Finding Missing Time Interval in SQL

All
Need help with SQL to find Missing Time Interval.
My query returns data as given below
Data1
Column      StartTime    EndTime
=======   =======   =======
T2               9:00          18:00T3               20:00         23:00
Data2
Column      StartTime    EndTime
=======   =======   ======= T1               15:00          20:00
T3               20:00          07:00
Take above output, I want to find Time Not on my Data in 24 hours from First StartTime on each Data Set.
Example: Data1
First StartTime: 9:00 AM (T2 record)
Add 24 hours, which will be 9:00AM Next day.
Expected Result to get missing time interval for Data1
18:00 - 20:00
23:00 - 9:00 (next day)
For Data2 Expected result
7:00 - 15:00 Next Day
Database version: 11g
Anyone come across to calculate missing time interval? Can I use PL/SQL for this like pipeline function?
Any help/directions/references I highly appreciate.
Thanks in advance.

One way of finding Missing Intervals:
alter session set nls_date_format = 'DD-Mon-YYYY HH24:MI:SS';
with data as
select to_date('28-Jun-2013 09:00', 'DD-Mon-YYYY HH24:MI') start_time, to_date('28-Jun-2013 18:00', 'DD-Mon-YYYY HH24:MI') end_time from dual union all
select to_date('28-Jun-2013 20:00', 'DD-Mon-YYYY HH24:MI') start_time, to_date('28-Jun-2013 23:00', 'DD-Mon-YYYY HH24:MI') end_time from dual
select start_time, end_time,
       case when lead(to_char(start_time, 'HH24'), 1, (select min(to_char(start_time, 'HH24')) from data)) over (order by to_char(start_time, 'HH24')) not between to_char(start_time, 'HH24') and to_char(end_time, 'HH24')
              then to_char(end_time, 'HH24:MI') || ' - ' || lead(to_char(start_time, 'HH24:MI'), 1, (select min(to_char(start_time, 'HH24:MI')) from data)) over (order by to_char(start_time, 'HH24:MI'))
            else
              null
       end period
from data
START_TIME                END_TIME                  PERIOD
28-Jun-2013 09:00:00      28-Jun-2013 18:00:00      18:00 - 20:00
28-Jun-2013 20:00:00      28-Jun-2013 23:00:00      23:00 - 09:00
Time information need not be stored in additional Varchar fields, if you have Date Column. You can use Date fields that store Date and time both.
Another way of approaching this problem is with Connect By Clause or Model Clause. Use the search functionality to find solutions using those methods too. However, in my opinion, this method is the quickest of all.

declare some tmp WA as wa_tmp
loop the data.
adding from date.
wa_tmp = data-from + 1 .
read the next line
read table data index sy-tabix + 1
wa_tmp = to date of next line - 1.
then append wa_tmp to final it.
endloop.

Time interval in SQL query?

Hello ..
I have a database that receives orders as input. The first column is a creationtime column and the second column is a producttype column.
I will make a query that will group by results by the creationtime (to be exact, the months).
Example:
creationtime - productttype - count
11/2007 - prepaid - 100
11/2007 - postpaid - 125
01/2008 - prepaid -75
01/2008 - postpaid - 200
However, while it isn't for certain that every month will be included in the database, I want them all (the months) returned by the query. For example, the month 12/2008 is missing in the database but I want it returned if posible, Since there is only two producttypes availible, for the months they aren't in the database I need to assign a value of 0 for prepaid and postpaid.
In the end, I should get this type of table ...
creationtime - prepaid - postpaid
11/2007 - 100 - 125
12/2007 - 0 - 0
01/2008 - 75 - 200
I am a newbie and let it be no anger if this is a simple query.
Thanks again.

You can use a technique like this to generate all the date ranges you need (here i made up my own min and max dates (boundary conditions)).
ME_XE?with made_up_min_max_dates as
2 (
3     select
4        trunc(add_months(sysdate, - 3), 'MM') as min_date,
5        trunc(add_months(sysdate, + 3), 'MM') as max_date
6     from dual
7 )
8 select add_months(min_date, level - 1)
9 from dual, made_up_min_max_dates
10 connect by level < = months_between(max_date, min_date) + 1
11 /
ADD_MONTHS(MIN_DATE,LEVEL-
01-OCT-2007 12 00:00

01-FEB-2008 12 00:00
01-MAR-2008 12 00:00
01-APR-2008 12 00:00
7 rows selected.
Elapsed: 00:00:00.00You would then have to outer join that to the query you have with the months.

Jitter Analysis Toolkit - Time Interval Error.vi

Hi,
I am having a requirement to find the Time Interval Error. I found that functions under jitter analysis toolkit is capable of finding the TIE(Jitter). I am not sure how to use these functions for my requirement.
My requirement is: I will read the waveform data from a scope and have to process the data and find the Time Interval Error. My only input will be waveform data with jitter from a DUT.
If anybody could help me with the flow how to use the Jitter analysis function for my requirement then it would be of great help. Also, a detailed description about the Tie Interval Error.vi also will be useful.
Thanks,
Mano

If you are just Downloading to a Flat file then why dont you have logic in place for the program to dump the data read into the file to that point depending on any criteria like accounts or customer then clear the internal table and run it in the back ground.
try to use cursor to read the records from the table which will make it a bit more efficient than plain select stement.

