sqlite

进来准备使用一种embedded database，即嵌入式数据库，方便随项目本地存储。目前学习打算是sqlite和H2。

1.连接数据库

添加依赖jdbc:

<dependency>
            <groupId>org.xerial</groupId>
            <artifactId>sqlite-jdbc</artifactId>
            <version>3.8.11.2</version>
</dependency>

　　

链接代码：

package com.test.database.sqlite;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;

/**
 * Created by miaorf on 2016/6/20.
 */
public class SQLiteJDBC {

    public static void main(String[] args) {
        
        Connection c = null;
        try {
            Class.forName("org.sqlite.JDBC");
            c= DriverManager.getConnection("jdbc:sqlite:test.db");

        } catch (ClassNotFoundException e) {
            e.printStackTrace();
        }catch (SQLException e) {
            e.printStackTrace();
        }

        System.out.println("Open databse successfully");
    }


}

执行结束发现，在项目根目录会生成一个叫做test.db的文件，这就是我们的数据库了。

2. 创建表

package com.test.database.sqlite;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
import java.sql.Statement;

/**
 * Created by miaorf on 2016/6/20.
 */
public class SQLiteJDBC {

    public static void main(String[] args) {

        Connection c = null;
        Statement stmt = null;
        try {
            Class.forName("org.sqlite.JDBC");
            c= DriverManager.getConnection("jdbc:sqlite:test.db");
            System.out.println("Opened database successfully");

            stmt = c.createStatement();
            String sql = "CREATE TABLE COMPANY " +
                    "(ID INT PRIMARY KEY     NOT NULL," +
                    " NAME           TEXT    NOT NULL, " +
                    " AGE            INT     NOT NULL, " +
                    " ADDRESS        CHAR(50), " +
                    " SALARY         REAL)";
            stmt.executeUpdate(sql);
            stmt.close();
            c.close();

            System.out.println("create table  successfully");

        } catch (ClassNotFoundException e) {
            e.printStackTrace();
        }catch (SQLException e) {
            e.printStackTrace();
        }


    }
