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 master go if DB_ID(N'care365') is not null--如果数据库存在，则删除它 drop database care365 go create database care365 on 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,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,( name=care4,filename='E:/database/care365_group2.ndf',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 care365 set auto_close on go

添加数据库中的表和实验数据

use care365 go if OBJECT_ID(N'Customer') is not null drop table dbo.customer go create table dbo.Customer ( ID UNIQUEIDENTIFIER ROWGUIDCOL PRIMARY KEY NOT NULL CONSTRAINT DF_Customer_id DEFAULT (NEWSEQUENTIALID()),Name nvarchar(50) not null,number nvarchar(50) not null constraint DF_Student_Number default (N'无') ) on caregroup1; go insert dbo.Customer (Name,number) values (N'张三',N'001') insert dbo.Customer (Name,number) values (N'李四',N'002') insert dbo.Customer (Name,number) values (N'王五',N'003') insert dbo.Customer (Name,number) values (N'赵六',N'004') go select * from dbo.Customer if OBJECT_ID(N'Product') is not null drop table dbo.Product go create table dbo.Product ( ID UNIQUEIDENTIFIER ROWGUIDCOL PRIMARY KEY NOT NULL CONSTRAINT DF_Product_id DEFAULT (NEWSEQUENTIALID()),Name nvarchar(512) not null,Code nvarchar(50) not null constraint DF_Product_Code default (N'无'),Price money not null constraint DF_product_price default ((0)) ) on caregroup1 go insert dbo.Product (Name,Code,Price) values (N'奥迪 A4L 2010款 3.2FSI quattro 旗舰型',N'Audi_A4L_3.2FSI_quattro',57.81*10000) insert dbo.Product (Name,Price) values (N'奥迪 A6L 2010款 3.0TFSI quattro 豪华型',N'Audi_A6L_3.0TFSI_quattro',69.60*10000) insert dbo.Product (Name,Price) values (N'奥迪 A8L 2009款 6.0L quattro 专享尊崇型',N'Audi_A8L_6.0_quattro',291*10000) insert dbo.Product (Name,Price) values (N'奥迪 Q5 2010款 2.0TFSI 豪华型',N'Audi_Q5_2.0TFSI',60.39*10000) insert dbo.Product (Name,Price) values (N'奥迪 Q7 2010款 4.2FSI quattro 豪华型',N'Audi_Q7_4.2FSI_quattro',145*10000) go select * from dbo.Product if OBJECT_ID(N'Orders') is not null drop table dbo.Orders go create table dbo.Orders ( ID UNIQUEIDENTIFIER ROWGUIDCOL PRIMARY KEY NOT NULL CONSTRAINT DF_Orders_id DEFAULT (NEWSEQUENTIALID()),CreateTime datetime not null constraint DF_Orders_CreateTime default(getdate()),CustomerID UNIQUEIDENTIFIER not null ) on caregroup2 go insert dbo.Orders (CustomerID) values ('00AC9FF3-348C-DF11-A98B-001E37DA94AB') insert dbo.Orders (CustomerID) values ('01AC9FF3-348C-DF11-A98B-001E37DA94AB') insert dbo.Orders (CustomerID) values ('02AC9FF3-348C-DF11-A98B-001E37DA94AB') insert dbo.Orders (CustomerID) values ('03AC9FF3-348C-DF11-A98B-001E37DA94AB') go select * from dbo.Orders if OBJECT_ID(N'OrderInfo') is not null drop table dbo.OrderInfo go create table dbo.OrderInfo ( ID UNIQUEIDENTIFIER ROWGUIDCOL PRIMARY KEY NOT NULL CONSTRAINT DF_OrderInfo_id DEFAULT (NEWSEQUENTIALID()),OrdersID UNIQUEIDENTIFIER not null,ProductID UNIQUEIDENTIFIER not null,Price money not null constraint DF_OrderInfo_Price default ((0)),Quantity int not null constraint DF_OrderInfo_Quantity default((0)) ) on caregroup2 go insert dbo.OrderInfo (OrdersID,ProductID,Price,Quantity) values ('0A2E2E09-AA8C-DF11-9EB4-001E37DA94AB','0AF16B9C-A28C-DF11-9EB4-001E37DA94AB',578100.00,1) insert dbo.OrderInfo (OrdersID,Quantity) values ('0B2E2E09-AA8C-DF11-9EB4-001E37DA94AB','0BF16B9C-A28C-DF11-9EB4-001E37DA94AB',696000.00,Quantity) values ('0C2E2E09-AA8C-DF11-9EB4-001E37DA94AB','0CF16B9C-A28C-DF11-9EB4-001E37DA94AB',2910000.00,Quantity) values ('0D2E2E09-AA8C-DF11-9EB4-001E37DA94AB','0DF16B9C-A28C-DF11-9EB4-001E37DA94AB',603900.00,'0EF16B9C-A28C-DF11-9EB4-001E37DA94AB',1450000.00,1) go select * from dbo.OrderInfo
