I'm trying to build a query capture the below information. Table looks something like below .
RoomSubjectStudentsA1Science10A1Maths20B1Science15B2English25C1Deutsch20A1French15C1English10
How can i write a query so that i takes the average of students in each room and display the output? I need to write a query so that it also picks up any new rooms and students added. Average is sum of total students in room by number of times each room is specified.
eg: A1 is listed 3 times a the result would be 10+20+15 divided by 3.
A1 B1 B2 C115 15 20 15
My table has two date columns EFF_DT which is the start date and TERM_DT is the end date. The EFF_DT of the next record should be the next date of the TERM_DT record.
My table looks like this.
Input Table:
-----------
CK_IDPI_IDEFF_DT TERM_DT
Mem1ABC1-Jan-1331-Mar-13
Mem1ABC1-Apr-1331-May-13
Mem1ABC1-Jun-1330-Sep-13

Mem1ABC1-Jan-1431-Mar-14
Mem1XYZ1-Apr-1430-Jun-14
Mem1XYZ1-Jul-1431-Dec-14
Expected Output:
----------------
CK_IDPI_IDEFF_DT TERM_DT
Mem1ABC1-Jan-1330-Sep-13
Mem1ABC15-Oct-1331-Mar-14
Mem1XYZ1-Apr-1431-Dec-14
In the fourth record, the effective date should be 1-Oct-13 which is the next date to the last TERM_DT 30-Sep-13.As the is the break in the date, the output should show 15-Oct-13 sa the second start date.
Note: Refer to the PI_ID columns, there is a break in the date for the sale PI_ID 'ABC'.
Here I am trying to generate a pseudo column, so that the table with the pseudo column looks like as shown below. and I can use first_value and LAST_value by partitioning on the pseudo column to get the desired output.
1) CNT_VAL is the pseudo column:
-----------------------------
CK_IDPI_IDEFF_DT TERM_DT CNT_VAL

We've got a query which returns one row, but uses an IN statement. The IN statement links to more than one row in the subquery. When we use a combination of DISTINCT and an ANALYTICAL sum, the sum total is multiplied by the number of rows in the sub query. Remove the DISTINCT and we get a single value.
A simplified example of the problem is below.
I can't see how a query which returns a single row then returns multiple values with the addition of a DISTINCT. Removing the analytical sum also provides a single row, but we need this in the actual query we're running. So it seems to be some combination of DISTINCT, ANALYTICAL SUM and IN query is causing multiple values to be returned.

I am having a table with 5 lakhs transactions. I want to fetch the last balance for a particular date. So i have have returned a query like below.
SELECT curr_balance
FROM transaction_details
WHERE acct_num = '10'
[Code]...
This has to be executed for incrementing of 12 months to find the last balance for each particular month. But this query is having more cpu cost, 12 times it is taking huge time. how to remodify athe above query to get the results in faster way using analytical query. Whether this can be broken into two part in PL/SQL to achive the performance. ?
I'm posting below test case in which I'm not able to understand output for LAST_VALUE function. I'm expecting maximum value for the salary in a department. Because I'm partitioning by department and ordering a partition as assending so being last value it should give me maximum value within a partition i.e. department in this case.

Is there any way to apply the restriction on analytical functions, just like WHERE and HAVING .AS we know that we can apply the restriction on table by using WHERE and grouping functions by using HAVING clause .
For Ex: Departments wise count including all employees record :

Here is the test-table creation script:
CREATE TABLE TEST1 (AGG_DATE DATE, COL1 NUMBER(9), COL2 NUMBER(9), COL3 NUMBER(9));
Here is the test-data population script:
insert into TEST1 (AGG_DATE, COL1, COL2, COL3)
values (to_date('01-01-2012', 'dd-mm-yyyy'), 1, 1, 1);
[code]....
The problem is when I wrote an analytical query, it is giving the BEGIN_DATE and END_DATE by taking all the partition values together and so instead of the values above, it is creating an answer as follows:
Wrong Dataset
BEGIN_DATEEND_DATECOL1COL2COL3
1/1/20121/8/2012111
1/1/20121/8/2012111

