java 调用oracle存储过程

1.java代码
public static void callProducre() throws Exception {
		Connection conn = getConn();
		String sql = "{call exportExcle(?,?,?,?)}";
		CallableStatement statement = conn.prepareCall(sql);
		// 设置输入参数
		statement.setLong(1, 1);
		statement.setLong(2, 1000);
		// 设置输出参数
		statement.registerOutParameter(3, oracle.jdbc.OracleTypes.CURSOR);
		statement.registerOutParameter(4, oracle.jdbc.OracleTypes.NUMBER);
		
		statement.execute();
		
		// 处理返回结果集
		ResultSet rs = (ResultSet)statement.getObject(3);
		int i=1;
		while (rs.next()) {
			System.out.println(rs.getString(1)+":"+rs.getString(2));
			i++;
		}
		rs.close();
		// 输出第4个值
		BigDecimal outParam2 = (BigDecimal)statement.getObject(4);
		System.out.println("输出第4个值:"+outParam2.toString());
		
		statement.close();
		conn.close();
		
	}

 2.存储过程

 

create or replace procedure exportExcle(startNum in number,endNum in number,out_cursor out sys_refcursor,totalNum out number)
as 
begin
  open out_cursor for 
SELECT * 
 FROM (SELECT tt.*, ROWNUM AS rowno 
 FROM (
select distinct info.tradeno from sc_ipay_pay pay,sc_ipay_prepayment_info info where pay.bill_id=info.billid and pay.amount=29.9
and pay.pay_status=1 and info.user_goods_name like '%药安心%' and to_char(pay.create_time,'yyyy-MM-dd')>='2019-07-07'
order by info.tradeno desc 
) tt
 WHERE ROWNUM < endNum) al
 WHERE al.rowno >= startNum;
 
 totalNum:= startNum+endNum;
end exportExcle;
