如何在SQLServer2008中使用存储过程拆分字符串并将数据插入表

我想拆分此格式的字符串 引述：

。

实际上这个字符串只是一个示例，我的原始字符串非常大。我没有得到一点，如果我打断这个字符串，那么在拆分字符串之后，我需要多少变量来捕获数据，我希望这些变量被插入到包含日期和年龄等列的数据表中？我使用什么概念？（我从web服务获得这个字符串）提前感谢..

一般来说，我建议编写一个CLR函数，通过正则表达式或SQL表值函数拆分字符串，但在您的情况下，您可以尝试一些简单的方法，例如将字符串转换为xml并对其进行解析：

declare @str nvarchar(max) = 'date=10/10/2000|age=13^date=01/01/2001|age=12^date=02/02/2005|age=8'
declare @data xml

select @str = replace(@str, '=', '="')
select @str = replace(@str, '|', '" ')
select @str = replace(@str, '^', '"/><row ')
select @str = '<row ' + @str + '"/>'

select @data = cast(@str as xml)

select
    t.c.value('@date', 'nvarchar(max)') as [date],
    t.c.value('@age', 'nvarchar(max)') as [age]
from @data.nodes('row') as t(c)

declare@str nvarchar（max）='date=10/10/2000 | age=13^ date=01/01/2001 | age=12^ date=02/02/2005 | age=8'
声明@dataxml
选择@str=replace（@str，“=”，“=”）
选择@str=replace（@str，|，“，”）
选择@str=replace（@str，'^'，'“/>试试这个：

Declare @stringToSplit varchar(max)='date=10/10/2000|age=13^date=01/01/2001|age=12^date=02/02/2005|age=8^date=10/10/2000|age=13^date=01/01/2001|age=12^date=02/02/2005|age=8^date=10/10/2000|age=13^date=01/01/2001|age=12^date=02/02/2005|age=8^date=10/10/2000|age=13^date=01/01/2001|age=12^date=02/02/2005|age=8'

DECLARE @YourTable table (RowID int, Layout varchar(max))
INSERT @YourTable VALUES (1,@stringToSplit)

;WITH SplitSting AS
(
    SELECT
    RowID,LEFT(Layout,CHARINDEX('^',Layout)-1) AS Part
   ,RIGHT(Layout,LEN(Layout)-CHARINDEX('^',Layout)) AS Remainder
    FROM @YourTable
    WHERE Layout IS NOT NULL AND CHARINDEX('^',Layout)>0
    UNION ALL
    SELECT
    RowID,LEFT(Remainder,CHARINDEX('^',Remainder)-1)
   ,RIGHT(Remainder,LEN(Remainder)-CHARINDEX('^',Remainder))
    FROM SplitSting
    WHERE Remainder IS NOT NULL AND CHARINDEX('^',Remainder)>0
    UNION ALL
    SELECT
    RowID,Remainder,null
    FROM SplitSting
    WHERE Remainder IS NOT NULL AND CHARINDEX('^',Remainder)=0

)

select SUBSTRING(part,CHARINDEX('=',part)+1,(CHARINDEX('|',part)-CHARINDEX('=',part))-1) as [Date],RIGHT(part,CHARINDEX('=',reverse(part))-1) as [Age] from SplitSting

只是一个建议-在web/controller上捕获字符串，为您的数据编写一个解析器，即一个具有日期、年龄或其他属性的对象，创建此对象的集合，并使用批量插入到db。此外，字符串来自web服务-是否有任何方式可以格式化为JSon对象-嘿，让我们保持它非常简单，不需要J据我所知…当然-取决于您对web服务和功能请求的访问Hank u…真的很好！您好，但它给出的错误为“MSG 9410，16级，状态1，第11行XML解析：第1行，字符20964，预期为空白“。你能提供字符串以便我测试它吗？我无法将其发送给你…远远超出了评论框的容量…我告诉你一件事，字符串包含25000个字符。你能将字符串按块分割，看看问题出在哪里吗？”？
