sql - 如何使用 CTE 将一组行和 xml 生成的列插入到单个查询中的表中

Question

我正在生成示例表并使用 cte 从中生成 xml

declare @t table (ID int, PersonID int, Type varchar(10), Name varchar(10),                              
Category varchar(10), value int)
insert @t values
(1, 1234, 'xtype', 'John', 'abc', 200),
(2, 1234, 'ytype', 'John', 'xyz', 230),
(3, 1234, 'ztype', 'John', 'ccc', 220),
(4, 2222, 'xtype', 'Jim', 'abc', 200),
 (5, 3333, 'xtype', 'Tim', 'abc', 500)

; with cte
as (
select distinct PersonID from @t
 )
 select
(select
    PersonID,
    (select
         Type,
         Name,
         category,
         value
     from
         @t t
     where
         t.PersonID = cteInner.PersonID
     for xml path('SpecifiedType'), type ) 
from
    cte cteInner
where
    cteInner.PersonID = cteOuter.PersonID
for xml path(''), type, root('data') ) as xmldetail
from 
cte cteOuter

现在我想将以下数据插入到另一个表中，包括我创建的其他数据列的 xml

  Example Table
  PersonID   Name           xmldetail
  1234       John        (GeneratedXmlFrom using cte)
  2222       Jim         (GeneratedXmlFrom using cte)
  3333       Tim         (GeneratedXmlFrom using cte)

Answer 1

declare @t table (ID int, PersonID int, Type varchar(10), Name varchar(10),                              
Category varchar(10), value int)
insert @t values
(1, 1234, 'xtype', 'John', 'abc', 200),
(2, 1234, 'ytype', 'John', 'xyz', 230),
(3, 1234, 'ztype', 'John', 'ccc', 220),
(4, 2222, 'xtype', 'Jim', 'abc', 200),
 (5, 3333, 'xtype', 'Tim', 'abc', 500)
;WITH cte
AS (
    SELECT DISTINCT PersonID
        ,NAME
    FROM @t
    )
 insert into TABLENAME
SELECT PersonID
    ,NAME
    ,(
        SELECT PersonID
            ,(
                SELECT Type
                    ,NAME
                    ,category
                    ,value
                FROM @t t
                WHERE t.PersonID = cteInner.PersonID
                FOR XML PATH('SpecifiedType')
                    ,TYPE
                )
        FROM cte cteInner
        WHERE cteInner.PersonID = cteOuter.PersonID
        FOR XML PATH('')
            ,TYPE
            ,ROOT('data')
        ) AS xmldetail
FROM cte cteOuter

您必须在选择列表中添加名称和 ID

SELECT PersonID、姓名

还必须在 CTE 选择语句中包含 Name

对/对

1234    John    <data><PersonID>1234</PersonID><SpecifiedType><Type>xtype</Type><Name>John</Name><category>abc</category><value>200</value></SpecifiedType><SpecifiedType><Type>ytype</Type><Name>John</Name><category>xyz</category><value>230</value></SpecifiedType><SpecifiedType><Type>ztype</Type><Name>John</Name><category>ccc</category><value>220</value></SpecifiedType></data>
2222    Jim     <data><PersonID>2222</PersonID><SpecifiedType><Type>xtype</Type><Name>Jim</Name><category>abc</category><value>200</value></SpecifiedType></data>
3333    Tim     <data><PersonID>3333</PersonID><SpecifiedType><Type>xtype</Type><Name>Tim</Name><category>abc</category><value>500</value></SpecifiedType></data>

要将值插入另一个表，请使用 insert into TABLENAME
