Dynamic assignation of :new in a trigger

Hi,
I have some generic code that I put in all my triggers to get the value of the next ID (Primary Key) in a table.
I would like to use dynamic SQL to set a :NEW value.
Something like :
:new.||v_id_col_name := 12345;
where v_id_col_name is the name of the column.
Is there a way that I can do such a thing ?
Thanks
Francis.

> I would like to use dynamic SQL to set a :NEW value.
Not possible to treat the :NEW bind variable as a dynamic variable. References to this variable must be "hard coded" - you cannot treat it dynamically.
There is however a work-around that allows some flexibility in treating :NEW in a dynamic fashion - using the Object_Value() function. This however requires the table to be an object-relational table.
I've posted sample code in [url http://forums.oracle.com/forums/thread.jspa?messageID=1543770#1543770]this thread illustrating this approach.

Dynamically displaying a new region (row?) based on immediate user input

Whew, figuring out a title was almost as hard as trying to explain what I want to do!
Okay, a little background first.
My app has 178 main data fields, spread across about 35 tables. The users want to be able to search any and all data fields. So, I wrote a PL/SQL package that for each master record, loops through all of the child tables and creates (more or less) an XML file for each master record (which I store in a CLOB field). When any data in any table is changed, a trigger fires to re-update that CLOB field as well. I then used Oracle Text to create an index on the CLOB field, and now the users can search across all of the available information for each master record and get a list of which records contained what they were looking for.
So here's the first part of the problem. The app is a Mineral Occurence database for all mineral information world-wide. Say they enter "Brazil" as what they want to search for, they not only retreive all of the mineral sites in Brazil, but also all of the sites where one of the mining companies may be based in Brazil, or Brazil is one of the comments, etc. While this is the expected behaviour, it's still not quite what they expected (but they also don't want to get rid of this behaviour either).
So, since the CLOB field is already formatted with XML-type tags, what I want to do is to have an Advanced Search page, where the user can specify the table name to search, or the field name, or both. What I'd like to do is at the end of each line, have a select list with an "AND" or "OR' box, and if that gets a value, then dynamically create another 'row' underneath the first row, with the same three 'boxes' (actually select lists), and continue on until the user has specified exactly what they want to search for.
I would rather not have to create a whole bunch of regions or rows, and then determine at runtime whether or not to display them.
So i would have (using underscores as the boxes/fields):
Table to Search Field to Search And/Or
______________ _____________ _______Each of the above would be a select list.
Anybody have ideas on how I can accomplish this? Any Javascript or AJAX-type solutions that a dummy like me can easily implement? I've seen something almost similar on Carl's example pages to Hide/Show a region(?), but understanding the underlying code and then modifying it for what I want to do is extremely complicated (for me) at best.
Thanks.
Bill Ferguson

Well, after searching through the QBE results (even some of mine), the only thing that comes close is Earl's (http://htmldb.oracle.com/pls/otn/f?p=36337:14). Actually his layout is almost perfect and pretty identical to what I want/need. Vikas' example seems like what I've toyed with on some other pages in my app, using a simple UNION ALL with nulled fields in the select statement, which won't work for what I need, at least I can't seem to visualize how I could incorporate that same code logic.
However, unlike Earl's, when/if the last column (which I'd have as the 'AND/OR' select list) is populated, I'd like to dynamically display another new row.
Now I know I could do it by making the last column a 'Select List With Submit', but that would neccessitate my creating about 25 regions (to hopefully cover the max any of the users would ever need), and then conditionally display the region based on whether or not the previous 'AND/OR' condition field was populated. It would also require a whole slew of page refreshes, which is clunky.
It seems like there should probably be a way with AJAX to accomplish something similar. I think I remember seeing something along these lines in the last year or so on here, but I can't find it.
Something like a cross-breed of Earl's example page above mixed with Carl's example at http://htmldb.oracle.com/pls/otn/f?p=11933:39:4740898821262791902::NO:RP:: which would automatically fire on the poplulation of the last select list is probably the best I can accomplish, unless somebody has some better ideas on how to do this. Using Carl's htmldb_remix code, I can avoid all the submits and the resulting page refreshes, but the code itself will take an old dummy like me a while to figure out.
Thanks for the ideas though.

From which verison of oracle support the :NEW variable in trigger

A trigger using the :NEW variable can be compiled in oralce 10g but can't in oracle7 .
Does oracle 7 support the :NEW variable?

