Select with LESS vs two VARRAYS with MULTISET
Hi allI just wanted to know, which one of the two following is faster and results in better performance.
1. SELECT statement containing 200 + columns in a Table with operator LESS. (TWO SELECTS with operator between them LESS)
2. loading of the individual SELECT statement (with some LESS) result sets in two different VARRAYS and then use these two operators of type MULTISET.
That one is faster and uses less memeory?
Thank you
REDA
Direct SQL is still fast compared to the PLSQL. When you use varrays, there will be change of context. Even if you use Bulk collect for loading data yu have to put a limit of 1000 and not beyond.

List of selection with zero value Submit reset
Hello
I have two list of selection with new submission namely A and B, both are dynamically filled with SQL query. The 'B' selection list is populated based on the value selected by the user from the list "A".
The problem comes when the user has selected a value from list "B" and by changing the value of 'A', the current value of the 'B' list indicates the value selected previously.
I'm new to APEX would be grateful if you could tell me How to reset the value of 'B' list when 'A' is selected.
Thank you
Spengler.Your list for ITEM B should allow a null value and the only other thing is to have a conditional process that fires when the request is POINT A. This process must assign POINT B null.

You can try this IN operator

Note: This is not tested in the Sqlite database.
But successfully performed in the other RDatabase.

Multiple selection with binding variable error
Hello world
I tried to put in place an array of adf multiple selection with another table, by following the tutorial (http://www.oracle.com/technetwork/developer-tools/adf/learnmore/75-multi-parent-row-detail-views-328078.pdf), page 3.
I created all things and first of all I had an exception error, which I fixed, but now, whenever I try to select multiple lines, it won't update the table of the adf.
In this example, I choose a service line and it shows the emplooyes, but every time I try to choose another line by ctrl clicking on it, the employees table be updated.
Since I tryied to follow the tutorial, I'll put the code for the bean, I created for this purpose (it's a little different than the code given by the tutorial, but only because I had to get rid of the exception error)
I use jdeveloper Studio Edition Version 12.1.2.0.0.
Here is my code for the bean.java:
Select listen port defined for the departments table. The selected line keys are read in the reference table.
For each line, the Department ID value is read and added to a string buffer that generates a comma-delimited
List of the departmentIds. In the end, this string is passed as an argument to the link of action ExecuteWithParams
{} public void onDepartmentTableSelect (SelectionEvent selectionEvent)
variable to hold the string containing the selected set value line departmentId
StringBuffer departmentIds = new StringBuffer();
Go to the main table to read selected line keys
RicheTableau rt = selectionEvent.getSource ((richeTableau));
RKS RowKeySet = rt.getSelectedRowKeys ();
Iterator selectedRowsIterator = rks.iterator ();
memorize the current line to place it back in the end key
CurrentRowKey () rt.getRowKey = (list);
for each selected master line, determine the departmentId
int size = 0;
{while (selectedRowsIterator.hasNext ())}
size ++;
The rowKey () selectedRowsIterator.next = (list);
each value is terminated by a comma
If (departmentIds.length () > 0) {}
departmentIds.append(",");
}
take the current line
rt.setRowKey (rowKey);
JUCtrlHierNodeBinding wrappedRow = rt.getRowData ((JUCtrlHierNodeBinding));
Line rw = wrappedRow.getRow ();
/*
Number departmentId = (number) rw.getAttribute ("DepartmentId");
*/
int departmentIdInt = rw.getAttribute ("DepartmentId") (Integer);
oracle.jbo.domain.Number departmentId = new oracle.jbo.domain.Number (departmentIdInt);
departmentIds.append (departmentId.stringValue ());
}
back the foreign currency on the line
rt.setRowKey (currentRowKey);
Run the query on the detail table
BindingContext bctx = BindingContext.getCurrent ();
BindingContainer links = bctx.getCurrentBindingsEntry ();
OperationBinding executeWithParams = bindings.getOperationBinding("ExecuteWithParams");
executeWithParams.getParamsMap () .put ("departmentIds", departmentIds.toString ());
executeWithParams.execute ();
refresh the detail table
AdfFacesContext adfFacesContext = AdfFacesContext.getCurrentInstance ();
adfFacesContext.addPartialTarget (employeeTable);
}
}
If someone has an idea of why it isn't updated table, please answer. Any idea can help.
Thanks in advance.
Greetings,
Frederico Barracha.
Finally, I found the problem...
The problem was that I had to remove a line in the properties of my table, the property services: selectedrowkeys, because he only spent the last selected row.
Yet, I apreciate the help and I had to replace a code in the bean.java, in reason of the exception error and you had to do. Maybe I did a configuration in the wrong way and he would not.
Thanks for the help.
Kind regards
Frederico.

