預存程序中拆分字串的方法

一、程式片段：
declare @tempstr varchar(100)
set @tempstr='1,3,4,5,447,8,10'
declare @tempi intselect @tempstr=@tempstr+','
select @tempi=charindex(',',@tempstr)
while  @tempi<>0
begin
   print left(@tempstr,@tempi-1)
   select @tempstr=substring(@tempstr,@tempi+1,len(@tempstr) - @tempi)
   select @tempi=charindex(',',@tempstr)
end

二、函數：
/*
功能：實現split功能的函數
*/create function fn_split
(
@inputstr varchar(8000),
@seprator varchar(10)
)
returns @temp table (a varchar(200))
as begin
declare @i intset @inputstr = rtrim(ltrim(@inputstr))
set @i = charindex(@seprator, @inputstr)while @i >= 1
begin
insert @temp values(left(@inputstr, @i - 1))set @inputstr = substring(@inputstr, @i + 1, len(@inputstr) - @i)
set @i = charindex(@seprator, @inputstr)
endif @inputstr <> '/'
insert @temp values(@inputstr)return
end用法：select * from dbo.f_split(ABC:BC:C:D:E,:)
