SqlServer 创建数据库 使用多个文件组和物理磁盘

现在服务器的瓶颈主要是15000转的硬盘无法满足日益增长的I/O需求，这时创建数据库时要尽量将数据库的I/O压力分解到多个磁盘中。

use mastergoif DB_ID(N'care365') is not null--如果数据库存在，则删除它drop database care365gocreate database care365on primary(name=care1,filename='C:/database/care365.mdf',--主文件组放在C盘下size=10MB,filegrowth=15%),filegroup caregroup1(name=care2,filename='D:/database/care365_group1.ndf',--在D盘上创建一个文件组size=10MB,filegrowth=15%),filegroup caregroup2--该文件组分布在D和E两个盘符下(name=care3,filename='D:/database/care365_group2.ndf',size=10MB,filegrowth=15%),(name=care4,filename='E:/database/care365_group2.ndf',size=10MB,filegrowth=15%)log on(name=care_log,filename='c:/database/care365.ldf',--将日志文件放到C盘下size=10MB,filegrowth=15%)go

数据库创建好之后，由于是实验用，设置自动关闭，节约资源

alter database care365set auto_close ongo

添加数据库中的表和实验数据
