• How to validate the columns in tabular form date?

  Hello
  
  
  I have two columns in tabular form date
  
  1.start_date 2.End_date so here I need validate the end_date shouldn't be less than column start_date
  
  so any solution for this?

  Hello

  use a validation of type "Function returning a Boolean" and the following code:

  IF to_date(:YOUR_END_DATE,'YYYY-MM-DD') < to_date(:YOUR_START_DATE,'YYYY-MM-DD') THEN RETURN FALSE;
  ELSE RETURN TRUE;

• A gallery of fluid from MySQL using PHP and various column widths

  I decided to try the new option of fluid page layout in Dreamweaver. I pull information from a (MySQL) database and use php to present.

  To view a gallery, I pull the info and use repetition code and something as horizontal repeat of Tom Muck script to create a gallery. Images should be indicated with other text information (not only a legend). However, the script of HR is a fixed amount of columns - and I want the number of columns to change depending on the width of the browser.

  So it's more than a gallery - pulling images from a database with title = 'x' would be a stylized DIV repeated with multiple fields of texts and styles to the breast.

  For example, a site of car dealer that it must show the image of car, price, year, description etc all fonts of different style so it may just be a legend in the image.

  If the options are:

  A fixed number of columns for each width: Mobile Monitor, 5, 3 shelves, 1. This can be done by having an "IF" statement in the code, if width = x use this version of the horizontal repetition?

  A fluid version which has 6 columns and do you drag the width of the browser, you can see the Gallery less than column width until it reaches 1 for mobile.

  The fluid version would be better.

  Any link to a tutorial or an example would be most appreciated.

  Thank you very much

  The only problem with the use of instead of a table to create columns of the grid is that you need to set a minimum height on the to keep them all at the same depth, a bit like a construction of table cell looks and behaves. If you do not set a minimum height that the grid will look all shredded MORE the very big disadvantage is that the will not clear if another

  has more content in there that's going to happen if you include a 'description' of the car because it will never be the same length unless you are prepeared to edit the text.

  See sample of fluid below: you can simply fill in the of your database and the loop through them

• Take the date of the largest of the 3 Date columns

  Hi all
  
  I have 3 Date/time columns in my table:
  
  DateTime_1,
  DateTime_2,
  DateTime_3
  
  Now select the date maximum or greater of any of these 3 columns. A column can be null. I tried to use a combination of coalesce and features larger to get the maximum date value. When I use a coalesce on 3 columns, it works fine, but when I nested him coalesce in the greater function, that is to say Greatest (Coalesce (...)) it takes a null value. Should I include an nvl on each column?
  
  Any help would be appreciated.
  
  Thank you

  Not difficult at all, unless 4712-01-01 BC is valid a date for you (which is very likely):

  NULLIF(

  I don't think that this is possible.

  what you can do, is that you can fix the scroll bar horizontal to your table, this way that your condition is possible. Please visit the Blog of Mukul to fix scrollbars at the table.

• Fresh fired for FORALL does not not enough values error

  Hello
  
  I am trying to copy data from one table to the other which have a different number of columns. I do the following. But he threw not enough values error.
  
  Table A has more than 10 million records. So I use bulk collect instead of using insert into select from.
  
  TABLE A (has the more columns - 25)
  Number of C1
  number of C2
  VARCHAR2 C3
  C4 varchar2
  ...

  END;
  
  
  When I run this, I get
  PL/SQL: ORA-00947: not enough values
  
  Any suggestions please. Thanks in advance.

  Table A has more than 10 million records. So I use bulk collect instead of using insert into select from.

  That makes sense to me. An INSERT... SELECT will be more effective, easier to manage, easier to write and easier to understand.

  INSERT INTO b( c1, c2, c3, c4, c5, c7, c10 )
    SELECT c1, c2, c3, c4, c5, c7, c10
      FROM a;
  

  will be faster, use fewer resources, much less error-prone and have a more obvious use when a maintenance programmer coming that any PL/SQL block that does the same thing.

  If you insist on the use of PL/SQL, what version of Oracle are you using? You should be able to do something like

  DECLARE
    TYPE b_tbl IS TABLE OF b%rowtype;
    l_array b_tbl;
  
    CURSOR a_cursor
        IS SELECT c1, c2, c3, c4, c5, c7, c10 FROM A;
  BEGIN
    OPEN a_cursor;
    LOOP
      FETCH a_cursor
       BULK COLLECT INTO l_array
      LIMIT 10000;
  
      EXIT WHEN l_array.COUNT = 0;
  
      FORALL i IN l_array.FIRST .. l_array.LAST
        INSERT INTO b
          VALUES l_array(i);
    END LOOP;
    COMMIT;
  END;
  

  At least, that eliminates the infinite loop and the unnecessary dynamic SQL. If you are using older versions of Oracle (it is always useful to display this information at the front), the code may need to be a little more complex.

• Image display: instead of an image, there is a "space" reserved picture icon

  Hi all!
  
  I'm afraid that I need help. As I already mentioned in a thread title, I have problems trying to display an image stored in the database. I've read a zillion threads here about OTN, searched the Internet, but I can't get it to work. Basically, it's what Denes Kubicek provided [url http://htmldb.oracle.com/pls/otn/f?p=31517:64:850093673123067] here
  
  Tools I use are Oracle database 10g XE (10.2.0.1.0) and Application Express (3.2.1.00.10).
  
  There is a table that contains information about some products (such as toner printer cartridges, CD-ROM etc.). This is its description:

  SQL> desc pm_materijal
   Name                          Null?    Type
   ----------------------------- -------- --------------------
   ID                            NOT NULL NUMBER
   IDG                                    NUMBER
   SIFRA                                  VARCHAR2(30)
   SIFRA_KRATKA                           VARCHAR2(30)
   MODEL                                  VARCHAR2(30)
   NAZIV                                  VARCHAR2(255)
   NAPOMENA                               VARCHAR2(255)
   FILE_NAME                              VARCHAR2(200)
   MIME_TYPE                              VARCHAR2(255)
   BLOB_CONTENT                           BLOB

  One of his files looks like this (the other values in the column are less important) (columns are formatted so that they are a single line):

   
  SQL> select id, naziv, file_name, dbms_lob.getlength(blob_content) len
    2  from pm_materijal
    3  where id = 64;
  
          ID NAZIV                FILE_NAME                                    LEN
  ---------- -------------------- ---------------------------------------- -------
          64 CD recordable 1/50

  Now, I would like to attach an image for these CDs.
  
  In my Apex application, I created an article (on page 7) whose name is P7_BROWSE (Display as "Browse file") - it is used to browse directories for files (images, in fact). In order to support the record table updated, I have created a process (process: on present - after calculations and validations).

  if :p7_browse is not null then
     update pm_materijal set
       (mime_type, file_name, blob_content) =
       (select 
          mime_type, name, blob_content
          from wwv_flow_files
          where name = :p7_browse
       )
       where id = :p7_id;
  
     delete from wwv_flow_files
       where name = :p7_browse;
  end if;

  It seems that it works OK, because - once that I select an image (it's a JPG file, its size is 116 x 116) and press the button "Apply Changes" - the result is as follows:

   
  SQL> select id, naziv, file_name, dbms_lob.getlength(blob_content) len
    2  from pm_materijal
    3  where id = 64;
  
          ID NAZIV                FILE_NAME                                    LEN
  ---------- -------------------- ---------------------------------------- -------
          64 CD recordable 1/50   F477411270/cd_50_komada.jpg                 2111

  My next step was to create a stored procedure that will be used to display images:

   
  SQL> create or replace procedure image_display (p_id in number)
    2  as
    3    l_mime        varchar2 (255);
    4    l_length      number;
    5    l_file_name   varchar2 (200);
    6    l_blob        blob;
    7  begin
    8    select mime_type,
    9           blob_content,
   10           file_name,
   11           dbms_lob.getlength (blob_content)
   12      into l_mime,
   13           l_blob,
   14           l_file_name,
   15           l_length
   16      from pm_materijal
   17      where id = p_id;
   18
   19     owa_util.mime_header (nvl (l_mime, 'application/octet'), false);
   20     htp.p ('Content-length: ' || l_length);
   21     owa_util.http_header_close;
   22     wpg_docload.download_file (l_blob);
   23  end image_display;
   24  /
  
  Procedure created.

