• Remove data with null value

  Hello

  I'm using Oracle 11 g. I have a table with an id of 3, node, the value column. Combination of the column id and node, that must be taken account for deletion on the registers.

  Here, I need to delete lines with the NULL value in the value column. If for a combination of id and node with non-null values, then I need to delete rows with a null value for this combination.

  If the combination of id, node is not null value then this records should not delete.

  Below table, I need to remove the second row, for which is a value not zero VOICE CAL '10' is there, so I need to delete the row with null values. (VOICE, CAL, NULL)

  Network, FL, there is no value is non-null then I should NOT delete this line.

  This table is to have 100 s of this association, we can delete data in a single delete query?

  Or how I can delete rows with nulls for this combination.

  Tab1

  VALUE OF THE NŒUD ID

  VOICE CAL 10
  VOICE CAL NULL
  NETWORK NULL FL

  Thank you

  You can do this in a single DELETE statement (it is not a request), using an EXISTS or IN the subquery.  For example:

  REMOVE table_x m

  WHERE the value IS NULL

  AND THERE ARE)

  SELECT 0

  FROM table_x s

  WHERE s.id = m.id

  AND s.node = m.node

  AND s.value IS NOT NULL

  )

  ;

  If you would care to post CREATE TABLE and INSERT instructions for the sample data, and then I could test it.

  Select cell B1 and type (or copy and paste it here) the formula:

  = IF (Len (a1) > 0, LEFT (A1, FIND ("", A1) −1), ' ')

  shortcut for this is:

  B1 = if (Len (a1) > 0, LEFT (A1, FIND ("", A1) −1), ' ')

  C1 = if (Len (a1) > 0, Member SUBSTITUTE (A1, B1 & "", ""), "")

• How to display the line empty as a line with null values

  Hi all
  
  Pls advise me if it is possible to use a single query statement to display

• update of NULL in the column with the values of the adjacent column

  Examples of data

  union all
  select 1 as one, null as two, 2 as three,5 as four, 6 as five, null as six from dual)
  select * from test_data;
  

  This is one of those cases, the case may be where any value of a column can be null

  or two similar columns can be null. If the column is null then I want to update the adjacent column

  average value of the column, if the first column is null so I want to take the next non-null column and update, if the last column is null

  so I want to take prev not zero column and to update.

  In this case would be my expected output

• Add filter slot table form to show the lines with null values

  Hello
  
  I have a tabular presentation where we need to add a filter with two values (selection list) so that if one of the columns in a table (column1) is zero, then I need to display all records where column1 is null.
  
  I was wondering how do I put this in the Source of tabular forms where condition. This filter has only two values,
  
  All the
  NULL for the error
  
  So when the user selects all, then all the records in the table are shown
  If the user selects 'Value Null in error', while the records where Column1 is null will be shown
  
  For example
  

   column1        column2
                         A
                         B
        1               C
        3               D
   

  If the user selects, then
  
  all four files will show up. Else, only the first and the second will be returned.
  
  Thank you

  Hi, Ryan.

  Try a static LOV like this

  STATIC2:;,--- All ---;--- All ---
  

  and a Where clause, like this

• REGEXP_SUBSTR for the list delimited by commas with null values

  Hello
  
  I have a column that stores a list of values comma-delimited. Some of these values in the list may be null. I'm having some trouble trying to extract the values using the REGEXP_SUBSTR function when null values are present. Here are two things I've tried:

  SELECT
     REGEXP_SUBSTR (val, '[^,]*', 1, 1) pos1
    ,REGEXP_SUBSTR (val, '[^,]*', 1, 2) pos2
    ,REGEXP_SUBSTR (val, '[^,]*', 1, 3) pos3
    ,REGEXP_SUBSTR (val, '[^,]*', 1, 4) pos4
    ,REGEXP_SUBSTR (val, '[^,]*', 1, 5) pos5
  FROM (SELECT 'AAA,BBB,,DDD,,FFF' val FROM dual);
  
  POS P POS P P
  --- - --- - -
  AAA   BBB

  SELECT
     REGEXP_SUBSTR (val, '[^,]+', 1, 1) pos1
    ,REGEXP_SUBSTR (val, '[^,]+', 1, 2) pos2
    ,REGEXP_SUBSTR (val, '[^,]+', 1, 3) pos3
    ,REGEXP_SUBSTR (val, '[^,]+', 1, 4) pos4
    ,REGEXP_SUBSTR (val, '[^,]+', 1, 5) pos5
  FROM (SELECT 'AAA,BBB,,DDD,,FFF' val FROM dual);
  
  POS POS POS POS P
  --- --- --- --- -
  AAA BBB DDD FFF

  As you can see that neither calls work correctly. Anyone know how to change the regular expression pattern to handle null values? I tried various other models but could not get anyone to work in all cases.
  
