• How to set the value of a column in a table according to another column?

  Hello world!
  
  I use Apex 4.1.
  My question is how can I set the value of a column in a table according to another column?
  I have a table and when I insert the value in the column content, I want to change this value in the note column with the note, which is generated with pl/sql function (function of string returned if the typed value is in the range).
  
  I tried to use javascript as

   $('input[name=f02]').live('change', function(){
  if($(this).val()!='1'){
  $('input[name=f03]').val("test")}
  }); 

  for the development of the column note to test if the value typed in the content of the column is not 1, but this code assigns the value to all the lines and I need to set only the specified line.
  
  Can someone give me a hint in any way to do this if possible?
  
  Kind regards

  You will need create a process on your page type PLSQL and develop this process "we demand" of the page. In this process, you can run the PLSQL you need. That is to say to retrieve the note value as described in your PC:

  and when I insert the value in the column content, I want to change this value in the note column with the note, which is generated with pl/sql function (function of string returned if the typed value is in the range).

  In this process, you must provide a return value of the call, and you can do this by using htp.p. Example:

  DECLARE
     --putting x01 in a var to simplify
     l_test_var VARCHAR2(200) := apex_application.g_x01;
     l_return VARCHAR2(200);
  BEGIN
     -- a simplistic test
     IF LENGTH(l_test_var) BETWEEN 10 AND 20 THEN
        l_return := 'String is between 10 and 20';
     END IF;
  
     --this will write l_return to the buffer, and the ajax callback will receive this
     htp.p(l_return);
  END;
  

  And the code that I wrote above, which is javascript, would need to go where your current code is that binds to the onchange event. The result should be that, when a change is made to this element, an ajax request is made on the server. When the call is finished, it will be the value returned in the item you want.

• How to set current row in the table after use the button tab on inputText

  Hi all
  My first post.., I am beginner in ADF and I'll try to explain my problem.
  
  For now we use ADF 11 g (11.1.1.4), in a jsff page I have a table with a column of inputText.
  On the the inputText valueChangeListener, I invoke a method in a bean viewScope that call an EJB method, make some services to the EJB on the modified line. After that, I update the VO and the table (because other values in the row have been changed) and reset the focus on the inputText even modified by the user with javaScript, because the focus was lost after updating.
  So far, everything works fine.
  
  When I use the arrow keys to change the selected line in the table, this is excellent work (focus is always in the inputText next or previous), but if the user tries the key tab allows you to change the current line, the inputText on the line that has the focus, but the current row in the table is not changed (I think that is normal).
  
  My question: How can I change the current line after the tab key in this case?
  
  I don't know if it is really clear, not easy to explain, do not hesitate to ask for more details.
  Thanks in advance.

  Hello

  My question: How can I change the current line after the tab key in this case?

  Use a client event to listen to the keyboard entry and intercept the tab. Use af:serverListener to call the server to set the rowKey on the table and deliver a PPR for the table to repaint

  NOW I WANT TO UPDATE T_30 THAT LOOKS AT BELOW:
  
  By top T_30 initially AmendNo pass is null in T_30. Now I want to update
  column based on a minimum value of AMENDNO in the column T_20
  best way I can explain is:
  
  In the table T_20
  For CONTROL 101-> there are two numbers with 1000 but with different Amendno like 1, 2 in.
  and
  In the T_30 Table for CONTROL 101-> there are two IN. with 1000 but currently null. REQUIREMENT IS NOW
  THE TWO DOCUMENTS SHOULD BE UPDATED WITH MIN (AMENDNO) FOR THIS CONTROL T_20. IN THIS CASE FOR THIS CONTROL
  101 MIN (AMENDNO) IS '1' (1, 2)
  
  SO 101 RECORDS (BOTH) OF NOW T_30 SHOULD BE UPDATED WITH '1' AS AMENDNO
  
  Once again 101 now have one another IN '1001' with two different 0.1 IN. now T_30 AmendNo should be updated with min (0.1) which is
  '0'
  
  production is expected to be lower after update:
  

  SQL> SELECT * FROM T_30;

• Select cursor for update: multiple columns of different tables

  Hello
  
  I have two tables test1 and test2. I want to udpate the column (DEPT_DSCR) from the TEST1 and TEST2 using select for update and current tables of the... with the cursor.
  
  I have a code drafted as follows:
  DECLARE
  v_mydept1 TEST1. TYPE % DEPT_CD;
  v_mydept2 TEST2. TYPE % DEPT_CD;
  CURSOR C1 IS SELECT TEST1. DEPT_CD, TEST2. DEPT_CD OF TEST1, TEST2 WHERE TEST1. DEPT_CD = TEST2. DEPT_CD AND TEST1. DEPT_CD IS 'AA' FOR THE UPDATE OF TEST1. DEPT_DSCR, TEST2. DEPT_DSCR;
  BEGIN
  OPEN C1;
  LOOP
  FETCH C1 INTO v_mydept1, v_mydept2;
  WHEN EXIT C1% NOTFOUND;
  UPDATE TEST1 SET DEPT_DSCR IS "PLSQL1" WHERE CURRENT OF C1;.
  SETTING A DAY TEST2 SET DEPT_DSCR = 'PLSQL2' WHERE CURRENT OF C1.
  END LOOP;
  COMMIT;
  END;
  
  The code above when it is run, declares that it runs successfully. But it does not update the columns you want [DEPT_DSCR].
  
