SELECT HISTORY_ID ,SUM(MISSED_SCHOOL) AS MISSED_SCHOOL,SUM(MISSED_SCHOOL_LAST) AS MISSED_SCHOOL_LAST FROM EMRASTHAMAHISTORYDETAILS WHERE ------ GROUP BY HISTORY_ID
There is no date column in table using sysdate alone need to retrieve last 6 month records
We have a requirement where we need to pay allowance for the employees based on their number of working days. Say for example if an employee worked from 03/Mar/2012 to 05/Apr/2012.
We have a fixed value for per month 300 Dirhams. But the Number of Days on March s 31 and Number of days in April is 30. So per day allowance for March day would be 300/31 and April would be 300/30.
We are looking for logic opr query which calculates first eh number of days in each month ( across months) and then calculate as below
Number of Working days in March is 31 - 3 + 1 = 29
Allowance A1 = (300 * 29 )/31
Number of Working days in April is 5 ( this also needs to find logical I am guess ) Allowance A2 = (300 * 5 )/30
Then A1 + A2.
The A(n) would be the total allowance where provided the number of month across.
MISSING_DATES EMPNO ---------------------- ---------- 09-SEP-12 TO 11-SEP-12 7499 23-SEP-12 TO 26-SEP-12 7499 01-sep-12 TO 30-SEP-12 7521 01-sep-12 TO 30-SEP-12 7788
I want to find the row with invalid day, month which are not matching with calendar day and month. Also the program should capture the data if the year <1900
with xx as (select 101 as ID, '24/05/1899' as create_date from dual union all select 101, '32/03/2012' from dual union all select 102 ,'30/02/2012' from dual union all select 101 , '29/02/2013' from dual
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.
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 .
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.

How to find in the oracle10g database if there is any column which is not being used at all.If the data is there in the column,how to check when was it last populated.
I am trying to find out database name for the unusable indexes thru the query; I am using dba_indexes for the index name but not sure which view I need to join with to find the db name.
We have a 2 node RAC runing on 11.2.0.2 and last night the database was totally un-responsive. when i checked the ADDM I noticed the following:
Waiting for event "cursor: pin S wait on X" in wait class "Concurrency" accounted for 98% of the database time spent in processing the SQL statement with SQL_ID "4b2epo0eaqol9".I am wondering what option do i have here? i am looking to do the following:
1) find the root cause why the database was un-responsive
2) ADDM is listing the query, what options do we have further?
How do you find the youngest user in a certain table
select a.illness_desc from uma.pc_illness a, uma.pc_patient b, uma.pc_diagnosis c where b.patient_no = c.patient_no and c.illness_code = a.illness_code and b.age = '21';
i currently have this (it also needs to display their illness which i have done) but i can do only if i cheat and see what the youngest user is, so instead of b.age = 21 i need something that will search the database and find that youngest age
I need the column name and table name which is having the particular value in the whole database.

There is one DBMSJOB i created schedule to run every day at 22:00 hrs. The jobname is IT_TO_DUM_LOADING and the job type is Stored procedure.
I queried all_source and found stored procedure does not exist in database.
SQL> select text from all_source 2 where type = 'PROCEDURE' 3 and name ='IT_TO_DUM_LOADING';
no rows selected
But i could see the job details in dba_scheduler_jobs view. I cannot use WHERE clause in dba_scheduler_jobs to restrict and find only the job row as i receive time zone error. How it is possible to view the job in dba_scheduler job view whereas i could not find the stored procedure of its in all_source?
As a part of requirement need to clean up some of database objects from database. Before cleaning up need to check for dependencies with in database and also on remote database.
Is there any data dictionary in oracle which proivides information about remote dependencies.
Any other way to get a list of remote dependencies other then manual checking.
I am having database A and database B and I am inserting into database b by selecting some records from database a using db link.Is there any way to find whether database link is being used?
