Help with Select Lists

Hello, Oracle community. I'm a new developer fresh out of school and I'm working on an issue tracker project on Apex 2.1. I have a page where we create cases that involve various issues called in by our clients through our support center. This app is supposed to replace what the support center currently has.
My main problem is functionality. I have several select lists that redirect to the case creation page. I have conditions that allow several hidden fields to appear when certain values are chosen. We also have a couple of text areas for details and resolutions. The problem is that when we enter data into the text areas (CASE_DETAIL and CASE_RES) and escalate the case to a higher tier of support via redirecting select list, all text that was typed is cleared away when it redirects back to the page. All other select list values remain because they've already been redirected. How do I keep my text fields populated while preserving my select lists? The text areas are set to "Only when current..."
If there's any links that you guys can provide with detailed info on how to handle these types or problems (the documentation is a bit general) I'd greatly appreciate it. I'm still learning this stuff. :)
Dennis

Wow, thanks.
We had tried this before, but since we had email shooting off to our clients whenever the page was submitted, we went with the redirect. My brother (we're both working on this project) found the following topic while looking for this one:
Select list with Redirect => other page items are reseted
We had used the process to only send email when the CREATE button was pressed but completely missed the fact that we could do the same with the process row. The solution now is to switch all select lists to submit and make the process row conditional to only fire when the CREATE button is pressed. Now the page submits as much as it wants to, the text fields stay populated, and we don't get redundant emails and entries into the CASE table.
Thanks for the help. I hope to return the favor some day. :)

Help with select list item and dynamics action

G'Day Apex Gurus,
I having problems trying to achieve to trigger the help window of a select item automatically. A help window is triggered when the select item label is clicked but my client would like to be triguered automatically as soon as the user click to see the options in the select list.
I think that I should be able to do it with dynamic actions but I can not get it to work.
I know when someone click on the label of the select list item trigger this JavaScript
javascript:popupFieldHelp('277938589795252851','1545903379570909')
So I want to trigger the javascript also when the user click of the select list item and pull down the options and for that I think that Dynamic actions is the way to go but I can't get it right.
This is what I a doing:
I created a Dynamic option as follow:
Name : test
Sequence: 30
Even: Click
Selection type: Item(s)
Item(s): P1_RATING <- a selection list item
Condtion: - No Condition -
True Actions
Sequence: 10
Action : Execute JavaScript Code
Fire when event result is :True
Fire on page load: ticked
Code: javascript:popupFieldHelp('277938589795252851','1545903379570909')
I appreciate any one who can tell me what i am doing wrong here or provide a solution to my problem of achieving to trigger the help window of a select item automatically.
Kind regards
Carlos

Hi Carlos,
I set up a test case in exactly the same way and it worked fine for me. I created a page item called P1_DA_DEMO and added some static select list values then added some help text. The settings I used are below, I suggest you try again but also make sure you have no other Javascript errors on the page. Use a tool like firebug to check.

Help with Select Lists in Classic Report

Hello,
I working with APEX 4.1. Oracle 11.
I have a simple classic report with 4 columns (Username, Role, Read, Update). The Read and Update columns are Select Lists with values of "Yes", "No".
Report looks like this:
Username Role Read Update
JSmith Admin Yes Yes
LJones Dev Yes No
My requirement, is that when a user selects Yes from the Update select list, the value of the associated Read column needs to change to Yes as well for that particular Username. The change has to occur upon selection of Yes from the Update select list.
Im not very strong with javascript, but for testing purposes I applied: onchange="alert('hi');" on the Update column. When I make a change to the Update select list, the alert does pop up.
Can anyone suggest how I can implement the change to the associated Read value of Yes if the Update value chosen is Yes, for that particular row.
Thank you,
Laura

The complexity in this case is that you're using items in a report rather than standard page items.

