• How to retrieve several values an adapter DB to a Web Service

  Hello
  
  I create a connection WS who receives the user name and password and returns the status of the user, the full name and a set of permissions (the number of permissions varies between users).
  
  To do this I created a DBAdapter who calls a PL/SQL procedure. This DBAdapter is connected to the Web Service connection through a mediator.
  
  I have two problems:
  
  1. I don't know the type of variable that the PL\SQL procedure must return. As I said I need to retrieve any number of values in a table (the user's permissions). How can I do this inside a PL\SQL procedure? What sort of structure I would stay?
  
  2 - How can I assign a variable of multiple value (the variable of permission) in the Ombudsman? Is the Ombudsman going to identify it as variable is multiple value and automatically add a for-each statement?
  
  
  The version im using Oracle DB is the 11.1.0.7.0 and the Oracle SOA Suite 11.1.1.3.0.
  
  Thanks in advance,

  You can generate an XMLType (of a VARCHAR2 variable, so) within the PL/SQL procedure. Please see-

• fill out question of XML attributes

  I've got an XML file like this:

  As you can see, I have two packages.  I was able to get Labview to read in an array of child node two, but now how do I read in the attribute as an array or a collection of record for each 'proto' and then get the data only.  For example, I would like to retrieve data from the #2 package and it should produce a "EF: AA:FB:0. "C: 0d", how can I do this?  I know how to retrieve a single xml file, but get to the part of the attribute is a bit difficult here.  Thank you

  Oh!  This one is new for LV9.  I'm sorry.  Here is a variation using .NET (next you tell me are you on Mac).

• I don't have my key code for windows. My dealer doesn't have either. How can I retrieve the key code number?

  I don't have my key code for windows (registration card was not with the computer when I bought it).  My carrier apparently deleted the key during my computer repair code.  My retailer where I purchased the computer didn't either.  How can I retrieve my key code number?

  The Windows product key is usually displayed on the sticker on the underside of the computer.

  However, you can also get it by running the Belarc Advisor or the Magic Jellybean Key Finder.

  Google for one of those and you will find them.

• How to normalize/linearize whitspace in XML attributes?

  Hello

  I have data in a CLOB column I need to appeal to an XML attribute. The data may contain CR, LF and tabs - that the XML must be preserve way standardized/linearized (that is to say using & #10; & #13; etc.)

  I tried using XMLROOT - it deletes the line a total break.

  I tried to use XMLSERIALIZE - when finished with clause VERSION it also suppresses the newline, when without the VERSION, it keeps the jump line but not standardized.

  Do not use these preserves the jump line - but not standardized.

  Is there a bed in order to standardize XML - or should I use replace nested?

  Examples below.

  Thanks in advance.

  Question still pending, if anyone has another way - or knows for sure replace is the only option.

  Replaces nesting calls is probably the only option, of course, but not the way you have tried in your examples.

  Do replace it at an earlier stage, directly on the data source.

  Here's how I'd do:

• How to handle xml attributes?

  Hallo,

  I am new to Livecycle and I have some difficulties to understand how reading/identification of the attributes XML in LiveCycle Designer.

  If I drag-and - drop items (#data of display data), they appear without problems. But if I drag an attribute (@attributename) they always show the empty to the PDF.

  For example, I have an XML file that looks like this:

  < product >

  ....

  < price >

  < ParamPrice visible = "true" >

  < prixUn visible = "false" > 1.350,00 < / prixUn >

  < priceB visible = "true" > 1.350,00 < / priceB >

  < price visible = "true" > 20.00 < / price >

  < price visible = "false" > 0,00 < / price >

  < / if >

  < NouveauPrix visible = "true" >

  < prixUn visible = "false" > 1.350,00 < / prixUn >

  < priceB visible = "true" > 1.350,00 < / priceB >

  < price visible = "true" > 20.00 < / price >

  < price visible = "false" > 0,00 < / price >

  < / sonderpreise >

  < / price >

  ...

  < / product >

  I tried to link like this: price.oldprice. (visible.value == "true") .priceA, but it does not work.

  I can´t really find some good information about the manipulation of XML attribute in LiveCycle. Can you please help me or tell me where to find more information on this topic.

  Thank you!!!

  What about Kat

  It is not the relationship between the presence of the object property and your visible attribute to date.

  But you can use a script to create such a thing.

  Put this in the event layout: ready for a text field, you want to be hidden or shown depending on the value of the visible attributes.

  this.presence = this.dataNode.visible.value === "true" ? "visible" : "hidden";

• Unable to get XML attributes in elements with function XMLTABLE

  I cannot get attributes of an XML stored in an XMLTYPE column.  The XML uses primarily attributes rather than items with a value of tag/matching.  If I put the knot in the first argument of the function XMLTABLE, he shoots the attribute at this level.  However, when I try to retrieve the attributes of the child node, I don't get the attribute values.  I'm working on the 11.2.0.3.0 Oracle database version.