>

You can answer questions like this yourself by always checking the documentation first.
NEW is not a variable, it is a correlation name.
See 'The Trigger Body' section in the Oracle7 Server Application Developer's Guide
http://docs.oracle.com/cd/A57673_01/DOC/server/doc/ADG73/ch9.htm
>
The Trigger Body
The trigger body is a PL/SQL block that can include SQL and PL/SQL statements. These statements are executed if the triggering statement is issued and the trigger restriction (if included) evaluates to TRUE. The trigger body for row triggers has some special constructs that can be included in the code of the PL/SQL block: correlation names and the REFERENCING option, and the conditional predicates INSERTING, DELETING, and UPDATING.
Accessing Column Values in Row Triggers
Within a trigger body of a row trigger, the PL/SQL code and SQL statements have access to the old and new column values of the current row affected by the triggering statement. Two correlation names exist for every column of the table being modified: one for the old column value and one for the new column value. Depending on the type of triggering statement, certain correlation names might not have any meaning.
A trigger fired by an INSERT statement has meaningful access to new column values only. Because the row is being created by the INSERT, the old values are null.
A trigger fired by an UPDATE statement has access to both old and new column values for both BEFORE and AFTER row triggers.
A trigger fired by a DELETE statement has meaningful access to old column values only. Because the row will no longer exist after the row is deleted, the new values are null.
The new column values are referenced using the NEW qualifier before the column name, while the old column values are referenced using the OLD qualifier before the column name. For example, if the triggering statement is associated with the EMP table (with the columns SAL, COMM, etc.), you can include statements in the trigger body similar to
IF :new.sal > 10000 . . .
IF :new.sal < :old.sal . . .
Old and new values are available in both BEFORE and AFTER row triggers. A NEW column value can be assigned in a BEFORE row trigger, but not in an AFTER row trigger (because the triggering statement takes effect before an AFTER row trigger is fired). If a BEFORE row trigger changes the value of NEW.COLUMN, an AFTER row trigger fired by the same statement sees the change assigned by the BEFORE row trigger.
Correlation names can also be used in the Boolean expression of a WHEN clause. A colon must precede the OLD and NEW qualifiers when they are used in a trigger's body, but a colon is not allowed when using the qualifiers in the WHEN clause or the REFERENCING option.
The REFERENCING Option

GP: Dynamically assignment of users

Hello,
i'm a newbie and i have the following question:
Can i dynamically assign the user of the next step in a guided procedure?
The initiator of my GP passes some data to a web service. The web service determines on the basis of the data the user of the next step in my GP. Is this possible? And how can i achieve this scenario?
Thanks in advance and best regard,
Matthias

Hi Matthias,
Unfortunately, the GP external service callable object only works for RFCs. You cannot use it for a Web Service.
Therefore, I would propose the following solution. You can import a Web Service as an external service in CAF (using the Composite Application Services perspective in the Developer Studio). Then you can use the external service from a CAF application service. The application service can already be exposed as a callable object, and you can take the user ID as an output. Then you can use the predefined callable object Assign Users to Process Role, and map the application service output to its input. To enable the assignment of the relevant user to the next action, you must consolidate the role created for the Assign Users action to the role created for the next action, and set the type of the new role to Runtime Defined. Then, at runtime the Assign Users object is executed in the background and the user is assigned to execute the next action.
You can find how-to guides describing how to import a Web Service in CAF and how to integrate it further into CAF in the https://www.sdn.sap.com/irj/sdn/developerareas/platform?rid=/webcontent/uuid/d8dbd703-0801-0010-c9bf-c04bc52f562f">caf [original link is broken] [original link is broken] (see tutorial N.81).
Hope this helps a bit.

Dynamic Assignment

Hi all,
I have created a BPEL process, using User Task Activity, via Sequential Workflow Pattern.
I have used the wizard as desired and at assignment policy i have chosen to use "dynamic assignment using xpath expression". Although this seems like dynamic assignment it pushes me to choose even if the assignees will be users or groups. What I need here is to assign task to both users and groups together a mixture of both. when i look from BPEL process manager Audit Tab I should be observing (element of <RoutingVar1>)
<approvers>groups("Aaa"),user("Mmm"),users("bbb")</approvers>
how can manipulate "setRoutingPolicy" Assign activity.
I am a new bee with XPath expression.
Thanks for all.

Your question is a bit difficult to understand. Please elaborate.

