according to me, v$datafile can be use to know growth in database in terms of datafiles added in past months as per creation_time. but hows about those existing datafiles whose size has been re size more .
I have a requirement to list the data month wise dynamically where month data is also in the same table, hopefully the below posts should bring more clarity to my requirements.
I have a table with starting date and ending date.
I want to fetch monthwise days for given two dates
IE starting 25/12/2009 ending 25/03/2010
Result should like below.
Dec-09 7 Jan-10 31 Feb-10 28 Mar-10 25
I have tried this but it is not giving me the result which want..
select to_char(thedate,'mon-yy') mnth,count(to_char(thedate,'mon-yy')) days from (SELECT TRUNC(to_date('25/12/2009','dd/mm/yyyy'),'Y')+ROWNUM-1 THEDATE FROM ( SELECT 1 just_a_column FROM dual CONNECT BY LEVEL <= 366
case 1 code start month end month winter march march summer april january spring feburary feburary
case 2
winter January January summer february september spring october december
and if i am trying to enter again start month and end month . i should validate if the month i am giving is already present in the table for any of the season
i want a do the validate with a query so that i will not enter duplicates.
I am in need of a clarification regarding the file size growth in Physical Standby Database.Say we have 150 GB size of LIVE DB and we have created the same as in STDBY(150 GB).Will there be a growth in STDBY DB datafiles with respect to the LIVE DBOR only the logs are applied currently to the STDBY and the changes will only be reflecting when there is a switchover or failure scenario??
We load large amount of data into multiple tables using sqlldr. Amount of data that we need to load varies according to the situation. We want to estimate the tablespace usage growth due to this data load, so we can verify/extend the tablespaces before the data load. Though, setting to autoextend will work in this case, We want to avoid extending the tablespace during sqlldr executing due to performance.
Our initial attempt was to note the tablespace size before and after executing the sqlldr and use the delta. But this delta was not consistent in different environments for the same amount of data. Different environments mean different oracle servers, different existing sizes of tablespaces, One data file Vs multiple data files etc.
How do we reliably estimate how much tablespace we need for the given amount of data?
I need tablespace name,tablespace total size and used size of every tablespace for my 106 databases. bcz I am planning to prepare tablespace growth report for my 106 dbs. If I have the 2 months data from now in xl sheet, then I can predict the growth rate of every tablespace accurate almost.
it is not a easy task to fill the space detail manually in xl sheet everyday.Hence I need some mechanism to do this activity automatically.
I know we can collect this detail in a csv file every day while running the script. but is there any mechanism to store these detail in a particular xl sheet one by one column automatically?
Using 11gR2, windows 7 client machine. I need to update the table missing_volume (below), where I need to calculate the estimated_missing column. The calculation of estimated_missing column for current month needs previous month numbers (as commented inside the code below). I want the output like the first table. Notice the records start from January, hence estimated_missing for January can't be calculated, but for the the rest of the months it can be done by simply changing 'yr' and 'mnth' (commented inside the code towards the end).
yr mnth location volume actual_missing expected_missing estimated_missing --------------------------------------------------------------------------------------------------------------------------------- 2013 January loc1 48037 24 57 2013 February loc1 47960 3660 53 24 2013 March loc1 55007 78 57 28 2013 April loc1 54345 72 58 77The code:
UPDATE missing_volume g
[Code]....
The code does calculate correct number for 'estimated_missing' as I run the code for each month, but the problem is while updating the current month it also erases the record for previous month. E.g. as can be seen below, after I updated April the column only has the record for April, previous month record is gone, similarly updating March removed February, etc. I can't understand why it's happening!! Here is the output I get:
yr mnth location volume actual_missing expected_missing estimated_missing --------------------------------------------------------------------------------------------------------------------------------- 2013 January loc1 48037 24 57 2013 February loc1 47960 3660 53 2013 March loc1 55007 78 57 2013 April loc1 54345 72 58 77
why it's happening (I mean where is the flaw in the code) and how to get the desired output (first table).
I need for each date sum the values from the begin of the year to present date. In January I will have the value of this month, on February I must sum the value of this month and the value of the month before, and so on, at the end of the year.