  This is the create/insert statements:

  CREATE TABLE XML_TBL_TEST

  (

  ID NUMBER,

  XMLTYPE data

  );

  INSERT INTO XML_TBL_TEST

  VALUES (1, xmltype ("< user >

  < username = "Name1" >

  <>projects

  < Project = '100' QId OpId = PName "101" = "PName1" >

  < group >

  < group GName = "GName1" >

  elements <>

  < point OName = "OName1" Type = "Type1" >

  < ops >

  < op PType = material 'PType1' = 'Mat1"series = PStyle"Series1"="PStyle1">

  < options >

  < name of option = "Name1" Value = "V1" / >

  < name of option = "Name2" Value = "V2" / >

  < name of option = "Name3" Value = "V3" / >

  < / options >

  < /op >

  < op PType = material 'PType2' = 'Mat2"series = PStyle"Series2"="PStyle2">

  < options >

  < option Name = "Conjoint4" Value = "V4" / >

  < name of option = "Name5" Value = "V5" / >

  < option Name = "Name6" Value = "V6" / >

  < / options >

  < /op >

  < / ops >

  < / point >

  < point OName = "OName2" Type = "Type2" >

  < / point >

  < / object >

  < / Group >

  < group GName = "GName2" >

  < point OName = "OName3" Type = "Type3" >

  < / point >

  < / Group >

  < / group >

  < / project >

  < OpId project = "200" QId = "201" PName = "PName2" >

  < / project >

  < / project >

  < / user >

  < username = "Name2" >

  < / user >

  < username = "Name3" >

  < / user >

  ((< / user > '));

  The query below will draw the Name attribute in the element of the user but not the OpId, QId and PName attributes on the child of the Project element.

  SELECT x.*

  OF XML_TBL_TEST t.

  XMLTABLE (-with xmlnamespaces ('http://www.w3.org/2001/XMLSchema-instance' as "xsi"), )

  "/ Users/user.

  PASSAGE t.data

  COLUMNS - ID FOR ORDINALITE 'ID,' NUMBER

  Name VARCHAR2 (30) PATH "@Name."

  PATH of VARCHAR2 (30) PName ' / Projects/Project/@PName',

  QId NUMBER PATH ' / Users/User/Projects/Project/@QId' by DEFAULT 0,

  OpId NUMBER PATH '. (/ Project/@OpId' 0 by DEFAULT) x;

  The following query will get OpId, QId and PName attributes in the child project item.

  SELECT x.*

  OF XML_TBL_TEST t.

  XMLTABLE (-with xmlnamespaces ('http://www.w3.org/2001/XMLSchema-instance' as "xsi"), )

  "/ Users/user/projects/Project.

  PASSAGE t.data

  COLUMNS - UserName VARCHAR2 (30) PATH "@Name."

  PName VARCHAR2 (30) PATH "@PName."

  QId NUMBER PATH "@QId" default 0,

  OpId NUMBER PATH "@OpId" DEFAULT 0) x;

  How can I get all the attributes for a given element in the XML document.  I tried a number of options without success.

  FYI, SM
  
  

  Because there may be several projects under a user, you must use a 2nd XMLTABLE chained (or a more complex XQuery expression) to retrieve the attributes of two orders:

  SQL > SELECT / * + no_merge (x 1) * /.

  2 x 1. Username, x2.*

  Xml_tbl_test 3 t

  4, XMLTABLE)

  5 "/ users/user.

  6 in PASSING t.data

  7 COLUMNS

  Username 8 VARCHAR2 (30) PATH '@Name '.

  9, XMLType PATH "Projects/Project" projects

  (10) x 1

  11, XMLTABLE)

  12 "/ project".

  13 by the WAY x 1. Projects

  14 COLUMNS

  NUMBER 15 QId PATH '@QId '.

  16, ROAD NUMBER OpId '@OpId '.

  17, PName VARCHAR2 (30) PATH '@PName '.

  (18) (+) x 2

  19;

  QID OPID PNAME USERNAME

  ------------------------------ ---------- ---------- ------------------------------

  Name1 PName1 101 100

  Name1 PName2 201 200

  As you can now see the XML contains several elements of the order. For each agenda item, I have a single operation and a brick_id. Then, for each item on the agenda, I have a list of brickAttributes (name and value).

  How can I get something like that?

  OPERATION BRICK_ID NAME VALUE

  As shown, it simply retrieves to a higher level object that repeats once in table x and happening at the table there, which returns the expandable nodes.  The join is managed by value (x) in the second simple table.  It assumes that there is always 1 or several nodes of ns1:attribute in each ns1:orderItem.

• How to remove several Favorites in safari?

  Hi, I was wondering how to remove several Favorites in Safari because I accidentally added thousands of bookmarks.

  To remove several items in Favorites, I'll

  1. Select 'Edit bookmarks' in the menu 'Favorites '. -This shows real bookmark tree structure using the window in the current tab.
  2. View, you can click the triangle to the left of the sub folder name to expand / corrupts.
  3. Then select items to remove using the click, shift-click, or order, etc..
  4. Tap the DELETE key or select "Delete" from the menu "Edit".
  5. Repeat step 2 to 4 for all items you want to delete.

  In the bookmarks view, you can also use drag - move to reorder items.

  After cleaning, you can close the window/tab or just start normal web browsing in the same way as the other web site of switching.

• No idea: sudden failure of several keys on the wireless keyboard

  Hello, I use a wireless keyboard HP, M/N on the back said SK-2060, but this site does not recognize as a model number, so I'm not entirely sure what keyboard model number it is.

  The keyboard has been working well for months, more than a year by this question, I think. Just this morning several key of all isn't on me at the same time, and they are all in the same area. O, 9, f7, and f8 keys are not admissible. I have read some things and thought it might be a driver problem, I uninstalled the drivers for my keyboard and the keyboard no longer works, I re-plugged my wireless adapter and it re-installed the drivers and the keyboard is working again. All the broken keys still don't work.

  I don't think it's a hardware problem, none of the buttons seem as if something is stuck sub, or obstructed in any way. All of them worked very well last night, now they have suddenly stopped and they are all in the same general area of the keyboard.

  I was wondering if someone could help understand me what went wrong, or how I might be able to fix it.

  I have a new keyboard for the moment, but it is not as comfortable as the keyboard HP that I use, and I would be able to fix it if I could.

  Thanks for your time, read this
