使用SQLite3开发java应用程序

前端之家收集整理的这篇文章主要介绍了使用SQLite3开发java应用程序前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。

使用SQLite3开发java应用程序

sqlite数据库的JDBC
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:
@H_711_403@ @H_98_404@

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!
