JDBC入门教程 – 终极指南
本教程主要介绍JDBC（Java数据库连接）—— 一个Oracle提供的API，它可以帮助程序员处理Java应用程序中不同数据库的访问问题：程序员可以通过它建立与数据库的连接；定义特定的客户端使之可以访问给定的数据库；提供一种能够读取、插入、更新和删除数据库中的数据项的机制；以及控制由不同SQL语句组成的事务。在本文中我们会介绍主要的JDBC组件，包括声明（Statement）、结果集（Result Set）、存储过程（Stored Procedure）。程序员们需要针对不同的数据库提供相应的驱动程序；在后面的章节我们会结合一些实例来详细解释。 JDBC是伴随Java的产生而产生的；它的第一个版本产生于1997年2月，也就是JDK1.1的发布日期；自那以后，JDBC已经成为Java的一个重要组成部分。JDBC相关的主要包有： http://docs.oracle.com/javase/8/docs/api/java/sql/package-summary.html 和http://docs.oracle.com/javase/8/docs/api/javax/sql/package-summary.html. 关于JDBC的最新版本和开发、维护信息可以访问JSR 221获得。本文中的所有例子的实现环境是Java 8 update 0_25和Eclipse SDK Luna 4.4. 你可以在本文的最后下载所有这些例子，而且还可以下载其他更多的例子！目录 1. 组件（Components） 2. 数据库连接（Connections） 3. 数据类型（Data types） 4. 驱动程序（Drivers） 5. 数据库（Databases） 6. 结果集（Result…
