Max Date in Page item

Has anyone figured out how to get a date field to default to max date when used as a page item. I have select max(timestamp), create an item timetwo that -= max(timestamp), you name it we have abused and used it. Nothing seems to work.. I am sure we are missing the obvious. Any help appreciated.

Reset data picker page item by selection page item in Apex

Hi,
Need to create a report based on date ranges and for this created a interactive report and two page item datepicker fields P15_fromdate and p15_todate. Report works fine with this criteria.But user wants one more field quarter(P15_quarter), When they select the quarter the range values has to get reset and as to get applied to report.
Issue here is unable to find a way to set the page range item values based on the quarter field selection
Need help how to reset the page item fields.
Thanks in advance.
Thanks,
Sandeep

Ligon,
You're right to think this is pretty laborious stuff. A co-worker wanted to do the same, to make sure users didn't lose a change when clicking Cancel. I suggested he look at calculating the query checksum before and after, which he tried. But it got very cumbersome very fast and he ended up dropping the idea. He's fairly new with Apex, but he's also a quick study, so it's not like he's a novice coder.
I don't have his implementation details anymore to even share with you.
Sorry I couldn't be more help.
Good luck,
Stew

Bug: Null Element Width and Max Width on page item won't stay null (v3.0.1)

Well, it's pretty much what it says. I'm trying to edit a page item and remove the width and max width on the Element properties. When I remove them and hit apply it functions properly, and the page item shows up with no width or max width property set. However, if I go to edit the page item again, the Width and Max Width fields are populated (30 and 2000 respectively) again. Thus, any action which saves the item will save the unwanted values. I don't want a width and a max width on the item; it shouldn't put them back.

I think default values should only be used in a
situation where no value has previously been
provided.
How can I tell the difference between the case where
I fetch a null value from the column because a null
value was previously saved and the case where "no
value has previously been provided"?Well, I would assume that there is something unique about the initial creation of an item versus the editing thereof (e.g. the item does not exist in the database, yet). It's only on create that you would want to provide default values, that is, when no value has previously been provided by the user. Any other time the item is edited, it already exists and any values submitted should not be overridden or replaced. Off the top of my head, this could be done with table level defaults (if all item types were to share the same defaults for all properties), or via an insert trigger. Either way, the defaults would only be applied on create, and not on edit.

Date Ranges: Page Items or 'Input Parameters'?

Hi,
What is the best way to implement an user input date range qualifier in worksheets?
So far I've only been able to achieve this by using item classes on a date field. Very messy.
Anyone else doing this?

Thanks Gveeden.
How do you setup your date parameters?
Are they 'conditions'? If so, how do you let the Users specify values in User Edition?
Hope you can help out.
Thanks already,
Peter Verhoeven.

Arangement of Page Items and Regions

I created an APEX page (version 4.0.1.00.03) named Request Edit with many page items for data entry of user requests. The form has a region named Request Edit that holds the data entry page items. Within the region is a region for buttons. There were two addition regions on the page below the buttons named Jobs a report region and Audit a Show/Hide region. The users do not like to scroll the page during data entry so I decided to place many page items into three new Hide/Show regions name Requestor, Recipient, and Service. I defined the regions and then moved the page items to one of the three regions Requestor, Recipient, and Service. When the page is displayed the three new regions displayed after the audit region. I wanted the new regions to display after the Request Number and before the Comments page items. I decide to change the Parent Region in the User Interface properties of the page to Request Edit for the new regions. That moved the three regions above the Audit region but after the Comments page item.
What properties of the three new regions Requestor, Recipient, and Service will position the new regions after the Request Number and before the Comments Page items? Is it necessary to define the Parent Region in the User Interface properties of the page to Request Edit for all of the regions?
To describe visually what I am trying to do imagine the following simplified page:
<Create> <Save>
Request ID: [________]
Requestor Name: [_________]
Recipient Name:[ __________]
Service Type: [____________]
Comments: [____________________]
<Create> <Save>
Jobs Report Region
+Audit Region
I defined three regions and moved the page items to them
<Create> <Save>
Request ID: [________]
Comments: [____________________]
<Create> <Save>
+Requestor
+Recipient
+Service
Jobs Report Region
+Audit Region
After I defined the Parent Region in the User Interface properties of the page to Request Edit it looks something like this:
<Create> <Save>
Request ID: [________]
Comments: [____________________]
+Requestor
+Recipient
+Service
<Create> <Save>
Jobs Report Region
+Audit Region
But I want the new regions to display between the Request ID and Comments page items.
Thank you.

