如何逗號分隔的多個行從SQL查詢

我寫了一個查詢中獲得：如何逗號分隔的多個行從SQL查詢

select tbl1.Id, tbl1.FirstName, tbl1.MiddleInit, tbl1.LastName, tbl1.SocialSecNum, tbl1.DateOfBirth, 
tbl1.EyeColor, tbl1.Sex, tbl1.AlertNotes, tbl1.RiskNotes, tbl1.Height, tbl1.[Weight], tbl1.AllergyNotes, 
tbl2.HairColor, tbl3.SexualConsent, tbl4.MaritalStatus, tbl5.Ethnicity, tbl6.Veteran, tbl7.Religion, tbl8.Race, 
tbl9.[Language] as [Language] 

from 

(SELECT C.Id, C.FirstName, C.MiddleInit, C.LastName, C.SocialSecNum, C.DateOfBirth, C.Sex, 
GL.LookupItem as EyeColor, CC.AlertNotes, CC.RiskNotes, CC.Height, CC.[Weight], CC.AllergyNotes 
FROM dbo.Client C INNER JOIN dbo.ClientCharacteristic CC ON C.Id = CC.ClientId INNER JOIN dbo.GeneralLookup GL ON 
GL.Id=CC.glEyeColorId) tbl1, 

(SELECT GL.LookupItem as HairColor 
FROM dbo.ClientCharacteristic CC INNER JOIN dbo.GeneralLookup GL ON 
GL.Id=CC.glHairColorId) tbl2, 

(SELECT GL.LookupItem as SexualConsent 
FROM dbo.ClientCharacteristic CC INNER JOIN dbo.GeneralLookup GL ON 
GL.Id=CC.glSexConsentId) tbl3, 

(SELECT GL.LookupItem as MaritalStatus 
FROM dbo.Client C INNER JOIN dbo.GeneralLookup GL ON 
GL.Id=C.glMaritalStatusId where C.Id=2) tbl4, 

(SELECT GL.LookupItem as Ethnicity 
FROM dbo.GeneralLookupTransition GLT INNER JOIN dbo.GeneralLookup GL ON 
GL.Id=GLT.glValueId where GLT.ParentRecordId=2 and GLT.ControlName='CONSUMER_ETHNICITY_LIST') tbl5, 

(SELECT GL.LookupItem as Veteran 
FROM dbo.Client C INNER JOIN dbo.GeneralLookup GL ON 
GL.Id=C.glVeteranId where C.Id=2) tbl6, 

(SELECT GL.LookupItem as Religion 
FROM dbo.GeneralLookupTransition GLT INNER JOIN dbo.GeneralLookup GL ON 
GL.Id=GLT.glValueId where GLT.ParentRecordId=2 and GLT.ControlName='CONSUMER_RELIGION_DROPDOWN') tbl7, 

(SELECT GL.LookupItem as Race 
FROM dbo.GeneralLookupTransition GLT INNER JOIN dbo.GeneralLookup GL ON 
GL.Id=GLT.glValueId where GLT.ParentRecordId=2 and GLT.ControlName='CONSUMER_RACE_DROPDOWN') tbl8, 

(SELECT GL.LookupItem as [Language] 
FROM dbo.GeneralLookupTransition GLT INNER JOIN dbo.GeneralLookup GL ON 
GL.Id=GLT.glValueId where GLT.ParentRecordId=2 and GLT.ControlName='CONSUMER_CHARACTERISTIC_LANGUAGE_DROPDOWN') tbl9

結果是：

這一些我從這個查詢得到的列。查看專欄種族。它有3個不同的記錄針對單個客戶端。請告訴我如何將這三條記錄轉換爲同一列中的單個逗號分隔記錄，並將這三行記錄成單行。

請保存圖像，然後看。可能是這裏不可見！

爲什麼不從查詢中返回多個表並在asp.net中建立它們之間的關係？ – 2011-04-04 09:39:21

不，我不能。我只需要這個Ehtnicity逗號分隔。這是要求。 – asma 2011-04-04 09:43:40

您的查詢對我來說有點過分。但這裏是問題的答案......從SQL查詢

獲得您可以使用for xml path('')這樣

如何逗號分隔的多個行。

declare @T table (GroupID int, Value varchar(10)) 

insert into @T values (1, 'Row 1') 
insert into @T values (1, 'Row 2') 
insert into @T values (2, 'Row 3') 
insert into @T values (2, 'Row 4') 
insert into @T values (2, 'Row 5') 

select GroupID, 
    stuff(
    (select ','+Value as '*' 
    from @T as T2 
    where T2.GroupID = T1.GroupID 
    for xml path('')), 1, 1, '') as [Values] 
from @T as T1 
group by GroupID

結果

GroupID  Values 
----------- ------------------ 
1   Row 1,Row 2 
2   Row 3,Row 4,Row 5

好答案;在http://www.sqlservercurry.com/2011/03/sql-server-combine-multiple-rows-into.html上有一篇類似於此解決方案的博客文章，其中詳細介紹了爲什麼會這樣工作。 – 2011-04-04 13:25:50

你可以寫一個UDF：

CREATE FUNCTION [dbo].[getEthnicity] 
(
    @id Int, 
    @delimiter varchar(5) 
) 
RETURNS VARCHAR(8000) 
AS 
BEGIN 
    DECLARE @Ethnicity VARCHAR(8000) 
    SELECT @Ethnicity = COALESCE(@Ethnicity + @delimiter, '') + GLT.DisplayColumn  
    FROM dbo.GeneralLookupTransition GLT INNER JOIN dbo.GeneralLookup GL ON 
     [email protected] where GLT.ParentRecordId=2 and GLT.ControlName='CONSUMER_ETHNICITY_LIST') 
    return @Ethnicity 
END

這僅僅是因爲我不知道你的數據模型的例子。
