--如何用"最小缺失数"实现确实日期的自动补全
-->生成测试数据:

IF OBJECT_ID('TBL')IS NOT NULL
DROP TABLE TBL
GO
CREATE TABLE TBL(

GO
IF OBJECT_ID('P_SP')IS NOT NULL
DROP PROC P_SP
GO
CREATE PROC P_SP 
@STARTTIME DATE,--用来传入起始日期

DECLARE @SQL VARCHAR(100)

类似问题，刚刚写好的，给你参考一下

------解决方案--------------------
其它字段插入时怎么处理，给出输入格式

------解决方案--------------------

假如你的1到N在某个表tb1,要插入表tb2

insert into tb2 select ... from tb1 where not exists(select 1 from tb2 where tb2.关键字 = tb1.关键字)  
  
如果不存在表tb1,则可以使用系统表sysobjects来生成你的序列表.
select (select count(1) from sysobjects m where m.id < n.id) + 1 as px from sysobjects n
