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

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

这可以使用 MS Access SQL Query 或 MS SQL Server Query 吗？

这样的记录还有很多。我无法控制它的布局，因为它是每天从外部来源导出的。

到目前为止，我在 MS Access Query 中拥有的是：

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

您可以尝试以下方法：

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

我在 MS Access 2010 中检查了上面的代码，它工作正常（创建了表，填充了数据）。附截图：使用数据的初始查询（你的）和使用数据的结果查询（我的） 原始查询 - 初始状态 修改后的查询

Sandr Posted 的建议是有效的，我需要做的唯一更改是更改以下将 x.Contact 转换为 max(x.Contact) 作为联系人

改变

选择 x.RespondentID，max(x.Name) 作为 Name，max(x.EID) 作为 EID，max(x.Phone) 作为 Phone，max(x.Why) 作为Why，max(x.How) 作为 How， x.联系方式

至

选择 x.RespondentID，max(x.Name) 作为 Name，max(x.EID) 作为 EID，max(x.Phone) 作为 Phone，max(x.Why) 作为Why，max(x.How) 作为 How， max(x.Contact) 作为联系人

这样最终的查询看起来像：

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;

这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

对于其他参考，我在 MSSQL Server 格式中包含了相同类型的查询：

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;