1/4/20121/11/2012222
1/4/20121/11/2012222
[code]....
Only the last row is correct. What can I do to get the right answer as I know am falling short? Here is my current query:
SELECT MIN(AGG_DATE) OVER(PARTITION BY COL1, COL2, COL3) BEGIN_DATE,
MAX(AGG_DATE) OVER(PARTITION BY COL1, COL2, COL3) END_DATE,
COL1,
COL2,
COL3
FROM TEST1;
I have simplified this for ease of understanding. I have a Data column and a Month_ID column like this:
Values Month_ID
--------- -------------------------------------------------------
AAA 1
BBB 2
I split this out to values per year like this
Value_2011 Value_2012 Month_ID
-------------------------------------------------------------------------
AAA 1
BBB 2
Now i am trying to get the max(Value_2011) keep (dense_rank Last order by Month_ID) but i get a NULL. I can understand its because the Month_ID accomodates all years but i only need it to look at Month_ID for 2011 and return me the last dense_rank value, how can i achieve this?
I tried a couple of different methods like Last_Value() but i have group by in my original statement and i think analytical functions dont like GROUP by if they are not part of it. How can i achieve this?

I have a table with the following format and data
Serial no exp_Date exp_type exp_amount
1 01-nov-2012 Rent 10000
2 02-nov-2012 gas 250
3 02-nov-2012 insurance 9500
.

I want to create a sql output for a yearly view in the format
exp_type JAN FEB MAR APR ..... NOV DEC TOTAL AVERAGE PROJECTED
Rent 10000 10000 10000 10000 10000 10000 120000 10000 120000
gas 250 250 250 250 250 250 3000 250 3000
.
.
Now a couple of things in this
1. the average gives the average for the year, so lets say its start of 2013 and we are in feb, there will not be any values for the remaining months, so it should do the average for that exp_type for Jan and Feb based on the exp_amount entered against that type and show what is the expected average. Similary, projected will that average amount and mulitply it by 12 to show the exp amount expected based on current expenses
I was able to come up with the following sql to get the sum based on months, was not sure about average, total and projected
SELECT exp_type
, SUM (CASE WHEN to_char(exp_date,'Mon') = 'Jan' THEN exp_amt END) AS Jan
, SUM (CASE WHEN to_char(exp_date,'Mon') = 'Feb' THEN exp_amt END) AS feb
, SUM (CASE WHEN to_char(exp_date,'Mon') = 'Mar' THEN exp_amt END) AS Mar
, SUM (CASE WHEN to_char(exp_date,'Mon') = 'Apr' THEN exp_amt END) AS Apr
, SUM (CASE WHEN to_char(exp_date,'Mon') = 'May' THEN exp_amt END) AS May
[Code]....
getting the correct avg, total and projected fields also in the same sql?

I need to calculate the sum of values over a period of exactly one month (including the current row). Now if I use a windowing clause of "range between interval '1' month preceding and current row", the total period length is 1 month plus one day (being the day in the current record).
Basically, I want to sum over a period starting at "add_months(startdate, -1) + 1" up until startdate of each row.
drop table window_tst;
create table window_tst
( id number primary key
[Code]....
So instead of having 01-feb going back to 01-jan, it should only include 02-jan till 01-feb
I could of course recalculate the period length back to a number of days for each row, but that is not really what I would prefer, as it would make the code rather unreadable.

Average till date 1/1/2011 is Avg (2, 4, 3) = 3 (as no repeating vote value exists)
Average till date 2/1/2011 is Avg (4, 3, 5, 3) = 3.75 (excluding vote value 2 as 122_UK_LONDON was provided his vote earlier, so considered latest vote value i.e. 5)
Average till date 3/1/2011 is Avg (3, 5, 3, 6, 5, 8 ) = 5 (excluding vote value 2 for 122_UK_LONDON and vote value 4 for 967_Europe_London)

/ |
d e fI need to calculate an average per node but using always the child's results for example: Only leafs will have values:
d = 10
e = 20
f = 30
c = 40So the expected result is:
d = 10
e = 20
f = 30
c = 40
b = (10(d) + 20(e) + 30(f)) / 3 (number of child nodes) = 20
a = (20(b) + 40(c)) / 2 (number of child nodes) = 30.
I have tried with recursive queries, hierarchical queries, I guess it's possible with model too but I can't produce the exact results that I need. Maybe in fact there is a very simple solution but I cannot figure it.
Here is an auxiliary WITH that you can use to start your tests:
