I have one table like below in my SQL server.
Trans_id br_code bill_no amount
1 22 111 10
2 22 111 20
3 22 111 30
4 22 111 40
5 22 111 10
6 23 112 20
7 23 112 20
8 23 112 20
9 23 112 30
and I want desired output like below table
s.no br_code bill_no amount
1 22 111 110
2 23 112 90
try this:
select br_code, bill_no, sum(amount)
from TABLE
group by br_code, bill_no

I have a dataset, in which it has a lot of entries for a single location. I am trying to find a way to sum up all of those entries without affecting any of the other columns. So, just in case I'm not explaining it well enough, I want to use a dataset like this:
Locations Cyclists maleRunners femaleRunners maleCyclists femaleCyclists
Bedford 10 12 14 17 27
Bedford 11 40 34 9 1
Bedford 7 1 2 3 3
Leeds 1 1 2 0 0
Leeds 20 13 6 1 1
Bath 101 20 33 41 3
Bath 11 2 3 1 0
And turn it into something like this:
Locations Cyclists maleRunners femaleRunners maleCyclists femaleCyclists
Bedford 28 53 50 29 31
Leeds 21 33 39 1 1
Bath 111 22 36 42 3
Now, I have read up that a groupby should work in a way, but from my understanding a group by will change it into 2 columns and I don't particularly want to make hundreds of 2 columns and then merge it all. Surely there's a much simpler way to do this?
IIUC, groupby+sum will work for you:
df.groupby('Locations',as_index=False,sort=False).sum()
Output:
Locations Cyclists maleRunners femaleRunners maleCyclists femaleCyclists
0 Bedford 28 53 50 29 31
1 Leeds 21 14 8 1 1
2 Bath 112 22 36 42 3
Pivot table should work for you.
new_df = pd.pivot_table(df, values=['Cyclists', 'maleRunners', 'femalRunners',
'maleCyclists','femaleCyclists'],index='Locations', aggfunc=np.sum)
I have a view as follows:
id paperid papercode papername marks1 marks2 total
1 1 001 paper-1 10 35 45
2 2 001 paper-2 12 40 52
3 3 002 paper-3 9 30 39
Now, I want data as below:
id paperid papercode papername marks1 marks2 total
1 1 001 001 22 75 97
3 3 002 paper-3 9 30 39
You can try below -
select min(id),min(paperid),papercode,min(papername),sum(marks1),sum(marks2),sum(marks3)
from tablename
group by papercode
I will explain my problem briefly
have duplicate rino like below (actually this rino is the serial number in front end)
chqid rino branchid
----- ---- --------
876 6 2
14 6 2
18 10 2
828 10 2
829 11 2
19 11 2
830 12 2
20 12 2
78 40 2
1092 40 2
1094 41 2
79 41 2
413 43 2
1103 43 2
82 44 2
1104 44 2
1105 45 2
83 45 2
91 46 2
1106 46 2
here in my case I don't want to delete these duplicate rino instead of that I planned to update the rino having max date(column not specified in the above sample actually a date column is there) to the next rino number
what exactly I meant is :
if I sort out the above result according to the max(date) I will get
chqid rino branchid
----- ---- --------
876 6 2
828 10 2
19 11 2
830 12 2
1092 40 2
79 41 2
413 43 2
82 44 2
83 45 2
1106 46 2
(NOTE : total number of duplicate rows are 10 in branchid=2)
the last entered rino in the table for branchid=2 is 245
So I just want to update the 10 rows(Of column rino) with numbers starting from 246 to 255( just added 245+10 like this select lastno+ generate_series(1,10) nos from tab where cola=4 and branchid = 2 and vrid=20;)
Expected Output:
chqid rino branchid
----- ---- --------
876 246 2
828 247 2
19 248 2
830 249 2
1092 250 2
79 251 2
413 252 2
82 253 2
83 254 2
1106 255 2
using postgresql
Finally I found a solution, am using dynamic-sql to solve my issue
do
$$
declare
arow record;
begin
for arow in
select chqid,rino,branchid from (
select chqid,rino::int ,vrid,branchid ,row_number()over (partition by rino::int ) rn
from tab
where vrid =20
and branchid = 2)t
where rn >1
loop
execute format('
update tab
set rino=(select max(rino::int)+1 from gtab19 where acyrid=4 and branchid = 2 and vrid=20)
where chqid=%s
',arow.chqid);
end loop;
end;

