I have an array (that comes from SQL) and can potentially have one or more rows.

I want to be able to figure out if the array has just one row.

Answer 1

For a 2D array (or more dimensions), use this function:

Function is2d(a As Variant) As Boolean
    Dim l As Long
    On Error Resume Next
    l = LBound(a, 2)
    is2d = Err = 0
End Function

which gives :

Sub test()
    Dim d1(2) As Integer, d2(2, 2) As Integer,d3(2, 2, 2) As Integer
    Dim b1, b2, b3 As Boolean

    b1 = is2d(d1) ' False
    b2 = is2d(d2) ' True
    b3 = is2d(d3) ' True

    Stop
End Sub
