Objective:
To get the first next row of PAYMENT_DATE and its corresponding PAYMENT_AMT once null PAYMENT_DATE is encountered.
For example, for BILL_DATE 22-APR-2013 12:00:00 AM, there is no PAYMENT_DATE, thus the next payment available is 19-JUN-2013 with PAYMENT_AMT of 400 .


I've tried using LEAD that seems to solved the objective but I failed to make it show the correct BILL_DATE
select
bill_Date,
account_num,
case when payment_date is null then lead(PAYMENT_DATE,1) OVER (ORDER BY PAYMENT_DATE) else payment_date end PAYMENT_DATE,
case when payment_date is null then lead(PAYMENT_amt,1) OVER (ORDER BY PAYMENT_DATE) else payment_amt end PAYMENT_AMT 
from V_TMP_RPT_UNIFI_V2


Thank you.

For example:

insert into v_tmp_rpt_unifi_v2 (to_date('22-Jan-13','DD-Mon-YY'), '1009233022',to_date('11-Feb-13','DD-Mon-YY'), -340);


Should be:

insert into v_tmp_rpt_unifi_v2 (BILL_DATE, ACCOUNT_NUM, PAYMENT_DATE, PAYMENT_AMT) VALUES (to_date('22-Jan-13','DD-Mon-YY'), '1009233022',to_date('11-Feb-13','DD-Mon-YY'), -340);

Thanks.

But I'm still lost how to use that function in this case.

Can you please help.

Thank you.

Did you read the documentation, did you make any attempt to use the function with your data to see what it would do?
I assume that you have made some attempts prior to posting back? If so, post what you tried, we'll try to steer you from there Smile

I've tried it but there's nothing difference that I could see.

Finally, I go along with the conventional way which requires separate package to be executed:
select a.*, b.payment_amt from
(SELECT bill_date, account_num, payment_date
  FROM (select
        bill_date, account_num,
        PKG_RPT_UNIFI_v1.bill_payment_min(account_num,bill_date) payment_date,
        min(bill_date) OVER (partition by PKG_RPT_UNIFI_v1.bill_payment_min(account_num,bill_date)) maxcol
        from V_TMP_RPT_UNIFI_V2)
 WHERE bill_date=maxcol) a, v_tmp_rpt_unifi_v2 b
where a.account_num=b.account_num(+) and a.payment_date=b.payment_date(+)
order by 1,2,3;


Package
FUNCTION bill_payment_min (v_account_num in varchar2, v_bill_Date in date)
---------------------------------------------------------------------------------------
RETURN date
DETERMINISTIC
PARALLEL_ENABLE
IS v_count date;

BEGIN
       select min(payment_date) into v_Count
       FROM v_tmp_rpt_unifi_v2
       WHERE
       account_num = v_account_num and payment_Date >= v_bill_Date and payment_amt is not null;

RETURN (v_Count);

END;


Really hope that I could get it work through one single script.

Thank you.

Could someone proved me that the FIRST analytic function would work for this?

You say that you have tried it, but the code that you posted doesn't use it. Why not? I asked you to post your code where you tried to use the FIRST function, you posted code that does NOT use the first function (unless I'm missing something). I don't really understand why you would post the code that you did, it seems irrelevant to the documentation that I linked you to.

As I've mentioned to you, there is no difference when I'm using the FIRST. The code I used:
select
bill_date,
account_num,
min(payment_date) KEEP (DENSE_RANK FIRST ORDER BY bill_date) payment_date
from V_TMP_RPT_UNIFI_V2
group by account_num,
bill_date

The result is exactly the same as the input.

I already read the documentation but I could not digest it, that's why I'm asking for help here.

What's the point of me asking if no one is helping but only to ask me to read the documentation. Of course there's a lot of documentation out there.

Then you asked me why did I post those codes? It's simply because I am working on the solution by hook or by crook.

Thanks anyway.