Dynamically assigning variable in xml loop

I am trying to dynamically assign a variable name so I can
build an accordian nav from and XML doc. the code looks like this:
ACnav['depthChild0']._alpha = 0;
ACnav.setStyle("color", 0x0ffffff);
ACnav.setStyle ("openEasing",
mx.transitions.easing.strong.easeout);
ACnav.setStyle ("selectionDuration",
mx.transitions.duration.slow);
navXML = new XML();
navXML.ignoreWhite = true;
navXML.load("menu1.xml");
oY=5;
var currentSection = 0;
function buildNav () {
DisposableXML = new XML();
TempXML = new XML();
button = new Array();
//buttonNum = new Array();
subitem = new Array();
menuItem = new Array();
o = new Array ();
subitemlocation = new Array();
DisposableList = new Array();
buttonList = navXML.firstChild.childNodes;
i = 0;
sectionLength = buttonList.length;
while (i<=buttonList.length) {
if (buttonList
.nodeName.toLowerCase() == "button") {
DisposableXML = buttonList;
DisposableList = DisposableXML.childNodes;
buttonName = buttonList
.attributes.name;
set ("buttonNum", "buttonNumber"+i);
trace(buttonNum);
ii = 0;
//trace(buttonName+"-"+buttonNum);
//ACnav.createChild("View", buttonNum, {label: buttonName,
icon: "mainNav"});
button = ACnav.createChild("View", buttonNum, {label:
buttonName, icon: "mainNav"});
oY=5
while (ii<=DisposableList.length) {
TempXML = DisposableList[ii];
if (DisposableList[ii].nodeName.toLowerCase() == "subitem")
subitem = TempXML.attributes.name;
//subitemlocation = TempXML.attributes.location;
subitemNum="subitemNum"+[ii]+
//trace(buttonNum+"-"+subitemNum+"-"+subitem);
menuItem = ACnav.buttonNum.createChild("subNav",
subitemNum, {childText: subitem});
menuItem
.move(0, oY);
oY=(oY+25);
//trace(buttonNum);
ii = Number(ii)+1;
i = Number(i)+1;
//trace(button);
trace(menuItem);
redraw();
//gotoAndPlay('reload');
The problem lies with this line: button =
ACnav.createChild("View", buttonNum, {label: buttonName, icon:
"mainNav"});
If I quote the "buttonNum", it works, but jumbles the subnav
items together vs in the proper node. I need to have that declared
dynamically so that each parent node has a differentID and then
createchild goes under that. Anyway, I've tried alot of stuff over
the last few days and its getting frustrating.
Thanks for the help if anyone contributes!

You shouldn't need to do a concat within the XQuery path parameter. Try the following:
bpws:getVariableData('inputVariable','payload','/ns1:Request/ns1:instance[bpws:getVariableData("j")]')

Dynamically Assigning Users

Hi,
I am trying to dynamically assign users within my process and need some guidance with it. The following two steps briefly describe what I am trying to achieve
1. A user starts the process by filling in data into the PDF and completes the task.
2. Based on the information filled in by the first user, I have to determine who the user for the next task is going to be and then assign the task to the user accordingly.
I do not have the option of using multiple assign task operations and then setting the logic within the route evaluation, as there are way too many users that can be assigned for the second task ( there are more the 50 possible users from which the second user has to be selected )
I am fairly new to Livecycle and from the options that I have seen so far, here are few questions that I need some help with
1. The only option within the Assign Task operation that lets you assign the user dynamically is by using an XPath expression. If I were to use this, should I be embedding the logic within the form itself and then use the XPath expression to find the user by dynamically updating the form after the first user completes the task?
2. Is there another approach to achieve this other than having the logic for selecting the user defined in the form itself? I believe embedding the logic in the form might not be a good idea as it can have performance implications and also having user information in the form itself doesnt seem right.
3. Is there an operation that I could use, which would contain the logic that I would need to determine the next user and then assign the task to the user based on the result of the operation?
I am hoping someone would have definitely run into this situation before so any suggestions/thoughts will be appreciated.
Thanks,
Varma

"1. The only option within the Assign Task operation that lets you assign the user dynamically is by using an XPath expression."
Yes
"If I were to use this, should I be embedding the logic within the form itself and then use the XPath expression to find the user by dynamically updating the form after the first user completes the task?"
I depends. If you can get to it server side, it woulb probably better. If you need to make a change to something, you don't want to change the form.
"Is there another approach to achieve this other than having the logic for selecting the user defined in the form itself?"
I'm not sure where the logic for the next user is located, but you could make a database or web service call from the process to get the next user instead.
"I believe embedding the logic in the form might not be a good idea as it can have performance implications and also having user information in the form itself doesn't seem right."
I agree.
"Is there an operation that I could use, which would contain the logic that I would need to determine the next user and then assign the task to the user based on the result of the operation?"
Again, I need a bit more info as to where the info (logic) is located.

