• Validation of a column in a query SQL-tabular form (updated report)

  Hello
  
  I have a tabular form on a table of type SQL Query (editable report). Users can modify/add lines to the table through the form. I would like to have some sort of validation on each column of the report form. Is there a way I can do it by their SUMMIT. Please note that I did not manually create this form... just use the tools in the APEX. Thank you.

• Tabular form fill a query other tables

  I'm sure this is possible, but we are especially new relations master / detail in the Apex and tabular forms (updated reports).
  
  We are trying to fill a tabular presentation (updated report) with values from a query. The user is simply going to click Yes/No by line and then you insert the lines into a table...
  
  
  I tried following the logic of the creation of a relationship of master / detail and noticed the AddRow Button and the process to add lines in the form of tables. I also noticed that several process of MRUUpdate which to update fire lines existing... I guess I must first add the number of rows that the query that fills the table form pulls inward and then update the lines after that. I tiried do a count and store the value in a text field/Hidden Field Page, then in the AddRows to the MRU I put the domain name with & and. round her. This does not (he cannot add lines and came with an error ora-6502), I then tried to put a: in front of her and who does not have too.
  
  
  Any suggestions on how to proceed.
  
  Thank you in advance,
  -Brian

  Hello

  OK - now you have to decide if you want to allow users to update other values or not. If you don't want to do them this, you can use APEX_ITEM. HIDDEN (3, COLUMNNAME) | COLUMNNAME COLUMNNAME - it concatenates an item hidden in front of the real version of Standard report of the element (substituting 3 and COLUMNNAME values you need). The HIDDEN element will be presented on the page, but the user cannot see it or change it.

• How to add a new line at the top of manual tabular form

  I have a manual tabular form. I am trying to add a line at the top of the form, instead of the new line of being displayed at the bottom. any ideas are appreciated.
  
  Thank you
  Surya

  If you did a manual tabular presentation using a select statement as follows:
  Choose option...

  
  Union of all the
  Select... of double

  Try to simply reverse the two select:
  Select... of double
  Union of all the
  Choose option...

  I did this in an application, and it works.
  (I've never tried with sorting...)

• How to refer to the primary key column of newly inserted rows of tabular form

  Hello

  I use APEX 4.2.0.00.27 with Oracle DB 11.2.0.3.0.

  I work with a tabular presentation wizard-created for insert and update a table using the integrated SRM process (sequence 10).  I'm trying to use a process of anonymous block of PL/SQL (sequence 30) to make another manipulation of table after the records were inserted or updated.  The manual process is associated with my tabular form and I use the variables of name of column binding in my program block.

  My (rsn_test) table has 3 columns: test_id (number), test_nbr (number), test_id2 (number).  Test_id column is identified as the primary key and the type of the source already exists a sequence rsn_test_seq.  Column test_id2 gets its default value 0 to a hidden page element.

  I would use my manual process for updating the value of the test_id2 column.  If it's 0 then I want to put the value of the column test_id.  If it is any other value, then it must remain at this value.  My logic works very well for an existing line, but I'm running into a problem with the newly added lines.  The new lines get inserted, but the test_id2 column remains the default value 0.  I can tell the debugger that the SRM process is triggered first and inserts the line, then my manual dealing with fires.  The problem seems to be that the connection variable: TEST_ID for the primary key column remains NULL after insertion.  I don't know how to get the value of the column test_id of my newly created line to use in my PL/SQL block to my update.

  Process of PL/SQL:

  DECLARE
  BEGIN
     :P7_SHOW := NULL;
     :P7_SHOW := NVL(:TEST_ID2,555) || ' and ' || NVL(:TEST_ID,787) || ' and ' || NVL(:TEST_NBR,9999);
     IF :TEST_ID2 = 0 AND :TEST_ID IS NOT NULL THEN
        UPDATE rsn_test
           SET test_id2 = :TEST_ID
         WHERE test_id = :TEST_ID;
     ELSE
        :TEST_ID2 := :TEST_ID2;
     END IF;
  END;

  Any suggestions?

