how to display parameter values instead of question marks in log file

How to display parameter values instead of question marks in log file as below..

SELECT 
  CASE 
   WHEN (a.CNT = 0 AND b.cnt = 0) THEN 'N'
   ELSE  CASE  WHEN a.CNT = b.CNT THEN 'Y'
         ELSE 'N' END 
   END      AS Final_Status
FROM
  (SELECT NVL(COUNT(*),1) CNT
  FROM FPC_INFO
  WHERE BILL_MONTH_DT = ?
  AND CUST_TYPE_NM    = UPPER(?)
  AND FINALIZED_USER IS NOT NULL
  ) a,
  (SELECT COUNT(*) CNT
  FROM FPC_INFO
  WHERE BILL_MONTH_DT = ?
  AND CUST_TYPE_NM    = UPPER(?)
  ) b

My expectation is like:

SELECT 
  CASE 
   WHEN (a.CNT = 0 AND b.cnt = 0) THEN 'N'
   ELSE  CASE  WHEN a.CNT = b.CNT THEN 'Y'
         ELSE 'N' END 
   END      AS Final_Status
FROM
  (SELECT NVL(COUNT(*),1) CNT
  FROM FPC_INFO
  WHERE BILL_MONTH_DT = '01-SEP-2015'
  AND CUST_TYPE_NM    = UPPER('UVERSE')
  AND FINALIZED_USER IS NOT NULL
  ) a,
  (SELECT COUNT(*) CNT
  FROM FPC_INFO
  WHERE BILL_MONTH_DT = '01-SEP-2015'
  AND CUST_TYPE_NM    = UPPER('UVERSE')
  ) b

Sorry for unformatted code.

I'm getting log with question marks like below in Log file..

SELECT CASE WHEN (a.CNT = 0 AND b.cnt = 0) THEN 'N' ELSE CASE WHEN a.CNT = b.CNT THEN 'Y' ELSE 'N' END END AS Final_Status FROM (SELECT NVL(COUNT(),1) CNT FROM FPC_INFO WHERE BILL_MONTH_DT = ? AND CUST_TYPE_NM = UPPER(?) AND FINALIZED_USER IS NOT NULL) a, (SELECT COUNT() CNT FROM FPC_INFO WHERE BILL_MONTH_DT = ? AND CUST_TYPE_NM = UPPER(?)) b

But i'm expecting it to print like below with appended values in log file:

SELECT CASE WHEN (a.CNT = 0 AND b.cnt = 0) THEN 'N' ELSE CASE WHEN a.CNT = b.CNT THEN 'Y' ELSE 'N' END END AS Final_Status FROM (SELECT NVL(COUNT(),1) CNT FROM FPC_INFO WHERE BILL_MONTH_DT = '01-SEP-2015' AND CUST_TYPE_NM = UPPER('UVERSE') AND FINALIZED_USER IS NOT NULL) a, (SELECT COUNT() CNT FROM FPC_INFO WHERE BILL_MONTH_DT = '01-SEP-2015' AND CUST_TYPE_NM = UPPER('UVERSE')) b
