• How to create the column of the table for long-form Master detail relationship

  Apex 4.1

  Oracle 11g

  I created a form master detail and see the main table hotel_list and table hotel_mapping as detailed below.

  Hotel_list

  ID HOTEL_NAME

  1 Holiday Inn

  Hotel Hilton 2

  Hotel_mapping

  ID HOTEL_NAME MAPPING_NAME

  1 Inn Holiday Inn Select hotel

  2 holiday hotel Holiday Inn Select

  3 hotel Holiday Inn Holiday Inn Hotel

  4 Hilton Hotel Hilton Hotel chain

  Hotel Hilton 5 HiltonHotel

  Table Hotel_name Hotel_list is a linked table Hotel_mapping

  When I add a line to the Hotel_mapping table for the selected row in the hotel_list table, mapping_name of column is null, therefore impossible to create the relationship between the main table and the secondary table.

  I would like to know, how to create the relationship?

  Thank you very much

  Best regards

  Yong Huang,

  simple step see creating a form detailed master with APEX - Assistant Master retail

  and check how to maintain the relationship between two tables,

  simple return the packaged application «Sample of Masters details»

  and try to understand this concept...

  In your example, use Hotel_list.ID as a foreign key in the table Hotel_mapping

  and maintain the relationship with the column ID...

  and choose the display type of the column Hotel_list.ID in table Hotel_mapping as List(Query Based LOV) select.

  otherwise the best way is to create sample on oracle.apex.com

  I hope this helps...

• Form master / detail apex 5 tries to update the lines of details without apparent change

  A form master / detail of Apex default 5.0 creates buttons back and forward on the main table. When you move between records, the detail region launches a message: update 0 row (s), 0 or the inserted rows.

  Glance in occasional of the user, it will look like a mistake: I, what has changed and why it has not been saved?

  If nothing has changed, why is a MRU statement update being generated?

  How do I remove this behavior? Is this a bug?

  You can see in https://apex.oracle.com/pls/apex/f?p=74308:LOGIN_DESKTOP:113903018138704:, the application of MasterDetail Claim_Charge. Credentials are of assistance/Viewer.

  Thank you!

  Hello

  Create a new hidden element Px_RUN_MRU and the value of

  Source used "Always replace the value that exists in the session state."

  Source of Type ' static assignment (the value corresponds to the source attribute) ' and

  Value of source or phrase "N".

  Then create new PL/SQL process for tabular and use the code

  if :Px_RUN_MRU = 'N' and :APEX$ROW_STATUS IN('C', 'U', 'D') then
    :Px_RUN_MRU := 'Y';
  end if;
  

  Make sure that this process is captured in the form of process MRU.

  Then change tabular MRU to love affection

  (:request like ('SAVE') or :request like 'GET_NEXT%' or :request like 'GET_PREV%')
  and :Px_RUN_MRU = 'Y'

• Form master / detail - constraint integrity

  Hello
  I created a form master / single detail. Master block is based on say Table1 with 2 columns and block detail based on the Table2 with 4 columns.
  When I am creating records using this form, I enter data in the main block and then navigate to detail block and then enter data. When I press save button,
  the shape raises the error message ' ORA-02291: integrity constraint (APPS.» "FK_RECORD_IDENTIFIER) violated - key parent not found."
  When I check the query using help-> Diagnostics-> display database error, the insert statement is insert into table2 values (...
  
  I guess that the form tries to insert data into table2 first. Given that no entry in Table1, where the error. What should be done, so that the form inserts block Master data in table1 first before you try to insert data block of retail.
  
  Concerning
  Suresh

  Suresh,

  In the view of The Navigator object , check the block order under the section of data blocks . The master's block should come first, and then only the detail should come. If his is not like that, and then modify the order of the blocks by dragging the main block at the top of the blocks.

  Kind regards

  Manu.

• Form master-detail recording detail does not with ORA-20001

  Hello
  
  I have a master/detail form, the detail record has a timestamp field that I people using systimestamp via the default, it is a single field of view and everthing records very well. But if I change the format of the timestamp field via the DD-MON-YY HH24 attrubutes column, I get the following error on save
  
  Internal error in the routine mru: ORA-20001: error in MRU: line = 1, ORA-20001: find the invalid timestamp value, please check the timestamp format.
  