OnChanger="get_ajax_select_xml(this);" with select list (query named LOV)

Hello,
i used Vikas'example Re: cascading lov for tabular form
i have a problem with Select list (query based LOV)
when run tabular form i have the following error:
report error:
ORA-06502: PL/SQL: numeric or value error: character string buffer too small
the number of rows of the Lov are 900
the display variable is 70 char
is there any limit?
Thank in advance
Costanti

Leo,
Thanks for the response, but I don't think you quite understand my problem. If I go to the Column Attributes screen for the group_id field, I have the "Display As" drop down set to "Select List (query based LOV)", not "Select List (named LOV)". This requires that the sql query be written in the "List of values definition" text area below. Within that text area I have the following query:
SELECT DISPLAY_NAME, GROUP_ID
FROM APPLICATION_GROUPS
WHERE APP_ID = ?????
ORDER BY 1
The APP_ID that I need to reference is for the current row of data that is being processed. Therefore, I can't use a :PNNN_APP_ID variable, because that field does not exist on the page.
Hopefully this explains it a little better.
Thanks,
Kris

Help with SELECT - selecting range of numbers

Hi,
I need a help with SELECT statement. I want to select Dates starting from today and ending 30 days back. So the result would be like:
TRUNC(SYSDATE)
TRUNC(SYSDATE) - 1
TRUNC(SYSDATE) - 2
TRUNC(SYSDATE) - 3
TRUNC(SYSDATE) - 30I was thinking to simply select truncated SYSDATE in first column, and in second column numbers 0, 1, 2, ... 30. Then I would simply do a difference first column - second column. But how to select such sequence of numbers? I don't want to select each number (date) in separate select statement and then unioning them.
Does anybody have an idea?

Help with Multiselect List Item

Assuming one employee can work for multiple departments, I want to display the departments employee 7844 works for preselected in a multiselect list.
I am using the following query statement in a report region.
select htmldb_item.select_list_from_query_xl(1, deptno ,'select DEPTNO,DNAME from scott.dept ','MULTIPLE HEIGHT=25', 'Y',null,null,null,'Department',null) a from scott.emp where empno = 7844
The result I am seeing is a multiple multiselect lists with one department selected in each list.
How should I modify the query to get what I want?

Trying to use Spry with Select List

I have a dataset that is static xml. .In the xml file I have
a node called categoreis and then repeating node of store name,
phone and address in that category. There are around 15 categories
and a total of 100 stores with address and phone. I can create the
select list and add the onchange event to tell Spry which row of
data was selected in the drop down. I do not understand how to
generate the detail region that shows the stores for that
particular category. Any help would be appreciated.

Always include the following information when asking a question:

Report -- filter with selection list -- show all values after select page

Hello!
I have the following problem:
- I have a report
- this report can be filtered with a selection-list
- the selection list is based on dynamic LOV and has a null-value
- I added the code of the report the following, to filter the report after choosing a value of the selection list:
... and (instr(type, decode(:P8_FILTER_type, '%null%',type,:P8_FILTER_type)) > 0)
This works very well.
But my problem is: When the user logs out and the next time, he logs in, the selection list shows " --- show all values --- " (my null-display-value) and the report is empty "no values found".
---> I want to show the first time, the page is selected ALL the values of the report. (this is now only possile if I press the button which belongs to the selection list)
I hope, somebody understands my problem.
Thank you so much,
LISA

Hello Lisa,
The first time it's probably NULL.
So what you can do in your where: (instr(type, decode(NVL(:P8_FILTER_type,'%null%'), '%null%',type,:P8_FILTER_type)) > 0)
Off topic: I also wonder if that where clause can't be simpler? Do you rely need the instr?