I'm confused. You appear to be implying that you have written code using the FIRST syntax, yet you post code that is clearly not using the FIRST syntax and you also say:
Quote:
I already read the documentation but I could not digest it

Which would imply that you didn't understand the documentation and that therefore you were not able to use the FIRST syntax. Could you clarify which is the correct scenario?
In addition, cam you tell me what is wrong with using:
select *
from v_tmp_rpt_unifi_v2
where payment is not null


As it appears to return the results that you want from the data that you have supplied.

I did use FIRST as in the document example:
SELECT department_id,
MIN(salary) KEEP (DENSE_RANK [b]FIRST[/b] ORDER BY commission_pct) "Worst",
MAX(salary) KEEP (DENSE_RANK LAST ORDER BY commission_pct) "Best"
   FROM employees
   GROUP BY department_id;

My case
select
bill_date,
account_num,
min(payment_date) KEEP (DENSE_RANK [b]FIRST[/b] ORDER BY bill_date) payment_date
from V_TMP_RPT_UNIFI_V2
group by account_num,
bill_date

Maybe you just straight to the point of the question Get Min Value Where It Is Not Null
But actually if you read again my 1st post.
BILL_DATE	ACCOUNT_NUM	PAYMENT_DATE	PAYMENT_AMT

is not what I've been looking for.

Instead I want the output to come out like this

Thanks for your concern anyway.

Well, I guess I could never achieve it with extra work perhaps. That's why still nobody answered my question correctly.

You're definitely confused, query in the post above the one I quote pretty much exactly matches the example in the documentation page you've linked to. Did you actually mean first_value?

Here's one way:

  5                                   account_num,
  6                                   LAG(payment_date,1, payment_date)
  7                                       OVER (PARTITION BY account_num ORDER BY bill_date) last_pay

I split the data into two sets. One is the list of payment dates and payment amounts ordered by bill_date.
The other is the set of bill_dates that should be in the output.
I assigned a row_number to each set and used that to stitch them back together.
If you want to see what it's doing just run the two with clauses individually.

Finally...

Thanks a lot cookiemonster.

But I'm sorry to inform that with these set of data, your given solution as above seems invalid.

insert into v_tmp_rpt_unifi_v2 values (to_date('01-DEC-2013','DD-Mon-YY'), '1000085249',null, null);

would output

which should be
BILL_DATE                ACCOUNT_NUM    PAYMENT_DATE             PAYMENT_AMT
01-JAN-2013 12:00:00 AM  1000085249     04-FEB-2013 04:00:10 PM  -600

instead.

Any help?

Thank you.

The third parameter to lag is a default value to be used where there is no record in the window that can be checked. So it applies to the first record of a given partition. I used payment_date, which worked with the orginal data set but not this one. Change it to a value that can never be null - sysdate for example - and it'll work. The way the query is contructed it doesn't matter what exact value lag returns, just that it's not null.

Thanks again cookie.

But again Im really sorry, there's another rule, if the payment_date is less than the bill_date, it should be ignore and proceed with the next available payment date.

For example, this set of data

For the pay_dates portion, I think it could be modified as simply as
pay_dates AS (SELECT payment_date,
payment_amt,
account_num,
row_number() OVER (PARTITION BY account_num ORDER BY bill_date) payment_order
FROM V_TMP_RPT_UNIFI_V1 v
WHERE payment_date IS NOT NULL and payment_date >= bill_date
and account_num='1000071082'
)


But I have no idea on how I am going to order the bill_dates portion.

Your solution is actually significantly faster, so really appreciate if you could help.

Thank you.

You're right on the payment_Dates bit. To fix the other side you need to suppress payment_Date when it's invalid so that lag doesn't pick it up.
Do that by adding another level of nesting and a case statement to only return payment_date if it's valid:

SQL> WITH bill_dates AS (SELECT bill_date,
  2                                 account_num,
  3                                 row_number() OVER (PARTITION BY account_num ORDER BY bill_date) bill_order
  4                          FROM (SELECT bill_date,
  5                                       account_num,
  6                                       LAG(payment_date,1, SYSDATE)
  7                                           OVER (PARTITION BY account_num ORDER BY bill_date) last_pay

 10                                       CASE WHEN payment_date >= bill_date THEN payment_date END AS payment_date

I'm sorry but there are still few more cases that need to be cater.

