return the empty record only when no results not returned by the main query

• First, select records only when the criteria correspond to?

  Hello guys!
  
  I read about a problem all day without finding a solution.
  
  The problem is the following:
  
  I have a vision, which is based on 2 other views including 1 uses a database link. (Not a problem yet because it works as it should!)
  
  In the result of this point of view, I might record n, that have the same attributes 'STR_GEBIET', 'STR_LRT_SUB' and 'INT_QB_NR '.
  My intention is to limit the query result to one of these records only. If I had 5 records the same 'STR_GEBIET', 'STR_LRT_SUB' and 'INT_QB_NR' the query must return only one of these recordings and discard the others. If there is no duplicate, he should select all records.
  
  I hope I could explain my problem? I would be really grateful for your contribution to this problem because I don't see any appropriately to solve.
  By selecting the rownum does not work with the joined views and so I'm kind of lost.
  
  The select query for my opinion is as follows:
  

  select
  x.CNT_QB_MAIN, 
  y.LNG_QB_SUB,
  x.STR_GEBIET, 
  x.STR_LRT_SUB, 
  x.INT_LRT_ANTEIL, 
  x.STR_BE, 
  x.INT_QB_NR, 
  x.INT_FLAECHE, 
  sum(x.INT_FLAECHE) over (partition by x.INT_QB_NR || x.STR_GEBIET || x.STR_LRT_SUB),
  x.INT_TB_NR,
  y.STR_BEARBEITER,
  y.INT_STATUS,
  y.STR_BEMERKUNG,
  y.INT_BEZUG_VERJUENG,
  y.INT_BEZUG_BESTAND,
  y.INT_BEZUG_TOTHOLZ,

  Hello

  Have you tried rownum, but have you also tried row_number()?

  Something like:

  not tested

  select *
  from ( select x.cnt_qb_main
         ,      y.lng_qb_sub
         ,      x.str_gebiet
         ,      x.str_lrt_sub
         ,      x.int_lrt_anteil
         ,      x.str_be
         ,      x.int_qb_nr
         ,      x.int_flaeche
         ,      sum(x.int_flaeche) over (partition by x.int_qb_nr || x.str_gebiet || x.str_lrt_sub)
         ,      row_number() over (partition by x.int_qb_nr, x.str_gebiet, x.str_lrt_sub order by x.int_qb_nr, x.str_gebiet, x.str_lrt_sub) rn
         ,      x.int_tb_nr
         ,      y.str_bearbeiter
         ,      y.int_status
         ,      y.str_bemerkung
         ,      y.int_bezug_verjueng
         ,      y.int_bezug_bestand
         ,      y.int_bezug_totholz
         ,      y.int_bezug_biotopbaum
         ,      g.cnt_gebiet
         ,      g.str_name
         ,      g.str_beschreibung
         from   vt_tbl_gebiet g
         inner join vt_n2k_lrt_fl x on g.cnt_gebiet = x.str_gebiet
         left outer join vt_tbl_qb y on y.lng_qb_sub = x.cnt_qb_main
       )
  where rn=1
  

  And one more thing: creating views on views is something you should avoid.
  In your case it is perhaps best to use a view that selects the distinct values for x.int_qb_nr, x.str_gebiet and x.str_lrt_sub instead of limit thereafter by using Analytics already... It'll be less overhead.

  Problem with messages sent by post El Capitan:

  not in my folder "sent" as they did.  Can anyone help?

  The mailbox list is divided into categories with such topics on my Mac. When you position the cursor on one of these positions (with the exception of the mailboxes), you should see the Word display / hide it on the right. Click view, if that's what you see.

  In the category of the mailboxes, the mailboxes are arranged in groups, such as Inbox. To the left of each group is a small tip of arrow. If the arrow points to the right, click it so that it points downwards.

  Also note that you may need to scroll the list of mailboxes upwards or downwards to see it all.

• [BUG] Timeline poster frame empty or invisible when it is not empty. (Flash CC 2014)

  Hello! I don't know why flash does, but at a certain point in my timeline a keyframe appears to be when the scene clearly shows a clip. Everything works normally, the clips spread properly and I can double click in and out of the it scene, I can even point to one of the apparently empty frames where the clip exists and it selects the clip on the stage. If it's not hinder my work, but it is a little disconcerting. y at - it anyone who has experienced this bug and found a way to solve it? I think it might have something to do with this flash being excessively long, 18 177 image file. But I'm not sure that this is necessarily the cause.

  I tried to restart flash and my computer.

  I tried to copy and paste the clip somewhere else on the timeline but it always also has invisible, or empty, in the timeline. It does same when I drag the clip on the stage from the library.

  I tried to copy the entire file in a new flash file and the same two clips are still invisible.

  Other clips from the library also refuse to appear in the calendar when you drag from the library onto the stage in the same place on the timeline. Clips placed on the stage, or created prior to this point in the timeline normally appear on the timeline.

  Screenshot:

  

  You can see how the clip is selected, indicated by the blue box on the stage and the frame of the timeline is selected, but the border appears as empty. This is clearly not empty. Any ideas?

  I don't know if it's important but:

  -two clips at the end of the animation are those in question, an image 18 177 file.

  -I am running on an iMac of 2013, OS 10.10.3, Adobe Flash CC 2014 build: 14.2.0.20

  It is not really a bug, it's a limitation, that you get also in other cases, the limit of width for bitmapdata instance.

  kglad solution works for frames up to 32000, and could in theory it takes an another movieclip in the last image of the movieclip inside, give you another 16000 images and so on. But there is another approach that might work for frames up to 256 million.

  I see that in your scenario, you have video clips which last as long as the sound that accompanies it. You could place each of these clips in consecutive images on the main timeline, and on every image, you would also have a sound event audio for this movieclip. Or you could put the audio of this movieclip into the movieclip itself, as its flow.

  In the first frame of the main timeline, you would stop, and action in the last frame of each movieclip, you might have this script:

  MovieClip (parent) .gotoAndStop (MovieClip (parent) .currentFrame + 1);

  When you play this at the playhead stops on frame 1 of the scenario main, then movieclip 1 will play to its effect, its own internal audio stream, either with a scenario main audio event. When it gets to the last image, it will tell the main timeline to go to frame 2, where movieclip 2 would play through his own, and the same script on its last image.

  In this way, you can have 16000 images on main timeline containing 16000 footage, 16000 views each.

• OfficeJet 6700: ADF works only when you scan not copy

  Our officejet 6700 has an irrational problem - will take the ADF and scanning a document using the pc without problem, but if load you something using the function copy on the machine itself, he acknowledges that he is a responsible original, you hit copy and is not feeding the sheet through and copy from scratch!

  Any ideas?

  Thank you

  Hello @edtech,

  Welcome to the Forums of HP Support! I see that you are not able to use the ADF on your HP Officejet 6700 Premium to make Copies, but you can use it to perform a scan.

  I would like you to do a hard reset:

  1. disconnect all cables and cards of memory in the printer. Unplug the power cord, directly from the back of the printer when the printer is still on.

  2. unplug the other end of the power cord.

  3. If there is a power supply on the power cord, disconnect one end and reconnect it.

  4. at the end of 60 seconds, plug it directly into a wall outlet (not a surge protector or battery backup because they can cause the printer to lose over time basic functionality).

  5. connect the power cord to the back of the printer.

  6. the printer should automatically power back upward. If not, turn it on with the power button.

  7. try to make a photocopy (if your printer is a printer all in one) before you connect the cables from the printer.

  8. connect the other cables needed to the printer.

  Are now able to make a copy using the ADF? If you are still unable to make a copy, you will need to contact our technical support at www.hp.com/contacthp/.

• How to use a formula in column in the main query?

  Hi all
  I tried to use a formula columns defined in a query in the State of the query like this:
  where (: cf_ex -: cf_ex2) > = 5
  but when I run the report returned data! Why? and how to use the status of the query?
  
  Note: I'm using Forms 6i

  I gave you the reason:

  Formula columns are not part of the select statement (which runs in the database), but are dealt with in the report.
  So you actually reference the user settings in the query, not formulas columns.

  (Well, I should have said "you are referencing empty connection parameters", but with your experience you could have understood that)
  and the solution:

  Create database for cf_ex and cf_ex2 functions and use them in your application.