Report with select list and link to call another report

Hi,
I am trying to do 2 reports (REPORT1 and REPORT2).
The first is a summary report (REPORT1).
This report will display sales figures for the year. Now, I need to have a select list in the result set that will have 2 options, depending on which option is chosen, I want to call REPORT2 with the select list as a parameter. How can I do this ?
Let me try to explain what I did.
I created REPORT1 on Page 100
SELECT YEAR, sum(YTD_SALES), APEX_ITEM.SELECT_LIST(1,'DEPARTMENT','Department;DEPARTMENT,Division;DIVISION') Drilldown FROM SALES_ANALYSIS WHERE YEAR > 2000
GROUP BY YEAR ORDER BY YEAR
I created 2 hidden items namely P100_YEAR and P100_DRILLDOWN
I also made the column YEAR as a link and specified both P100_YEAR and P100_DRILLDOWN as parameters to be passed.
Next, I created REPORT2
SELECT YEAR, DECODE(:P100_DRILLDOWN, 'Department', department, 'Division', Division) dept_div, sum(YTD_SALES) ytd_sales
FROM SALES_ANALYSIS
WHERE YEAR = :P100_YEAR
When I run Report 1, it's fine, when I choose either Department or Division from the Select List and click on the link to call Report 2, report 2 is displayed, but the value being passed for P100_DRILLDOWN is not correct and as a result, I am unable to get correct results for Report 2
Am I missing something ? Are there any alternate ways to do what I'm doing ?
Thanks,
Ashok

Hi Ashok,
The link definition will not know the value selected in the list as it is constructed only when the page is being rendered. You would need to create some javascript to handle this. I've done that here: [http://apex.oracle.com/pls/otn/f?p=267:182]
The link on the EMPNO column has been defined in the HTML Expression setting for the column instead of the Link section. The HTML Expression that I have used is:
<a href="#" onclick="javascript:doDrilldown('#EMPNO#',this);">#EMPNO#</a>And, in the page's HTML Header setting, I have added in:
<script type="text/javascript">
function doDrilldown(empno,group)
var g;
var p = group.parentNode;
while (p.tagName != "TR")
p = p.parentNode;
var x = p.getElementsByTagName("SELECT");
if (x.length > 0)
g = x[0].value;
var url = "f?p=&APP_ID.:183:&SESSION.::::P183_EMPNO,P183_GROUP:" + empno + "," + g;
document.location.href = url;
</script>When a link is clicked, the doDrilldown function is called passing in the EMPNO value and the "this" object (which identifies the object triggering the call). The function starts from that object and goes up in the HTML tag tree to the nearest TR tag (the row tag that the link is on) and then finds the first SELECT list item on the row and gets its value. It then constructs a URL using this and the EMPNO value and performs a redirect to the second page (page 183 in this example).

Need help with select that month range with flexible first date

Hello everyone,
I am trying to create a selection of month range (will be in a WITH clause) for a report to display monthly data. But the first month start date can be any date. (Not necessarily the first date of the month)
Examples:
Report input parameters:
Start Date: 08/10/12
End Month: Dec 2012
I was trying to build a with select that will list
Month_Start, Month_End
08/10/12, 31/10/12
01/11/12, 30/11/12
01/12/12, 31/12/12
OR
Month_Start, Next_Month
08/10/12, 01/11/12
01/11/12, 01/12/12
01/12/12, 01/01/13
End month is optional, so if no value the select will list only
08/10/12, 01/11/12

If you want to generate a Counter Table containing the integers 1 througn x in SQL, you could say
SELECT ROWNUM AS n
FROM    all_objects
WHERE   ROWNUM <= x
;but, starting in Oracle 9.1, it's much faster to say
SELECT LEVEL   AS n
FROM    dual    -- or any table containing exactly 1 row
CONNECT BY LEVEL <= x
;Also, x can be greater than the number of rows in all_objects.

