Filter a Report based on user input Microsoft Access

问题

My apologies if this is an easy/straightforward solution, but I am new to Access, and I have been having some problems with my reports.

I have created a report template which I want to open a single page report based on a specific IDENT NO. All of the fields in the report are then generated from the associated IDENT NO. As it currently stands, when I open the report, it will create a single page report for each ID number in the Report Data table when opened.

Instead, when the user is attempting to open the report, I want it to prompt the user to enter the identification number of the specific report they are looking for so that it only opens that single individual 1 page report associated with the entered IDENT NO.

Any Ideas on how I could achieve this filtering?

回答1:

You can display an InputBox for the user to insert the ID and then open and filter the report.

Dim id As String
    id = InputBox("Enter the identification number:", "YourInputBoxTitle")

'if a value was entered, open and filter report
If Len(Trim(id)) > 0 Then
    DoCmd.OpenReport "ReportName", acViewPreview, , "[IDENT NO] = " & id, acWindowNormal
End If

回答2:

An alternative to using InputBox is to used a "parameter query" (documentation here)

Anywhere in a query criteria or report design view you may enter [IdentNoVariable] and a dialog box will appear (when the report or query is run) asking you to "Enter Parameter Value" for IdentNoVariable.

For example, if you wanted to restrict an ID # during a query (say the query that your report calls):

The dialog box seen appeared upon running the query and has the text of the variable seen in the query criteria. This same thing can be done in a report by entering [IdentNoVariable] into the part of the report where the entered value is desired.
