返回Xml和Html的SQL Server查询

Question

我们正在将一个应用程序从oracle迁移到SQL Server。

在Oracle中，一个过程用于返回嵌入了一些HTML标记的XML。

来源如下。

SELECT XMLAGG (
       XMLFOREST (
        XMLELEMENT ("a", XMLATTRIBUTES ('#' AS "href"), MODULENAME) "h3", 
        XMLELEMENT (
        "ul", 
        XMLAGG (
         XMLELEMENT (
          "li", 
          XMLELEMENT (
           "a", 
           XMLATTRIBUTES (
           '#' AS "href", 
            'pageclick(''' 
           || SCREENPATH              
           || ''','|| SCREENID||')' AS "onclick"), 
           SCREENNAME)) 
          ORDER BY SORDER ASC)) "div") 
        ORDER BY MORDER ASC).getclobval() 

     FROM (SELECT B.SUBMODULEID MODULEID, 
        C.PAGEID SCREENID, 
        C.PAGENAME SCREENNAME, 
        C.PAGECODE, 
        B.SUBMODULEID, 
        B.SUBMODULENAME MODULENAME, 
        C.PAGEURLL1 SCREENPATH, 
        C.ORDERNO SORDER, 
        B.ORDERNO MORDER 
       FROM SETP.SM_PAGES C, 
        SETP.SM_MODULES A, 
        SETP.SM_SUB_MODULES B, 
        SETP.SM_USRPRIVHDR D, 
        SETP.SM_USRPRIVDTL E 
       WHERE  D.USRPRIVID = E.USRPRIVID 
        AND C.PAGEID = E.PAGEID 
        AND B.MODULEID = A.MODULEID 
        AND C.SUBMODULEID = B.SUBMODULEID 
        AND D.USRID = 2) page 
    GROUP BY MODULENAME, MORDER; 

，这里是输出

<h3> 
    <a href="#">Masters</a> 
</h3> 
<div> 
    <ul> 

     <li> 
      <a href="#" onclick="pageclick(&apos;WmsSetup.aspx/BaggingConfig&apos;,1177)">Bagging Configuration</a> 
     </li> 
     <li> 
      <a href="#" onclick="pageclick(&apos;WMS.aspx/Items&apos;,1171)">Item Master</a> 
     </li> 

    </ul> 
</div> 

我一直在分裂我的头发，实现SQL Server中的相同，而无需使用XSLT。 任何想法？

感谢&问候

这看起来像它应该为你工作。

;with C as 
(

    -- Your derived table goes here 
    SELECT B.SUBMODULEID MODULEID, 
     C.PAGEID SCREENID, 
     . 
     . 
    FROM SETP.SM_PAGES C, 
     . 
     . 

) 
select '#' as "h3/a/@href", 
     MODULENAME as "h3/a", 
     (
     select '#' as "a/@href", 
       'pageclick('''+SCREENPATH+''','+SCREENID+')' as "a/@onclick", 
       SCREENNAME as "a" 
     from C as C2 
     where C1.MODULENAME = C2.MODULENAME and 
       C1.MORDER = C2.MORDER 
     for xml path('li'), root('ul'), type 
     ) as "div" 
from C as C1 
group by MODULENAME, MORDER 
for xml path('') 

我使用公用表表达式（CTE），因为我需要重用派生表来创建XML的内部部件。

这是一个带有表变量而不是子查询的工作示例。

declare @T table 
(
    MODULEID int, 
    SCREENID varchar(10), 
    SCREENNAME varchar(35), 
    PAGECODE varchar(10), 
    SUBMODULEID int, 
    MODULENAME varchar(10), 
    SCREENPATH varchar(35), 
    SORDER int, 
    MORDER int 
) 

insert into @T values 
(1, '1177', 'Bagging Configuration', 'page', 3, 'Masters', 'WmsSetup.aspx/BaggingConfig', 4, 5) 
insert into @T values 
(1, '1171', 'Item Master', 'page', 3, 'Masters', 'WMS.aspx/Items', 4, 5) 

;with C as 
(
    select * 
    from @T 
) 
select '#' as "h3/a/@href", 
     MODULENAME as "h3/a", 
     (
     select '#' as "a/@href", 
       'pageclick('''+SCREENPATH+''','+SCREENID+')' as "a/@onclick", 
       SCREENNAME as "a" 
     from C as C2 
     where C1.MODULENAME = C2.MODULENAME and 
       C1.MORDER = C2.MORDER 
     for xml path('li'), root('ul'), type 
     ) as "div" 
from C as C1 
group by MODULENAME, MORDER 
for xml path('') 

结果：

<h3> 
    <a href="#">Masters</a> 
</h3> 
<div> 
    <ul> 
    <li> 
     <a href="#" onclick="pageclick('WmsSetup.aspx/BaggingConfig',1177)">Bagging Configuration</a> 
    </li> 
    <li> 
     <a href="#" onclick="pageclick('WMS.aspx/Items',1171)">Item Master</a> 
    </li> 
    </ul> 
</div>
