• How to check the page dirty with default values existing in viewObject?

  Hi all

  I use JDeveloper 11.1.1.4.

  I have two pages in my application. I am browsing for page2 page1.

  Before opening page 2 I created new line page 2 notice of object using method 'Create Insert()' with some default values by using the ViewRowImpl class.

  My problem is that I have a button to return to Page 2. If I click the back button, then check the Application module is dirty or not.

  But it always shows AM is dirty due to I'm setting some default values in ViewRowImpl. If I avoid the default values in ViewRowImpl then AM dirty check works fine.

  My Question is how to check the AM (or) dirty Page with default values in the object view?

  My bean Codes:

  Links DCBindingContainer = (DCBindingContainer) BindingContext.getCurrent () .getCurrentBindingsEntry ();

  DataControl dc = bindings.findDataControl("AppModuleDataControl");

  ApplicationModuleImpl am = ((ApplicationModuleImpl) dc.getDataProvider ());

  If (am.getDBTransaction (.isDirty (()))

  {

  return "Page is dirty."

  }

  My Jspx Codes:

  < af:commandLink id = "cl6" text = '2 '.
  shortDesc = "Add Row in Page2"
  actionListener = "#{bindings." Action CreateInsert.execute}' = 'Edit' >

  Thank you

• Updated several lines with different values

  Hello!
  I have a problem. I need to update more than 1000 lines with different values. How can I do?
  For exsample I have table:
  ID; color, date,
  1 red
  2 green
  3 white
  
  I need to update the date field.
  
  Update table
  Set date = '01.02.03'
  where id = 1
  
  Update table
  Set date = '01.03.03'
  where id = 2
  
  
  Maybe it's how to update multiple rows in a single request?
  
  Sorry for my bad English.
  Thank you!

  Hello

  You can try this

  UPDATE TABLE SET DATE = CASE
                      WHEN ID = 1 THEN TO_DATE('01-02-03','DD-MM-RR')
                      WHEN ID = 2 THEN TO_DATE('01-03-03','DD-MM-RR')
                      END

• 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
  Empty row (i.e. not a single return line) as a line with null values.
  
  For example,.
  
  Select the names of names_mst whose name = "sgasfgs".
  
  Result:
  Names of
  =====
  < null >

  Hello
  If you desire to join external to double, as shown below, you still get at least a line of production

  SELECT  nm.names
  FROM            dual
  LEFT OUTER JOIN names_mst   nm  ON nm.name='sgasfgs';
  

• Updated lines and default values.

  This is my last thread for a while. My final problem with my apex application is related to the update of lines.
  
  I have a tabular presentation to display several rows for a table and want to add a hidden 'updated_by' and 'last_updated' column. I put their default values such as user name and sysdate that work well for new records, but how each line to add these to existing records?
  
  I use 4.02 on 11g.

  Hi Craig,.

  Have you considered using a trigger on the table instead of setting these values from the app? A few advantages are: less logical in the app, especially if these inserts/changes can come from several pages, and once the trigger is implemented it will define values independently from changes and insertions (your form, another form, a non-ApEx client app, etc.).

  CREATE OR REPLACE TRIGGER biu_mytable
     BEFORE INSERT OR UPDATE
     ON mytable    REFERENCING NEW AS new OLD AS old
     FOR EACH ROW
  BEGIN
     :new.updated_by := NVL(v('APP_USER'), USER);
     :new.last_updated := SYSDATE;
  END biu_mytable;
  

  Any insert or update triggers the shutter, define two columns. The NVL call handles the case when a customer non-ApEx brings the insert or update. If APP_USER has a value (ApEx logged-in user), the trigger uses it; Otherwise, it uses the database user ID.

  Hope this helps,
  John

• Spry form validation Date with default value error

  The spry form validation below was created with DW CS6

  I created an HTML form and displayed with PHP to a MySQL database.  One of the lines of form is to enter a date.  This line uses a 'out of the box' sprytextfield data validation without changes to its CSS or JS:

  HTML

  < span id = "sprytextfield1" >

  < label for = "servComDate" > Date beginning? < / label >

  < input type = "text" name = "servComDate" id = "servComDate" >

  < span class = "textfieldRequiredMsg" > a value is required. </span >

  < span class = "textfieldInvalidFormatMsg" > Invalid format. </span >

  </span >

  < script type = "text/javascript" >

  var sprytextfield1 = new Spry.Widget.ValidationTextField ("sprytextfield1", "date", {index: "00/00/0000", format: "mm/dd/yyyy"});

  < /script >

  On request, the form value is captured via PHP and date format is converted to a format of MySQL before entering in the database.

  PHP

  $servComDate = date ("Y-m-d", strtotime($_POST['servComDate']));

  It all works perfectly.

