Can a Xquery return a concatenated string and an XML element

• Preserve the font properties after concatenation string and control update

  Is there a better way to do it?  My method is unusably slow.  I played with several options (making assumptions of words separated by a space with the same fonts info, etc.), but I have not really found something that I am satisfied.

  

  David, updates FP method.  You update the text character by character properties. empty them in the buffer of transfer and update all at once.

• Function - return multiple values in a concatenated string

  Hello
  
  Is it possible for a function return a concatenated string (combining more than one number). I'm trying to return the purchase by the introduction and invoice_id number and code order number, but an invoice_id can have several PO with the same code number. I want to concatenate the PO numbers with commas, for example
  
  10124, 10090, 10987
  
  At the present time, the function returns NULL for those cases that have more than one purchase order number.
  
  Thank you

  func_get_po(i.invoice_id, cc.code_combination_id) "PO No",
  func_get_po_requester(i.invoice_id, cc.code_combination_id, func_get_po(i.invoice_id, cc.code_combination_id)) "PO Requester",
  

  Of course, this can be done without any problem.
  If it returns NULL, then you must debug function and check the operating logic. I know that it will take a little of your time, but not problems with the logic of syntax and concatenation.

• I HAVE WINDOWS VISTA AND THE SIMS 2 ON MY COMPUTER BUT I TRIED TO INSTALL THE SIMS 3 BUT NOTHING HAPPENED! (CAN YOU BE RETURNED AS SOON AS POSSIBLE!)

  I INSTALLED THE SIMS 2 DELUX, SIMS 3 PETS AND SIMS 2 APARTMENT LIFE. I GOT SIMS 3 PUT HIM IN THE HARDRIVE HE RAN, BUT THE MESSAGE GAME NEVER TO SAY IF I WANT TO RUN IT HELP! PLEASE

  P.S. I HAVE WINDOWS VISTA

  THANKS X

  Welcome to the Microsoft Answers site.

  Well first thing to note - if you have Windows Vista, it is a forum for Windows 7, then you might have more luck in the Vista forum.  But second, you noted that you have installed the SIMS 2 Deluxe and the Sims 2 Apartment life and the SIMS 3 pets.  There are no SIMS 3 pets yet (only SIMS 2 Pets).  So who could have thrown people.

  So now REALLY tell you putting a SIMS 3 disc in?  If so, you must install the program first and sometimes automatic execution does.  You can, however, open a Windows Explorer (press the Windows key, key with the Windows Logo on it, down and self-tapping letter E - keep the E or you'll have a whole bunch of windows to the top).

  Then go to your CD/DVD drive and double-click it.  It can start the car then run.  If not, then you can right click on the drive icon and select EXPLORER and then find the file named SETUP.  If you don't see what he, or see the files, then make sure you have a valid PC version of the game and do not have a MAC version (my kids have committed this error several times while getting the library software).

  See if none of this helps and then after return. Bob Larson Access MVP

  I just installed Lightroom CC 2015 and when it opens after 5 or 10 seconds video flashes up "" look at an overview of Lightroom and its features". It is not possible to cancel or return to Lightroom. I can just click on the play button and after that, Lightroom crashes.

  I uninstalled Lightroom, re-installed, but everything remains the same. After clicking on the play button, the video window is black. I can only kill Lightroom in the Task Manager.

  I use Windows 7.

  Thank you for helping me.

  OK guys, I have a solution. Press escape [ESC] to close the video window. Yes I know... It took less than hour of my time to understand this. If Adobe please, no matter how lucky you could focus on the provision of a useful product, not to invent unnecessary mess that have zero impact on your username? And Holy shit, employ a specialist UX, this is catastrophic!

• How can I print out the string and whole the two together

  Hello

  My requirement is like printf in c statement.

  I have the 32 bit integer data table.

  I want to print in the labview as

  u32Data [0]: 0 x 12345

  u32Data [1]: 0 x 45566

  the same in the code c is

  for (i = 0; i<5;>

• LISTAGG function: "result of concatenating string is too long."

  Hello
  
  I use Oracle SQL developer 3.0.04 version. I tried using the LISTAGG function to group the data.
  

  CREATE TABLE FINAL_LOG AS

       ORDER BY SESSION_DT

  However, I get the error message,
  
  SQL error: ORA-01489: result of concatenating string is too long
  
  Is it possible to go around it, or are there other alternatives?

  Tim Hall has a page on the various techniques of aggregation of chain that guides you through an example of creating and using a user-defined aggregate.

  On AskTom referenced by Tim page, there is an implementation of an aggregation function of string that returns a CLOB that you can use.

  If you want to understand what makes the user-defined aggregate function, it may look a bit complex, especially if you have never looked at object types in PL/SQL. You don't need to understand all the details of the implementation if you use just the code, however, you can simply create the function and use it as you would with any other aggregate function.

• search string and convert whole real or 8-bit 32 bit

  I was hoping to get some advice on how I could search for the following string and convert it to a real number or an integer.  The following data is output as a device ascii characters and I would look for both in each line (starting with 7699,72 seconds in this case) and convert each one to a real number.  Furthermore, I would like to get the integer values in each row (0, but could be 1,2,10,12, etc.) and convert them to an 8-bit integer.  I think that using the template Match followed by analysis of chain would screw that I need, but am not sure how to match in each case. Thank you!!

  What are the characters in the white space between the and the numbers?

  Scan chain can probably not what you want.  Note that in the image space characters include spaces, return carriage, line breaks and tabs.

  Hello

  ORA-01489 is one of these error messages that really means what he says. The error message you posted pretty much sums up the situation.

  What version of Oracle are you using?  (You must still include this whenever you have a question.  See the FAQ forum: Re: 2. How can I ask a question on the forums? )

  From 12.1 of the Oracle, there is an option to allow VARCHAR2s in SQL to be as big as 32767octets.  (The default is 4000).

  Otherwise, if you can't change the code, either do not run. or ensure that the concerned channels are quite short so the error does not occur.

• Can a function returns a cursor?

• Value derived — concatenated string fields

  Hi all
  
  could you please give an example how can I set a value derived from a string field, so that it is values concatenated from several other fields of type string.
  
  Basically, what I want to do is to collect all the keywords in a field.
  
  Kind regards
  Gulnara

  Hey guliflower,

  With the help of a comprehensive rule that I have validated only that it works for me:

  first the pseudocode:

  If CERTAIN CONDITIONS

  value = variable1 & 'separator' & variable2

  endif

  If you are a derivation based on string values in the localdata (e.g. of the metadata contained in a checkin form) then the "#active." FIELDNAME"works well
  Otherwise, you will need to write additional idoc for the channels that you want to concatenate. The "&" is the operator of concat idoc, as defined in the reference guide of the IDOCScript (http://download.oracle.com/docs/cd/E10316_01/cs/cs_doc_10/sdk/idoc_script_reference/wwhelp/wwhimpl/js/html/wwhelp.htm)

  Here's the working example that I used on my test system. I pulled the doctype string and the string of delimited by a pipe in the comments field security group.

  Here's the code I used:

  <$if #active.ddocauthor="" like="" "sysadmin"$="">
       <$dprDerivedValue=#active.dDocType &"|"&="" #active.dsecuritygroup$="">
  <$endif$>

  It derived from the string ' document | public' in my field of xComments.

  This is interpreted as server-side:
  If the current user on this request is "sysadmin" and then take the string value of the field dDocType add a pipe ' | ' character and add the string value of the dSecurityGroup field and then place all of the contents in the xComments field.

  hope that helps,
  Warmly,.
