Split函数(SQL Server)


-- 建立函数
create function dbo.fn_split
(
 @originalString nvarchar(200),
 @splitter nvarchar(1)
)
returns @temp table
(
 id int identity(1, 1) primary key,
 value nvarchar(100)
)
as
begin
    declare @i int, @tempString varchar(100) 

    set @originalString=rtrim(ltrim(@originalString))
    set @i=charindex(@splitter, @originalString )

 while @i > 0 
  begin
   set @tempString=left(@originalString, @i-1)

   if(len(@tempString)=1)
    set @tempString='00'+ @tempString

   if(len(@tempString)=2)
    set @tempString='0'+ @tempString

   insert @temp values(@tempString)

   set @originalString=substring(@originalString, @i+1, len(@originalString)-@i)
   set @i=charindex(@splitter, @originalString )   
  end

 if @originalString <> ''
  insert into @temp(value) values (@originalString)

    return
end
