1.复制表(只复制结构, 源表名a,新表名b)
select * into b from a where 1<>1
2.拷贝表(拷贝数据,源表名a,目标表名b)
inert into b(a,b,c) select d,e,f from b
3.两张关联表,删除主表中已经在副表中没有的信息
delete from info where not exists (select * from infobz where
info.infid=infobz.infoid)
4.建表,批量插入数据
create table a(aid varchar(8),adate datetime)
go
insert into a
select '5911','2920-1-1'
union all select '5988','2800-12-24'
union all select '5988','2600-12-24'
union all select '5988','2500-12-24'
union all select '5988','2100-12-24'
union all select '5988','2099-12-24'
5.分页的
pagesize :每页显示的记录数
currentpage: 当前页号
数据表的名称: components
索引主键: id
select top pagesize * from components
where id not in
(select top (pagesize*(currentpage-1)) )
select * into b from a where 1<>1