How do I assign a new Apple ID to iPhoto?

It all began back in 2010 when I bought a used PowerMac G5 to see how I got along with MacOS. When I got it, the OS was already set up, along with a few Apps, such as iPhoto and iMovie. I didn't have an apple ID back then, and it didn't matter, because the OS running (Leopard) didn't require one. So I used the preinstalled iPhoto.
Then, in 2011, i scraped my money together, bought a MacBook Pro and used the built-in Mirgation assistant to get my documents and data there.
Since then I wasn't able to update iPhoto, because it probably was installed on the PowerMac with a different apple ID - and this information was transported over to my Macbook. The app store wouldn't let me install it with my own ID. And because I can't find a dmg for iPhoto, I can't just uninstall and reinstall it.
Now using a non-updated iPhoto wasn't really a problem - until now that Mavericks won't support this old version any more. And I can't access my photos any more.
So is there a way to assign a new Apple ID to iPhoto? Or to uninstall and reinstall it without losing any photos?
Because there is no way to get the ID from the company that sold me this Power Mac. I don't have any contact data any more...

To create a new ID see:
Frequently Asked Questions About Apple ID
Then either you can:
- erase the iPod (Settings>General>Reset>Erase all Content and Settings) and set it up as a new iPod with her ID
- Use the new ID on her iPod but only for:
Settings>Messages>Send and Receive
Settings>FaceTime
Settings>Game Center
and Settings>iCloud if you want her to have separate Contacts Calendar and some other things.
You can also continue to use the same/common Apple ID for Settings>iTunes and App stores so you can share purchases.

Hi Vikranth,
I am displaying one ALV list say with columns A and B.
I have value in A but not in B. Now at runtime user selects one row, clicks on push button in application toolbar, then i have to display value in column B in the already displayed list.
I searched and came to know it can be done with oops concept. but i am not using classes and methods.
so how can i do this?

Webutil crashes while calling Function in when-new-item-instance-trigger

Hello !
I use Oracle AS 10.1.2 and webutil 1.0.6 and Oracle Forms Developer Version 10.1.2.
When I call the webutilfunctions within a when-button-pressed or post-change trigger, everything works fine.
When I call the webutilfunctions within a when-new-item-instance-trigger i get an error message:
oracle.forms.webutil.file.FileFunctions bean not found.
CLIENT_TEXT_IO.fopen will not work
What are the reasons for this behavior ? How can I solve the problem ?
PLEASE HELP !!!!!!!!

I think that this is well explained in the webutil documentation(pdf).
You cannot use the functions in the initialisation phase of the form, including triggers like When-New-Form-Instance, When-New-Block-Instance,etc...
The workaround is to use a timer to wait the necessary time for the beans to instantiate themselves.

When-new-form-Instance trigger raised unhandled exception ORA-04062

Hi,
We are facing ORA-04062 (FRM-40735 WHEN-NEW-FORM-INSTANCE trigger raised unhandled exception ORA 04062) while trying to run the first form of our Application.
We are using a PL/SQL LIBRARY(.pll) for forms.
We are using 10G Application Server,10G DB and Oracle 9i Forms.
DB Version----10.1.0.4.0
Application Server--9.0.4.0
During compilation, we are following the below steps:
1. Compile the .pll
2.Compile Forms.
When we are running these compiled version of forms and pll in Development server where we are compiling it,we are not facing any error.
But when we are taking these compiled version of forms and pll to the Production Server,we are getting the above error.
When we are compiling the .pll in Production server, Application runs fine.
But we should not compile form or pll in Production server.
Searching in Metalink(Note:73506.1) , we find a solution that remote_dependency_mode if set to signature this problem may be resolved.
We tried that by chaning ' REMOTE_DEPENDENCIES_MODE=SIGNATURE' in Init.ora file in both Production and Development server.
But the error still persist.
I think the problem is regarding .pll.Because for the time being to test the application,I compiled the pll in Production and we didnot get any error while running the Application.
But whenever we are tring to deploy the compiled version of pll (compiling in Development sever) and to run the application in Production, we are facing the error.
Also, pll calls one standard database package in SYS.That standard package has VALID status both in Production and in Development.
We donot have priviledge to change/compile that package.So,we didnot change anything in that package. We didnot change anything in .pll also.
We are upgrading our forms from 6i to 9i.And now when we are trying to deploy it to Production we are facing ORA-04062 error.
Can anyone please help ?

