Request value in a query

Hi all!
I discovered a set of values I need in the WWV_FLOW_TABS table, and it's easy to get the result if I introduce a request value into my query.
For example, what I want to do is:
SELECT TAB_STEP
FROM FLOWS_030100.WWV_FLOW_TABS
WHERE TAB_NAME = 'the request value'
AND FLOW_ID = :APP_ID
How I can replace 'the request value' with the value of the request that i've just required? for ex. "T_customers", T_documents", etc.
Thanks a lot

Hello,
>> What I need and don't have, is a kind of 'APP_PAGE_NAME' variable substitution
I’m also not sure what you are trying to do, however if you need a ‘APP_PAGE_NAME’ substitution string, you can create your own. First define an application item by that name. On every page you need to use it, you can utilize its value, using a before header computation or process. Now you can use it with the ‘&APP_PAGE_NAME.’ notation, including in an item label field, and it will act as a regular substitution string.

Passing request value into a query

Hi,
I was wondering whether it was possible to pass a request value into a report query in apex 3.2.
I have a button with a submit value of "ALL" which when pressed i need to open up all the contents of a query as opposed to on those that have been completed.
SELECT *
FROM TABLE
WHERE (STATUS = 'COMPLETE' OR :REQUEST = 'ALL')
I was expecting this to return only completed records, unless the Button is pressed and then I want to return all records regardless of status.
Can someone please advise whether this will work? At present it does not seem to recognise the request.
Cheers,

Significance of request id found in query designer

hi all,
significance of request id found in query designer while creating an multi provider?
what does this request id hold. and what is it signifiance in Multi provider?
can anyone throw light on this.
regds
haritha

Hi Haritha,
That Request Id is nothing but request of dataload ( It is having date , Time,Number of records received & Number of record transferd.).
If u want the display data in query which is in datatarget upto Ur choosing request this is possible with this RequestId field.
By this Request Id u can display data for ur selected request ( Updated request).
Observe Request in Manage datatarget screen & Query Request ID values BOTH ARE SAME***.
Thanks,

.MSG files. Problem with getting requested values from crawled properites

Hi
I have a lot of msg files on my file server. I use SharePoint Enterprise Serach engine to crawl all these MSGs.
I would like to get extra managed properties out of these files. I am most interested in getting Mail:5(text) / Mail:12(Date and Time) / Mail:53(Date and Time) from MAIL category in Managed Properties.
This thread is very similar to one already posted by SpinnerUp:
http://social.technet.microsoft.com/Forums/sharepoint/en-US/82d69df0-5cb2-4e51-a485-34209e111f4b/problem-with-crawling-msg-files-doesnt-seem-to-return-requested-values-from-crawled-property
Please be aware that I do not use Public Folders. These MSGs are exproted from Outlook and are stored on File Server not Exchange.
I tried to link Crawled Properties to new property however I cannot get any results back.
Thank you for you help.
Regards, Marcin (Please mark as helpful or answered if it helps)

Thank you for your replay.
However I am not keen to write custom connector at this stage.
Is it possible to simply get "Subject", "Sent", "Received" info from msg file and then map it to managed properties.
Does SharePoint create any crawled properties which contain information about let's say "Subject" which then can be used to create managed properties?
I tried playing with "MAIL" properties however I cannot get them to work. I guess this is because the file is a msg file rather than mail which is stored in Exchange Public Folder.

CHAR's value in the query but not in the report??

Hi all,
I loaded master data and crm transaction data from ODS to Cube. The data is in the cube but there is no value in my report when running it. EX: there are some CHARs in my report, I checked those CHARs have value in the query but it shows 'not assign' in my report when I run it. What happen?
Thanks.
J.

Please see below text and also the sent link..
If a navigation attribute is used in an aggregate, this aggregate has to be adjusted using a change run as soon as new values are loaded for the navigation attribute (when master data for the characteristic belonging to the navigation attribute is loaded.) This change run is usually one of the processes that are critical to the system performance of a production BW system. This is why, by avoiding using navigation attributes or not using navigation attributes in aggregates, you can improve the performance of this process. On the other hand, not using navigation attributes in aggregates can lead to poor query response times. The data modeler needs to find the right balance.

Dynamically passing the values to IN query in JDBC

Hi,
I have a list which contains a single or multiple values which does have CustomerVO as a generic.Here i need to iterate the list pass these values to "IN" query.
These should happen dynamically, as we dont know whether the list will hold a single or multiple value. If the list.size ==1 , then it contains a single value in it. Hence there is no need for a comma(,) in the IN query else we need to have it, like .... IN (Aaron,Bob). Please help me in this?
Thanks.