I am using SQL Server 2008 R2. I do have records as below in a table :
Id Sys Dia Type UniqueId
1 156 20 first 12345
2 157 20 first 12345
3 150 15 last 12345
4 160 17 Average 12345
5 150 15 additional 12345
6 157 35 last 891011
7 156 25 Average 891011
8 163 35 last 789521
9 145 25 Average 789521
10 156 20 first 963215
11 150 15 last 963215
12 160 17 Average 963215
13 156 20 first 456878
14 157 20 first 456878
15 150 15 last 456878
16 160 17 Average 456878
17 150 15 last 246977
18 160 17 Average 246977
19 150 15 additional 246977
Regarding this data, these records are kind of groups that have common UniqueId. The records can be of type "first, last, average and additional". Now, from these records I want to select "average" type of records only if they have "first" or "additional" kind of reading in group. Else I want to exclude them from selection..
The expected result is :
Id Sys Dia Type UniqueId
1 156 20 first 12345
2 157 20 first 12345
3 150 15 last 12345
4 160 17 Average 12345
5 150 15 additional 12345
6 157 35 last 891011
7 163 35 last 789521
8 156 20 first 963215
9 150 15 last 963215
10 160 17 Average 963215
11 156 20 first 456878
12 157 20 first 456878
13 150 15 last 456878
14 160 17 Average 456878
15 150 15 last 246977
16 160 17 Average 246977
17 150 15 additional 246977
In short, I don't want to select the record that have type="Average" and have only "last" type of record with same UniqueId. Any solution?
Using EXISTS operator along correlated sub-query:
SELECT * FROM dbo.Table1 t1
WHERE [Type] != 'Average'
OR EXISTS (SELECT * FROM Table1 t2
WHERE t1.UniqueId = t2.UniqueId
AND t1.[Type] = 'Average'
AND t2.[Type] IN ('first','additional'))
SQLFiddle DEMO
Try something like this:
SELECT * FROM MyTable WHERE [Type] <> 'Average'
UNION ALL
SELECT * FROM MyTable T WHERE [Type] = 'Average'
AND EXISTS (SELECT * FROM MyTable
WHERE [Type] IN ('first', 'additional')
AND UniqueId = T.UniqueId)
The first SELECT statement gets all records except the ones with Type = 'Average'. The second SELECT statement gets only the Type = 'Average' records that have at least one record with the same UniqueId, that is of type 'first' or 'additional'.
I am using the following statement;
SELECT RESV_ID, BOOKING_CUS_ID, ACC_ID,
(SELECT F.FLI_PRICE FROM FLIGHT F WHERE F.FLI_ID = R.IN_FLIGHT_ID) AS DEPART_FLIGHT_PRICE,
(SELECT F1.FLI_PRICE FROM FLIGHT F1 WHERE F1.FLI_ID = R.OUT_FLIGHT_ID) AS RETURN_FLIGHT_PRICE,
(SELECT AC.ACC_PRICEPN FROM ACCOMMODATION AC WHERE AC.ACC_ID = R.ACC_ID) AS ACCOMMODATION_PRICE
FROM HOLIDAY_RESERVATION R;
to yield the following results;
RESV_ID BOOKING_CUS_ID ACC_ID DEPART_FLIGHT_PRICE RETURN_FLIGHT_PRICE ACCOMMODATION_PRICE
---------- -------------- ---------- ------------------- ------------------- -------------------
1 1 2 520 450 350

Question:
How do I sum up the price fields, SOME PRICES ARE NOT AVAILABLE because a reservation was either made for accommodation only or flight only, hence both values will not be present always and this is where the issue lies
DEPART_FLIGHT_PRICE RETURN_FLIGHT_PRICE ACCOMMODATION_PRICE
Furthermore:
I wish to insert or update the SUM of those three values into a SUBTOTAL in the reservation table, perhaps by using select into or update, I have spent a whole day trying to do this but my skills are limited. any help will be greatly appreciated.

