Java与JDBC驱动连接并查询数据库，Java 需要通过JDBC 对数据库进行查询，以完成对信息的收集、分类和展示的功能。在JDBC 中对数据库的查询有一般查询、参数查询和存储过程这样三类。本例在此实现这三种查询方法。程序运行后先对数据库执行一般查询，接着执行参数查询，最后执行存储过程。程序运行结果将根据用户的数据库中数据来确定-Java and JDBC driver to connect and query the database, Java needs to query the database via JDBC to complete the collection of information, classification and display functions. In JDBC there is general inquiries, queries and stored procedure parameters such categories to query the database. This example queries in this implementation of these three methods. After the first implementation of the program in general queries run against the database, and then execute the query parameters, and finally execute the stored procedure. The result of the program data in the database is determined according to the user s
