Question

我想用对应的值替换ID

示例：如果列包含ID 1,2，
我需要将1替换为“产品视频”，将2替换为“安装”。我可以使用用例，但找不到用逗号分隔ID的用例的方法

SELECT BusinessFocus
    ,(
        SELECT stuff((
                    SELECT ', ' + BusinessFocus
                        ,CASE 
                            WHEN BusinessFocus = 1
                                THEN 'Product Videos'
                            WHEN BusinessFocus = 2
                                THEN 'Installation Videos'
                            WHEN BusinessFocus = 3
                                THEN 'Other Videos'
                            END AS BFocusname
                    WHERE BusinessFocus IN (
                            SELECT val
                            FROM dbo.split(PartnerMaster.BusinessFocus, ',')
                            )
                    FOR XML PATH('')
                    ), 1, 1, '')
        ) AS BusinessFocusNames
FROM PartnerMaster

实际结果：

预期结果：

   1,3    |  Product Videos,Installation Videos

Answer 1

如果您只是想将“ 1,3”转换为“产品视频，其他视频”，则可以按以下方式使用REPLACE-

DECLARE @BusinessFocus VARCHAR(200) = '1,3'

SELECT @BusinessFocus, 
REPLACE(REPLACE(@BusinessFocus,'1','Product Videos'),'3','Other Videos')

注意：您可以再使用一个REPLACE，如图所示。

Answer 2

如果您没有将这些业务重点值存储在表中的其他位置，请使用CTE。

模式：

CREATE TABLE #PartnerMaster (BusinessFocus VARCHAR(100), BusinessFocusNames VARCHAR(MAX))

INSERT INTO #PartnerMaster (BusinessFocus)
SELECT '1,2' UNION ALL SELECT '3' UNION ALL SELECT '2,3'

现在加入Charindex，并用For XML Path使其用逗号分隔。

;WITH CTE AS(
SELECT '1' BusinessFocus, 'Product Videos' BusinessFocusNames
UNION ALL
SELECT '2' BusinessFocus, 'Installation Videos' BusinessFocusNames
UNION ALL
SELECT '3' BusinessFocus, 'Other Videos' BusinessFocusNames
)
SELECT P.BusinessFocus
, STUFF((SELECT ','+C.BusinessFocusNames FROM CTE C 
         WHERE CHARINDEX(C.BusinessFocus,P.BusinessFocus)>0
         FOR XML PATH('')),1,1,'') AS  BusinessFocusNames
FROM #PartnerMaster P

结果：

+---------------+------------------------------------+
| BusinessFocus |         BusinessFocusNames         |
+---------------+------------------------------------+
| 1,2           | Product Videos,Installation Videos |
| 3             | Other Videos                       |
| 2,3           | Installation Videos,Other Videos   |
+---------------+------------------------------------+

需要绑定值代替id（逗号分隔）
