PHP 调用oracle存储过程

　　　　　　　　　$orderdate = strtotime($this->input->get('orderdate'));
                $today = strtotime(date('Y-m-d',time()));
　　　　　　　　　$num = ceil(($orderdate - $today)/86400); 

                $conn = oci_connect('username','password',"(DEscriptION=(ADDRESS=(PROTOCOL =TCP)(HOST=host)(PORT = 1521))(CONNECT_DATA =(SID=sid)))");
                $sql = 'BEGIN PROC_CREATEORDERDETAIL(:INPUTNUM); END;';
                $stmt = oci_parse($conn,$sql); //编译  　　　　　　　　　　
                oci_bind_by_name($stmt,':INPUTNUM',$num,32);  //参数绑定                      if(oci_execute($stmt)){
                    echo "<script>window.alert(\"已重新生成当日订单明细\"),location.href=\"http://bi.xiaoyou-game.com/order/lists\";</script>";

存储过程：

create or replace PROCEDURE  PROC_CREATEORDERDETAIL(INPUTNUM IN NUMBER)
AS
V_AMOUNT_REMAIN  NUMBER;
BEGIN

  DELETE FROM TBL_NEW_PLAN_HOUR T WHERE SUBSTR(T.PLAN_HOUR,0,10)=TO_CHAR(SYSDATE+INPUTNUM,'YYYY-MM-DD');
  INSERT INTO TBL_NEW_PLAN_HOUR(ORDERID,DIM_HOUR,HOUR_AMOUNT,PLAN_HOUR,FINISHED_AMOUNT,SCRIPTPACKAGE)
  SELECT OL.ORDERID,
         T.DIM_HOUR,
         ROUND(OL.ORDERAMOUNT*T.RADIO/100) AS HOUR_AMOUNT,
         TO_CHAR(TO_DATE(OL.ORDERDATE,'YYYY-MM-DD HH24:MI:SS')+T.DIM_HOUR/24,'YYYY-MM-DD HH24:MI:SS') AS PLAN_HOUR,
         0 AS FINISHED_AMOUNT,
         ol.SCRIPTPACKAGE
  FROM   TBL_NEW_RADIO T,ORDERLIST OL
  WHERE  OL.ORDERDATE=TO_CHAR(SYSDATE+INPUTNUM,'YYYY-MM-DD');
  COMMIT;

END;
