HOW to add an attribute to the existing node?
HelloI have a question - is possible to add a NEW attribute to existing xml node registered in xmltype?
I found no such a possibility.
I need to use the update! :)
I have: < tag > < tag2 / > < tag / >
I want to have < tag value = 1 > < tag2 / > < tag / >
THANKS IN ADVANCE! :)
With insertChildXML:
SQL> with t as (
2 select xmltype(' ') doc
3 from dual
4 )
5 select insertChildXML(doc, '/tag', '@value', 1)
6 from t
7 ;
INSERTCHILDXML(DOC,'/TAG','@VA
--------------------------------------------------------------------------------
Alternatively, in 11.2.0.3, updated XQuery:
select xmlquery(
'copy $d := $doc/tag
modify ( insert node attribute value {$val} into $d )
return $d'
passing t.doc as "doc"
, 1 as "val"
returning content
)
from t
;

No idea how to loop and add the value to the attribute of the xml node?
I work on a lot of flattening of project using a watched folder.
I have a process parent to locate the directory and call a sub-process to flatten PDF files.
I want to write the directory failed to XML.
If there are several directory failed locations and if I want to add it to the node, he doesn't let me do.
If I set the Xpath location like/process_data/outputXML/flattenDirectoryRequestMessage/failureFileLocation[x]/@path it gives me invalid character exception. I use 'x' for looping and incrementing.
If I do not use the [x]. The directory is overwritten.
No idea how loop and add all the directories failed to attribute of the xml node?
I understand that you can not browse the xml code to assign the value at each node. Rather you can assign only one time to the node.
I realized that it is not possible to do it this way. Then concatenate it as strings, and then attach to the xml once.

I use the full version of DASYLab 8.0, how to add PID module in the design of the façade (window layout)? while I can vary the p, i, d values in the window layout
To do that you will need to change the varibles PID values and then use the sliders to add numbers to a latch for variables that point.
This is how I think it works in Version 8.
In all cases, you should move on to 12 more stable summer.
In addition, unless that is a very slow process, I generally do not like closed loop PID with DASYLab due to the fact that computers is not reliable with timing.

}Hi Piya,
I run your code, and according to your logic that it works correctly.
It's adding that line only once because according to your logic that one line can be added to MDT, if you do not want to add line on each click on the button, follow these steps:
selectedindex1 = chart [obj1.getSelectedIndex ()];
selectedindex2 = shade [obj2.getSelectedIndex ()];
selectedindex3 = rolls [obj3.getSelectedIndex ()];
selectedindex4 = cuts [obj4.getSelectedIndex ()];Lbl1 LabelField = new LabelField("");
Lbl2 LabelField = new LabelField("");
LabelField lbl3 = new LabelField("");
LabelField lbl4 = new LabelField("");
If (LBL1. GetText(). Equals("") | LBL2. GetText(). Equals("") | lbl3. GetText(). Equals("") | lbl4. GetText(). Equals(""))
{
LBL1. SetText (selectedindex1);
LBL2. SetText (selectedindex2);
lbl3. SetText (selectedindex3);
lbl4. SetText (selectedindex4);
GFM. Add (LBL1);
GFM. Add (LBL2);

How to add 2 points on the letter e in the Noel case? I don't have the 2nd series of digits to the right of the keyboard. Windows 8

You mean you want the e character? These two points are called a
umlaut. You do not add points; the e with points is another
a simple e character. There are several ways to get this
character, but a simple is to hold the ALT key and type 137.As a point of information if you are interested, the subject of a
umlaut is to indicate that the second of the two successive vowels is
pronounced separately. So the word 'book' is pronounced buk, but the
Book name is pronounced BO - ock. -

