Retrieving Stuct attribute names

I have a user defined type that is an array of another type. The underlying type has 5 fields. I am able to get their values by using the getAttributes() method, however, I am unable to identify the actual field names.
Does anyone know how to get the names of the attributes in a user-defined type?
My user-defined type comes back through JDBC as a Type.ARRAY. I then use the getResultSet() of the Array class. Next, I use the getResultSetMetaData() of the ResultSet class. That only gives me two columns: Rownum and SYS_NC_ROWINFO$. The latter is of Type.STRUCT. Within the Struct class, you perform the getAttributes() method which returns an array of Objects. From there I can get the values but I don't know how to get the names of the fields those values are representive of. I was hoping to find a getAttributeNames() method, but it doesn't seem to exist.

use oracle.sql.STRUCT and then get the oracle.sql.StructDescriptor from that and get the ResultSetMetaData from that and use the getColumnName() method from the latter to get your name.

How to retrieve child attribute names in XML?

How do I retieve only the child attribute names from the XML.
XML:
<catalog>
     <book>
           <author></author>
           <title></title>
           <genre></genre>
           <price></price>
     </book>
</catalog>Expecting result:
author
title
genre
price
I tried with the SAX Parser and class extending DefaultHandler it returns catalog and book aswell which I do not want to retrieve.
public void startElement(String namespaceURI, String localName,
                                 String qName, Attributes atts) {
               System.out.println(qName)
//this returns catalog and book along with the other attribute names
}

Also, you're still not specific enough. For instance, what if there's another layer before author and title. Do you want that? What about if there's another level under author and title, do you want that? Can those situations even happen?
Do you want nodes at a certain level?
At a certain level and below?
Always author and title nodes, regardless of where they appear?
Always author and title, but only if they're immediately enclosed by book? Or by book<some number>?
Author and title only when they're under /catalog/book?
If you can't specify your requirements precisely, it's going to be awfully hard for someone to help you.

Hi
Just as an aside to the comments above, a scenario we see occasionally is where a desk provides an internal function (e.g. a helpdesk) and you really just want to get the name display (as seen on the handsets) onto the CAD display.
You can do this by doing a reverse lookup over HTTP against CUCM. There are a number of posts around, these should get you started :
https://supportforums.cisco.com/thread/2065114
https://supportforums.cisco.com/message/3024617
A couple of notes:
- It looks up against the directory, NOT the actual calling line. So you can add stuff to the directory to get external callers to show up by name, but should expect the unexpected when you have shared lines (e.g. multipel directory entries with one tel number for whatever reason)
- If you want to do different lookups (i.e. get names back in a different format, get the actual line display name from CUCM, or lookup elsewhere) then you would need to either:
1) Do it via SOAP or another technology from the UCCX script engine
2) Put in a small external web service to do the lookups and allow UCCX to query via simple HTTP
3) Use a DB for the numbers so you can read/write to it from UCCX and regularly update the data from wherever you like

How to retrieve attribute-names (not values)

Hi
I know that I can get all attributes by an XPath expression according to /AA/@* . But since I have a XML document in XMLType and when I use the "..extract( aXpath)" function, I get all the attributes of the corresponding node but as a concatenation of the values. How can I get the attributes names:
E.G.
AA
BB 12.3 /BB
CC 45.5 /CC
/AA
/AA/@* would return 12.345.5, but I need to know "BB" and "CC", any ideas ?

${applicationScope.abc}
or if there is no attribute "abc" in page, request, or session scopes just
${abc}

