• The search for Clob columns in interactive report

  I use APEX 3.2 with 10g. I have an interactive report with a query that takes several recordings of 'comments' and the concatenates using a function that returns a Clob. In the report, there are several of these comments columns mixed with some small varchar2 columns.
  
  Using the search bar, if I type in a Word and click OK, it does not seek my Clob columns. On the other hand, I can use the drop-down list in the search bar to indicate I want to only search one of these Clob columns, then the research works.
  
  Is there a reason that my filters 'Text line contains' do not include my Clob columns? I have defined, as the "Standard report column" and they all "filter" checked as a permitted operation.
  
  Greg

  I found a work around for this problem. IR reports do not seem to automatically search for CLOB columns as a search ROWTEXT (unless you are specifically targeting this column). So, I wrapped the CLOB column with:

  DBMS_LOB.substr(clob_column_name,4000,1)

  This converts the CLOB Varchar2 column, which made the report «see» IR Of course, this only works if you want to search for the first 4000 bytes, but the data in my CLOB columns are never more than a few sentences long.

• 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

• SEPARATE, only for some columns

  Hi guys!
  I have a table in which I have to get the separate results of the first 5 columns and attach it with the 6th column. I mean it would be something like this:
  
  Select distinct (col1, col2, col3, col4, col5), col6 table...
  
  I can't do the distinct only in some columns (because if I want to that they accordingly I do the separate for each other each other)... How can I do this?

  It would be something like this:
  Select distinct (col1, col2, col3, col4, col5), col6 table...

  no doubt:

  select *
    from (select col1,
                 col2,
                 col3,
                 col4,
                 col5,
                 col6,
                 row_number () over (partition by col1, col2, col3, col4, col5 order by null) rn

• Is it possible to search a single column in a multi column data store?

  Suppose I have create a context index by using a data column for the columns first_name, middle_name, last_name multi store.
  
  So I can search for all the columns in the index using contains().
  
  Is it possible to use contains() for just search one of the columns in a warehouse of multi - for example just last_name column?
  
  In some cases a desire to search for all of the columns, in other cases, only one of the columns.

  Yes, see the doc:
  http://download.Oracle.com/docs/CD/B14117_01/text.101/b10730/cdatadic.htm#i1006391

  If you use the default behavior, so your column data will be separated by XML tags.

  You must then define each of these items, or to use 'auto_section_group '. You can search on them to help

• Reg: Search for nullable columns

  Hi all
  
  I have a DIAGNOSIS table that has a QDESC as a nullable column.
  DIAGCODE and SDESC columns are not nullable.
  
  I wrote a stored procedure to retrieve the records from the table of DIAGNOSIS based on the values of columns specified.
  
  P_ < nom_de_colonne > indicates that the parameter passed to the stored procedure
  
  Correspong SQL statement goes as follows.
  
  SELECT * DIAGNOSTIC
  WHERE
  UPPER (DIAGCODE) AS
  (CASE WHEN LENGTH (p_DIAGCODE) > 0 THEN '%' |) Upper (p_DIAGCODE) | '%' ELSE '%' END)
  
  AND UPPER (SDESC) AS
  (CASE WHEN LENGTH (p_SDESC) > 0 THEN '%' |) Upper (p_SDESC) | '%' ELSE '%' END)
  
  -QDESC is a nullable field; but the following logic doesn't :-(
  AND UPPER (QDESC) AS
  (CASE WHEN LENGTH (p_QDESC) > 0 THEN '%' |) Upper (p_QDESC) | '%' ELSE '%' END)
  
  
  Examples of data in the table is as follows.
  
  DIAGCODE SDESC QDESC
  --------------- ------------ ------------
  123 / / DESC 1 AAA
  123 / / DESC 2
  123 / / DESC 3 BBB
  123 / / DESC 4
  
  
  When I use the query above to search for records with DIAGCODE like 123, I get
  
  DIAGCODE SDESC QDESC
  --------------- ------------ ------------
  123 / / DESC 1 AAA
  123 / / DESC 3 BBB
  
  
  That is to say QDESC with null values are not displayed.
  
  How am I supposed to change the query to get the correct result?
  
  Any help would be much appreciated.
  
  Thank you best regards n,.

  There are several illusions here.

  First of all: SQL has a logic to three values: TRUE, FALSE and NULL. The result of any operator is TRUE or FALSE and that you can only search for NULL values explicitly using IS NULL.
  Second: You need the dynamic SQL statements: immediate execution or dbms_SQL. Your variable is a column name, not a constant, if you need to build a string that contains the required SQL statement and present the use execute sql immediately or dynamics.
  This will reduce scalability.
  Third: < function name > < some constant > = (column) will ensure that any index on < column > is not used.
  Usually, this will result in catastrophic performance.

