[AccessD] Record count

What about DLookup("MyField", "MyTable")?

Or is that too simple? ;-)

/could also use DCount, but I would imagine that performance would
suffer on big tables.

Try this...

Function bIsTableEmpty(strDataSource As String) As Boolean Dim db As
DAO.Database Dim rs As DAO.Recordset
    Set db = DBEngine(0)(0)
    Set rs = db.OpenRecordset(strDataSource, dbOpenForwardOnly)
    With rs
        On Error Resume Next
        .MoveFirst
        If Err.Number <> 0 Then bIsTableEmpty = True
        On Error GoTo 0
        bIsTableEmpty = .EOF
        .Close
    End With
    Set rs = Nothing
    Set db = Nothing
End Function

If the table / query has no records then the .MoveFirst line will cause
an error. This is trapped to give you the result you want.

What is the easiest way in code to determine if a table has at least one
record? TIA
