Possible to display null item value as 'All' in blank HTML region?

Apex 4.1
Theme 21
Hi There,
I have select list which has null and other values. I have created a blank HTML region with the following text
Report for the year &P2_YEAR. and for geography &P2_GEOG.
Now P2_YEAR works fine because, it is always populated with a year. However, &P2_GEOG has 'All' as null value since we can see the report for all geographies. However, if the all option is selected, the above &P2_GEOG. shows as null. Since its not a PL/SQL proc, I cannot put in a NVL. I am guessing one possible way is to write a PL/SQL code before region and then check if its null and then try to populate a new hidden field and show, something like that. Wondering if there is a way to do it directly in the HTML region?
Thanks,
Sun

Hi Morten,
in the validation callback you could use apex_util.set_session_state to modify the page items value. We do that ourself in the "Number Field" native item type plug-in.

How do you display an item value based on other items?

Item C's value depends on item A and B. If both A&B are null then C should display null , if A is null but B is not null then display 'Ok', everthing else display ' problem';
3 items on page 5
item A: name p5_A, display as text (saves state). source type is a dabase column
item B: name P5_B, display as text (saves state). source type is a databbase column
item C: name P5_C, display as text (based on PLsql doest not save state), source type pl/sql anonymous block ? like the following
if :P5_A is null and :P5_B is null then :P5_C is null; else if :P5_A is null and :P5_B is not null then :P5_C := 'OK'; else :P5_C := 'Problem'; end if;
Can someone tell me what did I do wrong on these stements unde apex? Thanks a bunch.

Alternatively, you could do a add a computation for that item - same source as mentioned in the previous reply, but each will work.
Also, in your anonymous block, you have:
if :P5_A is null and :P5_B is null then :P5_C is null; else if :P5_A is null and :P5_B is not null then :P5_C := 'OK'; else :P5_C := 'Problem'; end if;should probably be
if :P5_A is null and :P5_B is null then :P5_C := null; elsif :P5_A is null and :P5_B is not null then :P5_C := 'OK'; else :P5_C := 'Problem'; end if;so instead of :P5_C is null , assign it a null - :P5_C := null. Also, else if in pl/sql is written as: elsif

Display Distinct Item Value

Hello All,
I am having an problem displaying a distinct value for Item 'PK_EMPL_ID'. I need all the Items below because I am passing these values to another page in APEX. But I need help with this select statement syntax.
SELECT hs.pk_session_id,
       hsp.pk_session_process_id,
       hs.fk_class_id,
       hsm.pk_empl_id,
       hsm.last_name || ', ' || hsm.first_name studentname,
       dg.department_group_descr,
       pd.department_descr,
       hsm.fk_dept_group,
       hsm.fk_dept_code,
       hsp.fk_empl_id,
       hs.session_meridiem,
       hsn.session_name,
       hs.session_date,
       hsp.session_process_status
    FROM   hrt_session hs,
           hrt_session_name hsn,
           hrt_session_process hsp,
           hrt_student_master hsm,
           cobr.department_group dg,
           cobr.pps_department pd
    WHERE hsn.pk_session_name_id = hs.fk_session_name_id
       AND hsp.fk_session_id = hs.pk_session_id
       AND hsp.fk_empl_id = hsm.pk_empl_id
       AND hsm.fk_dept_group = dg.pk_department_group_id
       AND hsm.fk_dept_code = pd.pk_department_idMy output is like:
-PK_EMPL_ID-
JOHN
JOHN
JOHN
BOBBY
JAMES
I only want to display each 'PK_EMPL_ID' value once when the select statement is executed, not duplicate values. I have tried distinct, group by etc... but I am having trouble since I am using multiple tables using these foreign keys. I have viewed a few threads but they are only handling one or two item values from one table. Can anyone assist me with please? Thanks ahead of time.

Hi,
Whenever you have a question, post a little sample data (CREATE TABLE and INSERT statements) for all tables, and the results uyou want from that data.
You may have a clear idea of where you're coming from, and where you want to go, but the description alone doesn't convey that clear idea to us.
You can also rephrase your question in terms of some commonly available table, like scott.emp.
For example: "I'm doing this query on scott.emp:
{code}
SELECT      job
,     deptno
FROM     scott.emp
{code}
How can I get only 1 row per distinct job?"
Without sample output, the question is still vague.
There are 14 rows in scott.emp.
You can reduce the output to 9 rows by changing "SELECT" to "SELECT *DISTINCT* ":
SELECT DISTINCT
     job
,     deptno
FROM     scott.emp
;which produces:
OB           DEPTNO
MANAGER           20
PRESIDENT         10
CLERK             10
SALESMAN          30
ANALYST           20
MANAGER           30
MANAGER           10
CLERK             30
CLERK             20But that's as far as you can go without changing the results.
For example, all three departments have MANAGERs. If you want only 5 rows of outptu (one for each of the 5 distinct jobs), then which deptno do you want?
If you want the lowest one, here's one way to do that:
WITH     got_rnum     AS
     SELECT     job
     ,     deptno
     ,     ROW_NUMBER () OVER ( PARTITION BY job
                               ORDER BY         deptno
                       ) AS rnum
     FROM    scott.emp
SELECT     job
,     deptno
FROM     got_rnum
WHERE     rnum     = 1
;Output:
JOB           DEPTNO
ANALYST           20
CLERK             10
MANAGER           10
PRESIDENT         10
SALESMAN          30There are other apprioaches to this problem, too. The advantage of this one is that it works well with any number of columns in the output.

