I have successfully created a CAML query to sort my list by modified date but I want published date instead. Why does replacing "Modified" with "Published" not work? They are both "Date and Time" columns in the list when I look at List Settings but the published column must have a different name for some reason? (This is in SharePoint 2013)
query.Query = "<OrderBy><FieldRef Name='Modified' Ascending='False'/><Value Type='DateTime' IncludeTimeValue='True'></Value></OrderBy>";
