I have a Table called TaxAmount. It has 3 columns(ID, Year, Amount). refer the below image.
I want to divide each row into 12 months. I attached a sample image below.
I'm new in Oracle side. please help me to write a Oracle Query to display the above result.
I tried ROWNUM. But No luck.
Here's one option:
SQL> select id, year, column_value as month, amount
2 from taxamount cross join
3 table(cast(multiset(select level from dual
4 connect by level <= 12
5 ) as sys.odcinumberlist))
6 order by id, year, month;
ID YEAR MONTH AMOUNT

I have a table that is layed out as follows :
Code,Year, Wk1Val, Wk2Val, Wk3Val, Wk4Val etc to to Wk52Val.
Is there SQL to show the data as follows, without having to do 52 Case statements :
Code, Year, Week, Value
You can use UNPIVOT with REPLACE functions. Be sure to add all 52 week columns to the UNPIVOT IN portion of the query.
SELECT
u.Code,
u.Year,
REPLACE(REPLACE(u.Weeks, 'Wk', ''), 'Val', '') AS Weeks,
u.Value
FROM test
UNPIVOT
(
Value FOR Weeks IN (Wk1Val, Wk2Val, Wk3Val, Wk4Val, Wk52Val)
) AS u;

I am trying to use common table expression to split an yearly record into 12 monthly records. I have to do it for next 20 years records . That means 20 rows into 600 rows (20*12=600 records).
What is the best way to do it. Can anyone help with an efficient way to do it.
Using a single table as shown below. Year 0 means current year so it should split into remaining months and year=1 means next year onward it should split into 12 (months) records
id year value
1 0 3155174.87
1 1 30423037.3
1 2 35339631.25
expected result should look like this:
Id Year Month Value Calender year
1 0 5 150 2022
1 0 6 150 2022
1 0 7 150 2022
1 0 8 150 2022
1 0 9 150 2022
1 0 10 150 2022
1 0 11 150 2022
1 0 12 150 2022
1 0 1 150 2023
1 0 2 150 2023
1 0 3 150 2023
1 0 4 150 2023
1 1 5 100 2023
1 1 6 100 2023
1 1 7 100 2023
1 1 8 100 2023
1 1 9 100 2023
1 1 10 100 2023
1 1 11 100 2023
1 1 12 100 2023
1 1 1 100 2024
1 1 2 100 2024
1 1 3 100 2024
1 1 4 100 2024
You can simply join onto a list of months, and then use a bit of arithmetic to split the Value
SELECT
t.Id,
t.Year,
v.Month,
Value = t.Value / CASE WHEN t.Year = 0 THEN 13 - MONTH(GETDATE()) ELSE 12 END
FROM YourTable t
JOIN (VALUES
(1),(2),(3),(4),(5),(6),(7),(8),(9),(10),(11),(12)
) v(Month) ON t.year > 0 OR v.Month >= MONTH(GETDATE());

While transposing single columns is pretty straight forward I need to transpose a large amount of data with 3 sets of , 10+ related columns needed to be transposed.
create table test
(month int,year int,po1 int,po2 int,ro1 int,ro2 int,mo1 int,mo2 int, mo3 int);
insert into test
values
(5,2013,100,20,10,1,3,4,5),(4,2014,200,30,20,2,4,5,6),(6,2015,200,80,30,3,5,6,7) ;
select * FROM test;
gives

