====== 4.2 Daten lesen mit VBA ======

Tabellendaten per REST-API abrufen.

===== Komplettes Beispiel =====

<code vb>
Sub LadeKunden()
    Dim http As Object
    Dim url As String
    Dim json As String

    url = "http://localhost:5000/api/v1/dsn/demo/tables/Customers?$top=10"

    Set http = CreateObject("MSXML2.XMLHTTP")
    http.Open "GET", url, False
    http.setRequestHeader "Accept", "application/json"
    http.send

    If http.Status = 200 Then
        json = http.responseText
        Debug.Print json
    Else
        MsgBox "Fehler: " & http.Status
    End If
End Sub
</code>

===== Mit Filter =====

<code vb>
url = "http://localhost:5000/api/v1/dsn/demo/tables/Customers" & _
      "?$filter=Country eq 'Germany'&$orderby=Name"
</code>

===== URL-Encoding =====

Sonderzeichen im Filter müssen kodiert werden:

<code vb>
filter = Application.EncodeURL("Country eq 'Germany'")
</code>