  As suggested by a few threads of OTN, I did too (although I understand not WHY, because I created the procedure in a pattern that I use in the Apex; there is no other involved users). In any case: I thought that it would not hurt (but it won't do any good either).

  SQL> grant execute on image_display to public;
  
  Grant succeeded.
  
  SQL> create public synonym image_display for radni.image_display;
  
  Synonym created.

  Back at the Express request: I created a region of reports (Type: SQL query). Its source is:

  select 
    id, 
    file_name,
    mime_type,
    dbms_lob.getlength(blob_content) len,
    --
    '<img src="#OWNER#.image_display?p_id='
           || NVL (ID, 0)
           || '" height="'
           || 120
           || '" width="'
           || 120
           || '" />' image
  from pm_materijal
  where id = :P7_ID

  Finally, run the page! Reports region contains one record that shows the information that I have selected in SQL * more (so it seems that the query returns something, and - I would say that it is correct), but - instead of an image - it has an 'invalid (broken) image' icon (you know, a small white rectangle with a red < font color = "red" > x < / police >).
  
  I can't figure out what I did wrong. This work should , but it doesn't. Could someone, please, point me to the right direction?
  
  Kind regards

  Probably token #OWNER #.
  Can you put the html source of the report, or the HTML source of the image?

• How to return the highest value in a column of numbers less than a given number

  I am a beginner using formulas in number.  I have an inventory in a Numbers spreadsheet (v3.6.2).  Inventory numbers are in a column.  I need to view the last number used or the highest number less than a given value.  In my case, it is 9000.

  I can put a cell to return MAX and it's cool, but I need to know the number < 9000, MAX.

  Hi JS.

  SEARCH is your friend here. One of the properties of the LOOKUP function is that it accepts a 'close-match', which is defined as the largest value less than or equal to the search value.

  

  Formulas:

  A2: LOOKUP (8999.9999999, D)

  B2: LOOKUP(9000,D)

  C2: MAX (D)

• Selection columns of results put less caching

  If I read the docs right, I should be able to create a query with X number of columns to fill the cache, so that a subsequent application which includes a direct subset of these columns would hit the cache. This is not what I see.
  
  I have four columns of the fact of the RPD. The three first, sales, cost and units, come directly from the physical layer. The fourth, Profit, is a subtraction of sales less cost.
  
  Here's what I see:
  
  1. connect to answers
  1B. create queries: year, sales, cost-benefit - it fills the cache.
  1 c. Journal of answers
  1 d. Journal of return in responses
  1. create queries: year, sales, cost - this application do NOT against this cache entry.
  
  2. close all cursors (under Administration... Manage Sessions)
  2B. disconnect
  2 c. Purge Cache
  
  3. go to the answers
  3B. create queries: year, sales, cost, units - it fills the cache.
  3 c. Journal of answers
  3D. reconnect to answers
  3rd create query: year, cost of sales - this query hits in the cache entry.
  
  The only difference between the two sequences is that one refers to a calculated column (Profit) and the other is not.
  
  Either incidentally, I tested with profit defined first as a subtraction logical columns and then again as a subtraction of physical columns having the same behaviour both ways.
  
  Can someone please confirm this behavior and suggest a reason why it should happen?

  Very interesting. I guess that the BI server does not seem to find a cache hit on the case of the measure not calculated as it modifies the original query to get the calculated measure. I could see why she would get confused because the resulting query is very different than without the calculated measure. I suppose that, in this case, you can easily fix it by placing a notice on the top of your BI_F_SALES tables to create the computed column of Profit in the physical layer. I wonder if you might try another case. Repeat your 1. case test, but instead of letting fall the calculated column (Profit) drop one of the columns not calculated (sales or cost). I guess that the cache hit should work in that case.

• less is not more: Thunderbird 38 no longer supports addon for additional columns. How is it BETTER than the previous version?

  change the setting of provision adds number of messages, but no total size value was in previous versions. Why even change or delete useful features in updated versions?

  Are you aware that this functionality is now built in? The addon is supposed to be redundant?

  I remember correctly, is that a similar blend of features are available in the new implementation. You may remember what columns it now offers? I don't have Thunderbird with me here now.