  It works only when we want to update one or more columns of the same table... i. e by providing these columns after ' to UPDATE THE.
  I don't know what exactly is the problem when you want to update several columns of different tables.
  
  Can someone help me on this?

• RollbackToSP will be working if the column in the table has been abandoned?

  Hi all
  
  I would really appreciate an opinion on these two scenarios in OWM.
  
  Scenario one
  
  Steps to follow:
  
  
  
  Savepoint1, created may 20
  DIAL THE DBMS_WM. CreateSavepoint ('LIVE', 'RRR_Test');
  
  
  May 21 change us a table with version:
  
  
  DBMS_WM EXEC. BEGINDDL ('users');
  
  
  
  -remove unused column
  
  ALTER table drop column field users_LTS;
  
  
  
  EXEC DBMS_WM.COMMITDDL ('users');
  
  
  
  3 roll back at the point of backup created on 20 may
  DIAL THE DBMS_WM. RollbackToSP ('LIVE ',' RRR_Test);
  
  
  
  
  
  End of the scenario
  
  
  
  Question: Will the OWM correctly changes rollback made to the schema of the table USERS?
  
  
  
  
  
  
  
  
  
  Second scenario
  
  
  
  
  
  1 Savepoint1 created may 20
  DIAL THE DBMS_WM. CreateSavepoint ('LIVE', 'RRR_Test');
  
  
  
  May 21 change us a table with version:
  
  
  DBMS_WM EXEC. BEGINDDL ('users');
  
  
  
  -remove unused column
  
  ALTER table drop column field users_LTS;
  
  
  
  EXEC DBMS_WM.COMMITDDL ('users');
  
  
  
  3 roll back at the point of backup created on 20 may
  (1) add the domain of the column to the schema
  
  (2) rollback
  DIAL THE DBMS_WM. RollbackToSP ('LIVE ',' RRR_Test);
  
  
  
  End of the scenario
  
  
  
  Question: given that the pattern is exactly the same as it was originally, this will work?
  
  
  Your ideas are welcome.
  
  Thank you

  Hi Serge,

  When you add the column to the table, it will be added to all versions/workspaces for this table. All of the current versions, as well as all the historical lines, will contain this new column with a null value or the default value.

  None of DBMS_WM restore procedures will be affected by the DDL changes, or a restore will return all DDL changes made since the backup was created. A backup point cannot become invalid. The restoration works on the level of the line, based on the columns of the primary key (which is not editable by the DOF). So the resulting table will have the same lines as he did at the time that the backup point has been created, adjusted for any changes in the column that has been done on the non-primary key columns.

  Kind regards

• How to remove columns from the table on the master 1-0?

  I have an array of 96 columns with strings. I also have the array of int 96-elemets (mask) with 1 and 0.

  What I want to do is to is to remove (or hide - but I read that it is not possible) all the columns with index corresponding to 0 in the mask table.

  example:

  columns in the table

  1 2 3 4 5

  mask

  0 1 0 0 1

  I want to remove the columns 1, 3 and 4 and leave only 2 and 5 in my table.

  How can I do?

  If I create loop for with i as the index of the column, when I do DeleteTableColumns() columns number decreases, and I get an error of range out of

  Or do I have an option to hide the unnecessary columns (not set their width to 1, it's very ugly-looking)?

  Please help me (())

  Hello rovnyart!

  1. removal of columns in the table:

  I suspect that the reason why you get the out-of-range error is due to fact that in your loop, you delete the columns in the table, you'll eventually end up by referring to a column that no longer exists, because the other columns before it have been deleted. While you remove each column of your table in the loop for example, the column index number will move, because you deleted the other columns in front of her.

  To resolve this, even if you delete a column in your loop, make sure that you take also into account that the index of the column is moved because of the removed columns.

  2 hide columns in table:

  You can use the ATTR_COLUMN_VISIBLE attribute to hide columns in the table:

  3 alternatives:

  Note that another alternative would also use a tree instead, control as the tree control also supports the hidable columns:

I want to convert the long row of data and then start a new column every 50, 100, 5 points (user-defined).

  Using the data from the file, you can reshape everything simply (as you already!), followed by transposition (since you want columns instead of rows). 2D arrays must always be rectangular, so the last column is filled with zeros if necessary. Is that what you want?

  

  Of course if you try to add a new column in a file, that will not work. You can only add lines in an existing file because of the way the data is organized. To add columns, the entire file must be read, intertwined and all re-written new data in the file.

• How can I insert a number to a specific index (row and column) to a table

  I had the most with function 'insert into array' problem because of its counter-intuitiveness. I want to insert a number I got inside a loop IN a table. The ROW and COLUMN of this table I want enter the number is specified by the number of loops of two loops FOR. It did not work.

  So, I have isolated and tested this function further. Frankly, I initialized a table 2D with ZEROS and plugged into the "insert into array" function (on top of entry). I then put the number '1' for the index (line) and the number "2" for the index (column) and then put the entry number "6" for the "new item/sub-table. Then, I hung a picture of 2-D (indicator) output to the output of the function "insert into array. When I did all that, it means I want to just put the number '6' in line '1' and the column '2'... This isn't letting me do it.

  How can I do this SIMPLE?

  Hi Darrell h...,

  Looks like you can use the function "autoindexing. Take your value and connect it to your loop, it will be a default autoindexing. Right-click on the last tunnel of output and select Create indicator, the result is your table.

  It will be useful.