How to find out the execution time of a sql inside a function

Hi All,
I am writing one function. There is only one IN parameter. In that parameter, i will pass one SQL select statement. And I want the function to return the exact execution time of that SQL statement.
CREATE OR REPLACE FUNCTION function_name (p_sql IN VARCHAR2)
RETURN NUMBER
IS
exec_time NUMBER;
BEGIN
--Calculate the execution time for the incoming sql statement.
RETURN exec_time;
END function_name;
/

Please note that wrapping query in a "SELECT COUNT(*) FROM (<query>)" doesn't necessarily reflect the execution time of the stand-alone query because the optimizer is smart and might choose a completely different execution plan for that query.
A simple test case shows the potential difference of work performed by the database:

Find start and end execution time of a sql statement?

I am have databases with 10.2.0.3 and 9.2.0.8 on HP UNIX 11i and Windows 200x.
I am not in a position to turn on sql tracing in production environment. Yet, I want to find when a sql statement started executing and when it ended. When I look at v$sql, it has information such FIRST_LOAD_TIME, LAST_LOAD_TIME etc. No where it has information last time statement began execution and when it ended execution.. It shows no of executions, elapsed time etc, but they are cumulative. Is there a way to find individual times (time information each time a sql statement was executed. – its start time, its end time ….)? If I were to write my own program how will I do it?
Along the same line, when an AWR snapshot is shown, does it only include statements executed during that snapshot or it can have statements from the past if they have not been flushed from shared memory. If it only has statements executed in the snapshot period, how does it know when statement began execution?

Hi,
For oracle 10g you can use below query to find start and end time, you can see data for last seven days.
select min(to_char(a.sample_time,'DD-MON-YY HH24:MI:SS')) "Start time", max(to_char(a.sample_time,'DD-MON-YY HH24:MI:SS')) "End Time", b.sql_text
from dba_HIST_ACTIVE_SESS_HISTORY a,DBA_HIST_SQLTEXT b where
a.sql_id=b.sql_id
order by 1;

Finding number of datapoints within time interval

Hello
I have a 2D array, with one column for time/date and one for data measurements. I want to specify a upper and a lower time limit, and then be able to find out how many data points that lies within this time interval. Can anyone help me with this?
Greetings
Kristoffer

Hi,
What I would do is to find the index where the data enters your range and the index where the data leaves your ranger, then just take a subarray out of the original array starting at the first index and going the length to the next index.
The attached vi should be a good template.

Time machine eventually complains about a missing time capsule

In my environment I have the following scenario.
     - Several apple computers are running ML in my network. All of these mashines are configured to use time mashine to do backups to the same set of time capsules.
     - I do use 3 (three) time capsules for backup. One is always stationary, while the 2 others are exchanged in a fixed interval (a couple of weeks). One
        time capsule is always at an external place. The plan is to have a a maximum data loss of a couple of weeks.
Everything is almost running fine. Every hour time mashine is doing backup up to a different disk. The missing time capsule is skipped. But over the sudden
sometimes a time mashine dialog appears, telling me that it could not backup for so many days because the backup disk is missing. The problem is,
there will be no further backup until this dialog is ackknowledged.
I have no idea what situation will trigger this event. I do fear that my unattended server will stop backing up and I do not realize it. Or is this triggered by
some application program which interacts with time mashine?
Any comments are welcome.

You are right, it is good to have diversive backup strategies. I do have others as well - but this is a diffrent story.
I am wondering: am I the only one who uses multiple TC's with one TM?
It is normal bahaviour, that if one backup disk could not be found, TM will use next one. The question is, what
causes TM to complain about a missing disk and stating that there was no backup for say 10 days. The last
successful backup is one hour old. In 99,9% it is working as expected, but once and a while this behavior is showing up.
I am curious to find out if it is a bug in TM or some combination with other programs.

It seems like I just missed the interval for the hard disk replacement program. I purchased in March 2009 a 24 inch Intel iMac . How much does it cost to have apple support at an Apple Store replace a hard drive?

It seems like I just missed the interval for the hard disk replacement program. I purchased in March 2009 a 24 inch Intel iMac . How much does it cost to have apple support at an Apple Store replace a hard drive?

My hard drive continually has the floating beach ball and will take massive time to fulfill a request. And then will not boot up...so then I have to do a restore and rebuild hard drive from a past saved time machine version. Works for a little bit...then the floating beachball comes more and more...until it will not boot up again. So then I restore from a previous time machine saved version....and again it works for a day or so ... until it happens again. Now it's happening faster and faster...so I think my hard drive is dying.

