Question

如何在Oracle中使用Java存储过程

Answer 1

实例代码参考如下：
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;

/**
* Load JDBC Driver
* 最基本的方法通过JDBC连接数据库
* @author Jacob
*
*/
public class LoadByPrimary {

public static void main(String[] args) throws ClassNotFoundException
{
String driver = "oracle.jdbc.OracleDriver";
Connection cn = null;
/**
* Class.forName手动加载一个类到方法区，Driver类中包含自动注册驱动的静态代码块
* 会自动在DriverManager中注册驱动
*/
Class.forName(driver);
String url = "jdbc:oracle:thin:@localhost:1521:ORACLE"; //1521代表端口号，默认的
String user = "用户名";
String pwd = "密码";
try
{
/*
* Connection是接口，返回值是一个引用对象，是Oracle驱动提供实现类ojdbc7.jar
* 使用JDBC API接口，实际上是驱动实现类
*/
cn = DriverManager.getConnection(url,user,pwd);
Statement stmt = cn.createStatement();
String sql = "SELECT * FROM stu_emp WHERE deptno =10";
ResultSet rs = stmt.executeQuery(sql);
while(rs.next())
{
System.out.println(rs.getInt("empno")+" "+
rs.getString("ename")+" "+
rs.getString("job"));
}
rs.close();
stmt.close();
}
catch (SQLException e)
{
e.printStackTrace();
}
finally
{
try
{
if(cn!=null)
{
cn.close();
