A loop in exonentially duplication line selector

Using Apex 4.2

Background

Created a tabular presentation based on a view. Removed all updates of several default lines and destruction, buttons and processes.

I use a tabular form due to the fact that I can access a line selector.

The data in the row itself are all read only so it is a report with a line selector.

It's because I can't find a way to select a line interactive report, well I can and did, but it's a work around.

Problem

I created a button to process the selector to run the code below:

begin
kdm_adm_utils.log ('Page', 'XKDM: WF: Current Development', 'Selected Check Boxes:'||wwv_flow.g_f01(1)) ;
kdm_adm_utils.log ('Page', 'XKDM: WF: Current Development', 'Selected Check Boxes:'||wwv_flow.g_f02(1)) ;


   for i in 1..wwv_flow.g_f01.count
   loop
   kdm_adm_utils.log ('Page', 'XKDM: WF: Current Development', 'i:'||i) ;
      kdm_adm_utils.log ('Page', 'XKDM: WF: Current Development', 'WF ID:'|| wwv_flow.g_f02 (wwv_flow.g_f01.count)) ;
   end loop;
end;

I just wanted to see what would be output. For a line it works oddly and I can't find the ID based on the line

When I select multiple lines in the loop executes the wrong for the number of lines but manages also to the number of selected lines.

So if I've selected three lines this above procedure would go three times, each time to loop three times.

I put the scope of execution: created for and changed lines in the State of the button that is displayed.

Mandatory

I only want to loop through the selected lines once by click of a button

Know what line I'm currently traveling.

Really would appreciate some sort of entry here.

The problem is not with the loop. It works perfectly. The problem is that it happens for the same number of rows are selected. I got around the problem with a global variable that I put and don't forget to run only loop once. Bit inefficient but still to learn the inner workings of the APEX

(Editable report) SQL query with line selector
I used this code to get the update of the records in a query SQL (editable report).
Updates a value in a selection box.

because me in 1... apex_application.g_f01. Count
loop
UPDATE CONTRACTS
SET LOAD_FLAG =: P8_SELECT

Here's my dilemma.
Line selector seems to be in a fixed position.
By linking the line for identification number selector (1, 2, 3, etc.)
Sort by ID (1, 2, 3, etc.)

It works perfectly, as long as the ID is sorted in order. < <
If it is sorted by another field with say ID 29 now in the 1st row, by checking the box and update, you update ID #1 located elsewhere on the page.
Any ideas how to make the line selector literally equal to the line, it is displayed in?
Thank you

I think I have an idea of what is wrong and, eventually, how to fix it. Try this:

make your field primary key (NO ROWID!) in a column in a table column, either through the "wizard" (i.e. through the report attributes screen), or using the APEX_ITEM api (as described by Vee). I often have my primary key as a hidden; If you really need to see it, you can use "DISPLAY_AND_SAVE".

So if your primary key 'ID' colum is now in the 2nd table as a table (i.e. f02 - adjust accordingly!), your PL/SQL process should look like this:
```
for i in 1 .. apex_application.g_f01.count
loop
   UPDATE CONTRACTS
      SET LOAD_FLAG = :P8_SELECT
    where ID = apex_application.g_f02(apex_application.g_f01(i)); 

end loop;
```
It of a little confusing at first but it it makes sense when you train how tabular tables work with check boxes. The length of this array represents only what is verified - so if you have 3 values checked, the cardinality of the table in a particular table 3. On the other hand, your other tabular berries (containing the 'normal' values) has a cardinality of the count of all the visible lines.

In this case, the record selector (F01) contains the ID of the relevant line in your report - so passing this value in the array index 2 (F02) should give you the correct primary key for that particular line value. If you subsequently order the report by another field, it should work again.

I should add that Vee method will work well - the difference is that, instead of organizing the rowid, f01 contains the actual key value. Hope this helps

How to identify line selector in a process update on the page.

I want to update some columns with a value of an area of selection on the page.

With the help of the base:

Now sure how to identify [line selector] and/or validate it is checked.

