    Delete property content of all children of given node via SQL query


    Given a node with ID "X", how can we delete the values/content of a property with alias "Y" of all the children (and their children) pages of node "X", via an SQL Server query?

    So that only the content of the properties will be empty, not deleting the property itself, just their values.

    The property we need to empty is a nested content type, all its items need to be removed.

    You can use something like this:

    update upd
    set  varcharValue = null, textValue = null
    from umbracoPropertyData upd
    join umbracoContentVersion cv on = upd.versionId
    join umbracoNode un on = cv.nodeId
    join cmsPropertyType pt on = upd.propertyTypeId
    where un.nodeObjectType like 'C66BA18E-EAF3-4CFF-8A22-41B16D66A972' and Alias like 'title' and  (cv.nodeId = 1053 or un.[path]  like '%1053,%')

    Just replace the 'title' with Y, and replace the 1053 with the X