Finding missed sequence numbers and rows from a fact table

Finding missed sequence numbers and rows from a fact table
Hi
I am working on an OLAP date cube with the following schema:
As you can see there is a fact transaction with two dimensions called cardNumber and Sequence. Card dimension contains about three million card numbers.
Sequence dimension contains a sequence number from 0 to 255. Fact transaction contains about 400 million transactions of those cards.
Each transaction has a sequence number in 0 to 255 ranges. If sequence number of transactions of a card reaches to 255 the next transaction would get 0 as a sequence number.
For example if a card has 1000 transactions then sequence numbers are as follows;
Transaction 1 to transaction 256 with sequences from 0 to 255
Transaction 257 to transaction 512 with sequences from 0 to 255
Transaction 513 to transaction 768 with sequences from 0 to 255
Transaction 769 to transaction 1000 with sequences from 0 to 231
The problem is that:
Sometimes there are several missed transactions. For example instead of sequence from 0 to 255, sequences are from 0 to 150 and then from 160 to 255. Here 10 transactions have been missed.
How can I find all missed transactions of all cards with a MDX QUERY?
I really appreciate for helps

Thank you Liao
I need to find missed numbers, In this scenario I want the query to tell the missed numbers are: 151,152,153,154,155,156,157,158,159
Relative transactions are also missed, so I think it is impossible to get them by your MDX query
Suppose this:
date
time
sequence
20140701
23:22:00
149
20140701
23:44:00
150
20140702
8:30:00
160
20140702
9:30:00
161
20140702
11:30:00
162
20140702
11:45:00
163
As you can see the sequence number of the last transaction at the 20140701 is 150
We expecting that the first transaction of the next day should be 151 but it is 160. Those 10 transactions are totally missed and we just need to
find missed sequence numbers

How to change color of a button for specific time interval in jsp

How to change color of a button for specific time interval in jsp.
Please help.
Thanks in advance.

This was driving me crazy, too--and the previous answers did not seem to work. I eventually found that if I click one of the data symbols in the graph in exactly the right spot (see below), it selects only the data symbols and not the line. I can tell this because the little selection dots will be around each data symbol, but no selection dots will be on the line between the data symbols - like the graphic in Yvan's answer. Then and only then will the color symbol in the tool bar show the color of the data symbol, instead of the color of the line. I believe that you then have to first click on the color swatch in the toolbar and then select your color (or choose Show Colors and select from the color tool). Just clicking a color in the crayon box, for example, did not seem to work unless I first clicked on the color swatch in the toolbar, then clicked Show Colors on that dropdown, and +only then+ clicked the crayon or whatever.
_The right spot to click_ seems to be just above the exact center of the data symbol, at least for the diamond shape symbol that I prefer. Sometimes it takes several tries to hit the right spot. If I miss it, the whole line is selected, which is indicated by the little selection dots on the line, between the data symbols. When I click the right spot, those selection dots go away, leaving only the data symbols selected. Then I can change the color, as described above.
I hope this works for you too.

Setting the time interval for LEDs

hello I am new to labview, I am trying to do something simple, but made it a lot more complicated than it needs to be. I need turn on an LED and turn it off, but in random intervals, such as turn it on for 1 second, then turn it off for 2 seconds, then turn it on for 2 seconds, then turn it off for one second, so no real pattern. I need to do this to the LED for a minute, I tried a really convoluted method with a time target and case strictures, but I can only program that to activate in specific intervals, I am not able to set them. Any help will be greatly appreciated. Here is a VI of my convoluted method that didn't work.

You have not tried to implement altenbach's suggestion of autoindexing an array of delays.
The Reshape Array needs to be outside the for loop. You want to reshape the 3x4 2D array into a 12 element 1D array. What you are doing is reshaping a 3 element 1D array into a 12 element 1D array. This results in the last nine elements always = zero.
The Arduino expects an 8-bit unsigned integer. So the data in the arrays should also be U8.
If the index to Replace Array Subset is negative or greater than the maximum index in the 2D array, it does nothing. I am not sure exactly what you are trying to do with the array index manipulations so I did not try to fix it. I added some indicators to show what is happening.
When using autoindexing on a for loop, do not also wire to N.
The Arduino Rseource wires and the error wires should be connected through the loop boundaries with shift registers, not tunnels, particularly not autoindexing tunnels.
I do not have an Arduino, so I used Diagram Disable structures to disable the Arduino VIs for testing without getting errors.
You seem to be allergic to straight wires. Actually the auto wiring tool is probably on and IT is allergic to straight wires. I find it easier to understand a block diagram where the wires do not have excessive bends.

LR5 Find missing photos - search nearby won't work consistently

LR5 seems to work inconsistently when locating missing photos and selecting "find nearby photos".
It has succeeded in finding nearby files but now will only locate one file at a time....a very annoying and time consuming exercise!
Any suggestions please?

Hmm, I'm still not sure about your situation. But if the entire folder was missing (before you started finding individual pics), then it's easy to find the whole folder. You can see if the folder is missing by looking in the Folders pane on the left -- it will have a "?" on it:
Right-click on the folder and select Find Missing Folder.
