Sql server 2008 拆分值，然后将值解析为名称

我需要能够对包含多个值的列（下面）执行一些操作。“HearAboutEvent”列有多个由逗号分隔的值。这些值中的每一个都对应于另一个表中的一个条目。因此，11273的价值等于facebook，11274意味着无线电，11275意味着商业

我正在处理的数据如下所示：

weather ID  MemberID    SubscriptionID  DateEntered     ParticipatedBefore  ParticipatedBeforeCities    WeatherDependent    NonRefundable   TShirtSize  HearAboutEvent
Yes     24      18          1           2013-12-19          0                   NULL                        10950           10952           10957       11273, 11274, 11275

weather ID  MemberID    SubscriptionID  DateEntered     ParticipatedBefore  ParticipatedBeforeCities    WeatherDependent    NonRefundable   TShirtSize  HearAboutEvent
Yes     24      18          1           2013-12-19          0                   NULL                        10950           10952           10957       Facebook, radio, commercial

我能够进行适当的联接来解析“weather”的值，注意它是第一列和第八列

这是我迄今为止创建的查询，用于解析WeatherDependent的值：

SELECT CFS1.Name as 'weather', *
FROM FSM_CustomForm_693 t
LEFT JOIN FSM_CustomFormSelectOptions CFS1 ON CFS1.ID = t.WeatherDependent 
where t.ID = 24

最终，我需要让数据如下所示：

weather ID  MemberID    SubscriptionID  DateEntered     ParticipatedBefore  ParticipatedBeforeCities    WeatherDependent    NonRefundable   TShirtSize  HearAboutEvent
Yes     24      18          1           2013-12-19          0                   NULL                        10950           10952           10957       11273, 11274, 11275

weather ID  MemberID    SubscriptionID  DateEntered     ParticipatedBefore  ParticipatedBeforeCities    WeatherDependent    NonRefundable   TShirtSize  HearAboutEvent
Yes     24      18          1           2013-12-19          0                   NULL                        10950           10952           10957       Facebook, radio, commercial

我认为你可以通过以下方式来实现这一目标：

分割TVF函数-

交叉应用-

STUFF&用于XML路径-&

再往前走一步，你需要这样的东西： 请原谅我大量使用子查询

CREATE FUNCTION dbo.Split (@sep char(1), @s varchar(512))
RETURNS table
AS
RETURN (
    WITH Pieces(pn, start, stop) AS (
      SELECT 1, 1, CHARINDEX(@sep, @s)
      UNION ALL
      SELECT pn + 1, stop + 1, CHARINDEX(@sep, @s, stop + 1)
      FROM Pieces
      WHERE stop > 0
    )
    SELECT pn,
      SUBSTRING(@s, start, CASE WHEN stop > 0 THEN stop-start ELSE 512 END) AS s
    FROM Pieces
  )
GO

您需要的是一个拆分字符串函数。有很多解决方案。这里有一个（）。一旦将字符串分开并分成单独的行，就可以将其连接到另一个表中。