How to find database attribute names that correspond to page labels

I've been tasked with creating one or more views to be used in creating reports. The users know data items by the labels on pages, not the database attribute names. So my dilemma is how to correlate the page labels to the database attributes.
For example, there's a course details web page. It includes items labeled "Replacement Course", "Inherited Competency Update Setting" and "Attachments", among others.
Focusing on "Inherited Competency Update Setting"... there's no database attribute called that. I've found COMPETENCY_UPDATE_LEVEL, but I don't know if that is it. And is an "inherited" one different than a non-inherited.
I've googled about, and discovered that "Inherited Competency Update Setting" can be set by using a workflow named OTA_COMPETENCE_UPDATE_JSP_PRC and setting an attribute named HR_APPROVAL_REQ_FLAG. Further research has lead me to determine that HR_APPROVAL_REQ_FLAG is used only within the workflow system. I've found in SYS.ALL_SOURCE a package OTA_COMPETENCE_SS with a function that gets that attribute's value. It includes a query against WF_ACTIVITY_ATTR_VALUES which retrieves values of YES_DYNAMIC, APPROVAL, NO, YES or NOTIFYONLY. I've not found any code that uses the function.
Using ALL_TAB_COLUMNS, I'd found COMPETENCY_UPDATE_LEVEL in OTA_OFFERINGS, which contains "APPROVAL" or null. So that may be what I seek, but I can't confirm it.
I also have been unable to find the translation from "APPROVAL" to "Notification, Automatic Update after Approval" (assuming I'm correct and this is the field)
I've found a Training Administration Technical Reference Manual for Release 11i, which contains information about the database, but I've found no corresponding document for Learning Management for 12.1 (Only installation and user guides).
And this is many days' research to find one attribute. Which I'm not certain I've found.
So, in this case in particular, or any case in general, how does one find the database name for an attribute, given the page label's text??
Thank you
Cornell

Whoa, easier than I'd thought...
When the page first shows up, there's the About This Page link, at the bottom, clicking it you get to the About Page.
I noted two sections, Page Definition and Business Component References Details.
I expanded Business Component References Details and found View Objects. There's a list of views used. I was dismayed that the views don't appear to be in the database. Of course, they're camelCased Java names of Java objects, not database names (although sometimes some of the camelCased tokens might correspond to parts of view names). They are, however, clickable and when clicked the definition shows up, and I was thinking that it would take a long while to find what I was seeking.
But... Hit the Expand All link in Page Definition, do a find on page for the desired label, and there it is... a row with the label, view object name and attribute! Pay dirt!
Then go to the Business Component References Details, find the View Object, click it, and there's the view :-) Find the attribute, then the table... easy peasy!
Thank y'all again

Workflow Attribute Names

Answer me this...
When you create a workflow in the Workflow builder, one is FORCED to have the item level and function level attribute internal names to be all uppercase. Fine. So I make a work attr called MY.ATTR.NAME.
But then, in a PL/SQL function, I am allowed to call WF_ENGINE.GetItemAttrText(itemtype,itemkey,'MY.attr.NAME') and it will fail. It will fail because there is no such attribute called MY.attr.NAME and that is because the workflow builder creates all attributes with uppercase names.
Why in the GetItemAttr and GetActivityAttr functions does Oracle not call UPPERCASE on the names? It would only make sense, so that there is a normalized form of attribute naming? Or make the search for attribute names case-insensitive. Looking at the function body, neither is done. Why is that?
Its forcing me to wrap the Oracle-provided functions with my own that call UPPERCASE on the attr names and then call the Oracle functions because I have many users who will be creating workflows and their corresponding PL/SQL functions and I'd like to make it as painless as possible.

Raja,
How does one go about opening an ER? Through my MetaLink account?
I mean, its not absolutely necessary although I would like to see it in a future patch or version. I just didn't understand the logic behind it... Force users to be able to create only uppercased attribute names but when they go to retrieve them, allow any capitalization. That just leaves room for unnecessary errors.

Re: Retrieve operational attributes

Dear all,
Do you have any concrete Java program example using standard Java API provided by JDK1.3.1 to retrieve the operational attributes of a entry stored in Sun One Directory Server?
Thanks!
Calvin

There is no "+" pseudo attribute name that will retrieve all operational attributes in an entry, like OpenLDAP has. You must specify all of the operational attributes you want to get back in your search attribute list. If you need to get a list of all possible operational attributes, you have to query the schema - the attribute definition will tell you if the attributeType is operational.