• * How to display the group from the main query for the first time in the report?

  Hello
  
  I have developed a group of master / detail in a report
  The master has its extensible framework and the detail of one another framework extensible and put to another page in the page layout.
  The problem is that the master one appears (the same record) in the pages in time equal the number of records in detail that is specific for this master record!
  Example:
  If the master record got three Details then database will show three times (three pages) and then running page number 4 will display the three detail records.
  
  How to make the master data in shown only for once (page number 1 only) and then display the details three records to the next page (page number2) at run time?

  Hello

  the question is, what you've done for this. By default the primary record is displayed only once. Could it be, that the master-fields are inside the extendable frame for more details?

  Try to use the guided navigation and show the report with the single title discovers when returns no results (or) another way is, you can have a no display of results of your choice in the same report.

  Steps guided way-
  (1) create a report with the only title discovers say r1 and r2 is the report itself.
  (2) r2 here itself will act as interim report.
  (3) edit dashboard and shoot two sections in a section pulling other traction r2 and r1.
  (4) now go to section properties and guided naviagtion section with r1 and r2, select report as interim report and show that if ask returns nothing.
  (5) in the same way go to properties of section and guided naviagtion section with report r2 and select report r2 as interim report and see that if ask return lines.

  I hope this helps.

• Subselect query returns "invalid identifier", but the nested query return lines

  I don't think it's a general SQL question.

  Select * from persons where person_id in)

  Select person_id with people whose name = 'Obama' - subquery

  ) and age > 18;

  When I run the subquery, I get:

  ORA-00904: "PERSON_ID": invalid identifier

  00904, 00000 - '% s: invalid identifier '.

  * Cause:

  * Action:

  Error on line: column 5: 8

  This is because the table people do not have the person_id field.

  But when I run the nested together query it returns all the lines in people with the AGE greater than 18.

  How is he succeeds when the subquery is obviously wrong?

  Yes - this is a general SQL question and ask often enough.

  Correlated subqueries depend on the inner query, be able to see and access to the columns of the outer query. Normally see you referenced in the WHERE clause of the subquery and not in the SELECT clause, but the reference is valid in both places. This works because the columns of the tables in the main query are accessible in the subquery. "Person_id" is probably a column in the table 'people '.

  Which can be a cause of problems 'odd' when the column (in your case "person_id") is more of a table.

  Use an alias in the subquery in the subquery and you will find that it will not succeed.

  See these two articles AskTom where he addresses this specific issue

• How to preset the order of the lines in the outer query of a correlated query?

  Hello
  
  I have the following simple query:
  

  select empno,
         ename,
         sal,
         sum(case
               when rn = 1 then sal
               else -sal
             end) over (order by sal, empno) as running_diff
     from (
           select empno,
                  ename,
                  sal,
                  row_number() over (order by sal, empno) as rn
             from emp
            where deptno = 10
           );

  Who calculates a difference running and uses «row_number() over (...)» which is a specific feature of the Oracle to do it. We get the following result (that we will consider correct):
  

       EMPNO ENAME             SAL RUNNING_DIFF
  ---------- ---------- ---------- ------------
        7934 MILLER           1300         1300
        7782 CLARK            2450        -1150
        7839 KING             5000        -6150

  I wanted to arrive at a different solution from the solution, it was not a specific Oracle . I tried the following code:
  
  (EDIT: after further thought, this code is entirely different sense and will never get closer, the result above.) Considers that it is wrong and ignore this attempt.)
  

  select a.empno,
         a.ename,
         a.sal,
         (select case
                   when a.empno = min(b.empno) then sum(b.sal)
                   else sum(-b.sal)
                 end
            from emp b
           where b.empno <= a.empno
             and b.deptno = a.deptno) as running_diff
    from emp a
   where a.deptno = 10;

  but the result is
  

       EMPNO ENAME             SAL RUNNING_DIFF
  ---------- ---------- ---------- ------------
        7782 CLARK            2450         2450
        7839 KING             5000        -7450
        7934 MILLER           1300        -8750

  that is a long way from the initial result. I tried everything I could think to order lines before running difference is calculated, but were unsuccessful.
  