Identify the name of the checkbox of the source of the page element, it should be of the fxx format (f01, f02... f50).
Suppose that we f01.
```
for i in 1 .. apex_application.g_f01.count
loop
  UPDATE CONTRACTS
  SET SIP_LOAD_FLAG = :P16_STATUS
  where  =  apex_application.g_f01(i); --i'th checked record' primary key
end loop;
```

Is it possible to programmatically control line for a line selector?
Greetings,

I have a report that contains the line selector column. I'm processing lines which are activated by the user when he clicks on a button, so I'm already a loop through FOR ii IN 1... Apex_Application.g_f01. COUNTY.

I need some lines to always be dealt with in the loop, so I would:
1 have some lines checked automatically. Is this possible?
2. using the same logic that automatically checks some lines, I also want to make sure they remain activated, or processes in the loop. (You know, I can check automatically certain lines, but the user can disable the). So, even if the user does not check them, I would check a program before the second FOR IN 1... Apex_Application.g_f01. COUNTY loop occurs.
3. If it is possible to prevent the disabling of a line that is automatically checked it would be great and would mean that requirement 2 is debatable. If possible let me know. That would be sweet. :-)

I hope that makes sense, and that you understand what I have to do. If this is not the case, let me know.

Thanks in advance for your help, Tony
This should work:

htmldb_item. CheckBox (2, ecn_approval_master_id, Decode (Mandatory, 'Y', 'disabled', null), Decode (Mandatory, 'Y', ecn_approval_master_id, null))

This should give you something to think about :)

How to upgrade the value of line in a report by using the line selector (check box)
Hello

I have a requirement where I need to make PLSQL update process on a specific line in my report.
Based on the line selector (marked) the plsql process update on the values of the selected line.

I have to update status of the employee selected as 3.
But regardless of the choice of line selector, juice processing SRM application in a sequence that is., this is row selected, application takes the first line and updates the status.

My update process from looks like this:

BEGIN

BECAUSE me in 1... apex_application.g_f01. COUNTY - checkbox
LOOP
If apex_application.g_f01 (i) only IS NOT NULL then - box marked
insert into values TEMP_T (apex_application.g_f03 (i), V ('APP_USER')); -f03:Deptno
update status set Table_x = 3 where deptno in (select deptno from TEMP_T where rtrim (lower (apex_user)) = rtrim (lower (V ('APP_USER')));
delete from TEMP_T where rtrim (lower (apex_user)) = rtrim (lower (V ('APP_USER')));
end if;
END LOOP;
END;

Once the user selects the line selector, application needs to update the status of this particular emp 3 in Table_X.
Currently, if I select a line, using the line selection box, my update process changes the status of the first record line. If I select three rows, then my first three rows updated.
So I have to update the particular line or selected using the selector (checkbox) row lines

If you could help me solve this question would be really appreciated.

Thank you

For loops with the cursor line and indexing

Hi all

I have a question about the loops with the cursor, line and indexing.

How can I scan via a cursor with an iterator?

I would use an iterator as

Whole LoopIndex;
Whole LoopIndex2;

for LoopIndex at the beginning of the cursor at the end of the cursor
loop
line =: cursor [LoopIndex];
for LoopIndex2 of LoopIndex at the end of the cursor
etc...
end loop;

I need to use an iterator because I need to use a nested for loop.

OR

How can I solve the following problem?

Class name % ofClass average test Score
1 Niobe 7 8 8.4
1 alena 4 7 7.5
1 9 7 8.9 Estia
1 Lilly 10 8 9.8
1 Sandra 6 8 8.3
1 Melanie 8 8 8.1
Nadia 2 8 3 4.4
Sayuki 2 9 8 8.4
Diasy 2 7 8 8.0
Flower 2 7 8 6.5
Diana 2 6 8 7.3
3 Flora 7 8 5.8
Sukiya 3 4 8 8.4
Samantha 3 10 8 7.7
Roxanne 3 7 8 6.9
Eline 3 8 8 7.4

I need to
-By class, I need to recalculate each average people
-By class, I need to calculate the % of class score (sum averages / people in the class)

So it can be done in a nested for loop?
Or do I just step by step?

