如何使用逗号分隔从SQL查询中获取的多个行

Question

我写了一个查询：

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

结果是：

我从这个查询得到的这些列。请参阅民族列。 它针对单个客户端有3个不同的记录。请告诉我如何在同一列中的单个逗号分隔记录中转换这三个记录，这三行成为一行。

请保存图片然后查看。可能在这里不可见！

您的查询对我来说太过分了。但这是问题的答案......

  

如何逗号分隔从SQL查询中获取的多行

您可以像这样使用for xml path('')。

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  

结果

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

Answer 2

你可以写一个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 
        GL.Id=@ID where GLT.ParentRecordId=2 and GLT.ControlName='CONSUMER_ETHNICITY_LIST')
    return @Ethnicity
END

这只是一个例子，因为我不知道你的数据模型。
