分割分号分隔符SQL到行 [英] split semicolon delimiter SQL to rows

问题描述

只是想要求帮助。
我试图用分号作为分隔符拆分分隔的值。
逗号不能替换为分号，因为值有逗号。

Just want to ask for help. I'm trying to split delimited values with a semicolon as a delimiter. Comma cannot be replaced to the semicolon since there are values that have comma.

ID   Value
1   | A&B;C;D;E, F

转换为：

ID   Value
1    A&B
1    C
1    D
1    E, F

我尝试调整我在线但无法成功的SQL脚本

I tried tweaking the SQL scripts that i got online but to no success

SELECT F1.ID,
 O.splitdata 
FROM
 (
 SELECT OldID,
 cast('<X>'+replace((SELECT ColumnName + '' FOR XML PATH('')),';','</X><X>')+'</X>' as XML) as xmlfilter from TableName F
 )F1
 CROSS APPLY
 ( 
 SELECT fdata.D.value('.','varchar(max)') as splitdata 
 FROM f1.xmlfilter.nodes('X') as fdata(D)) O

我的一些列，但如果列有特殊或非法字符，它会输出此错误：

It works for some of my columns but if the columns have special or Illegal characters it outputs this error:

Msg 9411, Level 16, State 1, Line 2
XML parsing: line 1, character 16, semicolon expected

谢谢！ / p>

Thanks!

推荐答案

如果您不喜欢某个功能，或者您没有创建新功能的权限，可以使用相当快的XML方法。在你的情况下，它需要一些额外的努力来获得这个XML安全（由于特殊字符和; 作为分隔符）：

If you do not like a function, or if you do not have the rights to create a new function, you can use the quite fast XML approach. In your case it needs some extra effort to get this XML-safe (due to special characters and the ; as delimiter):

Declare @Dummy table (ID int, SomeTextToSplit varchar(max))
Insert Into @Dummy values
 (1,'A&B;C;D;E, F')
,(2,'"C" & "D";<C>;D;E, F');

DECLARE @Delimiter VARCHAR(10)=';';
WITH Casted AS
(
    SELECT *
          ,CAST('<x>' + REPLACE((SELECT REPLACE(SomeTextToSplit,@Delimiter,'§§Split$me$here§§') AS [*] FOR XML PATH('')),'§§Split$me$here§§','</x><x>') + '</x>' AS XML) AS SplitMe
    FROM @Dummy
)
SELECT Casted.*
      ,x.value('.','nvarchar(max)') AS Part 
FROM Casted
CROSS APPLY SplitMe.nodes('/x') AS A(x)

结果

1   A&B
1   C
1   D
1   E, F
2   "C" & "D"
2   <C>
2   D
2   E, F