Well, based on this information it would be something like...

Using the line selector
I have an updated report in which I added a line selector. I can't find information anywhere where I can reference columns that have been selected. What I want to do, it's the user selects some lines, and then click a button. Then update a field on each of the selected lines.

In my opinion, this is probably a simple act, I can't find documentation on how to do.

Thank you.

Tabular form line selector to hide for some lines?
Hello

I was curious, if it is possible to hide the selector box in line for certain items? For example
If a value is of a certain column in a row I want to hide the box and display it in other cases...

Thanks in advance!
Hello

This setting works only for an entire column.

There are at least three possibilities:

1. create the box using APEX_ITEM. CHECKBOX (see: [http://download.oracle.com/docs/cd/E10513_01/doc/apirefs.310/e12855/apex_item.htm#CHDDCHAF])

2. create a custom report template "Named column (model line)" - where you can define the layouts for each line the conditions up to 4

3 - using javascript to analyze the data in other columns and disable or remove the boxes where required

Option 1 is probably easier, but you need to remove the line selector of the report that it is no longer necessary

Display the number of lines based on a line selector
Hello

We have a form on an sql query. We are currently showing 100 lines per page. We would like to have a line selector, so the number of lines displayed on the page depends on the value selected in the line selector. I'm not sure how this is possible.

Thanks in advance,
Hello

It is relatively easy to set up - see: [http://apex.oracle.com/pls/otn/f?p=267:111]

There are 4 steps to create this feature:

1. create a "select list with Submit" on your page called, say, P111_ROWS. The source of the list value:
```
STATIC2:10;10,20;20,50;50,100;100,200;200,500;500,1000;1000,All;1000000
```
(Of course, you can change these values according to your needs)

Display Set Null and display additional values to no.

2 create a calculation on your page that defines the new element value static assignment of, say, 10. This calculation should depend on the element is null (this simply sets a default initial value)

3. create a branch of page that links to the same page and check the option reset Pagination

4. on attributes of the region of your report, enter the name of your new item in the parameter 'Number of lines (element)' - I also clear the value in the parameter 'Number of Rows.

This should be it!

SLQ: A loop with the select line, counters and variables
Hello!

I have a bit of a pickle SQL and would be very happy to any experienced help.
I have a big enough table that contains two columns in particular (illustrated by a few examples)

REFERENCE
Mouth Med Chem (2008) 16, 1111-1124
Bioorg Med Chem Lett. 2008 may 1; 9:2820 - 4 EPUB 2008 Apr 4
BR J Pharmacol. In February 1999; 3:665 - 72.

2_ YEAR
1996
2001

Sometimes, the two columns are null. What I want to do, it is to loop through the table and pull on the date of the REFERENCE column and update the YEAR_2 column with it.

My current code snippet is as follows:

declare
x number: = 1995;
cursor s1 is SELECT rowid, t.* FROM CB1ASSAYS t WHERE REFERENCE like "%x % ';
Start
While x loop < 2006
C1 loop s1
Update CB1ASSAYS set YEAR_2 = x
where REFERENCE like "%x % ';
x: = x + 1;
end loop;
end loop;
commit;
end;
/

However, it doesn't seem to work properly. He updated lines with 1995 in the year, but no date higher. Curiously, he updated a number of records with the year 2064, when there was no 2064 anywhere in the REFERENCE entry.

There are no errors encountered when I run this script.

Any idea?

Thank you!
In your code the where conditions update should be:
```
WHERE REFERENCE like '%'||x||'%';
```
and you can get rid of the slider at all:
```
declare
 x number := 1995;
begin
 while x < 2006 loop
   update CB1ASSAYS set YEAR_2 = x
   where REFERENCE like '%x%'
   AND YEAR_2 is null --To update only null years
   ;
   x := x + 1;
 end loop;
--commit;  IT's better you you commit after checked if all is ok...
end;
/
```
