Question

我已经浏览过一系列关于SO的例子和其他问题，但我仍然遇到这个问题的问题。

select [Address],[Address 1],[Address 2],[Address2],[Birth Day],[City],
       [Email],[First Name],[Last Name],[Phone],[State],[Zip]
from 
(SELECT *, row_number() over(PARTITION by formid order by formid) as rnk   
 FROM [Sitecore_WebForms].[dbo].[Field] 
 where FormId='C9681226-5951-403D-80A0-00019218785C'
) as SourceTable
pivot
(
max(value)
for [fieldname] in 
([Address],[Address 1],[Address 2],[Address2],[Birth Day],[City],[Email],
 [First Name],[Last Name],[Phone],[State],[Zip])
) as pt

结果返回9行，每列1行。如何将这些行组合成一行？

Address Address 1   Address 2   Address2    Birth Day   City    Email   First Name  Last Name   Phone   State   Zip
NULL    NULL    NULL    NULL    NULL    NULL    NULL    FIRS    NULL    NULL    NULL    NULL
NULL    NULL    NULL    NULL    NULL    CITY    NULL    NULL    NULL    NULL    NULL    NULL
NULL    NULL    NULL    NULL    NULL    NULL    NULL    NULL    LAST    NULL    NULL    NULL
NULL    NULL    NULL    NULL    NULL    NULL    NULL    NULL    NULL    NULL    NULL    ZIP
ADDR    NULL    NULL    NULL    NULL    NULL    NULL    NULL    NULL    NULL    NULL    NULL
NULL    NULL    NULL    NULL    DATE    NULL    NULL    NULL    NULL    NULL    NULL    NULL
NULL    NULL    NULL    NULL    NULL    NULL    EMAI    NULL    NULL    NULL    NULL    NULL
NULL    NULL    NULL    NULL    NULL    NULL    NULL    NULL    NULL    PHON    NULL    NULL
NULL    NULL    NULL    NULL    NULL    NULL    NULL    NULL    NULL    NULL    NULL    NULL

如果我们只从Source中选择value和filedName，它将按预期工作。

select [Address],[Address 1],[Address 2],[Address2],[Birth Day],[City],
       [Email],[First Name],[Last Name],[Phone],[State],[Zip]
from 
(SELECT value, fieldname   
 FROM [Sitecore_WebForms].[dbo].[Field] 
 where FormId='C9681226-5951-403D-80A0-00019218785C'
) as SourceTable
pivot
(
max(value)
for [fieldname] in 
([Address],[Address 1],[Address 2],[Address2],[Birth Day],[City],[Email],
 [First Name],[Last Name],[Phone],[State],[Zip])
) as pt

所有表格的更新：

DECLARE @form TABLE 
( 
    id INT, 
    formid INT,
    fieldName VARCHAR(32),
    fieldValue VARCHAR(32)
)

insert into @form values(1,1,'First Name','FRST')
insert into @form values(2,1,'Last Name','LST')
insert into @form values(3,1,'Address','ADDR')
insert into @form values(4,2,'First Name','FRST2')
insert into @form values(5,2,'Last Name','LST2')
insert into @form values(6,2,'Address','ADDR2')



select FormId,[Address],[Address 1],[Address 2],[Address2],[Birth Day],[City],
       [Email],[First Name],[Last Name],[Phone],[State],[Zip]
from 
(SELECT FormId,fieldName,fieldValue
 FROM @form 
 --where FormId=1
) as SourceTable
pivot
(
max(fieldValue)
for [fieldname] in 
([Address],[Address 1],[Address 2],[Address2],[Birth Day],[City],[Email],
 [First Name],[Last Name],[Phone],[State],[Zip])
) as pt

PIVOT只会“轮换”您列出的列;任何其他列仍将隐藏自己的行。在您的情况下，Id和FieldId都会导致每行保留。

要解决此问题，请在子查询中排除这些列：

select  *
from    (
        select  FormId
        ,       Value
        ,       FieldName 
        from    @t 
        ) as SourceTable        
pivot   (
        max(value) 
        for FieldName in 
        (Address,[Address 1],[Address 2],Address2,...)
        ) as PivotAlias;
