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.
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.
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.
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 want to find difference between the objects(tables(columns,constraints), views, sequences) in two schemas. One schema is staging and one is development . In development lot of changes are made , Is there a script or a opensource tool which will bring out the difference in columns, constraints in each table and sequences , views etc.
I want to calculate time difference b/w two time clocks, just like we calculate the date difference and answer is in days, In the same way i like to have answer in hrs,min and ss.
how to find the difference between time stamp in two variables.
Say in a java file i am getting start time and end time i am storing it in a string variables now i need to know what is the time difference of them in millisecond
Srting1 of java will give me some thing like StartTime =2012-08-01 15:14:20.36 +5:30 Srting2 of java will give me some thing like EndTime =2012-08-01 15:14:21.254 +5:30
I need to take the millisecond difference between them the code i have written in java and connecting oracle database and doing some logic's in java so i need to capture start time and end time of code.!
during application migration, i got one table from MS Access, and have situation where two events are splited into 4 columns (start: date1 time1 and stop: dat2 and time2). How to properly calculate duration between these two events, and show it in format: hh:mi ?
I have two tables tab1 and tab2 with below data Now requirement is to find difference between two table with respect to column "serial_no" which exist only in table tab1 so as per below at serial_no 2 CC4 in tab1 but CC2 in tab2 so this is different how to dump out this data
insert into tab1 values('P1','CC1',101,1); insert into tab1 values('P1','CC4',104,2); insert into tab1 values('P1','CC5',105,3); insert into tab1 values('P1','CC2',102,4); insert into tab1 values('P1','CC3',103,5);
insert into tab2 values('P1','CC1',0,101,102); insert into tab2 values('P1','CC2',101,102,103); insert into tab2 values('P1','CC3',102,103,104); insert into tab2 values('P1','CC4',103,104,105); insert into tab2 values('P1','CC5',104,105,0);
Difference in hours is supposed to be 35 but it comes as 34.When i manually find the difference in days and multiply by 24 it comes as 34.999999999 and floor converts it as 34.. But when i execute the difference between dates alone and convert to 24 it shows as 35. So when i apply floor to this, it should be 35 instead of 34 right?
For the following query, difference of the dates in minutes is 2100.. so mod(2100,60) should give 0 but it's giving 60.. Separately if if put mod(2100,60) it is giving as 0 only.
1-Shift_date shift date *used to contain shift timings 2-Attendace_datedate *used to contain employee IN timings
As you all know that shift is a setup form, where user input data once in the starting of software so the shift_date can be "01/jan/2011 16:00 pm" but attendance loads daily and attendance field data can be in this form "24/mar/2011 16:15 pm"..Now I want to calculate difference time between these two fields therefore I used this statement
SQL> Select to_char(attendance_date,'HH24:MI') to_char(shift_date,'HH24:MI') from dual;
but it is showing error: ORA-01722: invalid number...I used hours/minutes format mask in my query because you can see there is a difference of dates between these fields and it will be increase in the coming future and I need late hours and minutes.
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
We want to find out difference of data for some tables between current day & previous day. We can use query with minus operation but it will take lot of time since table size is in range from 200 to 500 GB. We have to do this exercise every day.
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.
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?
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 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.