  Now, I created another page with a HTML form to change information.  First, PHP takes the field in the database and converts it to MySQL format to the format used in the sprytextfield above, in which it was created.

  PHP

  $servComDate = strftime ("% m/%d/%Y", strtotime ($row ["servComDate"]));

  Then the HTML form is filled with existing value

  HTML

  < span id = "sprytextfield1" >

  < label for = "servComDate" > if the Service is coming soon, do you know when the service will begin offered? < / label >

  < input type = "text" name = "servComDate" id = "servComDate" value = "<?" PHP echo $servComDate;? > ">"

  < span class = "textfieldRequiredMsg" > a value is required. </span >

  < span class = "textfieldInvalidFormatMsg" > Invalid format. </span >

  </span >

  By filling in the form with existing value appears with the right in the box format, it shows these 'mistakes ':

  value is required. Format invalid.

  As I said above, I have not changed the CSS or JS that is loaded with the Spry textfield, so I don't get that here.

  I'm obviously something wrong with pre-filling a Spry textfield with a default value.

  What is the real need have a default value on a Textfield of Date Validation Spry?

  Thanks in advance!

  Make sure that, in the page change the constructor looks like

  var sprytextfield1 = new Spry.Widget.ValidationTextField ("sprytextfield1", "date", {index: "00/00/0000", format: "mm/dd/yyyy"});

  The following works fine for me

  ">

  A value is required. Format invalid.

• Pulling on the first line with a value of repetition

  Hello
  We use the Oracle 11.1.
  
  We have a table of postal codes.
  
  We have several lines for each zip code because we have different areas that use the same zip code.
  
  We want to reduce the lines of a line by zip code. But they said use they want to keep the fields that differ (neighborhood of the exodus).
  
  Then they said "Just take the first value of each."
  
  This code reduces the postcodes of a line by postal code, but as you can see I replaced the field with the name of the field values.
  

  SELECT distinct  ZIPCODE, CITY, STATE, COUNTY, AREACODE, 'CITYTYPE', CITYALIASABBREVIATION, 'CITYALIASNAME', LATITUDE, LONGITUDE, TIMEZONE, ELEVATION, COUNTYFIPS, DAYLIGHTSAVING, PREFERREDLASTLINEKEY, CLASSIFICATIONCODE,
             MULTICOUNTY, STATEFIPS, 'CITYSTATEKEY', 'CITYALIASCODE', 'PRIMARYRECORD', CITYMIXEDCASE, 'CITYALIASMIXEDCASE', STATEANSI, COUNTYANSI
      FROM   zip_code
  GROUP BY   ZIPCODE, CITY, STATE, COUNTY, AREACODE, CITYTYPE, CITYALIASABBREVIATION, LATITUDE, LONGITUDE, TIMEZONE, ELEVATION, COUNTYFIPS, DAYLIGHTSAVING, PREFERREDLASTLINEKEY, CLASSIFICATIONCODE, MULTICOUNTY, STATEFIPS,
             CITYALIASCODE, PRIMARYRECORD, CITYMIXEDCASE, STATEANSI, COUNTYANSI
  order by zipcode; 

  How should I take either one record per postal code with the first value in these fields or
  
  How should I take the first record for each zip code?
  
  either way works for me.
  
  Thank you

  Hello

  This is called a Query Top - N , and this is a way to do it:

  WITH     got_r_num     AS
  (
       SELECT     z.*
       ,     ROW_NUMBER () OVER ( PARTITION BY  zipcode
                                 ORDER BY          city
                           ,                ...   -- add tie-breakers here
                         )      AS r_num
       FROM    zip_code
  )
  SELECT     *     -- or list all columns except r_num
  FROM     got_r_num
  WHERE     r_num     = 1
  ;
  

  You can simply use MIN or MAX on the columns, as the line with the name of the minimum city do not lowest have area code or the longitude. The above method preserves the first line of each zip code intact, where the 'first': the first in order of aphabetic by the name of the city. If it is not unique, then you may want breakage to the analytical ORDER BY clause.

  If you are deleting rows, you can use this in a NOT IN subquery. If you copy lines to a new table, you can use the query above in an INSERT statement.

  I just see Polywog response:

  You can use the rank or rownumber function...

  If I understand the problem, you don't want to use RANK in this particular case. When there is equality, GRADE will assign 1 to all the contenders. I think the whole point of this thread is that you exactly want a #1 in each zip code, which is what ROW_NUMBER, but not RANK, guarantees.

• 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

  where column1 is null or :p1_filter like '%%'

• Cannot modify the .plist with default values or plistbuddy

  Hello.

  I need to change all my works to print in b & W and duplex printers.

  No problem on my Mac 200 with lpadmin.

  But I can't change the option "reset Presets 'Default settings' Menu after printing" in the box pre-defined for each user.