  I have run tests on

  https://apex.Oracle.com/pls/apex/f?p=83488:1 demo/demo

  to see your problem.

  I have 2 solution for your problem.
  I add trial NOT tabular just usual block of PL/SQL

  	BEGIN
  	I'm IN (SELECT TEST_ID FROM RSN_TEST WHERE TEST_ID2 = 0)
  	LOOP
  	UPDATE RSN_TEST
  	SET test_id2 = TEST_ID
  	WHERE test_id = i.TEST_ID;
  	END LOOP;
  	END;

  and works very well, you can see in the sample.

  The other solution is to show new generated TEST_ID

  Adding a sequence as a default value for a column in a table field

  And to execute your procedure.

  I get how is with the good luck of time.

  When I press the ADD button, a new line must be added to the shape of the table and the data should be saved to the collection. , But currently, the page is being submitted to the database table when adding new lines in the form of tables. The data should only be saved in the database when the user clicks on the APPLY CHANGES button

  I searched the Forum about this issue and have found many discussions which suggested to use JavaScript to add new lines. As I have no knowledge of JavaScript, these solutions have been strange for me.

  Please help me solve this problem.

  Thanks in advance.

  Hi Christophe,

  Follow the changes mentioned below

  1. remove this your Collections initialize

  IF :REQUEST = 'ADD'
  THEN
    APEX_COLLECTION.ADD_MEMBER(p_collection_name => l_collection_name);
  END IF;  
  

  2 condition your collection process initialize

  Modify your process-> conditions-> PLSQL Expressions->: REQUEST IS NULL

  3. create a process more onload I say Add new line to the collection

  DECLARE
      l_collection_name APEX_COLLECTIONS.COLLECTION_NAME%TYPE;
     BEGIN
        l_collection_name := 'EMAILDETAILS';
       IF apex_collection.collection_exists(l_collection_name)
        THEN
            APEX_COLLECTION.ADD_MEMBER(p_collection_name => l_collection_name);
            END IF;
     END;
  

  4 condition your Add new line to the collection

  Modify your process-> conditions-> request = Expression1-> ADD (this should be request ADD button)

  5. change your button-> Action addition-> redirect to this application page :-> page no (same page)->-> ADD APPLICATION

  6. check your through the process conditional Page collection

  Modify your process-> conditions-> PLSQL Expressions->: ASK IN ('ADD', 'APPLY_CHANGES', 'DELETE')

  7. check your subject to the process of Collection to Table under condition

  Modify your process-> conditions-> PLSQL Expressions->: ASK IN ('APPLY_CHANGES')

  8. for the whole process to remove the conditions when the button is pressed.

  If the problems persists, create a sample on apex.oracle.com and share the connection information with the name of workspace.

  Hope this helps you,

  Kind regards

• line tabular form selector ignores the Tab key, how?

  Hello world

  We have Oracle 11.2 and Apex 4.2.6.

  Tabular form a selector of line, trying to prevent cleat key home, for item in normal form, I would use just something like tabindex =-1, but I don't know how I can add this tab index for the line selector, whose property is 'Download' BLOB. If I inspect element, it is a checkbox:

  < input type = "checkbox" name = "f01" value = "1" class = 'row selector' id = 'f01_0001' entered AutoComplete = "off" >

  How can I add tabindex = "-1" inside this entry line selector type?

  Any suggestions are greatly appreciated.

  $(':checkbox').attr ("tabindex", - 1).

  However, it would be preferable to add a static region id to your region and your prefix selector

  $('#p1_my_region_:checkbox').attr ("tabindex", - 1).

  Hi all
  
  I have the small demo application created on demand 4.1.0.00.23 Express. None of the pages has been created as a table. I want to customize with columns to this page. When I click on edit this page and go to the regions - report, I see a field titled "width of the column. Unfortunately, it seems that everything I put in here is ignored. The width of the column remains constant, regardless of if I put 2 or 200 as column width. How can I customize with columns in tabular form?
  
  Thank you for your time.

