查询SQL上的GROUPBY子句

在sql 2008中，我成功地将分号分隔的值分隔为多行。现在我需要的是Count*语句

ID Answers
1  Agent;Department Store
2  Distributor;Wholesaler

使用

 SELECT ID,  
 Split.a.value('.', 'VARCHAR(100)') AS String  
 FROM  (SELECT ID,  
     CAST ('<M>' + REPLACE(Question1, '; ', '</M><M>') + '</M>' AS XML) AS String  
 FROM  Registrations) AS A CROSS APPLY String.nodes ('/M') AS Split(a)

我只需要得到百货公司代理的数量

我能做点像这样的事吗

 Select Count(*),String from ( ..above query.. ) group by string ?!

您尝试的查询是正确的，它确实有效

这样做

 select count(*) as Count1,String from
    (
    SELECT ID,  
     Split.a.value('.', 'VARCHAR(100)') AS String  
     FROM  (SELECT ID,  
         CAST ('<M>' + REPLACE(Answers, ';', '</M><M>') + '</M>' AS XML) AS String  
     FROM  #t) AS A CROSS APPLY String.nodes ('/M') AS Split(a)
     )x

     group by x.String

还是像这样

select count(*) as Count1 from
        (
        SELECT ID,  
         Split.a.value('.', 'VARCHAR(100)') AS String  
         FROM  (SELECT ID,  
             CAST ('<M>' + REPLACE(Answers, ';', '</M><M>') + '</M>' AS XML) AS String  
         FROM  #t) AS A CROSS APPLY String.nodes ('/M') AS Split(a)
         )x

是的，你就是这么做的。。。您知道SQL中有多少分隔列表是正确的吗？正是出于这个原因，它们应该放在单独的表中是的，将查询放在子查询中，这样您就可以使用group by中的别名。我认为count*不需要group by，我不能把group by放在查询中：@Liath是的，它应该在一个不同的表中，有一个FK，但是像这样保存是由另一个人完成的，现在我必须处理这个问题并得到答案：如果我想替换任何包含other:xxx到other的行，我可以再添加一个替换吗

select count(*) as Count1 from
        (
        SELECT ID,  
         Split.a.value('.', 'VARCHAR(100)') AS String  
         FROM  (SELECT ID,  
             CAST ('<M>' + REPLACE(Answers, ';', '</M><M>') + '</M>' AS XML) AS String  
         FROM  #t) AS A CROSS APPLY String.nodes ('/M') AS Split(a)
         )x