Hence there is no need for a comma(,) in the IN query else we need to have it, like .... IN (Aaron,Bob).So basically you need to output the List (capital 'L') as a comma-delimited list (small 'l').
The procedure for that is usually something like:
1. Output the first element.
2. For any further elements:
2a. Output ","
2b. Output the element.

Large XML Publisher reports fail with client-error-request-value-too-long

We are running BI Publisher 5.6.3 with Oracle Applications 11.5.10.2 (ATG.H RUP 5), and are having frequent failures with client-error-request-value-too-long messages on large PDF reports that cause the entire report to not print.

Has anyone had this issue with BI Publisher on Linux?

Thanks for the link. It looks like the sysadmins have throttled cups to low to allow large bitmapped print jobs:
grep MaxRequestSize cupsd.conf
# MaxRequestSize: controls the maximum size of HTTP requests and print files.
MaxRequestSize 10M
I am trying to get a more reasonable size limit.

The linux sysadmins set the cups max_request_size at 10 MB, which was causing this error. Once the restriction was lifted, the reports ran without error.

Apply request values from a region on an event from another region

Hi,
I am quite new to ADF and that's my first question/post here (and as a matter of fact pretty much anywhere),
so i hope i manage to make my problem clear enough.
First i am using ADF Faces + ADF BC using JDeveloper 11.1.2.1.0 with the integrated WebLogic Server
Now the what is the case:
I have a page with two af:regions in it.
The first one is basically a single selection table.
The second one is a to put is simply an edit form for the selected row of the first table.
I don't use the contextual events mechanism ( i have spent some week or more playing around with it awhile ago, but from that exprience i don't recollect any particular thing that might solve my problem) so what i do is pass as parameter to the first(table) region a "delegate" that would listen/handle selection events and in the backing bean of the table i have the selection listener that fires the events/calls the delegate's handleEvent(String eventType,Object data) method so that the main page knows and refreshes the second/edit form region
with the newly selected ID of the entity.
My problem is that if i had entered data in the form in the second region it is lost after selection
has been made in the first one.
I see (in the http request content of the selection event, or in the requestMap), that all that was in the html page, including the second region is transmitted to the server - so are the newly entered values. However the jsf components that are a part of the second region are not applied with their new values, nor their model is updated in the next jsf phase.
Now I suspect that has something to do with the (Adf)RichRegion being a EventRoot or something.
I tried putting partialTrigger to the second region (though i currently and for various reasons call the AdfFacesContext.addPartialTarget programmatically at about one million places in the java code after the selection event)
I even tried hacking the javascript AdfRichRegion object, so that it would always return false if asked isEventRoot. :) that's how desperate i was
The only solution i have so far is:
First to make clear. When i say refreshing the second region i don't mean calling RichRegion.refresh(), but rather RichRegion.queueActionEventInRegion(....., "refresh",PhaseId.ANY_PHASE) which in the second's region taskflow is just a method call, that sets the right current row of the iterator and then loops back to the same (one and only view in this taskflow - the edit form) and adds some parialTargets to the AdfFacesContext, so we see the new data
then in that methodCall (which i think happens in the INVOKE_APPLICATION phase) i add those few lines to make sure the values are applied to the jsf components sub-tree of interest:
RichPanelGroupLayout fl = getFl();//that's a binding of the UIComponent, that holds all the inputTexts i care about
fl.processDecodes(FacesContext.getCurrentInstance());
fl.processValidators(FacesContext.getCurrentInstance());
And when i say make sure that the values are applied... i actually mean - get on my knees and pray because the whole thing looks too hacky already, but so far it works.
But now i have to make sure the validation has been ok (otherwise i get a funny effect of seeing the red popups at the invalid text inputs just for a second and then my region is refreshed to the new entity or i get an JBO exception depending of whether i call the next lines that follow without the if(..){processUpdates}
How do i check this:
System.out.println(FacesContext.getCurrentInstance().isValidationFailed());
//The above line would print false nomatter what happenned so i decided to use this "something":
boolean validationFailed = FacesContext.getCurrentInstance().getMessageList().size()>0;
if(validationFailed){
//dont update the iterator's current row and return to the edit form page
return "fail";
}else{
fl.processUpdates(FacesContext.getCurrentInstance());
//update the current row and return to the edit form page
It took me days to come up with this...i would call it hack...And a day or two more to adapt the rest of the page's logic with the whole design changes i had to make but i still believe there must be some better solution that i am missing because for a number of reasons i don't feel right eith this one, which, while implemented and working (i hope) makes the whole real case a lot more complex than it used to be (and still feels like a hack),
just for the simple reason that I want to get some updated values back in the model.
Just as an example of a design change i had to make i give you the afformentioned methodCall i had to add, because the processUpdate would not work if not called with the right adf bindings context... first i tried calling them from a custom PhaseListener i have but at that moment nobody knows what #{bindings.MyEntityId.inputValue} is.
Thanks and Greeting

