Question

我有3个存储过程参数，如

@String1 varchar(100) = 'a,b,c';
@String2 Varchar(100) = '1,2,3';
@String3 Varchar(100) = 'x,y,z';

我需要拆分这些数据并将其作为

插入到表中

column1   column2  column3
-------  -------- ----------
  a         1         x
  b         2         y
  c         3         z

我已经有一个函数将分离的sting分成结果集（见下文）

create function [dbo].[SplitStringToResultSet] (@value varchar(max), @separator char(1))
returns table
as return
with r as (
    select value, cast(null as varchar(max)) [x], 0 [no] from (select rtrim(cast(@value as varchar(max))) [value]) as j
    union all
    select right(value, len(value)-case charindex(@separator, value) when 0 then len(value) else charindex(@separator, value) end) [value]
    , left(r.[value], case charindex(@separator, r.value) when 0 then len(r.value) else abs(charindex(@separator, r.[value])-1) end ) [x]
    , [no] + 1 [no]
    from r where value > '')

select x [value], [no] from r where x is not null

使用此功能可以解决您的问题，例如：

select n1.value [column1], n2.value [column2], n3.value [column3]
from [dbo].[SplitStringToResultSet] ('a,b,c', ',') n1
join [dbo].[SplitStringToResultSet] ('1,2,3', ',') n2 on n1.[no] = n2.[no]
join [dbo].[SplitStringToResultSet] ('x,y,z', ',') n3 on n1.[no] = n3.[no]

结果

column1 column2 column3
a       1       x
b       2       y
c       3       z

我想拆分一个字符串并将数据插入SQL Server 2005表