  Someone knows what's goin?
  
  Thank you...

  Looks like your display only column is based on the database column.
  If this is the case, you have little control for it in ApplyMRU.
  What you need to do is
  a. keep the TimeStamp column hidden with any mask format
  b. Add the form as a table with the format mask you want to display a column of data not

  In a Word, the DB column is in the proper format as required by the ApplyMRU but you display for users of the truncated version of that.

  See you soon,.

• Form master detail

  Hello
  
  APEX 4.1
  
  I m trying to create a master form / details of easy to use.
  The master is a simple standard form and below on the same page there is a tabular presentation containing the details.
  
  The only thing that I could not do so far is to record a new record from the master at the same time with new details.
  If I create a new record of the master and at the same time create detail records for this master (on the same page), when I submit that the foreign key of the details field is not filled (if I get an ORA-01400: cannot insert NULL into... error < < foreign key column > >).
  
  The processes are:
  1. trial of automatic rank of master record (I've filled in the field "Return Key in Item" with primary key of masters)
  2 ApplyMRU for the detail records.
  
  I tried all sorts of things like fill in the default value for the primary key ETC (master), but still, the field is not filled at the time of submission.
  
  When I first create a master without a detailed edit this master and then add details then it's allright (since the primary key field is filled out at the time).
  
  Any ideas on how to solve this problem?
  
  Kind regards

  Have you used the master form wizard / detail? Or did you build it manually?

  Filled in? Have you tried the PK of the master of fill in the columns of detail? A used code snippet would be useful here.

  Try to write a process with a sequence between the 2 above process that fills the table in detail. Assuming f01 is your column of detail that must be updated with the PK of the master the code will look like

  FOR I IN APEX_APPLICATION.G_F01.COUNT LOOP
      APEX_APPLICATION.G_F01(I) :=  ; -- REPLACE PLACEHOLDER WITH ITEM NAME USING BIND VAR SYNTAX (:)
  END LOOP;

• Get details about the form master / detail

  Hello
  I use forms6i.
  I have a clarification on master form / retail.
  If suppose a form with 2 revenge (block master / details) inside.
  We run the form and enter a few details in the main block, and then in the block of details, and so we try to navigate to the record next to the master.
  If he asks "do you want to save the changes?" before moving to the next main record?
  
  Why I ask, this is where we use the model, and she asked you want to save.
  (Even without a model also I get the same).
  Just to confirm if it is the default customer forms and may be in my forms goods are prepared, so that it can behave this way.

  You can issue a MESSAGE in the on-CLEAR-DETAILS-the trigger, this "will save" data in the database, without actually committing.

  Request Express 4.2.1.00.08

  Concerning

  Something like this should do the job:

  CREATE OR REPLACE TRIGGER order_item_table_tr
     BEFORE INSERT
     ON order_item_table
     FOR EACH ROW
  BEGIN
     IF :NEW.order_id IS NULL
     THEN
        :NEW.order_id := v ('P1_ORDER_ID');
     END IF;
  END order_item_table_tr;
  /
  

  To ensure that the treatment of automatic line (DML) the order table returns the key in question > return to key item > P1_ORDER_ID (or however the primary key of the table order is named)

• ADF query Panel poster not only any value in form master detail, but the field has a value.

  Hi, I use jdeveloper 12.1.3 1.

  1. I request ADF, master form Panel and secondary table.

  2. by default create insert button is enabled in the secondary table. ( button)

  3. no data is demonstrated at the start and it's ok because the main table of the form and the details is under the Panel request af.

  4. even if no data is shown in the form of af, when we get the value of the field (i.e. product) to support bean, field returns a value.

  5. If I am not able to disable the button.

  I tried to use backing bean to disable this key under certain conditions (example: If there is a value for the product on the screen can turn on this button), even if nothing appears on the screen, if we get the value for the field (i.e. product) it returns a value.

  

  Hello

  Tell me if I'm wrong, but you want to disable the button if there is no data in the form of master?

  Try with this property disabled in your button:

  Disabled = ' #{bindings. " Product.inputValue == null} ".

  change 'Product' for the field in the form that will always return a value when there is a line.