  Blue,

  Thanks for your suggestion. This page has tabluar shape, and I do not see here of "the column definition. The content area is "Report" and when I click it, I see: "Alias"; 'Link '; 'Change '. 'Title', 'Coumn Width","The column alignment", etc.
  I tried to 20px in the "column width" and I got an "Invalid number" error when I ran this page. But if I put 2 or 200 - column is always in the same width.

  Hi Daniel,.

  On the page you describe with the Alias, the link, position etc. beside the column in question, there should be a link change (type of pencil icon), to get the column attributes for that particular item, you need to click on this icon. On the resulting page there is (on APEX 3.1 there is) a column formatting section of the column, you will see the scope of the CSS style there.

• APEX_ITEM. DATE_POPUP2 in case of manual tabular forms

  Hi all
  
  I'm unable to view the based on jQuery popup calendar in my manuals tabular forms by using the APEX_ITEM. Function DATE_POPUP2. It displays the text of an item but without the calendar button. What I need to change the attributes of the column and set the option ' display as ' on 'Date Picker?'
  
  Request Express 4.0.2. Here is my report query:
  

  SELECT
     cust_first_name,
     cust_last_name,
     apex_item.hidden(1,customer_id,NULL,'f01_'|| '#ROWNUM#')
     || 
     apex_item.date_popup2(
        2,
        SYSDATE,
        'MM/DD/YYYY',
        12,
        12,
        NULL,
        'f02_' || '#ROWNUM#'
     ) dob
  FROM demo_customers

  Please let me know what the problem with my query above.
  
  Thank you!

  Hello

  Try

  SELECT
     cust_first_name,
     cust_last_name,
     apex_item.hidden(1,customer_id,NULL,'f01_'|| ROWNUM)
     ||
     apex_item.date_popup2(
        2,
        SYSDATE,
        'MM/DD/YYYY',
        12,
        12,
        NULL,
        'f02_' || ROWNUM
     ) dob
  FROM demo_customers
  

  I think the problem is that you can't use substitution #ROWNUM # in the report query.
  Your code has generated the same attribute of id for all text fields (id = "" f02_ #ROWNUM # ' ").
  ID attribute must be unique within the HTML document.

• Default values &amp; javascript in tabular form manual

  Hello!
  I have a table that shows a new line in the upper part of the report... my sql statement is in the form of:

    SELECT 
    NULL EMPNO, 
    NULL ENAME, 
    NULL MGR, 
    NULL SAL, 
    NULL COMM, 
    0 SORTITEM, 
    'N' STATUS, 
    '' MD5_VALUE 
  FROM 
    DUAL
  UNION ALL
  SELECT...etc

  I used to have default values defined in the report attributes but those lost when I started using the approach above.
  How to reference the value of an element on the page, a default value for the line empty? For example, if the element: P60_EMPNO contains the employee ID for work, I want the EMPNO field in the empty line is pre populated with this value.
  
  Also, I used to have a javascript function which ran "onkeypress" for a field in the new row, but now I don't know how to implement with the new tabular form.
  
  Thank you!

  Hi Tammy!

  You can replace all NULL values in the SQL statement by your default values. The only condition would be that you should have at least one field that is NULL so that the code in the process knows that the user has not completed registration. In my example, I check:

  IF vSTATUS = 'N' AND vENAME IS NOT NULL THEN
  

  Yes, as long as the status is ' only and the user has not completed the ENAME field, the record will not be created - if, however, I put a default to ENAME, IF this test would be satisfied and, therefore, a new record would be created each time the page has been sent.

  What does javascript code? The APEX_ITEM. Text() function allows the inclusion of additional attributes for the INPUT tag that will be generated. See: http://download.oracle.com/docs/cd/E17556_01/doc/apirefs.40/e15519/apex_item.htm#CHDCDHJI

  In my example, I have:

  APEX_ITEM.TEXT(5, SAL, 7, 7, 'style="text-align:right;"') "Salary"
  

  Which adds the attribute "style" to the issue of the STARTING salary. You could do something like that to add in "onkeypress =" javascript:yourfunction (...); » "
