save and close the macro. Give the macro a name, for example, Date Range Macro. On the Design tab, in the Controls group, click Button. Position the pointer below the text boxes on your form, and then drag to create an OK command button.
Create a Cancel command button and set its properties, as shown in the following table. Enter the criteria for the data. Use the Forms object, the name of the form, and the name of the control:. For example, in an Access database. Between [Forms]! Make sure the Record Source property of the report is using the parameter query you defined earlier.
Enter the name of the macro, for example, Date Range Macro. Open Dialog. Close Dialog. Similarly, when you close the report, Access will run the actions defined in the Close Dialog submacro of the Date Range Macro object.
Now that you're created all of the Access objects, it's time to try it out. Open your report in Report View or Print Preview and notice that before Access displays the report, your parameter form opens in dialog mode. Enter the criteria needed into the text boxes you created previously and then click the OK command button on the form. This works because the parameter query that the report is based on can read the values in the controls on the hidden form.
When you close the report, Access will also close the parameter form. Need more help? Expand your skills. Get new features first. Was this information helpful?
