问题 I have a Table with an XML column, I want to update the xml to insert attribute or to change the attribute value if the attribute already exists. Let's say the starting xml is: < d /> Inserting: UPDATE Table set XmlCol.modify('insert attribute att {"1"} into /d[1]') Changing: UPDATE Table set XmlCol.modify('replace value of /d[1]/@att with "1"') insert will fail if the attribute already exists, replace will fail if the attribute doesn't exists.

问题 Is the result of a SELECT like the one below using XQuery in SQL Server guaranteed to be in document order, that is in the original order the nodes are listed in the xml string? DECLARE @x XML = '<hey i="3"/><hey i="4"/><hey i="0"/>' SELECT t.i.value('.', 'int') FROM @x.nodes('/hey/@i') t(i) I ask because in general SELECT statements do not guarantee an order unless one is provided.
