在sql server中修改xml变量的多个节点的逻辑

Question

我无法在sql server中使用xml数据类型。

我试图在sql server中替换xml变量的多个节点，使用modify（将..替换为..）但是还没有成功。

请您分享一下我如何最好地处理查询的想法？

谢谢...

问题：

在XML（变量）中，我试图将Value元素中的文本设置为＆＃34; White＆＃34;对于CustomProperty Name =＆＃34; Color＆＃34;

的所有属性

Value元素就像Black

但是，Value可以包含任何其他颜色，甚至＆＃34; #rrggbb＆＃34;允许使用RGB代码。

xml：

DECLARE @xmled XML
SET @xmled =
