1. CREATE DATABASE database_name [ON [PRIMARY] [( [ NAME = logical_file_name,] [ FILENAME = ‘ os_file_name’] [, SIZE = size] [, MAXSIZE = {max_size|UNLIMITED}] [, FILEGROWTH = growth_increment ] ) [1,... n] ] [, FILEGROUP filegroup_name [1,... n]] ] [LOG ON ( [ NAME = logical_file_name,] [ FILENAME = ‘ os_file_name’] [, SIZE = size] [, MAXSIZE = {max_size|UNLIMITED}] [, FILEGROWTH = growth_increment ] )[1,...n] ]

3. CREATE DATABASE Report ON PRIMARY (NAME = ‘Rep1_dat’, FILENAME = ‘c:\program files\microsoft sql server\mssql\data\rep1_dat.mdf’ SIZE = 5MB, MAXSIZE = 10MB, FILEGROWTH = 1MB), (NAME = ‘Rep2_dat’, FILENAME = ‘c:\program files\microsoft sql server\mssql\data\rep2_dat.ndf’ SIZE = 5MB, MAXSIZE = 10MB, FILEGROWTH = 1MB), (NAME = ‘Rep3_dat’, FILENAME = ‘c:\program files\microsoft sql server\mssql\data\rep3_dat.ndf’ SIZE = 5MB, MAXSIZE = 10MB, FILEGROWTH = 1MB) 创建一个名为 Report 的 数据库. 要求 : 一个主文件, 两个二 级文件和两个日志文件. 主数据文件的逻辑名为 Rep1_dat, 磁盘文件名为 rep1_dat.mdf 二级文件的逻辑名分别 为 Rep2_dat, Rep3_dat 磁盘文件名分别为 rep2_dat.ndf rep3_dat.ndf 事务日志文件的逻辑文 件名分别为 Rep1_log, Rep2_log, 磁盘文件名分别为 rep2_dat.ldf rep3_dat.ldf 初始容量为 5MB, 最大容 量为 10MB, 每次增长量 为 1MB.

4. LOG ON (NAME = Rep1_log, FILENAME = ‘c:\program files\microsoft sql server\mssql\data\rep1_log.ldf’ SIZE = 5MB, MAXSIZE = 10MB, FILEGROWTH = 1MB), (NAME = Rep2_log, FILENAME = ‘c:\program files\microsoft sql server\mssql\data\rep2_log.ldf’ SIZE = 5MB, MAXSIZE = 10MB, FILEGROWTH = 1MB)

5. ALTER DATABASE database { ADD FILE [,... n] [ TO FILEGROUP filegroup_name] |ADD LOG FILE [,... n] |REMOVE FILE logical_file_name |ADD FILEGROUP filegroup_name |REMOVE FILEGROUP filegroup_name |MODIFY FILE |MODIFY FILEGROUP file_group_name filegroup_property } : : = ( NAME = logical_file_name [, FILENAME = ‘os_file_name’] [, SIZE = size] [, MAXSIZE = {max_size|UNLIMITED}] [, FILEGROWTH = growth_increment] )

6. 例 DROP DATABASE Temp CREATE DATABASE Temp ON ( NAME = 'Temp1_dat', FILENAME = 'c:\program files\microsoft sql server\mssql\data\temp1_dat.mdf', SIZE = 5MB, MAXSIZE = 15MB, FILEGROWTH = 1 ) LOG ON ( NAME = 'Temp1_log', FILENAME = 'c:\program files\microsoft sql server\mssql\data\temp1_log.ldf', SIZE = 5MB, MAXSIZE = 15MB, FILEGROWTH = 1 )

7. 在上面的数据库的基础上, 向库中添加一个数据 文件和一个日志文件, 数据文件的逻辑名和实际 文件名分别为 :Temp2_dat 和 Temp2_dat.ndf, 日 志文件的逻辑名和实际文件名分为 :Temp2_log 和 Temp2_log.ldf 这几个文件的初始容量, 最大容量及文件大小递 增量相同

