Java操作SQLite数据库

sqlite-jdbc 仓库地址：

https://bitbucket.org/xerial/sqlite-jdbc

sqlite-jdbc.jar

1、下载地址

https://bitbucket.org/xerial/sqlite-jdbc/downloads/

2、示例代码

package com.mouday;

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


public class App 
{ public static void main( String[] args ) throws ClassNotFoundException, SQLException { Class.forName("org.sqlite.JDBC"); Connection connection = DriverManager.getConnection("jdbc:sqlite:test.db"); System.out.println( "Hello World!" ); }
}

3、运行测试

javac com.mouday.App

# Mac or Linux
java  -classpath ".:sqlite-jdbc-3.7.2.jar" com.mouday.App

# Windows
java  -classpath ".;sqlite-jdbc-3.7.2.jar" com.mouday.App

SQLite的存储类

1. NULL
2. INTEGER 带符号的整数
3. REAL 浮点值
4. TEXT 文本字符串
5. BLOB

定义数据结构

package com.mouday;

public class Person { private int id; private String name; public Person(int id, String name) { this.id = id; this.name = name; } public int getId() { return id; } public void setId(int id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; }
}

CURD

package com.mouday;

import java.sql.*;
import java.util.ArrayList;
import java.util.List;

public class App { public static void main(String[] args) throws ClassNotFoundException { // 加载驱动 Class.forName("org.sqlite.JDBC"); Connection connection = null; try { // 获取连接 connection = DriverManager.getConnection("jdbc:sqlite:test.db"); Statement statement = connection.createStatement(); // 建表 statement.executeUpdate("drop table if exists person"); statement.executeUpdate("create table person (id integer , name text)"); // 插入数据 statement.executeUpdate("insert into person(id, name) values(1, '刘备')"); statement.executeUpdate("insert into person(id, name) values(2, '关羽')"); statement.executeUpdate("insert into person(id, name) values(3, '张飞')"); // 更新数据 statement.executeUpdate("update person set name='诸葛亮' where id = 2"); // 删除数据 statement.executeUpdate("delete from person where id = 3"); // 批处理 String  sql = "insert into person(id, name) values(?, ?)"; PreparedStatement preparedStatement = connection.prepareStatement(sql); List<Person> list = new ArrayList<>(); list.add(new Person(4, "Tom")); list.add(new Person(5, "曹操")); list.add(new Person(6, "刘备")); for(Person person: list){ preparedStatement.setInt(1, person.getId()); preparedStatement.setString(2, person.getName()); preparedStatement.addBatch(); } preparedStatement.executeBatch(); preparedStatement.close(); // 查询数据 ResultSet resultSet = statement.executeQuery("select * from person"); while (resultSet.next()){ System.out.println(resultSet.getInt("id")); System.out.println(resultSet.getString("name")); } statement.close(); } catch (SQLException e) { e.printStackTrace(); } finally { try{ if( connection != null){ connection.close(); } } catch (SQLException e) { e.printStackTrace(); } } }
}
