Question

我尝试使用Oracle SQL从以下XML中提取值，并以xml_table格式存储为XMLType。

select x.*
from xml_table t  
 , xmltable( XMLNAMESPACES (
  'http://schemas.xmlsoap.org/soap/envelope/' AS "env",
  'urn:com.workday/bsvc' as "wd"
),  'for $i in //wd:Get_Worker_Costing_Allocations_Response return $i' 
 --,'env:Envelope/env:Body/wd:Get_Worker_Costing_Allocations_Response/wd:Response_Data/wd:Worker_Costing_Allocations_Data'  
     passing t.raw_xml  
     columns Employee_ID number        path 'wd:Response_Data/wd:Worker_Costing_Allocations_Data/wd:Worker_Reference/wd:ID[2]'
            ,Position_ID        varchar2(100) path 'wd:Response_Data/wd:Worker_Costing_Allocations_Data/wd:Position_Reference/wd:ID[2]'
            --,start_Date     date path   'wd:Response_Data/wd:Worker_Costing_Allocations_Data/wd:Worker_Costing_Allocation_Interval_Data/wd:Start_Date' 
   ) x

当我尝试获取基金ID时，Cost_Center_Reference_ID等其他详细信息无法从Worker_Costing_Allocation_Interval_Data获取。最终我必须遍历所有Worker_Costing_Allocation_Interval_Data个节点。

select x.*
   from xml_table t  
     , xmltable( XMLNAMESPACES (
      'http://schemas.xmlsoap.org/soap/envelope/' AS "env",
      'urn:com.workday/bsvc' as "wd"
    ),  'for $i in //wd:Worker_Costing_Allocation_Detail_Data return $i' 
     --,'env:Envelope/env:Body/wd:Get_Worker_Costing_Allocations_Response/wd:Response_Data/wd:Worker_Costing_Allocations_Data'  
         passing t.raw_xml  
         columns order_1     varchar2(20) path   'wd:Order'
                 ,fund_id     varchar2(20) path   'wd:Costing_Override_Worktag_Reference/wd:ID[@Fund_ID]' 
       ) x

预期产出：

employee_id Position_Id Start_Date  End_Date    Order   Fund_ID Project_ID  Program_ID  Cost_Center_Reference_ID    Custom_Organization_Reference_ID    Distribution_Percent
11111   P11111  7/1/2018    6/30/2050   a   FD89    PJ122201    PG11130 CC12340     0.4
11111   P11111  7/1/2018    6/30/2050   b   FD89    PJ122201    PG11130 CC1234      0.6
11111   P11111  7/1/2017    6/30/2018   a   FD30    PJ000001    PG00003 CC0565  UD000004    1

以下是插入xml_table的原始XML：

如果需要从多个级别获取数据，每个级别都有多个节点，则可以使用多个XMLTable构造：

select x1.employee_id, x1.position_id,
  to_date(x2.start_date, 'YYYY-MM-DD-HH24:MI') as start_date,
  x2.order_1, x2.fund_id
from xml_table t
cross join xmltable (
  xmlnamespaces ('http://schemas.xmlsoap.org/soap/envelope/' AS "env",
      'urn:com.workday/bsvc' as "wd"),
    '/env:Envelope/env:Body/wd:Get_Worker_Costing_Allocations_Response/wd:Response_Data/wd:Worker_Costing_Allocations_Data'
    passing t.raw_xml  
    columns Employee_ID number path 'wd:Worker_Reference/wd:ID[@wd:type="Employee_ID"]',
      Position_ID varchar2(100) path 'wd:Position_Reference/wd:ID[@wd:type="Position_ID"]',
      Interval_Data xmltype path 'wd:Worker_Costing_Allocation_Interval_Data'
) x1
cross join xmltable (
  xmlnamespaces ('urn:com.workday/bsvc' as "wd"),

第一个XMLTable获取员工和职位ID，以及自己的XMLType，即Worker_Costing_Allocation_Interval_Data片段。第二个XMLTable传递该片段，并在该级别提取多个值。如果需要，你可以降低更多级别。

请注意，某些节点的特定实例的过滤器已更改;例如，我没有使用[2]来获取第二个工作者引用ID，而是查找了具有[@wd:type="Employee_ID"]等的特定属性值。并且对基金ID提起了类似的构造;你的原始代码是为了一个名为Fund_ID的属性，而不是那个具有该类型值的属性。

您可以在一个级别执行此操作，但备份树的引用可能会有点混乱。这将获得您想要的所有字段：

select x.employee_id, x.position_id,
  to_date(x.start_date, 'YYYY-MM-DD-HH24:MI') as start_date,
  to_date(x.end_date, 'YYYY-MM-DD-HH24:MI') as end_date,
  x.order_1, x.fund_id, x.project_id, x.program_id, x.Cost_Center_Reference_ID,
  x.custom_organization_ref_id, x.distribution_percent

~~我已经注释了Custom_Organization_Reference_ID因为有重复项 - LOA和UD000004 - 所以你可能不得不回到多个XMLTable来处理它。~~

根据您的评论，这只会找到以Custom_Organization_Reference_ID开头的UD。

使用xmltable和XMLNAMESPACES提取数据