8. ALTER DATABASE Temp ADD FILE ( NAME = 'Temp2_dat', FILENAME = 'c:\program files\microsoft sql server\mssql\data\temp2_dat.ndf', SIZE = 5MB, MAXSIZE = 15MB, FILEGROWTH = 1 ) ALTER DATABASE Temp ADD LOG FILE ( NAME = 'Temp2_log', FILENAME = 'c:\program files\microsoft sql server\mssql\data\temp2_log.ldf', SIZE = 5MB, MAXSIZE = 15MB, FILEGROWTH = 1 )

9. ALTER DATABASE Temp MODIFY FILE ( NAME = Temp1_dat, SIZE = 10, MAXSIZE = 20, FILEGROWTH = 2 ) 将前面的数据库中的数据文件 Temp1_dat 的容 量增加到 10MB, 并将其容量最大值增加到 20MB, 递增量增加到 2MB.

10. ALTER DATABASE Temp ADD FILEGROUP TempFileGroup ALTER DATABASE Temp ADD FILE ( NAME = 'Temp3_dat', FILENAME = 'c:\program files\microsoft sql server\mssql\data\temp3_dat.ndf', SIZE = 3, MAXSIZE = 10, FILEGROWTH = 1 ), ( NAME = 'Temp4_dat', FILENAME = 'c:\program files\microsoft sql server\mssql\data\temp4_dat.ndf', SIZE = 3, MAXSIZE = 10, FILEGROWTH = 1 ) TO FILEGROUP TempFileGroup ALTER DATABASE Temp REMOVE FILE Temp2_log

11. DROP DATABASE 产品数据库, 员工数据库 例 : 同时删除 产品数据库 和 员工数据库 删除数据库 DROP DATABASE database_name[,…..n]

12. CREATE TABLE 语句创表的语法如下： CREATE TABLE [ database_name.[ owner ].| owner.] table_name ( { column_name data_type | column_name AS computed_column_expression | } [,...n ] ) [ ON { filegroup | DEFAULT } ] [ [ DEFAULT constant_expression ] | [ IDENTITY [ ( seed, increment ) ] ] ] [ ] [...n ]

13. CREATE TABLE project ( 项目编号 int CONSTRAINT PK_Pno PRIMARY KEY, 项目名称 varchar(40) ) CREATE TABLE project ( 项目编号 int PRIMARY KEY, 项目名称 varchar(40) )

14. CREATE TABLE project ( 项目编号 int, 项目名称 varchar(40), CONSTRAINT PK_Pno_Pname PRIMARY KEY( 项目编号, 项目名称 ) ) CREATE TABLE project ( 项目编号 int CONSTRAINT PK_Pno PRIMARY KEY, 项目名称 char(20) CONSTRAINT UN_Pname UNIQUE )

15. CREATE TABLE project ( 项目编号 int PRIMARY KEY, 项目名称 char(20) UNIQUE ) CREATE TABLE project ( 项目编号 int CONSTRAINT PK_Pno PRIMARY KEY, 项目名称 char(20), 项目负责人 char(20), CONSTRAINT UN_Pname_Pm UNIQUE( 项目名称, 项目负责人 ) )

16. CREATE TABLE employees ( 员工编号 int PRIMARY KEY, 员工姓名 char(20) UNIQUE ) GO 创建数据表 employees, 包括员工编号和员工姓名两个字段， 其中员工编号为主键，员工姓名为唯一键。

17. -- 创建数据表 project CREATE TABLE project ( 项目编号 int PRIMARY KEY, 项目名称 char(20), 项目负责人 char(20) FOREIGN KEY REFERENCES temp9( 员工姓名 ) ON DELETE CASCADE ) GO

18. CREATE TABLE employees ( 员工编号 int NOT NULL PRIMARY KEY, 员工姓名 char(20) UNIQUE, 工资 int NOT NULL CONSTRAINT CK_Es CHECK ( 工资 >= 1000 AND 工资 <= 20000) ) 创建核查约束

19. CREATE TABLE employees ( 员工编号 int NOT NULL PRIMARY KEY, 员工姓名 char(20), 工资 int NOT NULL ） CREATE RULE RU_salary AS @salary>=1000 AND @salary <=20000 GO EXEC sp_bindrule ‘RU_salary’, ‘employee. 工资 ’ GO 创建规则

20. CREATE DEFAULT DE_salary as 1000 GO EXEC sp_bindefault ‘DE_salary’, ‘employee. 工资 ’ GO 创建默认
