SQL中自定义拆分为新表的函数

 /*按照符号分割字符串*/
create function [dbo].[m_split](@c varchar(2000),@split varchar(2))
  returns @t table(col varchar(200))
  as
    begin
      while(charindex(@split,@c)<>0)
        begin
          insert @t(col) values (substring(@c,1,charindex(@split,@c)-1))
            set @c = stuff(@c,1,charindex(@split,@c),'')
           -- SET @c = substring(@c,charindex(' ',@c)+1,len(@c))
        end
      insert @t(col) values (@c)
      return
end

select * from dbo.m_split('1,2,3,4,5',',')