  Thank you

  Hi, Martin,.

  That's what you want:

  SELECT
     RTRIM (REGEXP_SUBSTR (val, '[^,]*,', 1, 1), ',') pos1
    ,RTRIM (REGEXP_SUBSTR (val, '[^,]*,', 1, 2), ',') pos2
    ,RTRIM (REGEXP_SUBSTR (val, '[^,]*,', 1, 3), ',') pos3
    ,RTRIM (REGEXP_SUBSTR (val, '[^,]*,', 1, 4), ',') pos4
    ,RTRIM (REGEXP_SUBSTR (val || ','
                        , '[^,]*,', 1, 5), ',') pos5
  FROM (SELECT 'AAA,BBB,,DDD,,FFF' val FROM dual);
  

  The query above works in Oracle 10 or 11, but in Oracle 11, you can also do it with only REGEXP_SUBSTR, without using RTRIM:

  SELECT
     REGEXP_SUBSTR (val, '([^,]*),|$', 1, 1, NULL, 1) pos1
    ,REGEXP_SUBSTR (val, '([^,]*),|$', 1, 2, NULL, 1) pos2
    ,REGEXP_SUBSTR (val, '([^,]*),|$', 1, 3, NULL, 1) pos3
    ,REGEXP_SUBSTR (val, '([^,]*),|$', 1, 4, NULL, 1) pos4
    ,REGEXP_SUBSTR (val, '([^,]*),|$', 1, 5, NULL, 1) pos5
  FROM (SELECT 'AAA,BBB,,DDD,,FFF' val FROM dual);
  

  The problem with your first request was that he was looking for sub channels of 0 or more non-virgules. There was as a substring. consisting of 3 characters starting at position 1, he returned "AAA", as expected. Then there was an another substring, the 0 characters, starting at position 4, so it returned NULL. Then, there was a substring of 3 characters starting at position 5, so he returned 'BBB '.

  The problem with your 2nd request was that he was looking for 1 or more non-virgules. 'DDD' is the 3rd this substring.

• Update updated the columns with null are excluded from the DB adapter

  Hi all

  My fusion system interacts with DB2 using the DB adapter.

  I have a script that I need to update a flag in the table after completing my bpel workflow. But by updating the value of indicator to "Processsed", there are other columns with a NULL value.

  How to solve this problem. I don't want to do, the other columns should not be alerted.

• How to update columns with the value of other lines in the same table

  Hello
  
  I use Oracle 11.2, I'd use SQL statements to update a column based on values in other rows in the same table. Here are the details:
  
  create table TB_test (number 4 myId, crtTs date, date of MDPU);
  
  insert into tb_test (1, to_date ('20110101', 'YYYYMMDD'), null);
  insert into tb_test (1, to_date ('20110201', 'YYYYMMDD'), null);
  insert into tb_test (1, to_date ('20110301', 'YYYYMMDD'), null);
  insert into tb_test (2, to_date ('20110901', 'YYYYMMDD'), null);
  insert into tb_test (2, to_date ('20110902', 'YYYYMMDD'), null);
  
  After you run the SQL code, I would like to have the following result:

• Value of the link column remove null values

  Hello
  
  I use 4.1.1 and I have a column in a classic report that I have configured to post a link to another page in the application. I use one of the IMGS 'edit' and I put the report to show significant like but when I run my page and the value is null, I get always a hyphen and a link (for example. ("' - that is a link) which redirects me to another page. I know a fast method of sale would be to hardcode the html code in the sql code and I know that you should really put an html tag that is similar between your sql. With this in mind are other suggestions of display and img/a for null values.
  
  
  Thank you very much
  
  Alistair

  You can try css:
  #r_contacts_rowview td [headers = "OFFICE_EMAIL"] a [href = "mailto:-"] {}
  display: none;
  }

  He finds the elements of anchoring with mailto value '-' (my null values) in my office_email column. r_contacts_rowview is a static id for a region.
  Display: none to hide items. This works rather graceful.
  Note that this works in IE7/8 your page should be a doctype ( )

  If you don't want a doctype or whatever it is, you can also try jquery of course
  function remove_hyphen_links() {}
  $("td_[en-tetes_=_'office_email']_{a").each (function ()})
  {if ($(this).)} (Text()=='-')}
  $(this) .remove ();
  };
  });
  };

  If I run this onload of my page, I can see hyphens, shortly before they disappear, I don't like too much. Of course, you must bind it to the "apexafterrefresh" - event in your area, as well as the links are also deleted after a partial page refresh (paging).