here is how i got someting like that to work with a raoid group.
page HTML header:
<script>
function Show_On_Radio_Value_2(pThis, pThat, pValue, pLabel){
var rv = html_RadioValue(pThis);
var elm = document.getElementById(pThat);
var lbl = document.getElementById(pLabel);
if (rv == pValue) {
html_ShowElement(pThat);
html_ShowElement(pLabel);
} else {
html_HideElement(pThat);
html_HideElement(pLabel); }
}</script>
REGION Footer:
<script>
Show_On_Radio_Value_2('<code>P3_ENT_APPROVAL</code>
','<code>P3_REJECTION_DESC</code>
',"Y",'L_<code>P3_REJECTION_DESC</code>
</script>
I think thats it but it should get you in ther right direction.

Refresh only page item while submitting data from the popup window

Hi All,
I'm pretty new to Apex .....
I have a form with text items as first few entries and then a radio button list and few text items again. On selecting certain radio button I have a popup window which acts as an interface for the next text item in the calling page. The purpose of having the popup window is that the text item following the radio button takes the input with certain character delimiters along with the data. Instead of using delimiters while entering the data I want a meaningful data to be keyed in the popup window and all the string operation to be done as a background process. I have been successful this far. I'm using the below javascript on click of the submit button.
javascript:doSubmit();
window.opener.doSubmit('REFRESH');
window.close();
On doing this I'm losing the values submitted for the items prior to the radio button(including radio button). Please note, I have a dynamic action set on page load to reset the values. Is it possible to refresh just the page item from the popup window.
Also, I tried excluding the window.opener.doSubmit('REFRESH'); from the above javascript. It sets the item with the expected value (viewed it in the session items, however I would like to view the concatenated string on my calling page) but following this there is an insert operation which uses all the necessary items in the form. All values except the value returned from the popup window is populated into the table. Am I missing something.
Any help in this regard is appreciated.
Thank you!!!
Regards,
Ganesh

Value set using Javascript is only in your browser page but is not yet available in the session. This is why the report doesn't return the expected output.
Before refreshing the report you would need to set the session state of this item.
You can set it after you assign the item a new value or before the report is refreshed
For Interactive Reports, this is available built in
you can go to Report Attributes >Advanced Attributes -> Page Items to Submit and specify P2_X1 for the field(and any other page item that the report is dependent on)
For standard reports, you can create a Dynamic Action that is triggered "before refresh" of the report's region, and choose PLSQL as the action types, give a dummy BEGIN NULL END; for the code and specify this item name in the page item to submit field so that it sets the items's value in session.

How to pass the page item data from tabA to TabB of a discoverer report

I have a discoverer repoort, it is master_detail (Dept-Emp) report
TabA is a master worksheet, which has a page item Deptno
(the data is from a customized query)
TabB is detail report which has a Deptno as the page item
which show the emp detail info on this deptno
(the date is from another customized query).
What I want to do is;
When I change the Deptno in TabA, TabB should automatically change to the deptno of Tab A when I click TabB.
How can I pass the page item deptno from TabA to page item of TabB?
Thanks for your help

Hi.
You are absolutely right, you cannot create a link from Page Item.
My Idea was (and I'm sorry taht I didn't mention it at the beginning) to create one link for each and every column in the report in the TabA.
All these links would be exactly same and pass the Deptno to the TabB.
So the end user can click wherever he wants (all cells on the worksheets have the link to the TabB) and he is always redirected to the TabB with the Department parameter seted to Deptno Page Item from TabA.
As I already said before, it is not exactly what you expected, but it's probably the best you can get out of Plus.

