PL/SQL :: Find Duration By Subtracting Start And End Time?
Jun 25, 2013
Version: 11.2 I am not an SQL expert. I am trying to subtract the start time and end time and thereby find the difference between these two times. In the below example , the difference between start_time and end_time is around 52 minutes (6:15 PM to 7:07 PM)I tried some stuff to find the difference below. But it didn't work out .
SQL> create table t (start_time date, end_time date); Table created. SQL> desc t Name Null? Type ----------------------------------------------------------------- -------- --------------------- START_TIME DATE END_TIME DATE SQL> insert into t values (to_date('24/JUN/2013 18:15:42', 'DD/MON/YYYY HH24:MI:SS'), to_date('24/JUN/2013 19:07:54','DD/MON/YYYY HH24:MI:SS')); 1 row created. SQL> commit; Commit complete. SQL>SQL>SQL> select * from t; START_TIME END_TIME-------------------- --------------------24 Jun 2013 18:15:42
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
[code]...
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?
formatting the data.I want to group the below table data based on the Grade column for a header_data with start_time and end_time displayed in range. I was trying with group by, partitions etc but no luck. I use version 10gr2.
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?

Since the date format does not contain AM or PM in it ... while subtracting time values crossing midnight the value goes in negative .... How to subtract two date strings with out AM or PM values to get a positive value ?
My problem is that I am working with a balance (Infor/WorkBrain - Time & Attendance) I have a balance called Bank Holiday(bal_id 10044). Every holiday that an employee works, he is allowed to take another day off in lieu of the day he worked. The employee has up to twelve months to take that holiday.
My job is to figure out when he worked that holiday (not a problem) and send an email/note at the 11 month mark and notify the employee and supervisors that said employee has 1 month to use his banked holiday.
My problem is the data/constraints I am working with. I can tell what day the holiday was based on a time code (EBLOG_MESSAGE) and EBLOG_DELTA shows a positive 1. I can also tell when the employee has used a bank holiday (EBLOG_DELTA is -1) and EBLOG_MESSAGE = FR_HWO.
But how to I perform the deduction so that I get four most current dates. Meaning since my first date that the employee gets for a holiday wokred is 6/3/2010 but the employee used a bank holiday on 8/31/2010. So I want to display the dates 7/1/2010, 7/27/2010, 8/1/2010 and 10/15/2010.
My preference would be not to add anything new to this table as it is a core table for Infor/WorkBrain.
I am having a problem when calculating dates in a package usiong Toad. I have my function :
FUNCTION PORTFOLIO_MEMO_RPT_Sql( schema_name IN VARCHAR2 , select_business_date IN DATE ) RETURN VARCHAR2.....SELECT DISTINCT Case when NVL(TO_DATE(''09/24/2013'',''MM/DD/YYYY'') - DECODE(mn.Active, 1, mn.DueDate, sc.DueDate ),0) = 0 then ''0Days'' when NVL(''' || select_business_date || ''' - DECODE(mn.Active, 1, mn.DueDate, sc.DueDate ),0) = 0
then ..... when I give it my variable from outside , it is not working......but when I use a date inside, it works. I call my function from outside like :
SELECT * FROM TABLE ( FI_rpt.Fi_Rpt_Pkg_loan.PORTFOLIO_MEMO_RPT (sys_context('userenv','session_user'),TO_DATE('09/24/2013','MM/DD/YYYY')) )
Is it possible to generate AWR report for the duration of 5 min? As we know that snapshots are generated for every 1 hour, which we specified in parameter.
By changing the parameter to 2 min, what could be the impact on database?
I'm trying to install Oracle 10g Enterprise Ed. (on Windows 2003 Std. Ed) and I get some errors:
First “Fail to start OCR” I press "continue" and the installation continue. Next “Operative System Error when start OracleCSService” and when I press "continue" the installation finish.
At the end of installation, It seems like Oracle DB is Ok, but not really...I can't connect to database from Enterprise Manager and the OracleCSService is in "Starting mode".
I wanted to calculate the time variance dynamically as below.I have one table called process_status where we can see the process name, start time, end time and the status .
1. Now i wants to calculate the duration(end_time - start_time) in hh:mi:ss format and i got the output using below query.
I got currect oupput but i am stuggling with the below step.
2). Actually the process expectaiotn time is 2 hours only(fixed time). Now i wants to calculate variance b/w expected time and the duration time(end_time - start_time)
i.e variance = expected_time - (end_time - start_time ) ; here expected time is 02:00:00(fixed).
I tried using with to_char and to_date function but no luck.
I want to know how I can find which query is taking more time , for example some query's are run from unix, java and from toad,sqlplus. and one query is taking much more time to execute, so how i can get that query and all the details.
in the above, for job 1 ,on 19/08/2010 the time difference should be calculated as
01:23:12-00:56:00 and the difference should be in minutes.
for end_time. i can't take the substring as the length of the date varies for 19 and 7. In case of start date, the time has to be in format, hh:mm:ss, to calculate the difference.
say for example there is a column called 'date_txn' in a table .When i select that particular column it display output as 'June 2013'.But i want output "with date and time".
I have a table which is getting populated from a source. I dont have a time-stamp column in the table. Is there anyway to find the time when a record was inserted into the table?
I have 10 users in my database, I need to find the time at which a query is fired by any of the users in the database. provide the query for this? I think i have to use V$sql,v$sqlarea or v$sql.
I am using imp / Schema level. Dump file contains 3 schemas with 120 GB size.Imp is running now. How to find completion time. So that I can inform to application developer about activity completion time.
here we have an scenario where we want to find out all the sql statements that are executed in a particular time. The sql statements are executed via our application. I tried in awr report but it shows only the sql query which has taken long time to execute. and i even tried in V$session and V$sqlarea. how to view the executed sql statements in a particular session/current session
Is there any oracle dictionary view which captures the queries being run by users on the database and time taken to execute those queries?We need to find out the OS user not the database user since we have to identify the users who are executing long running queries.We require this basically to monitor the long running queries on the database.
Is there any way to find out the division between the time taken for query parsing, creating execution plan and actual data retrieval seperately? If I enable 'set timing on' I see the elapsed time which is the total time taken for all these 3. Some of my queries are taking long time when I run it first time and so want to know what is it taking long? is it the parsing or creating the execution plan, if so what can I optimize.
Oracle Database Version : 9.2.0.8.0 Some of the datafiles status have been changed to 'RECOVER', because the datafiles are physically missing.
Now, how can i find that when (timestamp) the status of the datafiles have been changed, as i am unable to find when the datafiles have been physically lost?
Please consider both the case :
1) when the database is in ARCHIVELOG Mode. 2) when the database is in NOARCHIVELOG Mode.
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].......
