请教数据插入的优化
例如说我要给给数据库插入数据(日期字段),从 "2001-1-1 "到 "2100-1-1 "(按月递增),那么我是不是只能通过循环,逐个插入呢?有没有更好的方法呢?(现在要INSERT 1200次)
------解决方案--------------------create table test(months datetime)
go
set rowcount 1200
select identity(int,0,1) as id into # from sysobjects a,sysobjects b
set rowcount 0
insert into test(months)
select dateadd(m,id, '2001-01-01 ') from #
select * from test
go
drop table test,#
go
------解决方案--------------------set rowcount 1000000
select identity(int,0,1) as id into # from sysobjects a,sysobjects b, syscolumns c, syscolumns d
set rowcount 0