And the following statement is to update the reservation table.
Thanks to Leigh Riffel from DBA stackxchange for the following code
UPDATE HOLIDAY_RESERVATION R SET SUBTOTAL =
NVL((SELECT F.FLI_PRICE FROM FLIGHT F WHERE F.FLI_ID = R.IN_FLIGHT_ID), 0) +
NVL((SELECT F.FLI_PRICE FROM FLIGHT F WHERE F.FLI_ID = R.OUT_FLIGHT_ID), 0) +
NVL((SELECT AC.ACC_PRICEPN FROM ACCOMMODATION AC WHERE AC.ACC_ID = R.ACC_ID), 0);
Now the subtotal is populated with the values obtained from the sum performed above >>

10 323 19 18-FEB-12 20-MAR-12 21-APR-12 19 450
Subsequently the code was added to a trigger (which was the original intention)
CREATE OR REPLACE TRIGGER HR_SUBTOTAL
BEFORE INSERT OR UPDATE ON HOLIDAY_RESERVATION
FOR EACH ROW
BEGIN
SELECT
NVL((SELECT F.Fli_Price FROM Flight F WHERE F.Fli_ID = :new.In_Flight_ID), 0) +
NVL((SELECT F.Fli_Price FROM Flight F WHERE F.Fli_ID = :new.Out_Flight_ID), 0) +
NVL((SELECT AC.Acc_PricePn FROM Accomodation AC WHERE AC.Acc_ID = :new.Acc_ID), 0)
INTO :new.Subtotal
FROM dual;
END;
/
For the SUM, assuming you want to treat NULL values as 0, you'd just need to do an NVL on the numbers
NVL( DEPART_FLIGHT_PRICE, 0 ) +
NVL( RETURN_FLIGHT_PRICE, 0 ) +
NVL( ACCOMMODATION_PRICE, 0 )
As for the UPDATE, it sounds like you just need a correlated UPDATE statement.
UPDATE reservation r
SET subtotal = (SELECT (SELECT NVL( DEPART_FLIGHT_PRICE, 0 ) +
NVL( RETURN_FLIGHT_PRICE, 0 ) +
NVL( ACCOMMODATION_PRICE, 0 )
FROM (SELECT RESV_ID,
BOOKING_CUS_ID,
ACC_ID,
(SELECT F.FLI_PRICE
FROM FLIGHT F
WHERE F.FLI_ID = R.IN_FLIGHT_ID) AS DEPART_FLIGHT_PRICE,
(SELECT F1.FLI_PRICE
FROM FLIGHT F1
WHERE F1.FLI_ID = R.OUT_FLIGHT_ID) AS RETURN_FLIGHT_PRICE,
(SELECT AC.ACC_PRICEPN
FROM ACCOMMODATION AC
WHERE AC.ACC_ID = R.ACC_ID) AS ACCOMMODATION_PRICE
FROM dual));
You are asking:
How do I sum up the price fields, as you can see some of them can have nulls.
DEPART_FLIGHT_PRICE RETURN_FLIGHT_PRICE ACCOMMODATION_PRICE
Just enclose them in NVL function as follows:
NVL(DEPART_FLIGHT_PRICE, 0)
and then sum them up.
For the second part, what you need is a MERGE statement. A good example is at http://www.oracle-developer.net/display.php?id=203
