Question

How to count records in a recordset using VBA

Asked by: TimBurraston

Hi,
I have an Access 2007 form that displays a single record from a table that has a number of subordinate tables.  I want to display the number of associated records from each of these tables on the form to alert the user to their presence.  Although familiatr with Excel VBA I can't figure out how to get this working.  I have searched this forum and it looks like there is a "recordset" object that has a "count" property but that's as far as I've got.

Many thanks.

There are several ways to get a record count of a table.

IF ... your tables are local and not linked (?) ... then the simplest and fastest way is:

CurrentDb.TableDefs("YourTableName").RecordCount

So, maybe:

Dim lCnt as Long
lCnt= CurrentDb.TableDefs("YourTableName").RecordCount
Me.SomeTextBoxNameForDisplay = lCnt

or just

Me.SomeTextBoxNameForDisplay = CurrentDb.TableDefs("YourTableName").RecordCount

Lets start with this and go from here ...

IF ... you need to use a 'recordset' object ... then:

Dim rst as DAO.Recordset
Set rst = CurrentDb.OpenRecordset("SomeTableName", dbOpenDynaset)
With rst
    If .Recordcount = 0 Then   ' test for zero records FIRST
       ' no records
    Else
       .MoveLast   ' Move to the end of the record set to get the correct count
       MsgBox "There are " & .RecordCount & " records in the table"
    End If
    .Close
End With

Set rst = Nothing

why would you show a count...and not show the associated records in say..a subform?

How does the user get to the associated records today?

Well, I have several subordinate tables containing related data and would need one subform per table.  As this would be far to much data on one form I simply want to show the number of related records present in each table as a count with a button to allow the user to open a secondary form.

Interesting, however you could introduce a tab control and on each tab place a subform. The records would still be related via the Master/Child properties between the subforms and the main form, the tab control will allow you to "hide" all but the top tab so the form doesn't look so busy, and your data is still available to your user and integrity will be enforced by the form relationships. Just a thought.

Jeff, that's a great idea, thanks.  I'll give that a try but it certainly sounds like the best solution.

Cheers