Cannot set keyframes in the audio clip selected with the pen tool - cannot see even the line volume control more to set keyframes on having developed the clip. What could be the problem? I use the first CC pro @.
You can use the Ctrl key and then click with the regular selection tool, clicking with ctrl will make a new keyframe. in this way, have no need for the tools. CTRL has other great shortcuts that will stop you having to spend retouching pads tools too.
If the automation keyframe line is missing, you can switch on and off in the menu sequence.

The Central handle on the rectangle isn't gone when I select with the black arrow (v) tool. See the bounding box and the edges is both. Dd intermediate anchor to go?
haggyabeken,
I'm afraid that you have come across the Rectangle Live bug, which is limited to MAC versions starting from 10.7 and 10.8, but not 10.9 (Mavericks), see this thread linked below.
https://forums.Adobe.com/thread/1595973
Thus, a switch for the Mavericks with a reinstall might be the way to solve it here and now.
To get around it, in each case, it is possible to develop direct Rectangles to get the normal old shaped rectangles or Pathfinder > unit, or use the scale tool.
A more permanent way round that is to create normal old shaped rectangles, after running the free script created by Pawel, see this thread with download link:

Why a quick selection is clear my selection with second click?
I click the selection with my quick selection tool and then when I click again to continue to select more, the second begins to remove my current selection. I know now removes it key 'option' my selection but I don't hold the key 'option '. It starts just do it when I do my second click and continues then withdraw even if I continue to click. I've just updated Photoshop but that did not help. I have Photoshop CC. Help, please.
This is probably caused by you after clicking on the button "Subtract from selection" at some point in time, in the settings of the tool, see photo. If you have no selection when you start using the tool, it will create one, but as soon as there is an active selection tool will begin to subtract. Each tool of the PS remember its settings! As suggested by Pierre, reset your tool will solve this problem or just by clicking on the button "new selection". It can be a pretty good idea to reset your tools, the first thing you do every day a new working session in order to avoid such problems when starting.

make a selection with an alias
I have a lot of images which have been made out of 3DS MAX. A long time ago that I recorded an action to do an alpha channel, use it as a mask and save it as 2 different file types. Worked very well. Now, I need to open a bunch of them and somehow, get rid of the anti aliasing around the image. I need jaged edge. I did some how in the past using threshold (I think), but can't for the life of me what I've done. Any ideas on how to make a selection with an alias?
Thank you
Dean
You have an alpha channel, which has levels of grey in it?
Simply use the threshold on this alpha channel.

White on white selection with the magic wand of refining
I'm trying to remove the background of a picture of BW - one model posing in front of a white background.
Select with the magic wand works fine except on the area where the light on the model wears the white skin. When I choose, I get the hand and the lower part of the arm (see below) but miss the box top, completely white. I tried all kinds of settings and also tried to increase the contrast with a brightness/contrast layer, but nothing I I understand allows me to keep the arm and remove the bottom with the arm. FWIW, the image cannot be redone.
How can I do? Thanks for any help.
EdB
Learn how masking... Also in white when mixed in a layer with the blending mode multiply does not change. So, if you add a new layer on top of your image and set its blending mode to multiply. You will see your arm starts to show through. Add a maske layer to this layer and paint with black to show the lower arm of the layer by hiding the top layer on the arm area.

XPS 8700 Hard Drive failure - after less than TWO WEEKS
I'm a little frustrated. I recently ordered a new Dell and XPS 8700 office. Everything seems to work well. Then yesterday I walked away from my office for 5 minutes, and when I came back, I got a screen saying my computer could no longer starts. After spending some time on the phone, we confirmed what I already suspected, that my hard drive has failed. This was after less than two weeks! Is this a common problem with the recent Dells? I am certainly not happy having to wait several days understood of the technology that will be (according to the support person) that I spoke) an appointment to install a new hard drive. I'm more frustrated that I'll lose data, installed applications and settings that I have spent the last two weeks on. I assumed that if I had to look on the bright side of things, it wasn't months or years of work that was lost, but I fear that the replacement of the HDD will suffer the same fate on the road, making me lose a lot more work. Besides than to spend the money to set up a backup system, how to avoid this problem in the future? And what is the level of reliability of hard disks installed in the 8700 s XPS?
Dell uses a variety of brands of hard drive of their computer. HGST, WD, Seagate and Toshiba are trademarks used. Your next hard drive could be one of those, there is a chance it will be different than what you have now. As with all hard drives, they will be eventually. some quickly, other overtime. I wouldn't worry about replacement drive failure. If so, check and see if it was the same as the previous disc.
