MS Access或MSSQL查询根据单个列中的公共值组合多行数据（从调查猴子导出的数据）

Question

我有以下数据，并希望找到一种方法，使用MS Access SQL或MS SQL Server创建查询以将所有内容合并为一行。

RespondentID  Name             EID       Phone      Why     How          Contact
1809593812                                                  Testing      0
1809593812                                          Testing              0
1809593812                     19091193                                  0
1809593812    Jennifer                                                   0
1809593812                               8885555555                      0

我希望它看起来像：

RespondentID   Name             EID       Phone       Why     How      Contact
1809593812     Jennifer         19091193  8885555555  Testing Testing  0

这是否可以使用MS Access SQL Query或MS SQL Server Query？

还有更多这样的记录。我无法控制其布局，因为它是从外部源每日导出。

到目前为止我在MS Access Query中所拥有的是：

SELECT DISTINCT dbo_ResponsesText.RespondentID,
IIf(dbo_ResponsesText.Key1=4383976121,ResponseText,Null) AS Name, 
IIf(dbo_ResponsesText.Key1=4383976120,ResponseText,Null) AS EID,
IIf(dbo_ResponsesText.Key1=4388819402,ResponseText,Null) AS Phone, 
IIf(dbo_ResponsesText.QuestionID=340372755,ResponseText,Null) AS Why, 
IIf(dbo_ResponsesText.QuestionID=340372805,ResponseText,Null) AS How, 
IIf(dbo_Responses.Key1=4305593988,-1,0) AS Contact
FROM dbo_ResponsesText
INNER JOIN dbo_Responses ON dbo_ResponsesText.RespondentID = dbo_Responses.RespondentID
ORDER BY dbo_ResponsesText.RespondentID

实际表格结构：

dbo_ResponsesText Table
ID   RespondentID  CollectorID  QuestionID  Key1  ResponseText   DateAdded
1    1821607396    25982810     340372755   0     Name,EID,etc.  5/1/2012 3:29:00 PM

dbo_Responses Table:
RespondentID   CollectorID  QuestionID  Key1         Key2  Key3
1809593812     25982810     340372567   4308039090   0     0

Answer 1

您可以尝试以下操作：

You can try the following:

select x.RespondentID, max(x.Name) as Name, max(x.EID) as EID,
       max(x.Phone) as Phone, max(x.Why) as Why, max(x.How) as How, x.Contact
from
(
  SELECT r.RespondentID,
    IIf(t.Key1=4383976121, ResponseText, Null) AS Name, 
    IIf(t.Key1=4383976120 ,ResponseText, Null) AS EID,
    IIf(t.Key1=4388819402, ResponseText, Null) AS Phone, 
    IIf(t.QuestionID=340372755, ResponseText, Null) AS Why, 
    IIf(t.QuestionID=340372805, ResponseText, Null) AS How, 
    IIf(r.Key1=4305593988,-1,0) AS Contact
    FROM dbo_ResponsesText t
    INNER JOIN dbo_Responses r ON t.RespondentID = r.RespondentID
) x
GROUP BY x.RespondentID, x.Contact
ORDER BY x.RespondentID

我已在MS Access 2010中检查了上述代码并且工作正常（已创建表，已填充数据）。随附屏幕截图：初始查询数据（您的）和结果查询数据（我的）

Answer 2

建议Sandr已发布有效我需要做的唯一更改是更改以下转换x.Contact为max（x.Contact）为联系人

更改

选择x.RespondentID，max（x.Name）作为名称，max（x.EID）作为EID，        max（x.Phone）为Phone，max（x.Why）为Why，max（x.How）为How，x .Contact

以

选择x.RespondentID，max（x.Name）作为名称，max（x.EID）作为EID，        max（x.Phone）为Phone，max（x.Why）为Why，max（x.How）为How，max（x.Contact）As Contact

以便最终查询如下：

SELECT 
    x.RespondentID
    , Max(x.Name) AS Name
    , Max(x.EID) AS EID
    , Max(x.Phone) AS Phone
    , Max(x.Why) AS Why
    , Max(x.How) AS How
    , Max(x.Contact) As Contact
FROM (
     SELECT 
        r.RespondentID
            , IIf(t.Key1=4383976121,ResponseText, Null) AS Name
            , IIf(t.Key1=4383976120 ,ResponseText, Null) AS EID
            , IIf(t.Key1=4388819402,ResponseText, Null) AS Phone
            , IIf(t.QuestionID=340372755,ResponseText, Null) AS Why
            , IIf(t.QuestionID=340372805,ResponseText, Null) AS How
            , IIf(r.Key1=4305593988,-1,NULL) AS Contact 
     FROM dbo_ResponsesText AS t 
     INNER JOIN dbo_Responses AS r ON t.RespondentID = r.RespondentID
)  AS x
GROUP BY x.RespondentID
ORDER BY x.RespondentID;

给了我以下所需的输出：

RespondentID  Name     EID       Phone         Why            How            Contact
1811504405    Jenn     123456    456456        Because        Nothing        -1
1820992008    ANDRIA   19289935  909-437-XXXX  Long Response  Long Response   0

For Additional Reference我在MSSQL Server格式中包含了相同类型的Query：

SELECT 
x.RespondentID
    , Max(x.Name) AS Name
    , Max(x.EID) AS EID
    , Max(x.Phone) AS Phone
    , Max(x.Why) AS Why
    , Max(x.How) AS How
    , Max(x.Contact) As Contact
FROM (
    SELECT
     RespondentID = r.RespondentID
     ,Name = 
              CASE WHEN t.[Key1] = '4383976121' THEN [ResponseText] 
              ELSE NULL END

     ,EID = 
              CASE WHEN t.[Key1] = '4383976120' THEN [ResponseText] 
              ELSE NULL END

     ,Phone = 
              CASE WHEN t.[Key1] = '4388819402' THEN [ResponseText] 
              ELSE NULL END

     ,Why = 
              CASE WHEN t.[QuestionID] = '340372755' THEN [ResponseText] 
              ELSE NULL END

     ,How = 
              CASE WHEN t.[QuestionID] = '340372805' THEN [ResponseText] 
              ELSE NULL END

     ,Contact = 
              CASE WHEN r.[Key1] = '4305593988' THEN 'True'
              ELSE 'False' END

     FROM [NPS].[dbo].[ResponsesText] t

     Join [NPS].[dbo].[Responses] r ON t.RespondentID=r.RespondentID
)  AS x
GROUP BY x.RespondentID
ORDER BY x.RespondentID;