Oh yes... and i have also noticed that if the action is triggered from a component(e.g. clicking on a commandLink) that is a part of the main page
the values are updated in all regions (i think so :) ) ... so i even tried a client listener in the first region that calls javascript function that queues a custom event with a source component from the main page, but yet the selection event is propagated to the server even with the event.cancel() and evt.stopBubbling()
and i could not make my custom event force the apply request values... but here i might have done somthing wrong i dont know it is a mess anyway... sure this one sound more of a hack than my current option....by my criteria at least

How to use 'REQUEST' value on PL/SQL

Hi All,
I have assigned 'SEARCH' as button request to search button. I want to use this value in PL/SQL some thing like
IF REQUEST='SEARCH' THEN

--do something else
END IF;
Can any one suggest how to access the 'REQUEST' value?
Thanks in advance.

Hi rchalton!
Sorry for that. Here is an english document which also shows an example of how to use v('REQUEST') or :REQUEST.

How to use Item value in chart query

Hi Folks,
I am looking to use calander item value in sql query used to populate flash chart. I tried with following query where P2_DATE1 is the calander item name. This says no data found. I am not sure if I am missing some thing with BUTTON settings which I am using to put data into chart.
Select null "link",to_date(entry_date,'dd-mon-yy hh:mi:ss') "Time in GMT", to_number(load_avg_5,'99.99') "Load Avg 5 Min" from oracle_ocm.top_load_avg --where trunc(entry_date)=:P2_DATE1
I am new to APEX
Please help

Here are few things for you to try:
Hardcode the value and see if it works. "where trunc(entry_date) = to_date('01-May-2010', 'dd-Mon-yyyy')". If it works, then click Session link at the bottom of the page, and check the value of the item P2_DATE1. If null, then you have a problem. If not null, please ensure that you use TO_DATE function as shown above with proper format mask.
Good luck.

How to get the max value in the query??

    From the above values , how can i findout Max(Soldout.Qty)(i.e 20) for the above week...Suppose present aggregation = summation...How can i findout the value in the Query??don't want to do changes to design...

Hi Bhanu,
I tried the calculation results as...Maximum,..
But that will pick the maximum value among the avialable values..like
plant1 max 10
plant2 max 20
plant3 max 30
then it will show as..
plant1 max 30
plant2 max 30
...like this...but my case is
plant1 calday1 10
plant1 calday2 05
plan1 calday7 08
plant2 calday1 10
plant2 calday2 05
plan2 calday7 20
so for each set it need to bring the maximum value...

Client-error-request-value-too-long

What is this error???? I am trying to add an Epson 1280 printer and I get this error. I have the most current driver and not sure why this isn't working.

My flatmate had this "client-error-request-value-too-long" problem with her (powerpc) powerbook. Nearly everything I tried didn't work:
1) Reinstalling drivers
2) Permissions repair
3) Resetting print system using Fixamac's Printer Setup Repair Utility
4) Updating from 10.4.10 to 10.4.11
5) Using the command line to try and recreate the directory: /var/spool/cups/tmp (which told me it already existed)
6) Using Transmit (with show invisible files turned on) to browse to /var/spool/cups/ and try and recreate the tmp folder
On the last point I couldn't change anything about the /var/spool/cups/ directory because the permissions were corrupted in some way. It keep telling me tmp already existed but I couldn't see it.
In the end what did work was enabling and logging in as root, browsing to /var/spool/ using Transmit and deleting the cups folder and then recreating. It took a few tries to delete too, but in the end I managed to remove it.
Of course I wouldn't actually recommend this. I'm no Unix geek so god knows what I might have broken in the process, so I'm going to reinstall her system with the Archive and Install options when I get a chance, which is what I'd recommend doing in the first place to anyone having this problem.

Error: "client-error-request-value-too-long" when trying to add printer

After installing the 10.4.9 Combo update, my HP 1350 All-in-One printer was not recognized. I reinstalled the driver, but now I can't add the printer. I get the error message "client-error-request-value-too-long" when trying to add the printer. Has anyone else experienced a similar problem.
Thanks in advance

Well, I tried all of that and I'm still getting the error message. I've also repaired disk permissions and run Disk Warrior. When I repaired disk permissions, many HP printer items showed up in the list.