Page Item with Date format DD-MON-RR - APEX 32

Hello,
I am passing date parameter but somehow it is not formatting date properly on calendars.
For e.g.
Below is my calendar query
select distinct count(*) knt, initcap(username) username, to_date(to_char(trunc(timestamp),'DD-MON-RR'),'DD-MON-RR') ts from xrx_master_records
group by initcap(username), trunc(timestamp)In above query TS is the date column that results in DD-MON-RR format.
Then I format column on calendar tab as shown below, here is how I am constructing the link.
But the issue is - #TS# field shows complete date with time stamp for page item P40_DAILY_DATE. i.e. instead of 21-JUL-10, it shows 21-JUL-2010 12:00:00 AM. That means, it is ignoring calendar query and reads straight from database.
How can I make sure that P40_DAILY_DATE item receives date in DD-MON-RR format?
Then, I plan to use P40_DAILY_DATE to connect with the report region by comparing timestamp column from same table with P40_DAILY_DATE.
Please advice.
Thanks,
R

Viewer slow while retrieving data while changing value from a page item

Hi, I am using 9.0.2 to create reports. My end-users are using Viewer to run these reports. Recently, we are experiencing performance problems with Viewer. We have reports with Page Item. Let say a report takes 1 min to run. After running the report if a different value is selected for a page item, it is takes another 1 min to get new data. Whereas, Desktop is not taking any additional time (noticable) for a different value for the page item. Recently, we are experiencing this problem. I thought that it was cache problem in Application server, so we restarted all the pieces in aps server. However, the problem still exists. We are using a materialized for this particular report.
Any tips would be highly appreciated. Thanks.

The performance differences can be attributed to the differences in product. Desktop is a client server product. A query executes and ALL data is returned to the desktop. You can manipulate that data in any way and the database is not required. Web (Plus/Viewer) only return the data needed to satisfy the query currently being viewed. If you change a page item, a database call is made to retreive additional/different data.
In other words this is just how things work. You can alter settings in your prefs.txt file to improve performance in Viewer/Plus. Changing number of rows returned, memory settings, row fetch limits, rows per fetch all can improve/reduce performance.
As best I know there is not a "magic" setting for these values. It is based on the server/volume of data/workbook content/ workbook layout. etc. Crosstab workbooks are much slower to return data than page -detail.

