SQL查询 生成XML

1

select t.UserNameXML.value('(/b/UserName)[1]','varchar(20)') as Name /*查询XML中的UserName值*/
from
(select a.* ,(select b.UserName from dbo.T_UserLogin b where b.LoginId=a.LoginId  for xml auto, type, elements) as UserNameXML
from T_UserInfo a) t

查询结果：



其中以下这条语句查询结果是：

select a.* ,(select b.UserName from dbo.T_UserLogin b where b.LoginId=a.LoginId for xml auto, type, elements) as UserNameXML
from T_UserInfo a查询结果：



将XML序列化成一个Liset对象，和一个对象

protected List<T> XmlListInit<T>(string value) where T : BaseTO, new()
{
var objs = new List<T>();
XmlDocument doc = new XmlDocument();
XmlElement root = doc.CreateElement("root");
doc.AppendChild(root);
root.InnerXml = value;
foreach (XmlNode node in root.ChildNodes)
{
var o = new T();
o.Initialize(node);
objs.Add(o);
}
return objs;
}

protected T XmlInit<T>(string value) where T : BaseTO, new()
{
var obj = new T();
XmlDocument doc = new XmlDocument();
XmlElement root = doc.CreateElement("root");
doc.AppendChild(root);
root.InnerXml = value;
if (value != null)
{
obj.Initialize(root.FirstChild);
}
return obj;
}
