  Hello

  Your pr.exitValue () has tried?

  I think you also need a finally block that destroys the sub-process

• 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

• Content of the text - how to insert the return code in the textfield?

  Hello
  I'm working on form textfield that allow the user to insert text and save it in the SQL database as the data type long text. User can retrieve the saved text and display in the web page as an article.
  
  The problem I'm facing right now is the article containing the RETURN/ENTER or new paragraph. When I ask article he become one paragraph, if I understand correctly there is a code that I have to insert when user types returrn/enter button until I have record in the SQL database.
  
  Anyone who knows what I need to add the code and how do I do to auto detect when the user hit the return/enter key as a textfield.
  
  Thank you
  Eric

  Thank you Daverms and Azadi for the entries.

  I chose the Daverms method for the input and stored in the database and the display to aid REReplace() of Azadi.

  Thank you guys.

• 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;
  

• How to get the return parameter in sequence teststand ran by labview labview

  Hello

  Executes a test sequence of labview (essentially running "\Examples\TestStand API\Executing sequences using API\LabVIEW\Execute with no Model.vi process") I need to get a parameter returned in 'Settings', after the sequence has run.

  My problem is that I get the value upon registration of the sequence and not the value after execution.

  How?

  

  Vagn

  Vagn,

  in order to obtain the values of the execution, you need access to execution. The following screenshot shows how to access.

  

  Please note that this VI is lying will be called by TestStand. DO NOT USE THIS VI IN A CUSTOM USER INTERFACE!

• How to set the return on investment

  I installed 'just' mink toolkit in LV2011 to get the digits on LCD display information.

  As a starting point, I opened "Example LCD" and change.

  However, KING seems to be an important concept in the vision.

  KING should be measured from the top-fall position?

  However, can you tell me how I can check KING in the picture.

  Included is the example of the superposition of the KING on the ougghta.

  I wanted to put the part or the entire region as the return on initial investment then attempted to verify if the 'get LCD ROI.vi' works correctly.

  but he could not view the return on initial investment on the image.

  How can I fill the KING descriptor to define a region on the image?

  Image: example of poor quality - 640 * 480 jpg

  labmaster.

  Question *) additional: using a code example, I found return on initial investment must be properly defined to identify the numbers.

  Can you tell me the following...?

  (1) rule to define the ROI on an image for good recognition of numbers. (for example, numbers only area...)

  (2) can I do the code to find the original KING (connected to the well of recognition) automatically?

  Changed the idea of rock.

  Don't try with 7digit LED functions... Can be applied to a very limited image.

• FDMEE 11.1.2.4 - how to load the same record source of 2 different custom in HFM members

  Hi Experts,

  We have the following situation:

  We need download a source document unique member 2 custom end balance as well as two rollforward Member custom movement 2 (additions, for example), the SAME account.

  In our GL, we have separate accounts for the additions, disposals, depreciation, etc.   In HFM, we use custom for these last members.

  I tried the multi-dimensions mappoing member card custom 2 individual based on the story.   It works fine, but when I add another condition by using the same account of source and card balance end Member, he only ended up filling a 2 custom members (according to what has been covered last importing).

  What would be the best way to load a single 2 custom members (same account) source document?

  I wanted to use the accounts of logic since I know that would work, but our financial team do not accept this approach.

  It is even possible to load the same record of 2 different HFM Member?  Even if we loaded the file even a second time in another place, I think that it still would replace what took the first time, instead of loading again to another custom on the same member account.  Even if we loaded to HFM on 'merge '?

  Any ideas at all would be appreciated.

  Thank you
  Mark Smith

  Why your financial team will not accept the approach of the accounts of the logic? He is the obvious solution to your problem. FDM or FDMEE, you can only load on the data at the intersection of a target element. If you want to load the same piece of data at several intersections in the target, then you need to have this piece of data repeated in data sources n then you will need something in the source that could identify how unique each copy so you can map correctly. As noted it is one of the main functions of the accounts of the logic, other approaches are likely to be messy, more prone to error and much harder to verify.

  Thanks Frank.

  where should I call the get_line., in my script, I started after the loop as above

  Immediately after open from finifile is a good place:

  ...

  fINFILE: = UTL_FILE. FOPEN (vINFILE_PATH, vINFILE_NAME, 'R');

  -The first line always is a header, to be ignored

  UTL_FILE. GET_LINE (fINFILE, vINPUT_REC);

  ...

  Or you could do later as immediately before the LOOP.

• How to change the return service for the configuration of pair of Eve Active

  You must configure the return Service to manage failures of network/timeouts. See 'Establishment' will return failure political failure/recovery service here (http://docs.oracle.com/cd/E21901_01/doc/timesten.1122/e21635/design.htm#TTREP342)

  The Return Service clause allows you to set up when the transaction must be validated locally where the replication agent does not receive any acknowledgment of the intelligence officer.

  -DISABLE the RETURN sets the number of timeouts before it stops waiting for the Subscriber to answer.
  -You can set attribute SUSTAINABLE COMMIT to commit the transaction with Commit sustainable is set on the current database, after RETURN of SERVICE is disabled.

  At the application level, you can also control what you want to do if there is a timeout, you can set the LOCAL ACTION of COMMETTRE to VALIDATE or NO ACTION. If you want the agent of rep to commit the transaction locally, it is transparent to the application code. If you set NO ACTION, the application
  may decide whether to re - issue the call validation or roll back the transaction.

  The link to the above documentation has more details.

  Hi all

  doScript() evaluates an expression, so just make sure that your Javascript is an expression.
