您可以在属性名称中添加一个行号，该行号将允许您执行所需的操作:

You can add a row number to the propertyname that will allow you to do what you want:

SELECT * FROM
(
SELECT ENTITYID
       , PROPERTYNAME = PROPERTYNAME + CAST(ROW_NUMBER() OVER(PARTITION BY ENTITYID, PROPERTYNAME ORDER BY PROPERTYVALUE) AS VARCHAR(5))
      ,PROPERTYVALUE
FROM #STAGING   
) AS T
PIVOT (MAX(PROPERTYVALUE) FOR PROPERTYNAME IN (NAME1, SPOUSE1, CHILD1, CHILD2, CHILD3, CHILD4, CHILD5)) AS T2

我在这里假设ENTITYID将孩子与父母联系起来，即同一个人的所有孩子的ENTITYID为1，但是您的示例为Kayala展示了2.

I'm assuming here that the ENTITYID ties the children to the parent, ie all children for the same person have ENTITYID of 1, but your example shows a 2 for Kayala.

这里是一个演示: SQL Fiddle

如果您只想要CHILD字段的数字，则可以输入以下内容:

If you only want the numbers for the CHILD fields you could put this:

PROPERTYNAME = CASE WHEN PROPERTYNAME LIKE '%CHILD%' THEN PROPERTYNAME + CAST(ROW_NUMBER() OVER(PARTITION BY ENTITYID, PROPERTYNAME ORDER BY PROPERTYVALUE) AS VARCHAR(5))                                                   ELSE PROPERTYNAME END

然后从IN()语句中的其他字段中删除该数字.

Then remove the number from the other fields in your IN() statement.

奖金问题-动态执行上述操作: 我们不想假设人们只有一个配偶或2.3个孩子，因此我们会动态地进行全部操作:

Bonus Question- Do the above dynamically: We don't want to assume that people only have one spouse or 2.3 children, so we do the whole bit dynamically:

DECLARE @cols AS NVARCHAR(MAX),
    @query  AS NVARCHAR(MAX)

SELECT @cols = STUFF((SELECT ',' + PROPERTYNAME
                    FROM (SELECT DISTINCT PROPERTYNAME = PROPERTYNAME + CAST(ROW_NUMBER() OVER(PARTITION BY ENTITYID, PROPERTYNAME ORDER BY PROPERTYVALUE) AS VARCHAR(5))
                          FROM STAGING )sub
                    ORDER BY CASE WHEN PROPERTYNAME LIKE '%NAME%' THEN 1
                        WHEN PROPERTYNAME LIKE '%SPOUSE%' THEN 2
                        WHEN PROPERTYNAME LIKE '%CHILD%' THEN 3
                    ELSE 4
                    END
                    ,RIGHT(PROPERTYNAME,1) 
                  FOR XML PATH(''), TYPE
            ).value('.', 'NVARCHAR(MAX)') 
        ,1,1,'')


SET @query = 'SELECT * FROM
                (
                SELECT ENTITYID, PROPERTYNAME = PROPERTYNAME + CAST(ROW_NUMBER() OVER(PARTITION BY ENTITYID, PROPERTYNAME ORDER BY PROPERTYVALUE) AS VARCHAR(5)),PROPERTYVALUE
                FROM STAGING   
                ) AS T
                PIVOT (MAX(PROPERTYVALUE) FOR PROPERTYNAME IN ('+@cols+')) AS T2

'
EXEC(@query)

注意:此顺序仅适用于1-9岁的配偶和1-9岁的孩子，您可以对其进行调整以适合自己，但这仍然是任意的.

Note: The ordering will only work for spouses 1-9 and children 1-9, you can adjust that to suit, but it's arbitrary anyway.