Random page item data corruption

I designed an APEX page for a service request processing application with several date page items. Our database is Oracle 10g. The application is in production and the users have reported that data in some date page items become corrupted randomly. For example, the user enters ’07/04/2011’ in the date page item “Planned Start Date” among other values and submits the page. The date somehow winds up ‘07/04/0011’ that is, year 11. (A corrupt date increases the risk that these transactions will not be processed in a timely manner and will negatively impact the level of customer service the user wishes to provide.)
I have identified three possible areas that may hold the key to underlying cause: 1) page item edit mask, 2) page process(es), 3) DB column constraints. Inasmuch as this is a random problem and has affected a handful of rows it may not be possible to trace the logic as the pages are processed. Has anyone encountered this problem and can suggest a possible remedy? For the sake of clarity I placed the setups for the affected page item below.
Selected setups for P14_PLANNED_START_DATE, all unlisted attributes are blank or null:
Settings - Value Required: No; Format Mask: MM/DD/YYYY; Show: on icon click; Show Other Months: No; Navigation List for: None
Source - Source Used: Always, replacing any existing value in session state; Source Type: Database Column; Maintain Session State: Per session; Source Value or Expression: PLANNED_START_DATE
Default - Default Value: to_char(sysdate, ‘MM/DD/YYYY’); Default Value Type: PL/SQL Expression
Sample page processes are:
Validation - Name: P14_PLANNED_START_DATE not null; Type: Item specified is not null; Validation expression: P14_PLANNED_START_DATE; Always execute: No
Conditions – Condition Type: SQL Expression; Expression 1: :REQUEST IN (‘SAVE’, ‘CREATE’)
Validation – Name: P14_PLANNED_STARTEND_OKAY; Type: Function Returning Boolean:
Validation Expression:
IF SIGN(to_date(to_char(to_date(:P14_PLANNED_START_DATE,'MM/DD/YYYY'),'YYYYMMDD-') || :P14_PLANNED_END_TIME,'YYYYMMDD-HH:MI AM')
- to_date(to_char(to_date(:P14_PLANNED_START_DATE,'MM/DD/YYYY'),'YYYYMMDD-') || :P14_PLANNED_START_TIME,'YYYYMMDD-HH:MI AM')) > 0
THEN RETURN TRUE;
ELSE
RETURN FALSE;
END IF;
Conditions – Condition Type: PL/SQL Function body returning Boolean
Expression 1:
IF :REQUEST IN ('SAVE','CREATE') THEN
IF (:P14_PLANNED_START_TIME IS NULL OR :P14_PLANNED_END_TIME IS NULL)
THEN RETURN FALSE;
ELSE RETURN TRUE;
END IF;
ELSE RETURN FALSE;
END IF;
Database: The attributes for the database column are
Column Name: PLANNED_START_DATE

Page item (date picker)

I have added a date picker to my report . and in the report source I've added a where clause to filter the report as per the selected date(which is one of the columns in the table) but there is nothing shown.
where DATE =:P23_DATE
when I remove the where clause all the records appear and when I return it ..nothing there.
can someone help me?
Edited by: Beena-IT on May 4, 2013 7:19 AM

You have data, that's good. You've isolated the problem to what seems to be the WHERE clause, good. The WHERE clause is simple, good. So, it would seem DATE NOT = :P23_DATE for your query.
Remember -- or note, if you didn't know this -- page items are (always?, mostly) character strings. As Jeff intimates, if DATE is a date, you will get implicit date conversion in your WHERE clause. (BTW, isn't DATE a Reserved Word?) May I suggest trying "DATE = TO_DATE(:P23_DATE,'your date format here')" to make it an explicit conversion?
Also, I recommend running any query you are having a problem with in the APEX SQL Commands window. Then you can immediately see what APEX is returning for your query. It helps my debugging a lot.

Howard

Selected page item has no data

1) After I create the new data model, and start the EP_LOAD_MAIN how can I see the sales history table in the colaborator workbench? I only see the hierarchy of levels ,and in the right of the page, I have the message "Selected page item has no data" and an empty graphic background. Is there something with the Analytical Engine?
2) There are several errors in the Engine Administrator after i start it:

Hi DCRO,
1) After I create the new data model, and start the EP_LOAD_MAIN how can I see the sales history table in the colaborator workbench? I only see the hierarchy of levels ,and in the right of the page, I have the message "Selected page item has no data" and an empty graphic background. Is there something with the Analytical Engine?
I am assuming that before starting EP_LOAD_MAIN, data is present in the staging tables (T_SRC_XXX). So once EP LoAD MAIN completes data should be available in Items, Location and Sales_data tables. Then whenever you try viewing data on the worksheet through the collaborator Workbench (Contains links of the worksheets) based on the aggregation levels(item,location and time) selected in the worksheet definition, the data is displayed on the right side of the worksheet.So in your case, check for the levels and the members under the levels that have been selected in the worksheet. Analytical engine is for generation of forecast (either by Batch / Simulation / Other profiles) and has got nothing to do with the empty graphical background of the worksheet.
2) There are several errors in the Engine Administrator after i start it:
08:59:51:234 ERROR INSERT INTO SQL_DEF (COMMENTT, LINE_NO, SQL_ID, SQL_TEXT) VALUES ('Aggri Level 201',1,201,'SELECT min(sales_date) datett, round(NVL (sum(#quantity#),sum(#fore#))')
08:59:51:234 ERROR - ErrorDescription: ORA-00001: unique constraint (DEMANTRA.SQLD_PK) violated
In the PL/SQL developer the SQLD_PK doesn't exist
The error message itself points to some Constraint violation in the procedure. Check the procedures that have errors after the rebuilding of Data model. Recompile them and then try running the Engine Administrator.
Also, I would suggest you to go through the Oracle Discussion Forums FAQ so that your queries are answered effectively and efficiently.
Thanks and regards,
Shekhar

