Java调用oracle存储过程通过游标返回临时表数据

项目开发过程中，不可避免的会用到存储过程返回结果集。特别是选择Oracle做为数据库时，就更麻烦了，因为Oracle存储过程和SQLServer的有点不太一样，直接返回不了结果集，那么怎么才能在使用Oracle的情况下返回结果集，程序代码中怎么获取到那，请看下面几篇：

1.存储过程返回结果集

2.Java中执行存储过程以及多结果集处理

3.返回临时表中数据

 package com.zjhcsoft.test.utl;

 import java.sql.CallableStatement;
 import java.sql.Connection;
 import java.sql.DriverManager;
 import java.sql.ResultSet;

 import oracle.jdbc.OracleCallableStatement;
 import oracle.jdbc.driver.OracleTypes;

 public class TestOracleProc3 {

 	/**
 	 * @param args
 	 */
 	public static void main(String[] args) {
 		try {
 			Class.forName("oracle.jdbc.driver.OracleDriver");
 		} catch (Exception e) {
 			e.printStackTrace();
 		}

 		Connection conn = null;
 		String DBurl = "jdbc:oracle:thin:@134.98.8.168:1521:ora817";
 		try {
 			conn = DriverManager.getConnection(DBurl, "sfz2", "sfz2_123");
 			System.out.println("Getting Connection...");
 			conn.close();
 		} catch (Exception e) {
 			e.printStackTrace();
 		}

 		try {
 			conn = DriverManager.getConnection(DBurl, "sfz2", "sfz2_123");
 			long start = System.currentTimeMillis();
 			//最关键一步
 			conn.setAutoCommit(false);
 			OracleCallableStatement cstmt = (OracleCallableStatement)conn.prepareCall("{call sfz_obj.proc_sfz_proc_test(?,?)}");
 			cstmt.setString(1, "");
 			cstmt.registerOutParameter(2,OracleTypes.CURSOR);
 			cstmt.execute();
 			long end = System.currentTimeMillis();
 			System.out.println("this procedure consumes "+((end-start)/1000)+" excute time.");
 			start = System.currentTimeMillis();
 			int i=0;
 			ResultSet rs = (ResultSet)cstmt.getObject(2);
 			   while (rs.next()) {
 				   System.out.println("column"+(i+1)+":"+rs.getString(1)+",  "+rs.getString(2)+",  "+rs.getString(3));
 				   i++;
 			   }
 			   System.out.println("this procedure has "+(i-1)+" data.");
 			end = System.currentTimeMillis();
 			System.out.println("show this procedure data consumes "+((end-start)/1000)+" excute time.");
 			conn.commit();
 			cstmt.close();
 			conn.close();
 		} catch (Exception e) {
 			e.printStackTrace();
 		}
 	}

 }
