数据库基础入门（三）——通过JDBC对数据库进行增删改查操作

何谓JDBC？

JDK提供了一组API，让我们可以在java程序中连结到网络上的数据库，并执行SQL语句返回执行结果，这组API的应用我们通常称作JDBC技术；相关的API都在包java.sql.\*下面。

Connection对象，则是由java.sql.DriverManager类的静态方法getConnection(…)得到，一但应用程序中得取一个Connection对象，即应用程序与数据库创建立了连结。随后，我们就可以通过操作Connection对象，创建Statement对象以执行sql语句，或从执行结果返回的ResultSet中取得查询结果。

以下是具体代码实现：

1)连接到数据库：

需要注意的是以下的几个参数，URL：本地用户localhost端口号默认为3306后面是数据库的名字。Username默认为root，密码就是你设置的数据库密码。Driver：MySQL的驱动名应写成(驱动jar包要从www.mysql.org上下载):com.mysql.jdbc.Driver

如果是没有加载驱动将会出现找不到驱动的错误：

2）使用预编译sql

数据库处理SQL语句时，需要一个预编译过程，数据库可以把一些格式固定的SQL编译后，存入在其内存池中，再次执行时即直接使用，不再执行预编译过程，这样可以有效提高数据库操作效率；我们可以通过预编译对象实现，如下代码示例：

每一个问号代表了一个表中的数值。其中的：pstmt.setString(1, username);1代表的是第几个占位符，既不能多也不能重复使用。

连结对象创建成功后，即可通过连结对象创建statement对象，以执行SQL语句。我们可将要执行的SQL语句分为两类，一类为需要返回结果表的select语句；一类为执行insert、update、delete操作的语句，因用程序只需要这类语句返回操作所生效的行数即可；对于这两种SQL操作，Statement在执行时可采用不同的方法，如是select语句，则使用executeQuery(sql)方法返回一个ResultSet对象，其中包含查询到的数据；如是另外三种，则使用executeUpdate(sql)方法，返回一个int型值，代表语句所影响的行数，如下代码示例：

一下是针对具体项目的完整代码：