How do you populate a page item in apex with a value read from excel

Dear All
I am working on application where I am uploading a csv file in oracle apex. I then need to access a value in Cell B2 of the csv file and populate a page item called
:P2100_AUTHORISATION_ID with this value. Many of the examples I have found upload the data using v_data-array into a table but I don't need to do that I just need to get the value from the csv file and then display additional information about the file allowing the user to either or continue or cancel the request to upload. I am running into a small problem that I can't explain and wondered if anyone had any ideas.
Here is the code I am using to try and populate and item called :P2100_AUTHORISATION_ID but when I poulate the item the value is always 0. But if I replace the line :P2100_AUTHORISATION_ID:= v_data_array(2) with a raise_application_error(-20001,v_data_array(2)); The correct value is displayed in the eror. Any Help would be appreciate and I apologise in advance if this akes no sense at all:-)

Hi Joel
Continuing on from my last question, there was something else I want to ask if you dont mind.
Now that I have the v_data_array(2) value in a page item I would like to use as an input value to a procedure to return some information I need displayed on the page. To do this I need to convert it to a number but when I try to so this I get the following error
ORA-06502: PL/SQL: numeric or value error: character to number conversion error
When I use the wwv_flow.debug that you told me about it is outputting a value '4851 ' so it look like there may be some sort of asii character causing a problem. I have tried using trim(v_data_array(2)) and ascii(v_data_array(2)) but nothing seems to work.
Would you know how to convert a v_data_array value to a number? At the moment I am attemting to do it withiin the same code I attached in my earlier post but I have replaced the assignment of :P2100_AUTHORISATION_ID with the code below where P_BL_WD_DATA_ENTRY.getauthid is the procedure returning the values I need.
:P2100_AUTHORISATION_ID:= P_BL_WD_DATA_ENTRY.getauthid(to_number(v_data_array(2)));
Thanks

Max Date Function

Hi,
I have the following columns in a report:
Vendor Name
Trade date
Prod Desc
Order Type
Qty
Gross Amt
I need to display only those rows where trade date = max(trade date).
I am aware of the MAX analytic function, but it keeps giving me an error.
Could someone please let me know how to achieve this scenario.
Thanks.

Hi
As pupppethead mentioned, it doesn't look as though you need a PARTITION BY clause.
A straight MAX(Trade Date) OVER () = Trade Date should suffice. The OVER() tells Discoverer to look at all dates in the query. You will only need a PARTITION BY if you are using Page Items or Group Sorts and you wanted a different date in each set.
By the way, as a word of warning, be very careful not to name items in folders or workbooks using Oracle reserved words. Naming an item as Desc is dangerous because that is the name of the descending switch in an ORDER BY clause of an analytic function. Thus, if you have for example something called ITEM DESC and try to do this:
RANK() OVER(ORDER BY ITEM DESC) you will have serious problems because the database (not Discoverer) will think you want to sort ITEM descending. Either ITEM does not exist and you will get an error or it does exist and you will end up with the sort on the wrong item.
Imagine also if you named something ORDER BY and then place this in a PARTITION BY clause like this:
MAX(Trade Date) OVER (PARTITION BY ORDER BY)
Interesting conundrum, don't you think?
Best wishes
Michael
