sqlite - java 初学

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();
         }

     }

 }
