• How do the time difference between two dates?

  Hi all
  
  I use this query to get the time difference between two dates.
  
  Select to_timestamp ('2012-10-03 12:00 ',' YYYY-MM-DD hh)-to_timestamp ('2012-10-03 11:00 ',' YYYY-MM-DD hh) as double diff;
  
  but do not get the correct result.
  
  Thank you

• Find the minimum distance between two SDO_GEOMETRY in Oracle Spatial?

  

  A circle (SDO_GEOMETRY)
  B - polygon (SDO_GEOMETRY)

  CASE:
  B contains A (or)
  The Interior of B.

  How to find the minimum distance between A and B in Oracle Spatial

  Hello guuid nameless person.

  What is

  my_answer := MDSYS.SDO_GEOM.SDO_DISTANCE(
     my_circle_geometry
    ,MDSYS.SDO_UTIL.POLYGONTOLINE(my_outer_polygon)
    ,my_tolerance
  );
  

  Now, you may need to pay attention to the holes in your polygon, would you the distance and an inner ring if it was closer to you?

  If the measure is only to outer rings, so something like

  my_answer := MDSYS.SDO_GEOM.SDO_DISTANCE(
     my_circle_geometry
    ,MDSYS.SDO_UTIL.POLYGONTOLINE(
        MDSYS.SDO_UTIL.EXTRACT(my_outer_polygon,1,1)
     )
    ,my_tolerance
  );
  

  And then also beware of the multipolygons as the foregoing only measured against the first polygon in the MultiPolygon.  You need to loop through the polygons of tests just the outer ring in this case.

  See you soon,.

• How to measure the time elapsed between two steps?

  Hello

  In my script, I ask the subsequences. How can I measure the time it takes each subsequence?

  Something like:

  Statement: StationGlobals.TimeElapsed = 0

  -> SOMETHING HERE TO START A COUNTER<>

  call sous-suite

  Popup: Str (TimeElapsed)

  Thanks for help

  StationGlobals.Time = Seconds()

  ... / / stuff in time

  StationGlobals.Time = Seconds() - StationGlobals.Time

• Find the intersection/union between two cards

  Hello.
  I'm trying to find out the changes of State between the two cards.
  I have two cards A and B, what I need to do is to find keys in A that exists in key and B in B that does not exist in a..
  If the key exists in both A and B I want to compare the values of these keys.
  What would be the most effective way to apply it.
  My first plan was to make a loop on the keys has to find b and browse the keys b and find in A, but I guess that there is a more efficient algorithm.
  I think also on the use of java.util.Collections to find union-intersection between the keys in the cards, but then I need to do a search in the two
  maps.
  Any suggestions?

  I want to report the change of State of the node in the GUI.
  A state change occurs if there is a new node in the cluster, which means a new entry to the card since the last audit, or if a node
  Let the cluster has remove entry on the map since the last audit, or if the situation or condition for entry/ip has changed since the last audit.

  By your senario above, I don't think that you have two objects on the map, there is a single object and you want to report the change in the GUI, whenever an object is the value added, deleted or by itself is changed (key is the same) to the map.

  Then, I suggest below things:
  (1) override hashcode and equals method. (Because each time the methods put and putAll are called the hash code equal method checks in the bucket for the equal and similar hash code and if its equal, and then change the GUI for the existing map).
  (2) as suggested earlier, substitute methods of deletion. (Whenever an object is deleted, accordingly you can change the GUI).
  (3) as was suggested earlier, override a method put and putAll (whenever a new object is added, so you can change the GUI).

  And to do this, I don't think you have to browse the map.

• What is the time interval between two Oracle certification exams?

  Hello world

  I'm looking forward to associate level certification in SQL and PL/SQL.

