Hi All,

Need help on populating prev day data in current day if missing

My Source table data is a below

Select * from 
(
select 'A' report_number, '12-NOV-2015' buss_date, 12323 num, 'D' dir, 09 bal from dual
UNION ALL
select 'A' report_number, '11-NOV-2015' buss_date, 12323 num, 'D' dir, 10 bal from dual
UNION ALL
select 'A' report_number, '11-NOV-2015' buss_date, 12323 num, 'E' dir, 100 bal from dual
UNION ALL
select 'A' report_number, '11-NOV-2015' buss_date, 12323 num, 'E' dir, 9 bal from dual
) neg

need output as below, i tried with outer join condition and LEAD and LAG for generic query, as the table is 12GB it is taking lot of time
Basically if i have recived 3 records yesterday , i need to make sure i have the same 3 record combination today with balance as 0 even 
if i have not received the record with same combination of NUM and DIR


Select * from 
(
select 'A' report_number, '12-NOV-2015' buss_date, 12323 num, 'D' dir, 19 bal from dual
UNION ALL
select 'A' report_number, '12-NOV-2015' buss_date, 12323 num, 'E' dir, 0 bal from dual
UNION ALL
select 'A' report_number, '11-NOV-2015' buss_date, 12323 num, 'D' dir, 10 bal from dual
UNION ALL
select 'A' report_number, '11-NOV-2015' buss_date, 12323 num, 'E' dir, 109 bal from dual
) neg

This is completely pointless for me, above when there are no dates in the rows.
How "dir" comes into play in the requirement?
How "report_number" does?
And "num"?
"3 records" define "3 records" or define "same 3 record combination".

There are too few rows in your "test case" to match all possible cases, complete it.
And post the result you want AS A CHART not a query, or do you want the result to be a query?
And ALIGN the columns in the result.

My Source table data is a below

drop table negative_balance_mov

Create table negative_balance_mov
as
Select * from 
(
select 'A' report_number, TO_DATE('12-NOV-2015','DD-MON-YYYY') buss_date, 12323 num, 'D' dir, 09 bal from dual
UNION ALL
select 'A' report_number, TO_DATE('11-NOV-2015','DD-MON-YYYY') buss_date, 12323 num, 'D' dir, 10 bal from dual
UNION ALL
select 'A' report_number, TO_DATE('11-NOV-2015','DD-MON-YYYY') buss_date, 12323 num, 'E' dir, 100 bal from dual
UNION ALL
select 'A' report_number, TO_DATE('11-NOV-2015','DD-MON-YYYY') buss_date, 12323 num, 'E' dir, 9 bal from dual
) neg

Report_number   Buss_date      Num      Dir   Balance
A               12-NOV-2015    12323    D    19
A               12-NOV-2015    12323    E    0          --- This record did not exists in my 12 Nov 2015 combination is Num and Dir, 
                                                        --i have to populate it with 0 as balance with current date as i have to 
                                                           calculate balance movement from previous day to current day, if record does 
                                                           not exists the current day with the Dir and Num values same as 11 nov 2015,  
                                                            the balance is not getting calculated i need to just populate a dummy  
                                                            record with 0
A               11-NOV-2015    12323    D    10
A               11-NOV-2015    12323    E    109        --- This is SUM(balance) grouped by report_number, buss_date,num and dir

Adding to above when i run a query as below

with neg_bal as
(select 
report_number, 
buss_date,
num,
dir,
sum(bal) bal
from negative_balance_mov
group by 
report_number, 
buss_date,
num,
dir)
select 
report_number, 
buss_date,
num,
dir,
bal,
(select bal from neg_bal
where buss_date = a.buss_date -1
and num = a.num
and dir = A.DIR
) prev_day_bal
 from neg_bal a

I get ouput only with 3 records . but i need the 4th record als0
report_number   buss_date       num     dir     bal     prev_day_bal
A	        11/11/2015	12323	E	109	
A	        11/11/2015	12323	D	10	
A	        11/12/2015	12323	D	9	10

Missing 4th record
A               11/12/2015	12323   E       0       109


Hope now i am clear with requirement

Why balance is 19 in first row?
Add a new 'D' at 11-MOV, how the result is changed?
Your requirements are not compete.
Your test case is not complete.
Given the complexity it requires at least 15 rows with more than one "report_number" and more than 2 dates.

Ah, you added some things when I was writing.

Not at all, you have now a new column in the result and not the same result in another column.
So it is clear as mud.

As I said many things are missing.

Sorry Michael

Ignore the previous thread, please see below hope i have tried to explain my requirement. The report number will be same for all records only the NUM and DIR column varies

drop table negative_balance_mov

Create table negative_balance_mov
as
Select * from 
(
select 'A' report_number, TO_DATE('12-NOV-2015','DD-MON-YYYY') buss_date, 12323 num, 'D' dir, 09 bal from dual
UNION ALL
select 'A' report_number, TO_DATE('11-NOV-2015','DD-MON-YYYY') buss_date, 12323 num, 'D' dir, 10 bal from dual
UNION ALL
select 'A' report_number, TO_DATE('11-NOV-2015','DD-MON-YYYY') buss_date, 12323 num, 'E' dir, 100 bal from dual
UNION ALL
select 'A' report_number, TO_DATE('11-NOV-2015','DD-MON-YYYY') buss_date, 12323 num, 'E' dir, 9 bal from dual
) neg


select * from negative_balance_mov


report_number   buss_date     num      dir  bal
A               11/12/2015    12323    D    9
A               11/11/2015    12323    D    10
A               11/11/2015    12323    E    100
A               11/11/2015    12323    E    9

I am running below query to get current balance - previous balance, but becuase the 11th Nov with Dir E has not come in 12th Nov the whole record is missing
i need that record with balance as zero and the prev_day balance as shown below in my expected output

with neg_bal as
(select 
report_number, 
buss_date,
num,
dir,
sum(bal) bal
from negative_balance_mov
group by 
report_number, 
buss_date,
num,
dir)
select 
report_number, 
buss_date,
num,
dir,
bal,
(select bal from neg_bal
where buss_date = a.buss_date -1
and num = a.num
and dir = A.DIR
) prev_day_bal
 from neg_bal a

I get ouput only with 3 records . but i need the 4th record als0
report_number   buss_date       num     dir     bal     prev_day_bal
A            11/11/2015    12323    E    109    
A            11/11/2015    12323    D    10    
A            11/12/2015    12323    D    9    10

Missing 4th record - I need to get this record also, how to change above query to get below record also
A               11/12/2015    12323   E       0       109
