• How to get the different records for the date max.

  Hi all

  Here is the sample sql for sample table and data.

  Create table student (dept_id number(10), first_name varchar2(10),last_name varchar2(10),join_date date,years_attended number(10));

insert into student values (1,'Ann','Coleman',to_date('3/7/1917','MM/DD/YYYY'),4);
insert into student values (1,'Ann','Coleman',to_date('3/7/1916','MM/DD/YYYY'),5);
insert into student values (2,'Rock','Star',to_date('1/1/1920','MM/DD/YYYY'),5);
insert into student values (2,'Rock','Star',to_date('1/1/1921','MM/DD/YYYY'),6);
insert into student values (3,'Jack','Smith',to_date('7/1/1900','MM/DD/YYYY'),3);

  insert into student values (3,'Jack','Smith',to_date('7/1/1901','MM/DD/YYYY'),4);

  commit;

  I need to get maximum date records when the name and dep_id corresponds to. I wrote the query below and it becomes the expected result, but I'm not sure it's quite effective.

  SELECT s.dept_id, s.first_name,s.years_attended

  FROM (SELECT dept, MAX (join_date) join_date

  STUDENT GROUP BY dept_id) x

  Student JOIN s ON x.dept_id = s.dept_id AND x.join_date = s.join_date;

  This above query returns records like below, and this is the goal.

  DEPT_ID NAME YEARS_ATTENDED

  1                         Ann                                4

  2                         Rock                              6

  3                         Jack                              4

  Can you please let me know the query SQL I wrote is effective or not? This sample table may have less data, but I'm dealing with millions of records.

  Hello

  Thanks for posting CREATE TABLE and INSERT statement. This really helps.

  Here's a solution. I also added a name that seems logical. In which case you can delete:

  Select dept_id, first_name, last_name

  , max (years_attended) Dungeon years_attended (last dense_rank order by join_date)

  the student

  Group of dept_id, first_name, last_name;

  DEPT_ID FIRST_NAME LAST_NAME YEARS_ATTENDED

• How to get the current record in a block?

  Hello
  
  How can I get the registration of a block, but the current record of the records displayed by this block? (for example if the number of records is 50, but the number of displayed records is 10, I want to get the current_record from the 10, not all 50).
  the: system.current_record returns the current all-time record
  
  Thank you

  You can use a combination of: SYSTEM. CURSOR_RECORD which returns the current record and GET_BLOCK_PROPERTY ('BLOCK', TOP_RECORD), which returns the number of the record that is displayed as the first visible record, your result should be something like

  :SYSTEM.CURSOR_RECORD-GET_BLOCK_PROPERTY('BLOCK', TOP_RECORD)+1;

  Hello

  That's what you asked for in Oracle 10:

  SELECT       a.*
  ,       CASE
             WHEN  action = 'break'
             THEN  LAST_VALUE ( CASE
                                  WHEN  action = 'fix'
                                  THEN  author
                                 END
                                 IGNORE NULLS
                             ) OVER ( PARTITION BY  id
                                             ORDER BY      tmstmp
                                  )
         END        AS lastfixby
  FROM       actionhistory         a
  ORDER BY  id
  ,            tmstmp
  ;
  

  Like all of the built-in functions, LAST_VALUE is documented in the manual of the SQL language:
  http://download.Oracle.com/docs/CD/B19306_01/server.102/b14200/functions073.htm#sthref1508

  ... just in case where it might be useful, one of the queries I've tried myself a left subquery joined that Oracle has no right ("a column may be outside not attached to a subquery').

  Much more, it would help if you posted the request.
  It looks like you were using the old outer join notation (+). You can get the desired results by using an outer join with ANSI rating, but I think it would be more complicated and slower than with a LAST_VALUE.

• How to get the last access to the workflow? (OM, WMS) release 11.5.9

  Hello my friends.

  I am looking for information on how to get the date of the access and the user name who did use some WFs in OM and last WMS.

  If it is through the application or running in the background via SQL for the information is not important to me.

  Could you help me with this?.

  Thank you

  the 'item_type' attribute must match the name of the WF?

  Yes (internal name. For example OEOL).

  The custom of those who will not be affected by the upgrade.

  You must run the query that I provided before to identify if the workflow is used or not.

  For the workflow of order lines, it is intended to be used as you use the order management.

  Kind regards

  Hi Vineet Osho,

  You can browse your object using the loop and you can get the name of the table... as below...

  for each (var obj:Object in myArray)
  {
  for (var str:String in obj)
  {
  If (obj [str] is array)
  {
  var arrayName:String = str;
  }
  }
  }

  Thank you

• How to get the time of the device

  Hello

  I'm developing an application in which I send location of the device in lat, long for every 10 minutes.  I want to send some time also with lat, long. This time must be peripheral situation updates for every 10 minutes.  Can someone tell me how do I do this?

  It is not obvious to your OP exactly what you ask.

  Ask you in a certain way a consistent recording time no matter what time zone are you in?

  Or are you just asking how to get the date and time?

  If it's the last QDateTime is one of the ways to get the date and time...

  http://developer.BlackBerry.com/native/reference/Cascades/QDateTime.html

  If you ask for the first answer more complex, you will probably need to check the time against an external clock (say GMT) and then re-reading use the contact information you have saved to determine what the weather was (including a calculation of DST) at this point in this particular time zone.

  Relying on the phone to change accurately that it is time that you move in time zones will not give accurate results.
