• Deleting duplicate lines

  Hello
  We need help removing duplicate rows from a table please.
  
  We get the following table:
  

  SSD@ermd> desc person_pos_history
   Name                                                                     Null?    Type
   ------------------------------------------------------------------------ -------- ------------------------
  
   PERSON_POSITION_HISTORY_ID                                               NOT NULL NUMBER(10)
   POSITION_TYPE_ID                                                         NOT NULL NUMBER(10)
   PERSON_ID                                                                NOT NULL NUMBER(10)
   EVENT_ID                                                                 NOT NULL NUMBER(10)
   USER_INFO_ID                                                                      NUMBER(10)
   TIMESTAMP                                                                NOT NULL DATE

  We discovered that rare person_id repeated for a particular event (3):
  

  select PERSON_ID, count(*)
  from person_pos_history
  group by PERSON_ID, EVENT_ID
  having event_id=3
       and count(*) > 1
  order by 2
  
   PERSON_ID   COUNT(*)

      214679        495
      219149        522

  If we look at the id of the person 1 "217045", we can see that he repeats 356 times for event id 3.

  356 rows selected.

  It is prudent to assume that the event id per person with the earlier timestamp id is the one who was in charge of 1st, as a result, we want to keep and the rest should be deleted.
  
  You kindly help us with the sql for the removal of duplicates please.

  ... We must maintain a row of data for each unique position_type_id. The query you provided with gratitude deletes lines keep them all not only one line for the id of the person 119129 regardless of which is the position_type_id.

  In fact, the statement that I posted earlier maintains a line for each separate person_id combnination and event_id; This is what means the analytical PARTITION BY clause. That made this assertion would be clearer if you had a different sample of the value. You posted a rather large set of samples, about 35 lines, but each row has the same person_id, and each row has the same event_id. In your real table, you probably have different values in these columns. If so, you should test with data that looks more like your real table, with different values in these columns.

  How can we change the query so that it holds the position_type_id County please before you delete the duplicate rows.

  You can include positiion_type in the analytical PARTITION BY clause. Maybe that's what you want:

  ...     ,     ROW_NUMBER () OVER ( PARTITION BY  person_id
                                 ,                    event_id
                           ,             position_type     -- *****  NEW  *****
                           ORDER BY        tmstmp
                         )         AS r_num
  ...
  

  CREATE TABLE and staements of INSERTION for the sample data and desired outcomes from these data, I'm only guessing.

• Deleting duplicate line

  Hello
  
  I have a delicate situation.
  
  my query is like this:
  

  select count(*), source, ttype, tdate, qty, rate, cost, charge, impstatus, errorcode, proj_code, res_code, role_code, job_id, extl_id, taskid, rate_curr, cost_curr,ext_source_id, chg_code, inp_type
  from transimp
  where ttype = 'X'
  and res_code = 'NLAB'
  and tdate >= '01-MAR-2009'
  group by source, ttype, tdate, qty, rate, cost, charge, impstatus, errorcode, proj_code, res_code, role_code, job_id, extl_id, taskid, rate_curr, cost_curr,ext_source_id, chg_code, inp_type
  having count(*) > 1

  This query returns me 700 records with count (*) = 3
  which means that they are duplicates of records in the table (Please note we have a primary key, but these documents are double according to the needs of the company).
  
  I want to remove these duplicates, i.e. after the deletion if I run the same query again, count (*) must be 1.
  
  any thoughts?
  
  Thanks in advance.

  Dear Caitanya!

  It is a DELETE statement that deletes duplicate rows:

  
  DELETE FROM our_table
  WHERE rowid not in
  (SELECT MIN(rowid)
  FROM our_table
  GROUP BY column1, column2, column3... ;
  

  Here Column1, Column2, Column3 is the key for each record.
  Be sure to replace our_table with the name of the table for which you want to remove duplicate rows. GROUP BY is used on the columns making up the primary key of the table. This script deletes every line in the group after the first row.

  I hope this could be of help to you!

  Yours sincerely

• change the size of the table and remove the duplicate line

  Hello

  I run a program that does a for loop 3 times.  In each loop, the data are collected for x and y points (10 in this example).  How can I output the table with 30 points in a simple 2D array (size 2 x 30)?

  Moreover, from the table, how to delete duplicate rows that contain the same value of x?