Maybe use a query like below which creates rows as per your design using CROSS APPLY
select month,year,po,ro,mo from
test cross apply
(values (po1,ro1,mo1), (po2,ro2,mo2),(0,0,mo3))v(po,ro,mo)
see demo here
Unpivot acts similar as union,Use union all in your case
SELECT month,
year,
po1 AS PO,
ro1 AS RO,
mo1 AS MO
FROM test
UNION ALL
SELECT month,
year,
po2,
ro2,
mo2
FROM test
UNION ALL
SELECT month,
year,
0,
0,
mo2
FROM test
I have a data frame as shown below. which is a sales data of two health care product starting from December 2016 to November 2018.
product price sale_date discount
A 50 2016-12-01 5
A 50 2017-01-03 4
B 200 2016-12-24 10
A 50 2017-01-18 3
B 200 2017-01-28 15
A 50 2017-01-18 6
B 200 2017-01-28 20
A 50 2017-04-18 6
B 200 2017-12-08 25
A 50 2017-11-18 6
B 200 2017-08-21 20
B 200 2017-12-28 30
A 50 2018-03-18 10
B 300 2018-06-08 45
B 300 2018-09-20 50
A 50 2018-11-18 8
B 300 2018-11-28 35
From the above I would like to prepare below data frame
Expected Output:
product year number_of_months total_price total_discount number_of_sales
A 2016 1 50 5 1
B 2016 1 200 10 1
A 2017 12 250 25 5
B 2017 12 1000 110 5
A 2018 11 100 18 2
B 2018 11 900 130 3
Note: Please note that the data starts from Dec 2016 to Nov 2018.
So number of months in 2016 is 1, in 2017 we have full data so 12 months and 2018 we have 11 months.
First aggregate sum by years and product and then create new column for counts by months by DataFrame.insert and Series.map:
df1 =(df.groupby(['product',df['sale_date'].dt.year], sort=False).sum().add_prefix('total_')
.reset_index())
df1.insert(2,'number_of_months', df1['sale_date'].map({2016:1, 2017:12, 2018:11}))
print (df1)
product sale_date number_of_months total_price total_discount
0 A 2016 1 50 5
1 A 2017 12 250 25
2 B 2016 1 200 10
3 B 2017 12 1000 110
4 A 2018 11 100 18
5 B 2018 11 900 130
If want dynamic dictionary by minumal and maximal datetimes use:
s = pd.date_range(df['sale_date'].min(), df['sale_date'].max(), freq='MS')
d = s.year.value_counts().to_dict()
print (d)
{2017: 12, 2018: 11, 2016: 1}
df1 = (df.groupby(['product',df['sale_date'].dt.year], sort=False).sum().add_prefix('total_')
.reset_index())
df1.insert(2,'number_of_months', df1['sale_date'].map(d))
print (df1)
product sale_date number_of_months total_price total_discount
0 A 2016 1 50 5
1 A 2017 12 250 25
2 B 2016 1 200 10
3 B 2017 12 1000 110
4 A 2018 11 100 18
5 B 2018 11 900 130
For ploting is used DataFrame.set_index with DataFrame.unstack:
df2 = (df1.set_index(['sale_date','product'])[['total_price','total_discount']]
.unstack(fill_value=0))
df2.columns = df2.columns.map('_'.join)
print (df2)
total_price_A total_price_B total_discount_A total_discount_B
sale_date
2016 50 200 5 10
2017 250 1000 25 110
2018 100 900 18 130
df2.plot()
EDIT:
df1 = (df.groupby(['product',df['sale_date'].dt.year], sort=False)
.agg( total_price=('price','sum'),
total_discount=('discount','sum'),
number_of_sales=('discount','size'))
.reset_index())
df1.insert(2,'number_of_months', df1['sale_date'].map({2016:1, 2017:12, 2018:11}))
print (df1)
product sale_date number_of_months total_price total_discount \

I have a table that looks like the following:
Accountno | MonthPeriod | YearPeriod | Value | StartYear | StartMonth | EndYear | Endmonth
---------- ------------- ------------ ------- ----------- ------------ --------- --------
210 4 2015 100 2015 1 2016 5
210 2 2016 200 2015 1 2016 5
300 4 2015 50 2015 1 2016 5
300 2 2016 100 2015 1 2016 5
I am looking for a way to fill in the missing months and years between the startmonth/startyear and endmonth/endyear, where the values for the newly populated entries will be of the previously populated values - populating the values backwards if that makes any sense? And for the entries towards the endyear/endmonth the accountno's last value (As the desired output table below)
Accountno | MonthPeriod | YearPeriod | Value | StartYear | StartMonth | EndYear | Endmonth
