Question

如何转换MSSQL 2012表（#myTable），如下所示：

name|lastname|child1|age1|child2|age2|child3|age3| prnt|prnt2
Jack|Jones   |Jill  |2   |Joe   |4   |Mike  |5   | Mark| Lizy

到这样的XML格式：

<familyTree>
    <firstname> Jack </firstname>
    <lastname> Jones </lastname>
    <babies>
        <baby> Jill </baby>
        <old> 2 </old> 
    <babies>
    <babies>
        <baby> Joe </baby>
        <old> 4 </old> 
    <babies>
   <babies>
        <baby> Mike </baby>
        <old> 5 </old> 
    <babies>
    <father>Mark </father>
    <mother>lizy </mother>
</familyTree>

这样的选择语句：

SELECT 
    name         AS "firstname",
    lastname     AS "lastname",
    child1       AS "babies/baby",
    age1         AS "babies/old",
    child2       AS "babies/baby",
    age2         AS "babies/old",
    child3       AS "babies/baby",
    age3         AS "babies/old",
    prnt         AS "father",
    prnt2        AS "mother"
FROM  #myTable 
         FOR XML PATH('familyTree')

会导致：

<familyTree>
    <firstname> Jack </firstname>
    <lastname> Jones </lastname>
    <babies>
        <baby> Jill </baby>
        <old> 2 </old> 
        <baby> Joe </baby>
        <old> 4 </old> 
        <baby> Mike </baby>
        <old> 5 </old> 
    <babies>
    <father>Mark </father>
    <mother>lizy </mother>
</familyTree>

该结构与上面给出的所需结构不同。任何帮助或正确方向的步骤将不胜感激？提前谢谢你。

这是诀窍（如果将来有人试图克服同样的情况）。

SELECT 
    name         AS "firstname",
    lastname     AS "lastname",
    child1       AS "babies/baby",
    age1         AS "babies/old",
    '',
    child2       AS "babies/baby",
    age2         AS "babies/old",
    '',
    child3       AS "babies/baby",
    age3         AS "babies/old",
    prnt         AS "father",
    prnt2        AS "mother"
FROM  #myTable 
         FOR XML PATH('familyTree')