Exactly what procedure or package in SYS are you calling that causes this problem?
Are both test and production databases at the same version?
Do you know what procedure or package is named in the error? If not, then you need to improve your on-error trigger processing. I use a PLL_On_Error trigger to capture and improve a number of Oracle messages. It is posted here:
 Re: FRM-40735:Pre_Insert trigger raised unhandled exception ORA-20011
Note especially the part near the end that deals with FRM-40735. (Not sure, but you may also want to display DBMS_ERROR_TEXT in your situation.)
If that doesn't help find the actual problem, I would pull out my Re: Zdebug -- Download a Forms debugging message tool, and add messages before every call in the when-new-form-instance process to zero-in on the offending call.
If it really IS a call to a system process, I would then experiment with creating a server-side package or stored procedure that calls the process, and then call that stored procedure from my form. That way, you effectively insulate your form from system differences.

WHEN-NEW-FORM-INSTANCE trigger does not fire

Hi,
Does anyone have any idea why code placed in the when-new-form-instance trigger appears to be ignored when the form is executed from one login but runs fine when executed from another? A breakpoint on the first executable line of code in the trigger confirms that the trigger is not being fired.
Regards,
Ian Dodds.

Hi again Duncan,
I was able to solve it once I ran the form with the Forms Runtime Diagnostics enabled. I had a table in my schema containing old data used to build menu items. This was causing runtime errors to occur during calls to SET_MENU_ITEM_PROPERTY that were not being propagated to the UI so I didn't know they were occuring.
The upshot was that the WHEN-NEW-FORM-INSTANCE trigger was not firing. Once I corrected the data it worked a treat.
Thanks very much for pointing me towards FRD, it's the first time I've used it but it won't be the last.
Cheers,
Ian.

Populate two poplist items on when-new-form-instance trigger

Hello!
I have a simple form with some text-items, datetime items, two poplist items and two buttons (exit and save to database).
Everything works well except the second poplist wont get populated. After wrote the code for the first i just wrote a similar one for the second poplist. Each poplist fetches its data from different tables. Nothing changed when i tried different list-item types (first worked, second didnt).
Here is the code in the when-new-form-instance trigger:
declare
     rg_query_sponsori varchar2(200) := 'select nume, sponsor_id from sponsori';
     rg_id_sponsori recordgroup;
     err_sponsori NUMBER:= 0;
rg_query_portari varchar2(200) := 'select nume, portar_id from portari';
     rg_id_portari recordgroup;
     err_portari NUMBER:= 0;
BEGIN
     rg_id_sponsori := create_group_from_query('recgrp1',rg_query_sponsori);
     err_sponsori := populate_group(rg_id_sponsori);
     clear_list('vizitatori.sponsor_id');
     populate_list('vizitatori.sponsor_id',rg_id_sponsori);
     rg_id_portari := create_group_from_query('recgrp2',rg_query_portari);
     err_portari := populate_group(rg_id_portari);
     clear_list('vizitatori.portar_id');
     populate_list('vizitatori.portar_id',rg_id_portari);
END;
Thx and have a nice weekend :)

Try this by adding delete_group
declare
rg_query_sponsori varchar2(200) := 'select nume, sponsor_id from sponsori';
rg_id_sponsori recordgroup;
err_sponsori NUMBER:= 0;
rg_query_portari varchar2(200) := 'select nume, portar_id from portari';
rg_id_portari recordgroup;
err_portari NUMBER:= 0;
BEGIN
rg_id_sponsori := Find_Group('recgrp1');
if not id_null(rg_id_sponsori) then
delete_group('recgrp1');
end if;
rg_id_sponsori := create_group_from_query('recgrp1',rg_query_sponsori);
err_sponsori := populate_group(rg_id_sponsori);
clear_list('vizitatori.sponsor_id');
populate_list('vizitatori.sponsor_id',rg_id_sponsori);
