我只想得到这个:
000020004641,000020006307,000020001441
现在我明白了:
000020004641;1003000020006307#000020006307;1003000020001441#000020001441
在我看来,我必须在两者之间剪切文字; #这个#但我不知道怎么做。
你知道怎么做吗?

示例查询:
DECLARE @text VARCHAR(150) = '000020004641;1003000020006307#000020006307;1003000020001441#000020001441'
;WITH CTE AS
(
--initial part
SELECT 1 AS MyCounter, LEFT(REPLACE(@text, '#', ';'), CHARINDEX(';',REPLACE(@text, '#', ';'))-1) AS MyText,
RIGHT(REPLACE(@text, '#', ';'), LEN(REPLACE(@text, '#', ';')) - CHARINDEX(';',REPLACE(@text, '#', ';'))) AS Remainder
WHERE CHARINDEX(';',REPLACE(@text, '#', ';'))>0
--recursive part
UNION ALL
SELECT MyCounter +1 AS MyCounter, LEFT(Remainder, CHARINDEX(';',Remainder)-1) AS MyText,
RIGHT(Remainder, LEN(Remainder) - CHARINDEX(';',Remainder)) AS Remainder
FROM CTE
WHERE CHARINDEX(';',Remainder)>0
UNION ALL
SELECT MyCounter +1 AS MyCounter, Remainder AS MyText, NULL AS Remainder
FROM CTE
WHERE CHARINDEX(';',Remainder)=0
)
SELECT *
FROM CTE
结果:
MyCounter MyText Remainder
1 000020004641 1003000020006307;000020006307;1003000020001441;000020001441
2 1003000020006307 000020006307;1003000020001441;000020001441
3 000020006307 1003000020001441;000020001441
4 1003000020001441 000020001441
5 000020001441 NULL

您是MVC开发人员。所以,我的下一个建议是使用Linq:
string aText = @"000020004641;1003000020006307#000020006307;1003000020001441#000020001441";
var qry = aText.Split(new char[]{';','#'}).Select(x=>x);

您可以使用字符串值
000020004641;1003000020006307#000020006307;1003000020001441#000020001441
并将分隔符替换为带有开始标记和结束标记的分隔符
,将其更改为XML000020004641<X>1003000020006307</X>000020006307<X>1003000020001441</X>000020001441
这是一个混合内容XML片段,其中您正在查找的节点值位于根级别的单独文本节点上。
然后你可以在文本节点上粉碎XML并使用for xml path
技巧连接到一个字符串。
declare @S varchar(100) = '000020004641;1003000020006307#000020006307;1003000020001441#000020001441';
set @S = replace(@S, ';', '<X>');
set @S = replace(@S, '#', '</X>');
declare @X xml = cast(@S as xml);
select stuff((
select ','+T.X.value('.', 'varchar(100)')
from @X.nodes('text()') as T(X)
for xml path('')
), 1, 1, '');
