有没有办法将这两个替换值与1个更新语句组合在一起？
UPDATE dbo.MyTable
SET MyXmlColumn.modify('replace value of (/node/@att1)[1] with "1"')
WHERE id = 1
UPDATE dbo.MyTable
SET MyXmlColumn.modify('replace value of (/node/@att2)[1] with "2"')
WHERE id = 1

我不认为你很幸运,Thx.
我尝试了几种没有快乐的语法变体.例如,显而易见的：
SET MyXmlColumn.modify('...'),MyXmlColumn.modify('...')
收益率：
The column name ‘MyXmlColumn’ is specified more than once in the SET
clause. A column cannot be assigned more than one value in the same
SET clause. Modify the SET clause to make sure that a column is
updated only once. If the SET clause updates columns of a view,then
the column name ‘MyXmlColumn’ may appear twice in the view
definition.
但是对于XML DML空间中的此错误消息没有任何帮助.
底线是Expression1& Expression2必须是单个元素.
即便是最彻底的讨论最终也会绕过它……