  If this box is not checked, the predefined color created by the user will be kept again... who live near the top of the entire operation.

  I don't know how to change it in cli.

  In the GUI, I check the box in the print windows and I read the pref file:

  by default, read ~/Library/Preferences/org.cups.PrintingPrefs.plist

  {

  'com.apple.print.preset.defaultToStandardPreset' = 1;

  }

  Not checked the box in the GUI:

  {

  'com.apple.print.preset.defaultToStandardPreset' = 0;

  }

  When I do the same thing with the default command

  write ~/Library/Preferences/org.cups.PrintingPrefs.plist com.apple.print.preset.defaultToStandardPreset 1

  If I read the pref file, the change was made.

  by default, read ~/Library/Preferences/org.cups.PrintingPrefs.plist

  {

  'com.apple.print.preset.defaultToStandardPreset' = 1;

  }

  The box is always disabled

  same thing with the command plistbuddy... same result.

  / usr/libexec/plistbuddy - c "Print: com.apple.print.preset.defaultToStandardPreset ' ~/Library/Preferences/org.cups.PrintingPrefs.plist

  Fake

  / usr/libexec/plistbuddy - c "Set: com.apple.print.preset.defaultToStandardPreset true" ~/Library/Preferences/org.cups.PrintingPrefs.plist

  / usr/libexec/plistbuddy - c "Print: com.apple.print.preset.defaultToStandardPreset ' ~/Library/Preferences/org.cups.PrintingPrefs.plist

  true

  I also tried to clear the cache of preferences "killall cfprefsd".

  I don't know why he doesn't want to apply this setting in cli...

  Thanks for your help.

• Documentation about adding column with the DEFAULT value.

  Hello
  
  http://download.Oracle.com/docs/CD/B19306_01/server.102/b14200/statements_3001.htm#i2198241
  
  < quote >
  If you add a column, then the initial value of each row in the new column is NULL unless you specify the DEFAULT clause. In this case, Oracle database updates each row in the new column with the value specified for the DEFAULT value. This update operation, in turn, triggers AFTER UPDATE triggers defined on the table.
  < quote >
  
  I am not able to understand the emphasis on the part AFTER UPDATE while the column with DEFAULT values addition triggers both BEFORE and AFTER triggers defined on UPDATE.
  
  According to the documents of 11 g
  
  http://download.Oracle.com/docs/CD/B28359_01/server.111/b28286/statements_3001.htm#i2133105
  
  n.m. (u) r only changes with the NON NULL columns, but focus on AFTER UPDATE is still there. No trigger defined on the fire of the update in this case.
  
  This insistence is intended? If not, IMO, it should be changed.
  
  Kind regards

  Hi Sissi. After further discussion, we have added some information about a change in behavior. Here is what says the next version of the doc:

  When you add a column, the initial value of each row in the new column is null.

  * If you specify the DEFAULT clause for a column NOT NULL, then the default value is stored as metadata, but the column itself is not populated with data. However, the following queries that specify the new column are rewritten so that the default value is returned in the result set.

  This optimized behavior differs from earlier versions, when as part of operation ALTER TABLE Oracle database updated every line in the newly created with the default column and then fired defined update triggers on the table. In this release, no trigger is triggered because the default value is stored only in the form of metadata.

  * If you specify the DEFAULT for a nullable column clause, then the default value is added to existing lines under this ALTER TABLE statement, and any update triggers defined on the table are activated. This behavior also means if you change a NOT NULL column with a default value to be nullable.

  Hope that helps to clarify the matter further.

  Kind regards

• default value for date def layout variables

  Hi all

  I need to display from_date and to_date with default values like yesterday and today date in dd-mm-yyyy format.

  is it possible to do without java?

  I tired below:

  (1) registered java. Util.Date in the workflow as DateBean

  (2) variable created in the iterator variable with default values as

  < variable name = "Var2" Type = "java.util.Date" DefaultValue = "#{DateBean}" / > "

  (3) created attribute binding as below:

  < attributeValues IterBinding = 'variables' id = 'This day' >

  < AttrNames >

  < point Value = "Var2" / >

  < / AttrNames >

  < / attributeValues >

  (4) date. MinValue added on fragment like:

  < af:inputDate value = "#{bindings." Label ToDate.inputValue}' = 'to Date '.

  required = "true" shortDesc = "To Date" id = "id1" >

  < af:convertDateTime pattern = "dd-mm-yyyy" / >

  < / af:inputDate >

  He works for today's date, but the format is not as required it gives the date and time

  Also I don't know how to get yesterday's date.

  Please let me know if someone has never tired something like that.

  Thank you

  -Yves

  As far as I KNOW, you can't get yesterdays date without calculation in java.