  Kind regards

• Ensure that the entry is uppercase form master / detail

  Hi all
  
  I'm playing with APEX version 4.0.2.00.09 and have created a master form / detailed using the built-in Wizard. My database has a constraint which ensures all data entered must be uppercase, but retail section allows the text to be entered in lowercase. In the image below, you'll notice that description has an entry in lowercase, i.e. when it is inserted into the database, it returns that uppercase constraint has been violated. Is it possible to have some javascript (or other tricks) related to this text box to force uppercase data as the user types into it?
  
  I noticed a lot of sites mention adding javascript to 'Attributes of the HTML Form element', but I don't have this section when you change the details of projects.
  
  
  http://imageupload.co.UK/Viewer.php?file=yu7i83h5dpk5cy0npsy0.PNG

  JavaScript: since you are on version 4.0 you have dynamic actions.
  Define a dynamic action
  

  
  
  • Event: change
  
  
  • Selection type: jQuery Selector
  
  
  • jQuery Selector:

    td[headers='DESCRIPTION'] input:visible
    

  
  
  • Condition: no strings attached
  
  
  • 
    
    
    Action: set value
    
    • Fire on loading the Page: No.
    
    
    • Set type: Expression Javascript
    
    
    • Expression of JavaScript:

      $(this.triggeringElement).val().toUpperCase()
      

    
    
    • Remove the Change event: Yes
    
    
    • Items concerned:
      Selection type: trigger Element
    
    
    
    
  
  
  
  This will change the characters all uppercase when the textbox loses focus and the value has changed. (ex tab, clicking somewhere else) If you want that to happen as entry is created, you can use the "Key Release" event, but realize it's behavior embarrassing to put the cursor at the end of the string. No problem when adding, but annoying when a change to an entry (e.g. deleting a Mid-string character set the cursor at the end of the string).

  You can also add validation side Server (or calculation), but here you have to loop through the array of apex_application.g_f # partner in your column that you want to validate. Easier validations are added only in version 4.1 (no calculations though). There is also no "Post calculation calculation" on an element of presentation table as it is on a page element. (that Munky probably refers to?)

• Line selector, box - detailed form Master

  I'm working on form master detail. According to the business rule uses should not remove any line, but users can add lines.
  Therefore, I must hide the buttons remove and check boxes (including master CheckBox). I have set the hide buttons, but I have the challenge on the box.
  To hide the column of the box, I unchecked the box display of line selector in the report attributes. Even if the boxes were gone, I could not add a new line.
  
  Please help me to hide the checkboxes with possibility to add new lines.
  
  Thanks in advance,

  Sam,

  If you do not plan to delete, you can set the status of the Multi line safely delete forever. I did it for you.

• Detailed form Master in Apex - creating main records and details at the same time

  I m trying to create a master form / retail.
  The master is a simple standard form and below on the same page there is a tabular presentation containing the details.
  
  I am facing a problem when you try to save a new record from the master at the same time with new details.
  If I create a new record of the master and at the same time create detail records for this master (on the same page), when I submit that the foreign key of the details field is not filled in. So only one master record gets inserted into the table and record line is not inserted.
  
  When I have everything first create a master without a detail and edit this master and then add details so everything's allright (since the primary key field is filled out at the time).
  
  I just need to confirm that whether in the APEX form master detail, can save master and line record at the same time or is it as master must be registered the 1 and then line must be enterd and saved?
  
  Please let me know, if this functionality can be achieved in the APEX.

  Hello

  There was an error in the process of pl/sql, you referenced f01 (F01. COUNT) in the loop condition and which should have been f03, also you have assigned the wrong field to what should have been P3_DEPARTMENT_ID

  I fixed that. Also, I'm not 100% sure but I think in order to use the table in the column must be of type text or something (and not hidden), but I can't check now because of lack of time.

  A few mistakes during the presentation, but they are still due to constraints on the other fields.

  FOR I IN 1.APEX_APPLICATION. G_F03. COUNTY

  LOOP

  APEX_APPLICATION. G_F03 (I): =: P3_DEPARTMENT_ID;

  END LOOP;