Do not display NULL tables/values(Urgent)

Hi,
My template consists of a parent BC and child BC fields(BIP integrated with Siebel) . I have inserted the child table inside the parent table. When there are no values in the child record i do not want the parent record to get displayed. I tried giving a condition <?if:ActivityStatus!=''?> in the child. The child table does not get displayed if there are null values but the corresponding parent record gets displayed. I tried constraining in the parent also but of no use. Any kind of help is greatly appreciated.Thanks in advance.

Using unbounded item value for rendering expression in a region

Hi there,
I use jheadstart 11g tp2.
I have a question about a group in application definition module which all of the items are unbounded.
For 3 of them I use text input lov which related to lov that is bounded to a view.
I use the return value of the lov for filling unbounded items and I want to use that filled unbounded item for rendering expression of a region.
my problem is after using lov I can't use the binding value of the unbound item (which filled by returning value from lov) for another part of the the group
I have a region that should be visible and invisible based on that item
Please let me know is there anyway for doing this or not?
Thanks for your help
Setareh Rajaei

the unbound item has a variable binding in the page def, so you can refer to the value of the unbound item using the expression
#{bindings.[groupName][itemName].inputValue}

Grouping to display null values for all the missing dates

Hi SAP,
I am trying to display '0.00' value for all the missing dates in my crystal reports as follows:
17-Jan-14     40.00
18-Jan-14       0.00
19-Jan-14       0.00
20-Jan-14     80.00
However, my crystal report is showing as follows:
17-Jan-14     40.00
18-Jan-14       0.00
19-Jan-14
20-Jan-14     80.00
The missing dates with no data are group together and my '0.00' value is not. Kindly advise me the solution. The formula is shown as per attached.
Thank you.
Regards.

Hi,
Thanks for your reply.
Fyi, I am using a formula field in crystal report to display "0.00" for days in between as follows:
whileprintingrecords;
if Days_Between({Command.DocDate},next({Command.DocDate}),'dd-MMM-yy') = "" then "" else "0.00"
There is another formula field in crystal report to display the missing dates in between as follows:
whileprintingrecords;
Days_Between({Command.DocDate},next({Command.DocDate}),'dd-MMM-yy')
Below is my report custom functions:
Function Days_Between (datefield as datetime, nextdatefield as datetime, format as string)
' This function is only used to display what data is missing within a specified date range...output type is text
dim thisdate as date
dim nextdate as date
dim output as string 'output is the text display
dim daysbetween as number
dim looptimes as number
looptimes = 0
daysbetween = 0
output = ""
thisdate = datevalue(datefield) + 1
nextdate = datevalue(nextdatefield)
if nextdate - thisdate > 1 then daysbetween = nextdate - thisdate else daysbetween = 1
do
if nextdate - thisdate > 1 _
then output = output + totext(thisdate, format) + chr(10) _
else _
if nextdate - thisdate > 0 _
then output = output + totext(thisdate, format)
looptimes = looptimes + 1
thisdate = thisdate + 1
loop until looptimes = daysbetween
    Days_Between = output
End Function
The issue arise when when there is more than one missing dates in between but the null values ("0.00") displayed is only for the first missing dates and not for all the missing dates.

How to send a list item value to URL to open data related to item value

Hi,
Iam using Apex4.0 and iam facing some problem. Iam unable to send selected list item value to the url specified in the HTMl region.
Here i want to open the data related to list item value in other page.
List item - :Familyp
i want to pass this selected value to the url and when ever user selected the list item and clicks on the url, then it should display the item value related data in new page.
I tried with &FamilyP in url but it's not working. Any one help me plz.
Regards
Vamsi.Tata

Is it a normal Select list or Multi Select list?
If you have select list that allows you to select multiple options then you cannot pass it through URL. Multi-select /Shuttle keep colon separated list in the item, and this confuses Apex because the Apex URL uses colons for a different purpose. No escaping or URL encoding will help.
If it is normal select list that allows selection of only one option then you can pass through the url. Unless of course the data has a colon in it.
For multi-select, and when the value contains colon, the only way is to save the value in session state, same page item or any other place like Application Item, and then reference it at the other end. Never pass through the URL.

Display Dataset field Value in the footer based on the Group

Hi Guys,
My current SSRS report is displaying multiple projects data. One Project data is rendering into 1 or 2 pages based on the project specific data.
Now, the requirement here is to display the "ProjectName" in the footer of the SSRS report in below format. For instance, if project A data is rendering in 2 pages then the footer in two pages should display project Name A and in the
third page it shows display the Project Name b in the footer of the report.
ProjectName [Insert Reporting Month] Page
# of #
Has anyone come across such requirement. Thanks.
Warm Regards Badal Ratra

Hi Badal,
In SQL Server Reporting Services (SSRS), we cannot use the “Project” filed without specifying a dataset aggregate in page footer. However, we can display the item value in the page footer. Please refer to the following steps:
Add a list in the report. Configure this list with the corresponding dataset.
Configure the list “Group on:” ProjectName.
Add the tablix in the list, add page break “Between each instance of a group” of the list.
Add a text box (TextBox1) with expression below:
=Fields!ProjectName.Valu
Set the visibility of the text box to Hide.
Add a text box in the page footer fill with following expression:
=ReportItems!TextBox1.Value
If you have any questions, please feel free to let me know.

