Question : Utilizing array gleamed from GetRows method in Access VBA

Hi. I am using the code below to gather the IDs of the fields where the field 'Invoiced" is checked.
This creates a two dimensional array. I need to use each of the values held in this array but am not sure how. For instance if I use MsgBox UBound(MyID) when there are three values I get 1 returned which doesn't make sense

    Dim db As Database
    Dim rs As dao.Recordset
    Dim MyIds As Variant
 
    Set db = CurrentDb
    Set rs = db.OpenRecordset("Select ID from [Room Bookings] where Invoiced = true")
    'You might try .MoveLast and .MoveFirst to insure the recordset is filled whe using the GetRows method below
    rs.MoveLast
    rs.MoveFirst
    '/note I also use an arbitrarily large number instead of .Recordcount
    MyIds = rs.GetRows(999999)
    rs.Close
    Set rs = Nothing
    Set db = Nothing

Answer : Utilizing array gleamed from GetRows method in Access VBA

It is a 2d array (0,0) - (0, recordcount-1)

So

MsgBox UBound(MyIds, 2)

Will tell you the ubound of the 2nd dimension.
