数据库和表的创建与管理.docx

数据库原理实验报告题目：实验一数据库和表的创建与管理学号姓名班级日期2016/10/11一 实验内容、步骤以及结果1.利用图形用户界面创建，备份，删除和还原数据库和数据表(1)创建SPJ数据库，初始大小为 10MB，最大为50MB，数据库自动增长，增长方式是按5比例增长；日志文件初始为2MB，最大可增长到5MB，按1MB增长。数据库的逻辑文件名和物理文件名均采用默认值。(2)在SPJ数据库中创建如图2.1-图2.4的四张表(只输入一部分数据示意即可)(3)备份数据库SPJ（第一种方法)：备份成一个扩展名为bak的文件。(4)备份数据库SPJ（第二种方法)：将SPJ数据库定义时使用的文件(扩展名为mdf,ldf的数据文件、日志文件等)复制到其他文件夹进行备份。(5)删除已经创建的工程项目表(J表)。(6)删除SPJ数据库。(7)利用备份过的bak备份文件还原刚才删除的SPJ数据库。(8)利用备份过的mdf,ldf的备份文件还原刚才删除的SPJ数据库。(9)将SPJ数据库的文件大小修改为100MB。(10)修改S表，增加一个联系电话的字段sPhoneNo，数据类型为字符串类型。2.利用SQL语言创建和删除数据库和数据表(1) 用SQL语句创建如图2.5-图2.7要求的数据库Student， 初始大小为20MB，最大为100MB，数据库自动增长，增长方式是按10M兆字节增长；日志文件初始为2MB，最大可增长到5MB，按1MB增长。数据库的逻辑文件名和物理文件名，日志文件名请自定义。USE masterGOCREATE DATABASE Student ON PRIMARY (NAME = Student, FILENAME = c:Program FilesMicrosoft SQL ServerMSSQL10_50.SQLEXPRESSMSSQLDATAStudent.mdf , SIZE = 20480KB , MAXSIZE = 102400KB , FILEGROWTH = 10240KB )LOG ON (NAME = Student_log, FILENAME = c:Program FilesMicrosoft SQL ServerMSSQL10_50.SQLEXPRESSMSSQLDATAStudent_log.ldf , SIZE = 1024KB , MAXSIZE = 5120KB , FILEGROWTH = 1024KB )GO(2) 用SQL语句创建上述的三张表，各个字段的数据类型请自己确定，每张表只要有主键约束即可，不要其他约束。不用输入数据。USE StudentGO-创建S表，C表，SC表-2016/10/10CREATE TABLE dbo.S( -建s表sno char(5),sname char(6),ssex char(2),sbirth char(10),sdept char (2)ON PRIMARYCREATE TABLE dbo.C(-建C表cno int,cname char(10),cpno int,ccredit int)ON PRIMARYCREATE TABLE dbo.SC(-建SC表sno char(5),cno int,grade int)ON PRIMARYGO(3) 用SQL中的backup 语句将数据库Student备份到一个bak文件。(提示：backup database student to disk)USE Student GO-备份数据库BACKUP DATABASE Student TO disk=c:实验一Student.bak;(4) 用SQL语句删除创建的表。USE Student GO-删除C表DROP TABLE dbo.C;(5) 将Student数据库定义时使用的文件(扩展名为mdf,ldf的数据文件、日志文件等)复制到其他文件夹进行备份（复制）后，用SQL语句删除创建的数据库。USE StudentGO-删除数据库DROP DATABASE Student;(6) 用SQL中的sp_attache_db语句完成对数据库Student的附加。（通过该方式完成数据库的恢复时，使用的备份文件是第5）小题中备份好的数据文件、日志文件等 ，具体用法：exec sp_attache_db )USE master GO-数据库附加sp_attach_single_file_db dbname = Student, physname = H:实验一Student.mdf;(7) 先删除Student库，再用SQL中的restore 语句还原刚才备份的数据库Student。 （提示：restore database student from disk）USE masterGO -还原数据库RESTORE DATABASE Student FROM DISK= C:实验一Student.bak;GO(8) 用SQL语言修改数据库Student，给Student数据库添加一个文件组 TestFG1，然后将两个 5 MB 的文件添加到该文件组。(提示：alter database)USE masterGOALTER DATABASE StudentADD FILEGROUP Test1FG1;GOALTER DATABASE Student ADD FILE ( NAME = test1dat3, FILENAME=C:ProgramFilesMicrosoftSQLServerMSSQL10_50.SQLEXPRESSMSSQLDATAt1dat3.ndf, SIZE = 5MB, MAXSIZE = 100MB, FILEGROWTH = 5MB),( NAME = test1dat4, FILENAME=C:ProgramFilesMicrosoftSQLServerMSSQL10_50.SQLEXPRESSMSSQLDATAt1dat4.ndf, SIZE = 5MB, MAXSIZE = 100MB, FILEGROWTH = 5MB)TO FILEGROUP Test1FG1;GO (9) 修改S表，增加一个表示联系电话的字段sPhoneNo，数据类型为字符串类型。USE StudentGO ALTER TABLE dbo.S ADDsPhoneNo nchar(11) NULLGO(10) 利用SQL Server Management Studio的生成脚本功能(选中Student库-右键菜单“任务”- “生成脚本”)，自动生成S表的创建脚本，分析自动生成的脚本和自己写的SQL语句的异同点。USE masterGO/* Object: Database
