Introduction

When working with Microsoft lists and VBA (Visual Basic for Applications) to perform SQL operations, you may encounter issues that prevent you from updating certain fields. In this article, we will explore the common problem of "Field cannot be updated" in VBA SQL and provide a step-by-step guide to troubleshoot and resolve this issue.

Understanding the Problem

The issue you're facing is likely due to the fact that you're trying to update a field that is not allowed to be modified. This can happen for several reasons, including:

Read-only fields: Some fields in a Microsoft list are designated as read-only, meaning they cannot be updated through VBA SQL.
Calculated fields: Fields that are calculated based on other fields or formulas may not be updatable.
System fields: Certain system fields, such as the created date or modified date, may not be updatable.

Analyzing the Code

Let's take a closer look at the code you provided:

Sub SPListPushData()
Const SiteUrl As String = &quot;https://your-site.sharepoint.com&quot;
Const ListName As String = &quot;Your List Name&quot;
Const FieldName As String = &quot;Your Field Name&quot;

Dim conn As ADODB.Connection
Set conn = New ADODB.Connection

conn.Open &quot;Provider=Microsoft.ACE.OLEDB.12.0;&quot; &amp; _
          &quot;Data Source=&quot; &amp; SiteUrl &amp; &quot;;&quot; &amp; _
          &quot;Extended Properties=&quot;&quot;Excel 12.0 Xml;HDR=YES;IMEX=1&quot;&quot;&quot;

Dim cmd As ADODB.Command
Set cmd = New ADODB.Command

cmd.ActiveConnection = conn
cmd.CommandText = &quot;UPDATE &quot; &amp; ListName &amp; &quot; SET &quot; &amp; FieldName &amp; &quot; = &#39;New Value&#39;&quot;

cmd.Execute

conn.Close
Set conn = Nothing

End Sub

Identifying the Issue

The problem lies in the fact that you're trying to update a field that is not allowed to be modified. To troubleshoot this issue, you need to identify the field that is causing the problem.

Step 1: Check the Field Type

The first step is to check the type of the field you're trying to update. If the field is a read-only field, calculated field, or system field, you won't be able to update it.

Step 2: Verify the Field Name

Make sure the field name you're using in your VBA SQL code is correct. A small typo or incorrect field name can cause the update to fail.

Step 3: Check the List Permissions

Ensure that you have the necessary permissions to update the list. If you're trying to update a field that requires administrative permissions, you may need to run the code as an administrator.

Step 4: Use the SharePoint REST API

If you're still facing issues, consider using the SharePoint REST API to update the field. The REST API provides a more flexible and powerful way to interact with SharePoint lists.

Example Code: Using the SharePoint REST API

Here's an example code snippet that uses the SharePoint REST API to update a field:

Sub SPListPushData()
Const SiteUrl As String = &quot;https://your-site.sharepoint.com&quot;
Const ListName As String = &quot;Your List Name&quot;
Const FieldName As String = &quot;Your Field Name&quot;
Const NewValue As String = &quot;New Value&quot;

Dim xhr As Object
Set xhr = CreateObject(&quot;MSXML2.XMLHTTP&quot;)

xhr.Open &quot;PATCH&quot;, SiteUrl &amp; &quot;/_api/web/lists/GetByTitle(&#39;&quot; &amp; ListName &amp; &quot;&#39;)/items(&quot; &amp; ListItemID &amp; &quot;)&quot;, False

xhr.setRequestHeader &quot;Accept&quot;, &quot;application/json;odata=verbose&quot;
xhr.setRequestHeader &quot;Content-Type&quot;, &quot;application/json;odata=verbose&quot;
xhr.setRequestHeader &quot;X-HTTP-Method&quot;, &quot;MERGE&quot;

Dim json As String
json = &quot;{&quot;&quot;__metadata&quot;&quot;:{&quot;&quot;type&quot;&quot;:&quot;&quot;SP.Data.&quot; &amp; ListName &amp; &quot;Item&quot;&quot;}, &quot;&quot;&quot; &amp; FieldName &amp; &quot;&quot;:&quot;&quot; &amp; NewValue &amp; &quot;&quot;&quot;}&quot;

xhr.send json

Set xhr = Nothing

End Sub
