双重循环sql操作

双重循环sql操作(二个变量@UserID,@RightID,@Max为@UserID的最大值)
declare @UserID int,@Max int,@RightID int
set @UserID=(select top 1 UserID  from [sys_UserRight] order by userid asc)
set @Max=(select top 1 UserID  from [sys_UserRight] order by userid desc)
while @UserID< =@Max
     begin
     set @RightID='1119'
            while @RightID in ('1211','1212','1119')
               begin
                    INSERT INTO [sys_UserRight] ([UserID] ,[RightID])
                    VALUES (@UserID,@RightID)
                    set @RightID=@RightID+1
                end
            set @UserID=@UserID+1 
            while  @UserID not in (select distinct(UserID) from [sys_UserRight]) and @UserID<@Max+1--循环检索@UserID是否存在
   begin 
                       set  @UserID=@UserID+1
                 end
     end
