1.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 |
