众所周知,JDBC(Java数据库连接)是Java 2企业版的重要组成部分。它是基于SQL层的API。通过把SQL语句嵌入JDBC接口的方法中,用户可以通过Java程序执行几乎所有的数据库操作。JDBC只提供了接口,具体的类的实现要求数据库的设计者完成。通过生成这些接口的实例,即使对于不同的数据库,Java程序也可以正确地执行SQL调用。所以对于程序员来说,不必把注意力放在如何向数据库发送SQL指令,因为程序员需要了解和用到的只是JDBC的接口,只有在极少数情况下会用到面向特定数据库的类,例如程序员希望使用ORACLE的扩展API。-known, JDBC (Java Database Connectivity) is a Java 2 Enterprise Edition of the important components. It is based on SQL API layer. Through JDBC embedded SQL interface method, Java users can implement procedures almost all of the data base. JDBC interface provides only a specific category of demands on the database designer to complete. Interface generated by these examples, even for the different databases, Java programs can also correct implementation of SQL calls. So programmers, we do not have to focus on how to send SQL database directive because programmers need to understand and use the only JDBC interface Only in very rare cases, will use the database for specific categories, For example, programmers hope to expan
