用表列名作为XML标记在SQL中构造XML

我需要以XML格式获取表的模式

考虑一个具有列的TablePerson：

ID varchar（10）标识、名称varchar（20）、名称varchar（10）

我需要XML的格式

<Persons>
<Person LocalizationSetting = {today's date}>
<ID type=varchar length =10 required=true/>
<Nametype=varchar length =20 required=true/>
<Designation  type=varchar length =10 required=true/>
</Person>
</Persons>

我得到以下结果：

<Patients>
  <column column_name="ID" type="varchar"  maxLength="10" required="true" />
  <column column_name="Name" type="varchar" maxLength="20" required="true" />
  <column column_name="Designation" type="varchar" maxLength="10" required="true" />
</Patients>

是否可以将列名作为预期结果中显示的标记？

您应该解决此问题

我需要以XML格式获取表的模式

。。。具有标准内置功能。您作为预期输出提供的模式可能是一些自定义结构。。。看看这个：

CREATE TABLE Person  (ID VARCHAR(10) NOT NULL
                     ,NameType VARCHAR(20) NOT NULL
                     ,Designation VARCHAR(10) NOT NULL);
INSERT INTO Person VALUES('SomeID','SomeType','SomeDes');

SELECT * FROM Person FOR XML AUTO,XMLDATA;

--XMLDATA返回此模式

    <attribute type="ID" />
    <attribute type="NameType" />
    <attribute type="Designation" />

结果

<Persons>
  <Person LocalizationSetting="2017-04-18T11:05:30.047">
    <ID type="varchar" length="10" required="true" />
    <NameType type="varchar" length="20" required="true" />
    <Designation type="varchar" length="10" required="true" />
  </Person>
</Persons>