For example, with this set of data
BILL_DATE                ACCOUNT_NUM    PAYMENT_DATE             PAYMENT_AMT
16-JAN-2013 12:00:00 AM  1006977209     23-JAN-2013 03:35:27 PM  -150

For each month, need only to pick up the min bill_Date. So, that the output would be:
BILL_DATE                ACCOUNT_NUM    PAYMENT_DATE             PAYMENT_AMT

It could be done with
min(bill_date) OVER (PARTITION BY to_char(bill_date, 'MON-YYYY')) AS min_bill
but where do I put it?

Since
SELECT bill_date, 
       account_num, 
       Row_number() 
         over ( 
           PARTITION BY account_num 
           ORDER BY bill_date) bill_order 
FROM   (SELECT bill_date, 
               account_num, 
               Lag(payment_date, 1, SYSDATE) 
                 over ( 
                   PARTITION BY account_num 
                   ORDER BY bill_date)                          last_pay, 
               Min(bill_date) 
                 over ( 
                   PARTITION BY To_char(bill_date, 'MON-YYYY')) AS min_bill 
        FROM   (SELECT bill_date, 
                       account_num, 
                       CASE 
                         WHEN payment_date >= bill_date THEN payment_date 
                       END AS payment_date 
                FROM   v_tmp_rpt_unifi_v2)) 
WHERE  last_pay IS NOT NULL 
       AND bill_date = min_bill 

would always eliminate the last bill_date Sad

OK.

I got it..
WITH bill_dates AS
   (SELECT bill_date,
    account_num,
    row_number() OVER (PARTITION BY account_num ORDER BY bill_date) bill_order
      FROM (SELECT bill_date,
            account_num,
            LAG(payment_date,1, SYSDATE)
            OVER (PARTITION BY account_num ORDER BY bill_date) last_pay
              FROM (SELECT bill_date,
                    account_num,
                    CASE WHEN payment_date >= bill_date THEN payment_date END AS payment_date,
                    min(bill_date) OVER (PARTITION BY account_num, to_char(bill_date, 'MON-YYYY')) AS min_bill
                    FROM V_TMP_RPT_UNIFI_V2
--                     where account_num='1009520352'
                   ) where bill_date = min_bill
             )
      WHERE last_pay IS NOT NULL
      )


Thanks a lot cookiemonster.

It should be this
BILL_DATE                ACCOUNT_NUM    PAYMENT_DATE             PAYMENT_AMT

I suspect the problem is that the data isn't what you think it is:

SQL> SELECT to_char(bill_date, 'dd-mon-yyyy hh:mi:ss am'),
  2  to_char(payment_date, 'dd-mon-yyyy hh:mi:ss am')
  3  FROM V_TMP_RPT_UNIFI_V2 ORDER BY bill_date;
 
TO_CHAR(BILL_DATE,'DD-MON-YYYY TO_CHAR(PAYMENT_DATE,'DD-MON-Y

All those bill_dates are 12PM, which is midday, not midnight.
Which means this:

I believe you wanted that date included, but by your rules it won't be.

Fix your inserts to use 24 hour times and then we'll see where we are.

I just moved the last_pay calculation down a level. It needs to be calculated over all the rows, not just the ones outputted from the bill_date = min_bill check.

right, so that's a direct knock-on from the previous change.
I'm afraid I'm getting confused myself at this point. We appear to have overlapping rules and I'm losing track of which takes precedence.
It would help a lot of you restated the rules as a simple list. The solution should be more obvious then.

Thanks for your concern.

OK, the rules:
1. Bill date for each month should only appear once, take the minimum.
2. The payment date should be greater than or equal to the bill date (only need to compare date parts).
3. The payment date is taken in such a way that it is the nearest next payment made as compared to the bill date.
4. The payment date should not be repeated and unique for each bill date.
5. Sample input/output

Input:
BILL_DATE                ACCOUNT_NUM    PAYMENT_DATE             PAYMENT_AMT
