I have a table with products (xPRODUCT), dates (xDATE) and parameters (xPARAMETER). Now I want to calculate the rolling 12 month average of the parameters over all products for all dates. I tried this:
select xDATE, avg(xPARAMETER) over ( order by xDATE range between numtodsinterval(365,'day') preceding and current row )
select TO_DATE( TO_CHAR(CAST((B.EOAWDTTM_MODIFIED) AS TIMESTAMP),'YYYY-MM-DD-HH24.MI.SS.FF'),'YYYY-MM-DD') from PS_SR_EX_ER_AW_VW B where rownum < 5
and It gives me the error
ORA-01830: date format picture ends before converting entire input string 01830. 00000 - "date format picture ends before converting entire input string"
Our data centers resides in different zones and we would like to store the date and time information in GMT format and it should aware of daylight savings.

i have data in date format for in time actually it should be 9:30 am and out time at 2:30 pm
SELECT MIN(IN_TIME) AS IN_TIME,MAX(OUT_TIME) AS OUT_TIME FROM EMP_ATND_DETAIL AS ET, EMP_ATND_INFO AS EAI WHERE ET.EMP_ATND_INFO_ID=EAI.EMP_ATND_INFO_ID AND ATND_DATE = '2006-10-25' AND EMP_ID =24
how to get data from a Table in Date and Time format? Curently I'm using To_TIMESTAMP for a date range.
Here is the code Snippet -
Select * FROM TABLE_Name WHERE COUNTRY= 'IN' AND CALC_DATETIME between TO_TIMESTAMP('2013/06/05', 'YYYY/MM/DD HH:MI:SS') AND TO_DATE ('2013/07/08', 'YYYY/MM/DD HH:MI:SS')
when I select I have to using AND creation_dt>='17-JUL-12' is there a way to change my select to creation_dt='17-JUL-12' ? on meantime my local format is 18-JUL-12(18-JUL-12) is thee anything I can do?
I want to reset my date to this format: 12/31/2012 11:59:59 PM - see code below:
DECLARE v_latest_close DATE; BEGIN v_latest_close := TO_DATE ('12/31/2012 23:59:59 ','MM/DD/YYYY HH24:MI:SS'); DBMS_OUTPUT.PUT_LINE('The new date format is : '|| v_latest_close); END;
the code above displays only : 12/31/2012 instead of 12/31/2012 11:59:59 PM
How To Calculate Average in Forms 6i for example a summary column named (Amount = 5000) and i want to calculate 15% average of this amount i want to calculate it like summary column .
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've some database in 11.2 RAC on AIX.I was analyzing the root causes of eviction.Looking AWR Report before the reboot I see:

Do you think these value ar high? This is vmstats at the time of reboot:
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.
I have to procedure that computes number of project, and average working hours of employees where employee id is passed as a parameter to the procedure. If the average working hours is less than 10 then employee's salary remain the same, otherwise check if number of project is less than 4 then 5% of salary, else 10% of salary is added to the salary.
I want to write a sql qeuery to get result similar to expected average column as shown in sheet.
Record can be uniquely identified by columns ID, PRODUCT and OFFICE. I want to calculate average for each date considering the same record does not exists earlier i.e. I want to consider the latest vote while calculating average. E.g.
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)
I need to calcaulate the salary avarage for three days prior, leaving the current row. That should happen to every row moving back words.I have given all the details.

I have a problem related with hierarchical queries, I have this tree. - a / b c / | 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: WITH tree AS ( SELECT 'd' child, 'b' parent FROM dual UNION ALL SELECT 'e' child, 'b' parent FROM dual UNION ALL SELECT 'f' child, 'b' parent FROM dual UNION ALL SELECT 'b' child, 'a' parent FROM dual UNION ALL SELECT 'c' child, 'a' parent FROM dual UNION ALL SELECT 'a' child, null parent FROM dual [code]....
I've got values for each workday of month in table. Chief said we don't load values of weekend because of space and time economy. Weekend value is copy of last workday. How do I count average for month in this case? Technical task in Excel worksheet consist of each day of month, so average value is 14 689 262,86. I should get the same result in my query. My example below shows values, 0 is workday (present in table), 1 is weekend (absent in table)..
select 12230427, 0 from dual union all select 11960157, 0 from dual union all select 12965902, 0 from dual union all select 13939736, 0 from dual
My problem is only on Some Saturday's my Oracle server's Load average goes high (more than 300 ).
-- oracle version 11.2.0.1.0 -- runs on Sun solaris 10 -- Sun fire V 440 -- Sun storEdge 3315 connected to the server.
Same setup is working find with higher volumes without any problem but only on saturday's, that too not on all saturdays, some specific saturdays the load average goes high.
At the time nothing will be processed from the application side and the cpu utilisation goes high upto 95 %.
I am sending necessary information as follows.

I´m monitoring a 11g database with OEM. I have a couple of questions regarding the Average Active Sessions chart:
- What does the line 'CPU core' means? The DB is running in a virtual server with 8 CPUs. However, the line 'CPU core' is in 1. Does it mean that Oracle is just using 1 CPU? - What represents the '99th percentile' line? The chart shows several sessions above that line, something is not working well, isn't it?
When I try to extract the date tag value from XML data, the time stored in 20120602153021 format i.e., YYYYMMDD24HHMISS format. The following statement extracts only date as 02-JUN-12 however do not extract the time part.
If I try the same in SQLplus with to_date it works however fails in PL/SQL.
XML data: <?xml version="1.0"?> <RECORD> <REGTIMESTAMP>20120601130010</REGTIMESTAMP> </RECORD>
