Java調用oracle存儲過程通過游標返回臨時表數據

 

 

  項目開發過程中，不可避免的會用到存儲過程返回結果集。特別是選擇Oracle做為數據庫時，就更麻煩了，因為Oracle存儲過程和SQLServer的有點不太一樣，直接返回不了結果集，那么怎么才能在使用Oracle的情況下返回結果集，程序代碼中怎么獲取到那，請看下面幾篇：

       1.存儲過程返回結果集

       2.Java中執行存儲過程以及多結果集處理

       3.返回臨時表中數據

 

 

 

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();
			//最關鍵一步
			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();
		}
	}

}