BC4J Row Attribute Names

How do I go about getting the Attribute Names from a selected Row in BC4J?
I use the row.getAttribute(x) method to retrieve the attribute data, but I also need to know the name of the attribute in the entity (ie EMPID).
null

Heh! Steve! Great presentations by you at Open World.. Thanks.
Thanks for pointing out the 'clean/correct' way of getting the view object's metadata.
I don't think I would've known about this method of getting the attribute info without your pointing it out explicitly in this thread... if I had tried to wrangle it out of the online docs it would've taken hours, since all I could find is a twisty little maze of interfaces and classes going down to the ninth circle of... well...thanks. grin

JAZN-LDAP : retrieve inetOrgPerson attributes from principal object

Hello.
I 've extended callerInfo demo (in OC4J distrib :j2ee/home/jazn/demo) :
1. use of JAZN-LDAP
2. now the servlet prints the "HttpServletRequest.getUserPrincipal()" object attributes (class implementation : oracle.security.jazn.oc4j.JAZNUserAdaptor) : the servlet prints LDAP attributes like user DN, subscriber name, groups member, ....
Is it possible to retrieve other attributes of the LDAP object user (like description, businessCategory) by the java.security.Principal interface ?
Thanks.

Try this
public String getCompanyByUserDN(String userDN) throws Exception
String result = null;
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
env.put(Context.PROVIDER_URL, "ldap://<<LDAP HOST>>:<<LDAP PORT>>");
env.put(Context.SECURITY_AUTHENTICATION, "simple");
env.put(Context.SECURITY_PRINCIPAL, <<User DN>>);
env.put(Context.SECURITY_CREDENTIALS, <<User Password>>);
DirContext dirCtx = new InitialDirContext(env);

Attributes attrs = userCtx.getAttributes("", new String[] {"o"});
result = (String)attrs.get("o").get();
return result;

Uix get Oracle DB attribute name

I have a uix sort event calling a java method. In the java method, I can get the view object attribute name for the column to be sorted from the page event.
I need to obtain the Oracle database attribute name associated with the view object attribute name so I can construct an ORDER BY clause for the sort.
Does anyone know how to do this?
Right now I am trying to get my java program to retrieve the Oracle DB name.
If this is not easy to do in java, is there a way in the uix code I could set a page property for the column selected to be sorted, with the Oracle DB attribute name in it? The idea would be to set the page property with the proper value when someone clicked on the column header to cause the sort to happen.
I really appreciate any help you can give.
Best regards,
Steve

How To Get Attribute Names for a Particular VO

Hi ,
How To Get Attribute Names Of a Vo where I can Set Viewattributname To the Table RN Columns Where I am Adding Extra Columns Based on Some Condn..
So wen i am creating new Column to existing Table RN and we Need to add Attribute Name Also...Rt..
And How To get RelationShip Between Database Column Name and Java Vo Attribute Name
Ex: PlanId is the Java VO Attribute Name for the Database Column PLAN_ID
In The Same way Hw We Get the Relation ship for All other columns In the Controller Cllass ..
Can Any One Reply as It is urgent Req...
Thanks ,,
Jithen

Instead of using the VO attribute names to set and get values, best to go to the VO definition, click on Java, and generate the View Row Class with the accessors.
In the class where you're trying to set attributes, instead of a Row class, use the View Row class of your VO (eg ViewObjectName's class would be ViewObjectNameRowImpl), and when retrieving a row from the VO, cast the row to the previously mentioned View Row Class.
At that point you can use the View Row Class's methods that would perform sets and gets of each column.
To get attribute names, I don't know off the top of my head, but there might be a method mentioned in the Javadoc for the ViewRowImpl or ViewObject or ViewObjectDefinition classes to get the attribute/column mapping, or perhaps you can somehow read the XML definition of the VO which has that mapping.
Assuming business components were built automatically and no attribute names were overridden, intuitively the attribute name is a camelcase version of the column name, removing understores and capitalizing the character following the removed underscore - but that's not a fool proof approach. Just a general observation.
Hope this helps.
