Pass a parameter into an access report programmatically

Question

I\'ve got an existing Access MDB. I\'m adding a command button to an existing Form that runs an existing report. The change being made is that this button needs to pass in

Answer 1

My general approach to this type of problem is to save the criteria in the database, typically a control table that has one row. Then to reference your criteria you put a query in paranthesis that returns one value, of the criteria you want. In your case, it would be something like:

(select reportID from control)

The advantage of this techinque is that the control table remembers the settings for the next time you run the report. Of course, ReportID would be tied to a field in a form. I also like the fact that your queries are isolated from forms; they can be run independently of forms.

Answer 2

I know this is an old post but this took me a bit. Error was "Invalid use of parren" however the issue was the space in the field name. I was creating a report from a db that someone did the common mistake, spaces.

To pass a param to a query through the where clause when the database field has a space use this example:

DoCmd.OpenReport "rptByRegionalOffice", acViewPreview, , "[" & "Regional Office" & "]" & "=" & "'" & cmboOffices.Value & "'"

If you think about this you can see that this will produce where [Regional Office]='string value' just as you would expect in access sql.

Answer 3

The DoCmd.OpenReport method has various arguments, one of which is a Where statement:

DoCmd.OpenReport"rptReport", acViewPreview,,"ID=" & Me.ID

That is

expression.OpenReport(ReportName, View, FilterName, WhereCondition, WindowMode, OpenArgs)

Answer 4

Why everyone wants to make this so complicated, I don't know.

1. save your report's recordsource without parameters.

2. as suggested by Remou, pass the criteria in the appropriate argument of DoCmd.OpenReport.

Trying to do it any other way is going to be a matter of resisting the natural methods for accomplishing tasks in Access.

Answer 5

The Where clause of the docmd.openreport is a string that uses the same format as the where clause in a SQL statement.

The reason to put parameterize you query at the docmd instead of the RecordSource of the report is flexibility. You may have a need to open the report without any paremeter/return all the records or have the ability to filter on different fields.
