Hi, You may refer to the [UPDATE Statement]( section of the Virtual DataPort VQL Guide to understand the syntax on executing an UPDATE statement. However, note that there are conditions that needs to be met before a view can be updated. For example, a derived view is not updateable if its underlying view is not updateable. You may find these conditions under the [Inserts, Updates and Deletes Over Views]( section of the Virtual DataPort VQL Guide too. Hope this helps!
