declare @arr varchar(max)
declare @people varchar(100)
declare @find int

--要拆分的字符串数组，逗号分隔
set @arr='AA,BB,CC,DD'
set @find=1

while  @find>0
begin 
set @find=charindex(',',@arr)
set @people=SUBSTRING(@arr,1,@find-1)

--print 'find='+convert(varchar(100),@find)
--print convert(varchar(100),@find)+ @people
   print @people

  --查找敏感词
   select @people,[id],[content],[createtime] from [Bus_InformationInfo] a    
   where [Content] like '%'+@people+'%'

set @arr=SUBSTRING(@arr,@find+1,10000)
-- print 'arr:'+ @arr

 if LEN(@arr)=0
 begin
   -- 退出循环 
   break
 end

	if charindex(',',@arr)=0
	begin
	  --最后一个词
	   set @arr=@arr+','	 
	end
end
