创建原始数据库——创建数据、创建表

书籍：数据库系统原理与设计(第3版)——万常选 廖国琼等编著任务驱动：由于找不到原始数据库,只有从零开始创建数据库、设计数据库关系图、输入数据，为后面深入研究数据库做好数据准备。数据库版本：SQL Server 2005操作步骤：1.创建数据库源码如下或是通过数据库管理工具创建数据库USE [master]GO/****** 对象: Database [ScoreDB] 脚本日期: 11/28/2018 21:44:34 ******/CREATE DATABASE [ScoreDB] ON PRIMARY( NAME = N’ScoreDB’, FILENAME = N’D:Program Files (x86)Microsoft SQL ServerMSSQL.1MSSQLDATAScoreDB.mdf’ , SIZE = 3072KB , MAXSIZE = UNLIMITED, FILEGROWTH = 1024KB )LOG ON( NAME = N’ScoreDB_log’, FILENAME = N’D:Program Files (x86)Microsoft SQL ServerMSSQL.1MSSQLDATAScoreDB_log.ldf’ , SIZE = 1024KB , MAXSIZE = 2048GB , FILEGROWTH = 10%)COLLATE Chinese_PRC_CI_ASGOEXEC dbo.sp_dbcmptlevel @dbname=N’ScoreDB’, @new_cmptlevel=90GOIF (1 = FULLTEXTSERVICEPROPERTY(‘IsFullTextInstalled’))beginEXEC [ScoreDB].[dbo].[sp_fulltext_database] @action = ‘disable’endGOALTER DATABASE [ScoreDB] SET ANSI_NULL_DEFAULT OFFGOALTER DATABASE [ScoreDB] SET ANSI_NULLS OFFGOALTER DATABASE [ScoreDB] SET ANSI_PADDING OFFGOALTER DATABASE [ScoreDB] SET ANSI_WARNINGS OFFGOALTER DATABASE [ScoreDB] SET ARITHABORT OFFGOALTER DATABASE [ScoreDB] SET AUTO_CLOSE OFFGOALTER DATABASE [ScoreDB] SET AUTO_CREATE_STATISTICS ONGOALTER DATABASE [ScoreDB] SET AUTO_SHRINK OFFGOALTER DATABASE [ScoreDB] SET AUTO_UPDATE_STATISTICS ONGOALTER DATABASE [ScoreDB] SET CURSOR_CLOSE_ON_COMMIT OFFGOALTER DATABASE [ScoreDB] SET CURSOR_DEFAULT GLOBALGOALTER DATABASE [ScoreDB] SET CONCAT_NULL_YIELDS_NULL OFFGOALTER DATABASE [ScoreDB] SET NUMERIC_ROUNDABORT OFFGOALTER DATABASE [ScoreDB] SET QUOTED_IDENTIFIER OFFGOALTER DATABASE [ScoreDB] SET RECURSIVE_TRIGGERS OFFGOALTER DATABASE [ScoreDB] SET ENABLE_BROKERGOALTER DATABASE [ScoreDB] SET AUTO_UPDATE_STATISTICS_ASYNC OFFGOALTER DATABASE [ScoreDB] SET DATE_CORRELATION_OPTIMIZATION OFFGOALTER DATABASE [ScoreDB] SET TRUSTWORTHY OFFGOALTER DATABASE [ScoreDB] SET ALLOW_SNAPSHOT_ISOLATION OFFGOALTER DATABASE [ScoreDB] SET PARAMETERIZATION SIMPLEGOALTER DATABASE [ScoreDB] SET READ_WRITEGOALTER DATABASE [ScoreDB] SET RECOVERY FULLGOALTER DATABASE [ScoreDB] SET MULTI_USERGOALTER DATABASE [ScoreDB] SET PAGE_VERIFY CHECKSUMGOALTER DATABASE [ScoreDB] SET DB_CHAINING OFF2.创建表源码如下或是通过数据库管理工具创建表
