DBMS_XMLGEN.GETXML中的多行集-Oracle APEX

在共享组件中的报表查询中添加两个查询并下载XML数据时，输出XML结构类似于以下两行集：

比如：

SELECT '<?xml version="1.0" encoding="UTF-8"?>'
       || XMLElement(
            "DOCUMENT",
            XMLElement(
              "DATA",
              XMLAggregate(
                row_xml
              )
            )
          ).getClobVal() AS xml
FROM   (
  SELECT XMLElement(
           "ROWSET1",
           XMLAggregate(
             XMLElement(
               "ROWSET1_ROW",
               XMLForest(
                 id,
                 name
               )
             )
           )
         ) AS row_xml
  FROM   table1
  UNION ALL
  SELECT XMLElement(
           "ROWSET2",
           XMLAggregate(
             XMLElement(
               "ROWSET2_ROW",
               XMLForest(
                 id AS "ID2",
                 name AS "NAME2"
               )
             )
           )
         )
  FROM   table2
)

比如：

SELECT '<?xml version="1.0" encoding="UTF-8"?>'
       || XMLElement(
            "DOCUMENT",
            XMLElement(
              "DATA",
              XMLAggregate(
                row_xml
              )
            )
          ).getClobVal() AS xml
FROM   (
  SELECT XMLElement(
           "ROWSET1",
           XMLAggregate(
             XMLElement(
               "ROWSET1_ROW",
               XMLForest(
                 id,
                 name
               )
             )
           )
         ) AS row_xml
  FROM   table1
  UNION ALL
  SELECT XMLElement(
           "ROWSET2",
           XMLAggregate(
             XMLElement(
               "ROWSET2_ROW",
               XMLForest(
                 id AS "ID2",
                 name AS "NAME2"
               )
             )
           )
         )
  FROM   table2
)

结果是

<?xml version="1.0"?>
<DOCUMENT>
 <DATA>
  <ROWSET1>
   <ROWSET1_ROW>
    <ID>1</ID>
    <NAME>a</NAME>
   </ROWSET1_ROW>
  </ROWSET1>
  <ROWSET2>
   <ROWSET2_ROW>
    <ID>1</ID>
    <NAME>a</NAME>
   </ROWSET2_ROW>
  </ROWSET2>
 </DATA>
</DOCUMENT>

结果

<?xml version="1.0"?>
<ROWSET>
 <ROW>
  <ROWSET1>
   <ROWSET1_ROW>
    <ID>1</ID>
    <NAME>a</NAME>
   </ROWSET1_ROW>
  </ROWSET1>
  <ROWSET2>
   <ROWSET2_ROW>
    <ID>1</ID>
    <NAME>a</NAME>
   </ROWSET2_ROW>
  </ROWSET2>
 </ROW>
</ROWSET>

结果是

<?xml version="1.0"?>
<DOCUMENT>
 <DATA>
  <ROWSET1>
   <ROWSET1_ROW>
    <ID>1</ID>
    <NAME>a</NAME>
   </ROWSET1_ROW>
  </ROWSET1>
  <ROWSET2>
   <ROWSET2_ROW>
    <ID>1</ID>
    <NAME>a</NAME>
   </ROWSET2_ROW>
  </ROWSET2>
 </DATA>
</DOCUMENT>

结果

<?xml version="1.0"?>
<ROWSET>
 <ROW>
  <ROWSET1>
   <ROWSET1_ROW>
    <ID>1</ID>
    <NAME>a</NAME>
   </ROWSET1_ROW>
  </ROWSET1>
  <ROWSET2>
   <ROWSET2_ROW>
    <ID>1</ID>
    <NAME>a</NAME>
   </ROWSET2_ROW>
  </ROWSET2>
 </ROW>
</ROWSET>