Tabular form with select list not updating

I have created a tabular form with a dynamic select list
select primary_key, column1,
htmldb_item.select_list_from_query(10,column2, 'select descr d, column_value r from lookup_table where column_value = '||column1) column2
from main_table
The select list appears to work correctly but the new value is not saved to the database. I assume this is because the tabular form element display as field for column2 is set to "standard report column" but when I select any of the "display as text" or "LOV" options either the current data is not displayed or errors are generated.
Any suggestions?
Thanks,
Bob

Hi Ian,
As you have seen, sorting on the project_manager_id column will sort by the id value rather than the textual value. This is, of course, because this is the value in the field.
I haven't tried this out, but one thing that may work is the fact that you don't have to include the ORDER BY fields within the SELECT statement. You could, for example, do:
select p.project_number, p.project_manager_id
from projects p, users u
where p.project_manager_id = u.id (+)
order by u.name
Obviously, you won't be able to do this in the existing statement as you would then be blocked from using column sorting. However, it implies that if you could construct the SQL statement dynamically, appending appropriate ORDER BY strings to the end of the base select statement, you could sort by anything you like. This does, of course, mean that you would have to create a mechanism to allow the user to select the sort order, generate the appropriate string and reconstruct the entire sql statement.
I had had a similar request quite a while ago. The underlying reason for that request turned out to be that the user just wanted to quickly locate records relating to one person. In the end, we agreed that a search filter was the best thing to do.
Regards
Andy

RE-FX: Dev with selection list

Dear all,
We have in the RE-FX module a development which creates a printout using a smartform.
We first had the development without the selection list: you enter a range of invoices & every invoice gets printed.
We added the selection list functionality (where the user can select the documents he wants to print). Now the printing continues (after selecting the documents) with the standard printing functionality: creating a PDF printout instead of our developed smartform.
Does anybody know which customizing, enhancement, change to development, ... has to be done to be able to print out the smartform instead of the original PDF form?
Many thanks!
Best regards.

Help with selecting chuncks of data from a table

Hi all,
I need help with a query that should do the following.
I have a table with vessel messages, and I need to get the last "NumMsgs" messages from a group of vessels.
The problem I have is that if I order the table by Vessel_ID, MessageDate DESC, I can´t do ROWNUM < NumMsgs (<-- Then number of messages to be shown is a user parameter)
I know it should be something like:
select * from (
select *
from Messages m
where TRIM(m.V_ID) = '11597' /* I was trying for a single vessel atm */
order by m.V_ID, m.MESSAGEDATE desc
where rownum < :NumMsgs

Interactive Report with Select List LOV's

Hi All -
I need to develop an Interactive Report which displays reports based on values selected from a select list (LOV's) on this IR report.
Following is what I am working on.
This page has 2 select lists with the corresponding LOV values:
Date From ==> Q1, 2010
Q2, 2010
Q3, 2010
Q4, 2010
Date To ==> Q1, 2010
Q2, 2010
Q3, 2010
Q4, 2010
When the user visits this report page first time, "Date From" and "Date To" select lists have null values and the report should display all the records.
Once the user selects values from "Date From" and "Date To" select lists then the report should be filtered based on the values selected i.e.
If the user selects *"Date From"* ==> Q1, 2010 and *"Date To"* ==> Q3, 2010, then the report should show all the records whose reporting period falls between "Jan 1, 2010" to "Sept 30, 2010" i.e Q1-Q3 2010 only.
And the Reporting date format stored in the table is "18-OCT-2010", "12-APR-2010" etc ....
How can this be achieved. Please share your expertise.
Thanks,
-Seenu

+'STATIC2:Q1-2010;01-Jan-2010,Q2-2010;01-Apr-2010,Q3-2010;01-Jun-2010,Q4-2010;01-Oct-2010'+ in Date From List lets name it P10_DF and
+'STATIC2:Q1-2010;31-Mar-2010,Q2-2010;30-Jun-2010,Q3-2010;30-Jun-2010,Q4-2010;31-Dec-2010'+ in Date To List P10_DT.
(Enable Display Null Value on both the select list)
Then Now in the Report Source add Where Query some thing like
select FIELD1,FIELD2 from TBL_REPORTS where Report_Date>=NVL( *:P10_DF* ,'01-Jan-2010') and Report_Date<=NVL( *:P10_DT* ,'31-Dec-2010')
And also create a button to submit the values
NOTE: This is not tested but this is how i will come about it in the specified scenario. You can try this and post the results...
Good Luck.
