使用SQLite3开发java应用程序

这里给出一个中文站点的URL:
http://www.sqlite.com.cn/Upfiles/source/sqlitejdbc-v033-nested.tgz
将下载到的包解压后得到jar包 sqlitejdbc-v033-nested.jar 放到%JAVA_HOME%\lib 下，
并且将其添加到classpath系统环境变量中,我的classpath系统环境变量现在为:
.;%JAVA_HOME%\lib\sqlitejdbc-v033-nested.jar
在你的代码中引用这个驱动:
    Class.forName("org.sqlite.JDBC");
    Connection conn = DriverManager.getConnection("jdbc:sqlite:filename");//filename为你的SQLite数据名称
    // ... use the database ...
    conn.close();
 
示例程序如下：


import java.sql.*;
import org.sqlite.JDBC;

public class TestSQLite
{
    public static void main(String[] args)
    {
        try
        {
         //连接SQLite的JDBC

         Class.forName("org.sqlite.JDBC");
       
         //建立一个数据库名zieckey.db的连接，如果不存在就在当前目录下创建之

         Connection conn = DriverManager.getConnection("jdbc:sqlite:zieckey.db");
       
         Statement stat = conn.createStatement();
       
         stat.executeUpdate( "create table tbl1(name varchar(20), salary int);" );//创建一个表，两列

       
         stat.executeUpdate( "insert into tbl1 values('ZhangSan',8000);" ); //插入数据

   stat.executeUpdate( "insert into tbl1 values('LiSi',7800);" );
   stat.executeUpdate( "insert into tbl1 values('WangWu',5800);" );
   stat.executeUpdate( "insert into tbl1 values('ZhaoLiu',9100);" );

         ResultSet rs = stat.executeQuery("select * from tbl1;"); //查询数据

         while (rs.next()) { //将查询到的数据打印出来

             System.out.print("name = " + rs.getString("name") + " "); //列属性一

             System.out.println("salary = " + rs.getString("salary")); //列属性二

         }
         rs.close();
         conn.close(); //结束数据库的连接

        }
        catch( Exception e )
        {
         e.printStackTrace ( );
        }
    }
}

编译运行： 


E:\Coding\java\test>javac TestSQLite.java
E:\Coding\java\test>java TestSQLite
name = ZhangSan       salary = 8000
name = LiSi       salary = 7800
name = WangWu       salary = 5800
name = ZhaoLiu       salary = 9100


总结：本文介绍了嵌入式数据库SQLite在Java中的应用，
通过创建表、插入数据、查询等操作介绍了在Java中对数据库的操纵。

SQLite3命令操作大全========================================================>>

.数据库、表的建立，记录的添加、查询、修改和删除

F:\>sqlite3 database.db
sqlite> create table admin(username text,age integer);
sqlite> insert into admin values('kuang',25);
sqlite> select * from admin;
sqlite> update admin set username='kk',age=24 where username='kuang' and age=25;
sqlite> delete from admin where username='kk';

注：每条sql语句后必须以";"号结尾！
