sqlserver命令創建數據庫和表 demo

由於sqlserver用起來很不爽 可以嘗試用vscode+sqlserver插件玩玩

友情提示 在vscode中新建一個.sql 並配置好與sqlserver的連接 利用sql會有提示創建表 數據庫等 爽歪歪 右鍵選擇最下面的執行query 

-- Create a new database called 'DatabaseName'
-- Connect to the 'master' database to run this snippet
-- USE master
-- GO
-- Create the new database if it does not exist already
-- 只是用來學習用的 具體細節自己加
CREATE DATABASE myfirestdata1010
on PRIMARY
(
    name = 'myfirestdata1010',
    FILENAME = 'E:\SQL Data\myfirestdata1010.mdf'
)
log ON
(
    name = 'myfirestdata1010_log',
    FILENAME = 'E:\SQL Data\myfirestdata1010_log.ldf'
)
GO

-- Create a new table called 'TableName' in schema 'SchemaName'
-- Drop the table if it already exists
-- IF OBJECT_ID('myfirestdata1010.students', 'U') IS NOT NULL
-- DROP TABLE myfirestdata1010.students
-- GO

USE myfirestdata1010;

-- DROP TABLE students;
-- Create the table in the specified schema
CREATE TABLE students
(
    stu_id INT PRIMARY key,
    stu_name VARCHAR(50) NOT NULL,
    stu_age INT NOT NULL CHECK(stu_age BETWEEN 16 and 22), 
    stu_sex CHAR(2) NOT NULL DEFAULT('男') CHECK (stu_sex='男' or stu_sex='女'),
    stu_address VARCHAR(50) NOT NULL,
    stu_email VARCHAR(50) NOT NULL CHECK (stu_email like '_%@_%.__%') UNIQUE
);
GO

-- DROP TABLE scoreInfo;

CREATE TABLE scoreInfo(
    score_id int PRIMARY KEY IDENTITY(1000,1),
    stu_id int FOREIGN KEY REFERENCES students(stu_id),
    score int NOT NULL
)
GO