Date input
SELECT ID_CLIENT, DT_REG, VAL FROM ( SELECT 1 as ID_CLIENT, TO_DATE('20100101', 'YYYYMMDD') as DT_REG, 200 as VAL FROM DUAL UNION SELECT 1 as ID_CLIENT, TO_DATE('20100201', 'YYYYMMDD') as DT_REG, 100 as VAL FROM DUAL UNION SELECT 1 as ID_CLIENT, TO_DATE('20100301', 'YYYYMMDD') as DT_REG, 200 as VAL FROM DUAL UNION SELECT 1 as ID_CLIENT, TO_DATE('20100401', 'YYYYMMDD') as DT_REG, 150 as VAL FROM DUAL UNION SELECT 1 as ID_CLIENT, TO_DATE('20100501', 'YYYYMMDD') as DT_REG, 100 as VAL FROM DUAL UNION SELECT 2 as ID_CLIENT, TO_DATE('20100101', 'YYYYMMDD') as DT_REG, 100 as VAL FROM DUAL UNION SELECT 2 as ID_CLIENT, TO_DATE('20100301', 'YYYYMMDD') as DT_REG, 220 as VAL FROM DUAL UNION SELECT 2 as ID_CLIENT, TO_DATE('20100501', 'YYYYMMDD') as DT_REG, 500 as VAL FROM DUAL UNION SELECT 3 as ID_CLIENT, TO_DATE('20100201', 'YYYYMMDD') as DT_REG, 150 as VAL FROM DUAL UNION SELECT 3 as ID_CLIENT, TO_DATE('20100501', 'YYYYMMDD') as DT_REG, 100 as VAL FROM DUAL);
In oracle query can i want find out how many day wise count for a year days (for example how may sundays, mondays, tuesdays, wednesdays ,thursdays,fridays,saturdays) in a given year (we can give the start day of the year and the end day of a year).
example ---------- jan sun-5 mon-4 tue-5 wed-5 thu-5 fri-4 sat-5 feb ------------do--------------------------------- like this for all 12 months at a single query.
select in1.empid,in1.atttime,out.atttime from (select empid ,atttime from attend where status=1 and to_char(atttime,'mmyyyy')='022012' order by empid,atttime desc) in1, (select empid,atttime from attend where status =0 and to_char(atttime,'mmyyyy')='022012' order by empid,atttime desc) out where in1.empid=out.empid and in1.empid='02256' order by in1.atttime,out.atttime
But this query do .one value relation with all column.means first february in time with all out time.
If a particular department has 10 employees it should have data upto emp_name_10,if department has only 5 employess it should data upto emp_name_5 and so on.I came up with below approach, in this approach I need to create new table to store the data in row wise.
In my actual requirement 4 tables needs to be joined and 2 of the tables are very large.Is there any other approach without creating a new table, something within pl/sql.
drop table emp_dept; create table emp_dept(deptno number,dept_name varchar2(100),emp_name varchar2(100),hire_date date,seq_cnt number,total_cnt number); insert into emp_dept
OS : Windows 2003 DB : 10.2.0.4 I am doing capture and replay first time.I want to take 2 captures at a time. 1st capture for 2 schemas and 2nd capture for other schemas.Is it possible?I have searched on internet but didn't get any clue about it..
Web page that retrives data from SQL database and display it to the user in well formatted manner. Data retrieved depend upon criterias selected by the user. But sometimes data retrieved is very large. I want to display records to the user page wise, i.e. 100 records on first page and next 100 records displayed when user clicks next button. This means only 100 records should be retrieved when user first select search criteria, next 100 records retrived when he clicks next button and so on, as to reduce data transferred from server to client. how to achieve this by using single sql query as soon as possible.
Report have one parameter para name depatwhen i go to generate pdf it will ask me which dept if i pick 10 then they generate one pdf if i pick All Dept then they generate again one pdf i need seperate pdf like 10,20,30,40 generate four pdf files
how can i compute row wise multiplication for each unique value of id. I am trying to get the output as showing id and their respective results after multiplying the corresponding values.
CREATE TABLE mult_tbl( id NUMBER, val number ); insert all into mult_tbl values (1,2) into mult_tbl values (1,3)
Is there any way to capture the version wise objects (Packages) information from the oracle data base.
Ex : I have package P1 which was created on 01-NOV-2012 with version 1 . After 10 days same package has been updated version 2 with some enhancements.Like that the package will be updated according to the latest requirement.
Now I need to capture the total audit trail history of the package with version wise specific changes and when changes has been occurred hoe can I achieve this?