  Thank you

• eliminate duplicate lines

  Hello

  I have a report that shows some of the duplicate records and need to eliminate duplicate rows on the report. How to hide the lines duplicated on the presentation of the report so that only 1 row appears on the report instead of having the same line appearing more than once? I use BI Publisher 11.1.1.7. Thank you.

  It is advisable to eliminate duplicate rows to the data model, however, if you do not want to do it on the model please see below

  Whereas you use RTF model

  Change your for each tag to something like this

  If you don't succeed; Thanks for posting your model and an example of xml data

• I use Dreamweaver cc 2014 and after styling css to my fluid page layout grid I lose him resize, delete, duplicate and move up / down ability.

  I use Dreamweaver cc 2014 and after styling css to my fluid page layout grid I lose him resize, delete, duplicate a high displacement / low capacity.

  For this reason I can't build new pages by copying a page to create a new one.

  I have a third style sheet that I use for the styles of navigation and h1 - h6 ect. Tags. and I'm also using a dropdown menu CSS, if one of them can be the problem?

  The menu css that I use has the following script: I spend at the bottom of the html page. Before the closing tag, body

  < script >

  $(function () {})

  $("#nav").tinyNav ();

  });

  < /script >

  I also use the following for an image - I have put it to the top of the fluid

  grid style sheet.

  * {

  box-sizing: border-box; / * Opera/IE 8 + * /.

  -moz-box-sizing: border-box; / * Firefox, another Gecko * /.

  -webkit-box-sizing: border-box; / * Safari/Chrome, another WebKit * /.

  }

  Can you please help.

  My experience is that you should not touch the style sheets that have been created by the system of FGL. Also, there is no need to copy and paste whenever it could disrupt the spoilsports. If you need to apply your own styles and then put them in a second stylesheet, that way if something goes wrong, you can always revert to the original.

• How to delete a line item / of a custom Data Type?

  Hi all
  
  I can't tried to delete a line of a custom data type.
  
  As you will see in the code below I add a line to an array of Type (this is done several times). I then loop through each row in the type of array and pass it the id in a separate function. Once it is I so need to remove this item from the array Type - that's where I think my syntax is wrong because I get an error "ORA-00903: invalid table name.
  
  Clear code

   DELETE FROM TABLE(CAST(l_DeleteList AS TEMP_DOCVERSIONID_TABLE)) WHERE docVersionID = l_DocVersID;

  Complete code

  l_DeleteList.extend;
  l_DeleteList(l_DeleteList.last) := DOCVERSIONID(l_DocVersID);
  
  .......................
  
  select count(*) INTO v_count FROM TABLE(CAST(l_DeleteList AS TEMP_DOCVERSIONID_TABLE));
    -- loop temp table and delete document versions
    WHILE v_count > 0
    LOOP
    BEGIN
      SELECT docVersionID INTO l_DocVersID FROM TABLE(CAST(l_DeleteList AS TEMP_DOCVERSIONID_TABLE)) WHERE ROWNUM = 1;
      DeleteSingleDocumentVersion(l_DocVersID);
      DELETE FROM TABLE(CAST(l_DeleteList AS TEMP_DOCVERSIONID_TABLE)) WHERE docVersionID = l_DocVersID;
      select count(*) INTO v_count FROM l_DeleteList;
    END;
    END LOOP;

  Thanks in advance,

  Trim element removes it from the end of the collection... but you are a loop of the collection from the first to the last clue.

  If you use delete then the item is deleted but index still exists... then array.last and County are not equal...

  You can use something as shown in this example (rather than use a time loop on many items)... after deleting an item to browse a table...

  Copy your document, open the Pages ' 09 and paste the contents of your document into a word processor new document in Pages ' 09.

  Check that the end of the document is delivered on the same page (number) and to the same position on this page as in the original and making small changes at the margin to adjust it if necessary.

  Then go to edit > tools > statistics to see this more comprehensive report:

  

  Note that if you need to present the newspaper article in one format other than a file of Pages, the number of rows may change due to changes in the conversion to the new format of formatting.

  If you don't have a Pages ' 09, you can get a number of lines using tools > line numbers in OpenOffice or LibreOfficeApache. Both are applications open source, free to download and use (even if you might donate help the future evolution of the demand). The links will take you to their respective Web sites.

  Oh... One more thing (as long as Steve jobs used to say sometimes): pages (3), go (menu) Pages > provide pages of comments and make a feature request so that the line count (and line numbering) added the capability of 3 Pages.

  Kind regards
