SQL & PL/SQL :: Dividing The Time Period Into Weeks
Dec 14, 2011
I need to divide the given time period into weeks from Monday to Sunday .There should not be overlapping of two months, for a week.Every month should start from First day of that month to next Sunday .Same thing can be done by following PL/SQL block . let me know if there is any simple way by using query instead of block .
declare
pid_from_date date := '01-JAN-11';
pid_to_date date := '31-dec-11';
ln_number number := 0;
ld_from_date date;
ld_to_date date;
begin
I am trying to break down a row of data that has nine periods that I want to enter into a table one period at a time. I am trying to use "IF EXISTS ( SELECT * FROM TABLENAME WHERE FIELD1 IS NOT NULL) THEN" through all nine fields. It keeps returning lines that have a null column as well as not null columns. if there is a better way of doing this. Here is an example of what I am trying to do:
IF EXISTS (SELECT * FROM TABLE_NAME WHERE LAST_DT9 IS NOT NULL) THEN SELECT NUMBER, 1COL9, 2COL9, 3COL9, FIRST_DT9, LAST_DT9, 4COL9 FROM TABLE_NAME; ELSE IF EXISTS (SELECT * FROM TABLE_NAME WHERE LAST_DT8 IS NOT NULL) THEN
I am writing a query where I need to get the total points the student received on assignments, this is in the grade table. I then need to divide that total from the total amount of points possible, located in the assignment table. At the end all I should see is the student_id and the percentage of the students grade.
Here is where I am so far
SELECT s.student_id, SUM(g.points)/SUM(a.points_possible) "GRADE" FROM student s, grade g, assignment a WHERE s.student_id = g.student_id AND g.assignment_id = a.assignment_id ORDER BY student_id;
However when I execute this is the error I get:
WHERE s.student_id = g.student_id * ERROR at line 3:
ORA-00937: not a single-group group function The asterisk's should be under the g I couldn't get it to line up.
I have to optimize a batch job which returns > 1 lakh records . I have a commit limit being passed . I am planning to divide the cursor records for processing as follows. If the cursor suppose returns 1000 rows and the commit limit passed is 200 , then i want to fetch 200 records first , bulk collect them into associative arrays and then bulk insert into target table.
After this is done, i will fetch the next 200 records from the cursor and repeat the processing. I would like to know how i can divide the cursor records, and fetch "limit" number of records at a time and also be able to go to the next 200 recs of the cursor next time.
From 28/AUG/2013 to 30/AUG/2013 records has to be deleted becuase thease records are two weeks old.
From 31/AUG/2013 to 06/SEP/2013 records belongs to one week and from 07/SEP/2013 to 13/SEP/2013 belongs to another week.Today is 12/SEP/2013 so from 06/SEP/2013 to 12/SEP/2013 should be existed in the table.Once date changed to 13/SEP/2013 then from 31/AUG/2013 to 06/SEP/2013 records has to be deleted.
I am posting table and insert scripts.
CREATE TABLE process_data(p_id NUMBER,CREATED_DT DATE); INSERT INTO process_data VALUES(TO_DATE('28/AUG/2013','DD/MON/YYYY'); INSERT INTO process_data VALUES(TO_DATE('29/AUG/2013','DD/MON/YYYY'); INSERT INTO process_data VALUES(TO_DATE('30/AUG/2013','DD/MON/YYYY'); INSERT INTO process_data VALUES(TO_DATE('31/AUG/2013','DD/MON/YYYY'); INSERT INTO process_data VALUES(TO_DATE('01/SEP/2013','DD/MON/YYYY');
wanna to make matrix report retrieve months year and the number of weeks from dual table it supposes to the weeks number is 52 or 53 week months and weeks on the rows please find attach pic it show what i need to do for exmple
month name: January February March April May June July August September Nov October December no of week : 1-2-3-4-5-6-7-8-9-10-11-12-13-14-15-16-17-18-20-21-22....... TO 52 week

The cross tab is to have columns 1 - 31 which sum the quantity of the article sold. Represnting days of the month.
In addition the description of the company.
I would then like to end up with 3 entries in the results for each company, but these are for summing the quantity of articles by the following periods: -
i want to find the data which has the more then one rates available for the given date. Here below i've posted a test table. how can find the products for which, there multiple dates/overlapping period is available through sql statement.
The period for contracts should be in sequential order and should not overlap and if contract does not exist for that date period, then it should return NULL.
I need to get the number of rows based on one condition for certain time period. For example, writing a query for 3(any) hrs , i need to get the output as count of rows as hourly basis. Like these:
Date Time Count 12/08/2010 16:00 234 12/08/2010 17:00 345 12/08/2010 18:00 645
"ALTER PROFILE profile_name LIMITPASSWORD_LOCK_TIME 1"means the user account will be locked in a period of one day after FAILED_LOGIN_ATTEMPTS has gone over limit.How to set PASSWORD_LOCK_TIME less or more than one day (like not full days)?
ID NAME CRT_DTE 1 AB 03/05/1992 2 EF 15/04/1995 3 CD 20/08/1995 4 GH 01/01/1999 5 UV 08/07/2001
[code]....
I want a query which splits the total time period (from min crt_dte to max crt_dte) into year ranges.For eg, lets say a range of 5 years then I need to get results like below.
In my production environment, I have a mostly working Oracle 12c Cloud Control environment, managing several database instances. On all of the databases, I am unable to use the Compare period ADDM feature ( Instance > Performance > AWR > Compare Period ADDM).
When I select that menu option, I see the message "To be able to use this feature some PL/SQL packages need to be loaded into the target database's monitoring schema, DBSNMP." I have been searching for further information in the specific packages that need to be loaded per the message, but neither Orafaq, [URL] nor Google seem to have those details.
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>
PL/SQL Extract:
CURSOR c_xml_record IS SELECT extract(value(d), '//ACTIVATIONTS/text()').getStringVal() AS REGTIMESTAMP, FROM t_xml_data x, [code].......
I have one inline view query which shows exec\ fetch : 2 sec\ 19 sec It gives 500 rows as final out put, when i give rownum<100 it shows exec\ fetch : 1 sec\ 000 sec, and i cannot use this rownum< 100 alternative as this is inline subquery of big query.
I Have three field and first field for START TIME ,Second END TIME & Third DURATION AND Putting START TIME AND END TIME i am getting duration in minutes by using code
I have a table which stores apointment start times and appointment end times. For the sake of this thread I will call them appt.start_time and appt.end_time. I then have a check in time and a check out time for the customer. The only thing is they ONLY way to distinguish between a check in time and a check out time is which one has the earlier time and which one has the later time. Obviously the earlier time will be the check and the later time will be the check out.
This is fine, however sometimes they may forget to check a person in or out and I need to determine whether the time should be insert into the check_in column or the check_out column. To do this I was thinking of comparing the time with the appointment start and end time and if it was closer to the appointment start time put it into the check_in column and if its closer to the appointment end time put it into the check_out column. But I was wondering how I would go about doing this.
The time I will want to compare against the appointment start and end time I will store in a variable called v_time and have this as part of my query, im just unsure of what way to write the query so as to check if the time is closer to the start or end time.
select asl1.agentsessionid, asl1.endtime, asl2.starttime, 127 as agentstatus from ( select asl1.agentsessionid as sessionid1, min(asl2.agentsessionid) as sessionid2 from cti.agentsessionlog asl1

As you can see from my where statement I want to compare the endtime with the startime. This query returns zero results. Is there a way to write the where statement different so I can have results?
My time zone has the offset of 2 hrs during summer and 1 hr during winter.If I want Oracle to tell me what was offset for particular day for example I want to know the offset for February 01, 2010 and August 01, 2010, is it possible?
I have an application in which time is show as . But, in the table in Oracle it is showing as 13:00. The application is taking the time from OS. OS time is 18:30 IST. Time in SYSDATE is also showing as 18:30. DBTIMEZONE is '+5:30'. what is the problem in Database and how that can be rectified to show the time as same as OS time.
We have a Oracle 10g database with RAC and Dataguard. When we look at the AWR report, the wait time shown by Oracle for this database is very high.
Service Time : 15.36% Wait Time : 84.64%
This would imply Oracle is waiting for resources 85% of the time and only processing SQL queries during 15% of its non-idle time. However when we check the OS (RHEL), the iowait is only about 10% and the CPU is 80% idle. This means that that processing horsepower is available.
As such, the results between the OS and Oracle database (AWR report) seems contradictory. OS says we have CPU/IO capacity, however Oracle says we don't.
I'm using Oracle 11g and I have a bunch of indexes and I want to check if they are being used. I just ran my workloads and now I want to see when each one was last used so I can see if it was during my timeframe or not.
After I ran my test, I found the below, but since I did not enable this, plus I have many indexes.
--Monitor an index to see if it's used alter index SAMPLE_INDEX monitoring usage; select * from v$object_usage where index_name = 'SAMPLE_INDEX'; alter index SAMPLE_INDEX nomonitoring usage;
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 )
