在两个词之间剪切文本

Question

我只想得到这个：

000020004641,000020006307,000020001441

现在我明白了：

000020004641;1003000020006307#000020006307;1003000020001441#000020001441

我认为我必须在 ; 之间剪切文本还有这个 # 但我不知道怎么做。

你知道怎么做吗？

Answer 1

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);

Answer 2

你可以取你的字符串值

000020004641;1003000020006307#000020006307;1003000020001441#000020001441

并将分隔符替换为开始标签和结束标签

，将其更改为XML

000020004641<X>1003000020006307</X>000020006307<X>1003000020001441</X>000020001441

这是一个混合内容 XML 片段，其中您正在查看的节点值作为单独的文本节点位于根级别。

然后你可以在文本节点上切碎 XML 并使用 for xml path 技巧连接成一个字符串。

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, '');
