SQL存储过程高效分割传入字符串方法！求更好的、更高效的方法！！！！！！！！

SQL code

declare @next int declare @ArrayLen intdeclare @errorSun intset @errorSun=0 BEGIN TRANSACTION--开始事务set @ArrayLen=dbo.Get_StrArrayLength(@DFXStr,'$') set @next=1 while @next<=@ArrayLen-2   beginif(@Step=1)update DFXCompSpread set RDFeedback=dbo.Get_StrArrayStrOfIndex(@DFXStr,'$',@next+2),rdchange=dbo.Get_StrArrayStrOfIndex(@DFXStr,'$',@next+1) where  DFXCSID=dbo.Get_StrArrayStrOfIndex(@DFXStr,'$',@next)elseupdate DFXCompSpread set DFXComComment=dbo.Get_StrArrayStrOfIndex(@DFXStr,'$',@next+2), DFMChange=dbo.Get_StrArrayStrOfIndex(@DFXStr,'$',@next+1) where  DFXCSID=dbo.Get_StrArrayStrOfIndex(@DFXStr,'$',@next)

用 dbo.Get_StrArrayLength 发现字符串长了，更新起来特别慢，贴个串：

谁有更好的sql分割串的方法！！！！！！！！求教！！！！！！

不是分割慢.而是你循环需修改慢..

dbo.Get_StrArrayLength 干什么用？
求字符串长度可以用 LEN(字符串) 来获取
------解决方案--------------------------------------------------------

SQL code

CREATE  function dbo.f_splitstr(     @SourceSql varchar(8000),     @StrSeprate varchar(10)   )returns @temp table(F1 varchar(200))   as  begin    declare @i int     set @SourceSql=rtrim(ltrim(@SourceSql))      set @i=charindex(@StrSeprate,@SourceSql)      while @i>=1      begin       insert @temp values(left(@SourceSql,@i-1))        set @SourceSql=substring(@SourceSql,@i+1,len(@SourceSql)-@i)        set @i=charindex(@StrSeprate,@SourceSql)      end     if @SourceSql<>''       insert @temp values(@SourceSql)      returnend

靠  3 4 5 楼呢？
------解决方案--------------------------------------------------------
是吗？呵呵……
------解决方案--------------------------------------------------------
SQL code--创建函数: CREATE   function   [dbo].[SplitStr] (     @SourceSql   varchar(8000),     @StrSeprate   varchar(100))     returns   @temp   table(F1   varchar(100) )      as        begin      declare   @ch   as   varchar(100)      set   @SourceSql=@SourceSql+@StrSeprate        while(@SourceSql<>'')                      begin                      set   @ch=left(@SourceSql,charindex(',',@SourceSql,1)-1)      insert   @temp   values(@ch)      set   @SourceSql=stuff(@SourceSql,1,charindex(',',@SourceSql,1),'')                      end     return      end --应用(存储过程)： CREATE PROCEDURE [dbo].[UP_Student_GetListByStatus]     @StatusList varchar(max) AS  SELECT [Student].* FROM Student  WHERE      [Student].[PK_Status] IN (SELECT F1 FROM dbo.SplitStr(@StatusList,','))