• To search in multiple columns

  Hello
  
  I have a table of the CITY with the columns ID, NAME, DESCRIPTION and I have another table with the columns ID, FIRST_NAME, LAST_NAME, CITY_ID and me have the CITIZEN Table View that represents the columns CITY.NAME, PERSON. First name per PERSON. LAST_NAME.
  
  The customer is able to enter several words iin an inputText field and then click on the search button. A search query might look like this: Springfield + Simpson.
  
  My query is supposed to do the following scenario. Research in PERSON. First name to Springfield and Simpson, pick up in PERSON. Last_name for Springfield and Simpson, research CITY.NAME of Springfield and Simpson, and research in the CITY. DESCRIPTION of Springfield and Simpson. The query must return all CITIZENS which contain the words from 2 to 4 columns.
  
  I tried to create an index und using the sql - clause, but this did not bring me anywhere.
  
  Anyone have an idea on how to do it?
  
  Thank you
  Tobias

  I tried to create an index und using the sql - clause, but this did not bring me anywhere.

  What have you tried so far in this regard?

  You should probably ike into something like

  var your_string varchar2(1000)
  
  exec :your_string := replace('Springfield + Simpson','+', ' and ')
  
  select *
    from person
   where contains (first_name, :your_string) > 1
      or contains (last_name, :your_string) > 1
  union all
  select *
    from city
   where contains (name, :your_string) > 1
      or contains (description, :your_string) > 1

• What happened to the separate search bar that was in my previous version of firefox 37?

  It seems that the search has been integrated in the position of the url bar

  There is always a search bar! It could, however, have slipped from your main toolbar, whether due to being crowded out by other icons, or due to a glitch.

  You have an infinity icon in your main toolbar (looks like to > >)?

  If you want to restore the default set of icons of the toolbar, which should include the search bar, it has a button for this. If you open the customization to the bottom panel, search for "Restore Defaults". This article has more information on customization: Customize Firefox commands, buttons, and toolbars.

  Now... There are many modules that could affect your toolbars, others by their design and some by chance. Because we do not have information on what you have installed extensions, a quick test to see if an extension might be spoiling the bar would be to test Firefox Safe mode. It is a standard diagnostic tool to disable some advanced features of Firefox and extensions. More info: questions to troubleshoot Firefox in Safe Mode.

  Does not work if Firefox: Hold down the SHIFT key when you start Firefox.

  If Firefox is running: You can restart Firefox in Mode safe mode using either:

  • button "3-bar" menu > "?" button > restart with disabled modules
  • Help menu > restart with disabled modules

  and OK reboot.

  Two scenarios: A small dialog box should appear. Click on 'Start mode safe' (not update).

  Your search bar appear?

• How to get a separate account of several columns

  I've done this before and I'll darn why I don't remember this.
  
  A table with 3 columns with the primary key defined in the column.
  
  Line a, b and c
  NUM.
  1 020 how abc
  2 why 030 def
  3 010 no IGS
  4 how 040 abc
  Yes def 5 050
  6 060 why def
  
  So what I want is a number of unique values to columns b and c as if b and c were in fact a field.
  
  So the result of the query:
  Count = 4 unique lines.
  
  I hope I make some kind of sense. It is a bit much to know if the number of occurrences of each duplicate value, I know not just get the number of unique lines of lines not indexed will be enough. Because the query is supposed to be universal for several digital and alphanumeric data columns and can be extended for several columns, I'm just trying to get a basic skeleton which works for an analysis "on the fly".

  It will be useful.

• Modify the search criteria for my tabular presentation...!

  Hey guyz I m back with a query related to my form of tables that I have developed with your help...
  I submitted my application to management 2 day... whatever it well spent, but they want change me the search criteria according to the needs of thr.
  
  1. they want to understand me a drop box that has all the fields in the table as dispalyed... EMPNO, STC, NAME, NATIONALITY, STATUS,
  and next to the drop box, they want to understand me a field blank as if NATIONALITY select in the drop down box and enter the nationality question in the search box button and press search, I should get all the emp with specific nationality
  
  EX: In the drop-down list select NATIONALITY and in the search box, I type GERMAN,... now, when I click I get all available in business German
  
  
  
  2. we got ratings for all the emp in percentages
  Now, select in the drop POSITION in the box enter (HP: 80 - 90) then I should be able to recover all the EMP working with HP position and ratings between 80-90%
  FOR EX: DROPBOX: Position
  TEXT ELEMENT: HP: 80 - 90
  Click on search, I get all the EMP with assessment between 80-90 and so on
  
  How can I change this... .creating a separate search for each column box would have been easy, but how do I apply this what the management wants me... ???
