如何在SQL Server中选择行数据作为单列

Question

我在SQL Server中有一个表：

T_Id    Supplimentary_keywords
-------------------------------------------------------------------------------------------
1       Animal, Animals, 1, One, Single,live,living Organism
2       Animals, Animal, Two, 2,live,living Organism
3       Animals, Animal, Three, 3,live,living Organism
4       Animals, Animal, Four, 4,live,living Organism
5       Animals, Animal, 5, Five,live,living Organism
6       Group Of Animals, Small Group, Group, Groups, Small Size Group
7       Group Of Animals, Animals, Animal, Group, Groups, Grouping,live,living Organism
8       Group Of Animals, Animals, Animal, Group, Groups, Grouping,large Group,live 
9       Head, Heads
10      Neck, Necks

现在，我想从选择数据Supplimentary_keywords与distinct是这样的：

Supplimentary_keywords
----------------------
Animal
Animals
1
One
Single
live
living Organism
Two
2
live
Three
3
.......

我正在使用以下代码

SELECT DISTINCT
    Split.a.value('.', 'VARCHAR(100)') Kwd
FROM   
    (SELECT 
         T_Id, 
         CAST('<M>' + Replace(Supplimentary_keywords, ',', '</M><M>')
                    + '</M>' AS XML) AS Data from KWD_Theaurus_tbl) AS A
     CROSS APPLY 
         data.nodes ('/M') AS Split(a) 

并得到错误

讯息9421，第16级，状态1，第1行
XML解析：第1行，字符11，非法名称字符

如果我做错了，请帮助我如何实现这一目标或纠正我。

Answer 1

create table #temp (id int,suppl varchar(1000))
insert into #temp
select 1 ,      'Animal, Animals, 1, One, Single,live,living Organism'
union all
select 2  ,     'Animals, Animal, Two, 2,live,living Organism'
union all
select 3  ,     'Animals, Animal, Three, 3,live,living Organism'
union all
select 4  ,     'Animals, Animal, Four, 4,live,living Organism'
union all
select 5  ,     'Animals, Animal, 5, Five,live,living Organism'
union all
select 6  ,     'Group Of Animals, Small Group, Group, Groups, Small Size Group'
union all
select 7  ,     'Group Of Animals, Animals, Animal, Group, Groups, Grouping,live,living Organism'
union all
select 8  ,     'Group Of Animals, Animals, Animal, Group, Groups, Grouping,large Group,live'
union all
select 9  ,     'Head, Heads'
union all
select 10  ,    'Neck, Necks'



SELECT distinct Split.a.value('.', 'VARCHAR(100)') data
           FROM   (select id,Cast ('<M>'
                                + Replace(suppl, ',', '</M><M>')
                                + '</M>' AS XML) AS Data from #temp) AS A
                  CROSS APPLY Data.nodes ('/M') AS Split(a) 

Answer 2

尝试这个..

SELECT distinct Split.a.value('.', 'VARCHAR(100)') data
           FROM   (select id,Cast ('<M>'
                                + replace(Replace(suppl, ',', '</M><M>'),'&','&amp;')
                                + '</M>' AS XML) AS Data from #temp) AS A
                  CROSS APPLY Data.nodes ('/M') AS Split(a) 

如果您还有其他任何spl字符，请相应替换。

无效的特殊字符及其在xml中的替代

& - &
< - &lt;
> - &gt;
" - &quot;
' - &#39;

   SELECT DISTINCT Split.a.value('.', 'VARCHAR(100)') AS Supplimentary_keywords
     FROM   (SELECT id,
           Cast ('<M>'
                 + Replace(Supplimentary_keywords, ',', '</M><M>')
                 + '</M>' AS XML) AS Supplimentary_keywords
    FROM   #temp) AS A
   CROSS APPLY Supplimentary_keywords.nodes ('/M') AS Split(a);