  Is there a way to change this second request-(without using Oracle specific features) - without the help of windowing functions that give the same result as the first query?
  
  Rephrase the question above:
  
  Is it possible, using plain vanilla SQL (which is the aggregate functions and operations such as joins and unions) to create a query that produces the same result as the first?
  
  In addition, it is not for production code. It's just an exercise in manipulation set I would like to see a solution for.
  
  Thank you for your help,
  
  John.

  Hi, John,.

  A way to get a total operating (which is essentially what you want) must make a self-join. Join each line (let's call it the current line, or c) for himself and everything that preceded it (call this the previous line or p), and do a regular lump SUM, like this:

  WITH     got_base_sal     AS
  (
       SELECT       deptno
       ,       2 * MIN (sal)     AS base_sal
       FROM       scott.emp
       GROUP BY  deptno
  )
  SELECT       c.deptno
  ,       c.empno
  ,       c.ename
  ,       c.sal
  ,       b.base_sal - SUM (p.sal)     AS running_diff
  FROM       scott.emp     c
  JOIN       scott.emp     p     ON     c.deptno     = p.deptno
                      AND     (     c.sal     > p.sal
                           OR     (     c.sal     =  p.sal
                                AND     c.empno     >= p.empno
                                )
                           )
  JOIN       got_base_sal     b     ON     c.deptno     = b.deptno
  WHERE       c.deptno     IN (10)
  GROUP BY  c.deptno
  ,       c.empno
  ,       c.ename
  ,       c.sal
  ,       b.base_sal
  ORDER BY  c.deptno
  ,       running_diff     DESC
  ;
  

  Output:

  I said you basically want a total runninng. There are two differences between a cumulative and your needs
  (1) you want to have a total of the negation of what is in the table. That's trivial: use a sign less.
  (2) you want the first point to count as positive rather than negative. It's not so trivial. The above query counts all know as negative, but adds an offset to make it appear as if the first item had been posted as a positive, not negative result.

  You don't say what you want to do in the case of a tie (two or more lines having the same sal). The above query uses empno as a tiebreaker, so all sals are calculated as if they were separate. This is similar to what the analytical functions do when the window comes from the ranks. If you want something similar to windowing by scope, which could actually be simpler.

  The above query calculates a running_diff separate for each deptno, similar to "PARTITION BY deptno" in analytic functions. You happen be interested in a single deptno right now, but you can change the WHERE clause of the main query, or to omit, and the query still works. If you don't want this feature (analagoud for not having any PARTITION BY), it is easy to change the query.

  You can also get these results by using a WITH recursive clause. Which meets the criteria to avoid analytical functions and features specific to Oracle, but not on the use of the only clear and simple SQL features.

• Dynamic display of columns in the pivot query

  I have a table called STUDENT_SCORE. I need to display the avarage score/month for 2 years and the monthly score until today "month.
  
  Then assume that it is April 2009. The report will look like
  
  Roll_id 2007avg 2008avg Jan09-Mar09 Feb 09
  101 80.9 70.9 89.7 90.9 56.8
  102 70.9 23.9 87.2 90.0 76.8
  
  
  I tried a bit, but can't fix the monthly score display dynamically.
  
  
  DDL/DML is as below
  
  
  create the table STUDENT_SCORE

  Hello

  The script below produces what you want (as far as I can tell, without your desired results).

  Student_score_smry subquery Gets the year and monthly averages of student_score.
  It is completely static: it always produces 11 monthly columns (from January to November) and the names of columns hardcoded (m01 through m11).
  For dynamic column names you need, I used SQL * COLUMN more orders.
  To get the variable number of monthly columns you need, SELECT from the main query clause uses a script under (dynamic_month.sql) to only show the correct number (which can be 0).

  The student_score_wk_smry of subquery retrieves the weekly averages of the student_score_wk.
  He, too, is completely static: it always produces 6 weekly columns with names hardcoded (w1 through w6).

  There are four preliminary motions, that write two scripts under:
  Prelimiary C1, C2 and C3 queries write orders of COLUMN for annual, monthly and weekly columns in dynamic_columns.sql
  Preliminary motion M written between 0 and 11 items in SELECT-clause in sub-script dynamic_month.sql

  The main script is:
