SQL & PL/SQL :: How To Get Date In Seconds
Oct 23, 2012
I have a date field which is passed as in parameter defaulted to sydate With the passed date as input I need to run an eod for every 15 mins by calculating
v_sdate := TRUNC ( in_sdate
- (MOD (TO_CHAR (in_sdate, 'MI'), 15) * 60)
/ (24 * 60 * 60),
'MI'
);
v_edate := TRUNC (in_sdate, 'MI');
Using the above v_sdate and v_edate I am calculating the start date and end date and compare these in my final select query.Now in case of rerun of old date, I am calculating start date as : v_sdate := TRUNC (in_sdate, 'MI') - 15 / 1440;
But in the above calculation, I am not considering seconds, but I need to consider those also, because say I ran the eod at 23-oct-2012 12:23:13 then my start date in case of re run should start from 12:23:14 secs , how can I achieve that?

I'm using Apex 4.2.1 against Oracle 11gR2 and mod_plsql.create a date picker item that allows users to select seconds as well as hours and minutes.
I have searched this Forum and see that others have asked this question. The answers have all been "No". However, I've seen no such question since version 4.1 has been released, and so, am hoping there now is a way to do this.
I have adjusted the Date Format field to be "DD-Mon-YYYY HH24:MI:SS", both under the date picker item itself as well as under the "Global" parameters section of my application. All to no avail. The date picker shows only hours and minutes for the time portion.

I have a date column in a table, I need to fetch records from 27:11:11 00:00:10 to 30:11:11 00:00:10 (DD:MM:YY HH:MI:SS). i.e between seconds/min/hrs.
expecting Something like this,
SELECT * FROM TABLENAME WHERE MODEDATE BETWEEN
TO_CHAR('27/11/11 00:00:10','DD-MN-YY HH24:MI:SS') AND
TO_CHAR('30/11/11 01:10:10','DD-MN-YY HH24:MI:SS')

I have to create the following table. The fields Trend_Date, Price and Trend are already given. I have to calculate the field permanently and to insert the value in this permanent table.
Fields:
The field price belong to the value of a product during the trade.
The field trade_date belongs to the moment of the trade.
The field trend belongs to the future behavior of the the price. Here, the price of the present moment is compared to the following price (possible characteristics: 'UP', 'DOWN', 'STABLE').
The field permanently belongs to the time (in seconds) how long the value of the field Trend_Date (depending on the price) is still true.
For example:
Row 1: The trend in row 1 is 'UP' and it has a price of '11'. Until row 3 this remains true (the price is greater or equal to 11). In this case, the difference between row 1 and row 3 are 9801 (rounded) seconds.
Row 2: The trend in row 2 is 'DOWN' and it has a price of '12'. This remains true till to the end (the price is never greater than 12) In this case, the difference between row 2 and row 11 are 97346 (rounded) seconds. To calculate the 97346 seconds the field has to consider that between row 2 and row 11 are two days. There will be no trade between 18:00 and 07:00 o'clock. This belongs to 7 hours for each days, in seconds (2*46800) 93600.
-> 190945-93600 = 97346s
Row 6: The trend in row 6 is 'UP' and it has a price of '5'. This remains true till to the end (the price is never smaller than 5) In this case, the difference between row 6 and row 11 are 65729 (rounded) seconds. To calculate the 65729 seconds the field has to consider that between row 65729 and row 11 are one days. There will be no trade between 18:00 and 07:00 o'clock. This belongs to 7 hours for each days, in seconds (1*46800) 46800.
-> 112528-46800 = 65729s
Row 9: The trend in row 9 is 'STABLE' and it has a price of '8'. Until row 10 this remains true (the price is equal to 8 ). In this case, the difference between row 9 and row 10 is 14418 (rounded) seconds.
Row 11: Is empty because there are no values to compare.
Example Table
TRADE_DATE --PRICE --TREND --permanently
02.01.13 11:21:42,720000000--11--UP--9801
02.01.13 12:44:03,236000000--12--DOWN--97346
02.01.13 14:05:03,845000000--11--DOWN--92485

Our database was generating archivelog(50MB) every 30seconds! I think this is not normal because what I did is open our database, I was the only one who is connected, I'm not running anything, but our database is still generating archivelogs!
Our redo logs: 6groups 3members.
This are the things I saw on our alert logs:
- advanced to log sequence
- cannot allocate new log, sequence
- checkpoint not complete
- private strand flush not complete
What I did is change the log mode of our database to noarchivelog then open the database, then returned it to archivelog mode then that fixed the problem. But the thing is after 6hours its abnormal behavior goes back again.

It gives proper / desired results. I want to use it on my Form, how can it be done?

I have two varchar variable which has value like this
v_outpunch1:='17:50:00'
and v_Shifttime:='18:00:00'
this both time i am subtracting here and storing in another varchar variable which is like this.
v_EarlyLeaverstimeformat := LPAD((extract(hour from TO_TIMESTAMP (v_ShiftTime,'HH24:mi:ss')) - extract(hour from TO_TIMESTAMP (v_OutPunch1,'HH24:mi:ss'))), 2, '0')||':'|| LPAD((extract(minute from TO_TIMESTAMP (v_ShiftTime,'HH24:mi:ss')) - extract(minute from TO_TIMESTAMP (v_OutPunch1,'HH24:mi:ss'))), 2, '0')||':'|| LPAD((extract(second from TO_TIMESTAMP (v_ShiftTime,'HH24:mi:ss')) - extract(second from TO_TIMESTAMP (v_OutPunch1,'HH24:mi:ss'))), 2, '0');
it's not subtracting value correctly.

I have written a stand alone (Java SE 1.6) JMS client program to consume AQ's messages via Oracle JMS API (aqapi.jar). The queue is a multiple consumer queue, and i just created one subscriber on it. My JMS client program receives messages asynchronously by setting the MessageListener using the setMessageListener method.
Watching the work of the program, I found significant delays in receiving messages that are up to several seconds. When I turned on the diagnostic trace, I found that in the absence of messages listener (AQjmsSimpleScheduler) gradually increases the delay time up to 15 seconds:
Thread-1 [Mon May 06 22:14:23 MSK 2013] AQjmsSimpleScheduler.feedData: Got a non null message, the sleep time is reset to 0
Thread-1 [Mon May 06 22:14:23 MSK 2013] AQjmsListenerWorker.run: sleep 0 millisecond.
Thread-1 [Mon May 06 22:14:23 MSK 2013] AQjmsSimpleScheduler.feedData: Got a null message, the sleep time is doubled to 1000
Thread-1 [Mon May 06 22:14:23 MSK 2013] AQjmsListenerWorker.run: sleep 1000 millisecond.
Thread-1 [Mon May 06 22:14:23 MSK 2013] AQjmsListenerWorker.doSleep: try to wait for 1000 milliseconds
[code]....
Thus, in the worst case, the delay between placing the message in the queue and receiving it by the JMS client is 15 seconds.
Can I control this latency? For example, I would like to explicitly set the levels of the time delays.

I have a multimaster advance replication environment and we have less than 10 transaction per day...I want to propagate data as soon as possible like sync if I setup the schedule push to propagate transaction every 5 seconds as below
BEGIN
DBMS_DEFER_SYS.SCHEDULE_PUSH(
destination => 'orc2',
interval => 'SYSDATE + (5/60*60*24)',
next_date => SYSDATE,
parallelism => 1,
delay_seconds => 10);
END;
/
in other hand ,book(I mean Advance Replication) has written that for simulating continuous push we should setup it as below so it will propagate transaction every 1 minute.
My second question is:I know interval >= 'SYSDATE + (1/144)' means every 10 minutes a job will start and delay_seconds => 1200 means each job remain aware for 20 minutes, but I can't understand the logic?why it can simulate 1 minute propagation?
BEGIN
DBMS_DEFER_SYS.SCHEDULE_PUSH(
destination => 'orc2',
interval => 'SYSDATE + (1/144)',
next_date => SYSDATE,
parallelism => 1,
execution_second >= 1500,
delay_seconds => 1200);
END;
My thrid question is :Which of the above setups is a better solution for my environment?

I'm trying to work out how to take a table like this:
IDDate
12502-Feb-07
12516-Mar-07
12523-May-07
12524-May-07
12525-May-07
33302-Jan-09
33303-Jan-09
33304-Jan-09
33317-Mar-09
And display the data like this:
IDPeriodPeriod StartPeriod End
125102-Feb-0702-Feb-07
125216-Mar-0716-Mar-07
125323-May-0725-May-07
333102-Jan-0904-Jan-09
333217-Mar-0917-Mar-09
As you can see, it's split the entries into date ranges. If there is a 'lone' date, the 'period start' and the 'period end' are the same date.

Version : 4.1.1, I have a tabular form on a DB table. One of the columns is a date field. When the user hits the "add Row" button on the tabular form, I want the Date field to be defaulted to sysdate. Here is what I have tried so far,
1. Created a "hidden" item P1_SYSDATE and populated the default value with sysdate. After this, under the DB tabular report date field, I used default type - Item/application on this page and entered P1_sYSDATE
2. Instead of populating the default value of the P1_SYSDATE hidden item, I created a before regions process and added
:P1_SYSDATE := sysdate
and added P1_SYSDATE to default type of the tabular date field with default type as "ITem/application on this page.
I get the error
ORA-01790: expression must have same datatype as corresponding expression
I tried to_Char(sysdate,'dd-mon-yyyy') and then converting it back to to_date. still no luck.

When I run a query form the the Query Window in Visuial Studios 2012 all the date fields truncated to 'mm/dd/yyyy', but i need the full date returned. I am able to get full date from TO_char(MyDateField, 'yyyy-mm-dd hh24:mi:ss'), but if I do TO_DATE(MyDateField, 'yyyy-mm-dd hh24:mi:ss') it only returns 'mm/dd/yyyy'. I'm sure this is a simple setting in Visual studios but I cant find it to save my life. Is there there a way to have the full date returned by default?

Write a program to declare a date variable and assign it to the current system date. Depending on the day of the month the program should print the following:
If day is 1-10 then print "It is day<day number> of <month name>. It is early in the month".
If day is 11-20 then print "It is day<day number> of <month name>. It is the middle of the month".
If day is 21-31 then print "It is day<day number> of <month name>. It is nearly the end of the month".
For example, if the day is November 30, then print "It is day 30 of November. It is nearly the end of the month".

How can we partition a table based on date if it does not have a date column.
Actually I have to compare two tables on daily basis and fetch few rows from those two tables and enter it to a third table.But both these tables does not have a date column.
I am confused if i need to alter those tables and add date column or if there is some way in which i can compare the data from the two tables for that particular day only and not the whole table data.

I have a small prolem thats best described like this....
a table called TONY with a field named VISITED (date as YYYYMMDD).
We want to populate the field TIMESTAMP (Last visited timestamp, 18 digits) using midnight or 00:00:00 on VISITED value.
Something like:
UPDATE TONY SET TIMESTAMP = �(whatever the formula is involving VISITED).
but i cannot figure out the best way to derive the TIMESTAMP value...
it's a date to epoch conversion, and i can find many examples of Epoch to date, but thats the wrong way around for me i'm afraid!
Oracle 11gR2 by the way...

I need to convert the type of GMT to Local time, during data entry. I have a source table and a target table.
To make the insert get the most value, I have no problems:
insert into destination (SELECT * FROM WHERE source pointnumber = (SELECT MAX (pointnumber) FROM source));
But since times are different between the tables, I want to convert the data obtained to GMT -4:30 Time (Caracas - Venezuela), before inserting it.
I can use a function?