PAGE RADIO BUTTONS and APPLICATION ITEM VALUE

I have several pages that use same radio button group that permits filtering the report query (of course on each page, it is a page level radio button item).
I created an application item value to hold the last used value of a radio button item.
On login, I would like the application item value set to a default value.
For a given page using the recurring radio button group item,
I would like the radio button item value set to the application item value on entry into a page.
I would like the report to use the application item value on entry to a page.
I would like the application item value be updated anytime the page level radio button item value is changed, so that when you move to another page,
the next radio button group and report can use the last selected radio group button value.
I am trying to use a variety of solutions in COMPUTATION and CONDITIONAL COMPUTATION... to include use of set_session_state procedure, and I am not getting desired result, partial success, but not complete.
Can you have a computation item that is only for initialization of the report and radio button group on page entry?
And a separate computation item that senses user selection of another radio button, updating the report, and updating the application level item?
Help requested. Thank you.
Would be nice to have application level objects, like radio button groups.

Created Page 0
Created an HTML region in COLUMN 2 and SEQUENCE 10.
Selected under region CONDITION:
Current Page is contained within Expression 1 as comma delimited list of pages
in the EXPRESSION 1 provided the requested comma delimited list of pages that I wished the HTML region to appear.
Created the radio button group item P0_RADIO and assigned to Page0 HTML region.
Selected under item CONDITION:
Current Page is contained within Expression 1 as comma delimited list of pages
in the EXPRESSION 1 provided the requested comma delimited list of pages that I wished theradio button group to appear.
In SHARED COMPONENTS I created an APPLICATION COMPUTATION
In the computation I created a PL/SQL function to initialize the radio group
BEGIN
IF :P0_RADIO IS NULL THEN
RETURN 'A_ALL';
ELSE
RETURN :P0_RADIO;
END IF;
END;
'A_ALL' being the default value for :P0_RADIO
Radio group appears on the desired pages, is initialized to the desired default value, and works properly on each page.

How to display the value of a javascript variable in a html region ?

Hello,
I need to display my page title or name in a html region.
I added a script in the <title> section of the template header... :
(thanks Andy : Get page name from page attributes ?
<script type="text/javascript">
var pageTitle = '#TITLE#';
</script>... so I can use it in a javascript variable.
But now I don't know how to display it in a html syntax..
Thanks!
Fanny

... so I can use it in a javascript variable.Don't see any reason to modify page templates to introduce an unnecessary global JS variable when the document property is already there. Display it using an appropriate HTML element, e.g <tt>h1</tt> if it's the overall page heading.
<h1>
<script type="text/javascript">
document.write(document.title);
</script>
</h1>

Display word/pdf document in the HTML region or report

Hi,
How to display blob content stored in a table in HTML region or report region.
I already have a process to display the image content.
But my question here is how to display word/pdf document within the html region so that the user can read the document without downloading it.
Any suggestions/solutions would be of great help.
Thanks in advance...
Thanks,
Ramesh P.

I was dead wrong.
The display of images from BLOB is a special case because APEX provides a Display Image item type.
Moreover, HTP/HTF packages also do not provide for handling of BLOB content. So AJAX cannot be used.
Which implies that the only way to get binary content, other than images, is with the use of a WPG_DOCLOAD.DOWNLOAD_FILE call.
This in turn implies that it may not be feasible to "inject" the BLOB into an exist HTML DOM in the Browser.

Conditionally display items based on null LOV value

Hello,
I've seen several examples that do what I'd like to do but with different implementations. Perhaps someone can steer me in the right direction...
I have a pop-up lov that pulls a list of names from various places. If, however, the name cannot be found I'd like to display a few text boxes where the user can enter a new name.
For my list of values I have configured the following:
Display Null: Yes
Null Return Value: -1
Null Display Value: Not Found
My HTML Form Element Attributes has: onchange="doSubmit()";
My Source section has:
Source Used: Only when current value in session state is null
Source Type: Static Assignment (value equals source attribute)
My entry text boxes have a condition specified:
Value of Item In Expression1 = Expression 2
Expression 1: P4_LOOKUP_NAME
Expression 2: -1
I also have an unconditional branch to this same page (Page 4) that sets the value of P4_LOOKUP_NAME to P4_LOOKUP_NAME.
I cannot seem to get this item to display though...any thoughts?
Thanks in advance for your suggestions!

jhammer,
I like the concept. This would require a custom popup lov - something that can be a little tricky/time consuming the first time around. The popup lov would probably have to create new entries via Ajax to be able to pass back the correct ID/display values to the parent window on close.

Dan
