db2 xml 转 table
版本：DB2 Version 9.11.创建测试表，初始化数据
create table emp (doc XML);
INSERT INTO EMP VALUES ('<dept bldg="101">
<employee id="901">
<name>
<first>John</first>
<last>Doe</last>
</name>
<office>344</office>
<salary currency="USD">55000</salary>
</employee>
<employee id="902">
<name>
<first>Peter</first>
<last>Pan</last>
</name>
<office>216</office>
<phone>905-416-5004</phone>
</employee>
</dept>');
2.利用xmltable方法，将xml格式数据转换为临时table
SELECT X.*
FROM emp,
XMLTABLE ('$d/dept/employee' passing doc as "d"
COLUMNS
empID INTEGER PATH '@id',
firstname VARCHAR(20) PATH 'name/first',
lastname VARCHAR(25) PATH 'name/last') AS X