  According to a link from the official website of Oracle, I need to spend the next two STAGES to win the Oracle PL/SQL Developer Certified Associate Certification. The two steps are:

  URL of the location where the screenshots below (measures) is as follows:

  https://education.Oracle.com/pls/web_prod-PLQ-dad/db_pages.GetPage?page_id=653 & get_params = P_ID:162 #tabs - 1

  

  

  There are to options available in two stages , so I chose to give the two following tests:

  1 (from step 1) EXAM: 1Z0-061 (database Oracle 12 c: basic SQL)

  REVIEW 2 (step 2): 1Z0-144 (Oracle Database 11 G: program PL/SQL)

  Now my questions are these:

  Question 1: I intend to take the exam 1Z0-061 first (lets say in June), may therefore take the second exam (1Z0-144) at any time after appearing for the first review or is there no specific time frame in which I'm suppose to take the second review?

  
  

  Question 2: will what type of certification I get if I take only one exam (1Z0-061 or 1Z0-144)? I know Oracle's official website said that in order to get "Oracle PL/SQL Developer Certified Associate Certification", I need to pass the two exams; but what happens if I chose to give only a single review at the present time? In the case giving a single review, what type of document of certification will I right to (wave speculation: right to half certification Oracle PL/SQL Developer )?

  Thanking you.

  
  

  Best regards

  Ankit

  Answer 1: He is there no time limit/limit. Finally, I guess Oracle takes his retirement 1Z0-144, but which does not occur for many years.  They have not even removed from the earlier incarnation (1Z0-147).

  Answer 2: Passing a review in itself does not have a certification or credential.  The only "book", you will have is the sheet of test results.

• How to find the time between two channels of entry in the data acquisition card or pci 6036

  Hello

  I read a lot-related posts on the simultaneous measurement of two input voltage of similar channels in map data acquisition. I know that the best material is "simultaneous measurments of the Series DAQ cards" but I only pci data acquisition card 6036 and I try to understand what is the time between the reading of the two channels . This period is always constant? (must it rely on a voltage (amplitude, frequency, waveform..). I send the sine wave (s) to the two channels and read the values of V, if they read the same value, the difference should always be zero but I get-0,002 to 0.002 Volt difference (I must find a way to convert it in time). A screenshot of my VI is attached. I wonder how I can accurately measure the time delay between the channel.

  I am open to any suggestion, my final goal to read exactly two channels at the same time ((ou connaître le délai exact donc je peux correspondre les données correspondantes étant donné le temps de retard))

• How to find the time to what zero crossing point occur using zero crossing vi

  Hello 
  Im trying to find the time to the point of inflection of a Bio-Signal with the 2nd derivative, then detecet the point of zero of the derivative signal
  What I need, is to mark the point of inflection on my Bio-Signal at the point where the derivative signal crosses the zero.
  

  The second has two scales on the graph, one on each side.  The first has only a single scale. I do not change the name of VI, so both have the same name.

• Could not find the Time Capsule for Time Machine backup drive

  My iMac is running El Capitan and Time Machine is unable to find the Time Capsule backup drive.  I blew the backup several times in hopes that it will fix the problem.   The only thing I found which will allow a return to the top is to unplug the Time Capsule and plug it in again.  The work around works only once, then it's back to "can't find the backup disk.

  For anyone a cela or similar questions are you go in your Utilities folder (in your applications folder) and run the utility airport to see what he says about the disks attached. This cannot work for the readers of time capsule Apple rather than third party readers who have been designated as the backup time drives machine.

• Find the time to restore a data file

  RDBMS version: 11.2.0.4

  Platform: Oracle Linux 6.4

  To test our backup RMAN Tape (Netbackup), we have created a table called BACKUPTEST with a single space data file.

  Then, we have removed the data file. Then was restored and recovered with RMAN's data file and tablespace was again online.

  I wanted to show the evidence to my manager that the data file has been restored. But v$ datafile. CREATION_TIME will show the time when the tablespace is imagined. Is there another way, I could find the time when the data file has been restored other than log RMAN.

  Below is an excerpt after the data file has been restored.
