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]....
and the values will be for one value of LVL1_NM there will be different LVL2_NM values like wise for each and every value of LVL2_NM column there will different values in LVL3_NM column like wise for LVL4_NM is there any way to get the results as per their relation ships.
Getting below error while select statement execution. I have searched in google and oracle But didn't find satisfication answer. how to resolve this issue on database level.
Oracle Versin: 11.2.0.2 Error: ORA-29275: partial multibyte character
I have an APEX page with a master and a detail. The master is a classic report with a column link which sets an hidden item on my
page:javascript:$s('P280_DAK_ID','#DAK_ID#');
I have a dynamic action which reacts on change of the item P280_DAK_ID.It then refreshes the detail region which is a PL/SQL region with the following:
begin apex_p280.show_xml(p_dak_id => v('P280_DAK_ID'));end;
This prints a few pieces of text to the screen, nothing special. Everything works except the refresh of the detail region.This is due to the fact that the new value of P280_DAK_ID is not in the session state yet. So my question is: what would be a nice solution to set the item in the session state without a submit? With a normal region I could fill in 'Page items to submit', but with a pl/sql region I can't.
I have a complex sql query that fetches 88k records. This query uses a global temporary table which is the replica of one of our permanent tables. When I do Create table..select... using this query it inserts only fewer records. But when I make the query point to the permanent table it inserts all 88k records.
1. I tried running the select query separately using temp and perm table. Both retrieves 88k records.
2. From debugging I found that this problem occurred when we were trying to perform a left outer join on an inline view.
However this problem got resolved when I used the /*+ FIRST_ROWS */ hint.
From my limited oracle knowledge I assume that it is the problem with the query and how it is processed in the memory.
I am trying to import the schema into 11g database, which i took on Oracle 9i database. While import is running, data file is full as auto extension was not enabled.
I got the following error:
. . importing table "WO_GL_ACCOUNT_SUMMARY" IMP-00058: ORACLE error 1653 encountered ORA-01653: unable to extend table PWRPLANT.WO_GL_ACCOUNT_SUMMARY by 1024 in tabl espace PWRPLANT IMP-00018: partial import of previous table completed: 7055845 rows imported.
Then I increased the datafile size and finally Import terminated successfully with warnings. At this point, I want to know whether WO_GL_ACCOUNT_SUMMARY Table was imported with out missing any rows .
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 )
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 .
how to calculate the average of the time in th e HH:MM:SS format stored database table.. column contains hundreds of time values and need to table the avergae of it
my col look like,and column is declared as timestamp(6).
MY COL ------ 1:13:00 1:06:00 0:43:00 0:47:00 0:32:00 0:19:00 0:39:00 0:46:00 0:56:00 1:39:00
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 want to convert this query to just return a single line for -cidterr.rnam, cidterr.rnum, cidterr.tnam, cidterr.tnum
With an average sum by week. Similar to how if I did a sum by week from the original query and placed the results into an excel pivot and said show total as average.
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?
I was executing following query and it was taking about 20 sec's to execute before i decided to create B-Tree(Normal) index on column DeliVery.
Select DeliVery,Code,Sum(Units),Sum(Loads),Count(units), Count(Loads) Where
[code]...
After creating B-Tree index on Column Delivery the execution time has been reduced to one second ,thats what i wanted. But If i create Bitmap index on the same column then execution time is not getting reduced and is still same around 20 sec.I think theoratically "Delivery" column is the right candidate for Bitmap index? whether should i create bitmap index or stick with B-Tree index?