How to add two lines when the second row is not visible, but also gets the first data line too?
I want to add two lines like below picture, but want the second to remain invisible.
I asked this question but my way of asking was wrong, that's why for me once again.
Concerning
Try to follow these steps:
1. in the database table to add the new column "JOIN_COLUMN" and add the new sequence "JOIN_SEQ".
2. Add this new column in the entity object. (You can add this in entity object by right clicking on the entity object and then select "Synchronize with database" then the new column and press on sync)
3. in your bookmark create button to create only one line NOT 2 rows.
4 - Open the object entity--> java--> java class--> on the entity object class generate and Tick tick on the accessors and methods of data manipulation
5 - Open the generated class to EntityImpl and go to the doDML method and write this code
protected void doDML(int operation, TransactionEvent e) { if(operation == DML_INSERT) { SequenceImpl seq = new SequenceImpl("JOIN_SEQ", getDBTransaction()); oracle.jbo.domain.Number seqValue = seq.getSequenceNumber(); setJoinColumn(seqValue); insertSecondRowInDatabase(getAttribute1(), getAttribute2(), getAttribute3(), getJoinColumn()); } if(operation == DML_UPDATE) { updateSecondRowInDatabase(getAttribute1(), getAttribute2(), getAttribute3(), getJoinColumn()); } super.doDML(operation, e); }
private void insertSecondRowInDatabase(Object value1, Object value2, Object value3, Object joinColumn) { PreparedStatement stat = null; try { String sql = "Insert into table_name (COLUMN_1,COLUMN_2,COLUMN_3,JOIN_COLUMN, HIDDEN_COLUMN) values ('" + value1 + "','" + value2 + "','" + value3 + "','" + joinColumn + "', 1)"; stat = getDBTransaction().createPreparedStatement(sql, 1); stat.executeUpdate(); } catch (Exception e) { e.printStackTrace(); } finally { try { stat.close(); } catch (Exception e) { e.printStackTrace(); } } } private void updateSecondRowInDatabase(Object value1, Object value2, Object value3, Object joinColumn) { PreparedStatement stat = null; try { String sql = "update table_name set column_1='" + value1 + "', column_2='" + value2 + "', column_3='" + value3 + "' where JOIN_COLUMN='" + joinColumn + "'"; stat = getDBTransaction().createPreparedStatement(sql, 1); stat.executeUpdate(); } catch (Exception e) { e.printStackTrace(); } finally { try { stat.close(); } catch (Exception e) { e.printStackTrace(); } } }

How to add a space between the currency symbol and price?
Hello
Can you please guide me how to add a space between the currency symbol and price?
Support told me this question in the forums because it is done with JavaScript and it is not covered in the official documentation.
Any who have done this? I would like to turn 20 at 13.20 RON RON13 or 32, 90 to 32,90 USD.
Thank you!
Hello.
I test and it works.
If any who need it, this is how I did it.
I changed the models of Modules-> page layouts of the shop online-> overall layout.
I added at the end of the HTML code, the code following JS:
$(document).ready(function(){
$('.newprice').each(function(i, el){
var valoare = $(this).html().substr(10);
$(this).html('
Pret: ' + valoare + ' RON')})
$('.oldprice').each(function(i, el){
var valoare = $(this).html().substr(3);
if($(this).html() != ''){ $(this).html(valoare + " RON") }
})
})
The result can be seen here: http://magazindepiese.worldsecuresystems.com/accesorii/chimice?Page=1&Items=12
Instead of PRICE: RON22, 62, now it's READY: 22,62 RON that is correct for the Romania.
Thank you Mario!

Windows Media Player-how add audio files to the existing selection
Editing of existing playlist in Player 12 - great pain
In previous versions of media player, I could drag a song to a windows explore Panel directly in a playlist. so adding media was a nod to a playlist. Now, you must open it in the game Panel, add media, and you MUST CREATE a NEW NAME FOR THE list of READING which is ABSURD! In other words you can not change the playlist, click SAVE, and the playlist that you work is registered. You should always create a NEW name. What I do is add a '1' to the old name, create the NEW name, and then I have to go back and remove the old list. Once again. It is ridiculously heavy. Can Microsoft fix this? Everyone is significant pain is?
Original name? If you change an unregistered playlist, then it doesn't have a name yet. It is quite normal that you must enter a name when you click on save the list for the first time. The next time you save, you will not have to enter a name more (because then it's not playlist not registered).

How to add form fields to the form of attributes
Does anyone know if the channels of its possible to add the custom text in the form of attributes in a list (product great view) product.
I created a checkbox control in a new attribute of product but this box has also two string text fields I need to insert that will define the object checkbox.
i.e.
CheckBox checked = | String [name] | text string [number]
Thank you
Wayne
You want to use is the field of details of capture.
When you check on a product and you have this tag in the layout, it will make a text box.
You can use this for details of captcha that come through the order in the system.
If you have several fields for different things, you can create those of the disposition of the proceeds, CSS hide the data text box captcha box and fills with javascript based on the field that you create.
You can also add new fields to your web form to the registration form buy as its functionality is still a custom web form. You can add to that in the admin, update the registration purchase arrangement with the shape that they include those. You can create those to be both custom fields CRM, if you
