存储过程是在大型数据库系统中，一组为了完成特定功能的SQL 语句集，存储在数据库中，经过第一次编译后再次调用不需要再次编译，用户通过指定存储过程的名字并给出参数（如果该存储过程带有参数）来执行它。今天，我们就开始学习java中调用oracle的存储过程。

一、 在数据库创建存储过程的脚本，如果使用的是本地的oracle数据库，则需要开启服务：OracleOraDb11g_home1TNSListener和OracleServiceORCL。

存储过程实现：输入用户的工号，输出用户的名字、薪水和工作。

create or replace procedure queryempinfo(eno in number,

pename out varchar2,

psal out number,

pjob out varchar2)

as

begin

--得到该员工的姓名 月薪和职位

select ename, sal, job into pename, psal, pjob from emp where empno = eno;

end;

二、 在项目中引入oracle的jdbc的jar包，Procedure的代码如下：

package com.tomhu.procedure;

import java.sql.CallableStatement;

import java.sql.Connection;

import java.sql.DriverManager;

import java.sql.ResultSet;

import java.sql.SQLException;

import oracle.jdbc.OracleTypes;

public class Procedure {

    private Connection conn;

    private CallableStatement stat;

    private ResultSet rs;

    String url = "jdbc:oracle:thin:@127.0.0.1:1521:orcl";

    String driverName = "oracle.jdbc.driver.OracleDriver";

    String username = "scott";

    String password = "******";

    String sql = "call queryempinfo(?,?,?,?)";

    // 调用存储过程

    public void callProcedure() {

        try {

            Class.forName(driverName);

            conn = DriverManager.getConnection(url, username, password);

            stat = conn.prepareCall(sql);

            // 一个输入参数和三个输出参数

            stat.setInt(1, 7566);

            stat.registerOutParameter(2, OracleTypes.VARCHAR);

            stat.registerOutParameter(3, OracleTypes.NUMBER);

            stat.registerOutParameter(4, OracleTypes.VARCHAR);

            stat.execute();

            String name = stat.getString(2);

            int sal = stat.getInt(3);

            String job = stat.getString(4);

            System.out.println("name: " + name + ", sal: " + sal + ", job: " + job);

        } catch (Exception e) {

            e.printStackTrace();

        } finally {

            close(conn, stat, rs);

        }

    }

    // 关闭连接

    public void close(Connection conn, CallableStatement stat, ResultSet rs) {

        if (rs != null) {

            try {

                rs.close();

            } catch (SQLException e) {

                e.printStackTrace();

            } finally {

                rs = null;

            }

        }

        if (stat != null) {

            try {

                stat.close();

            } catch (SQLException e) {

                e.printStackTrace();

            } finally {

                stat = null;

            }

        }

        if (conn != null) {

            try {

                conn.close();

            } catch (SQLException e) {

                e.printStackTrace();

            } finally {

                conn = null;

            }

        }

    }

    public static void main(String[] args) {

        new Procedure().callProcedure();

    }

}

三、 得到的输出结果：
