Dynamic LOV of past 6 months

I am trying to create a select list item with a dynamic list of values containing the past 6 months like this:
February 2011
January 2011
December 2010
November 2010
October 2010
September 2010
So far I have come up with the following ugly looking select statement that won't order the MONTH/YYYY correctly.
select to_char(sysdate, 'MONTH') || ' ' || to_char(sysdate, 'YYYY') from dual
union
select to_char(add_months(sysdate,-1), 'MONTH') || ' ' || to_char(add_months(sysdate,-1), 'YYYY') from dual
union
select to_char(add_months(sysdate,-2), 'MONTH') || ' ' || to_char(add_months(sysdate,-2), 'YYYY') from dual
union
select to_char(add_months(sysdate,-3), 'MONTH') || ' ' || to_char(add_months(sysdate,-3), 'YYYY') from dual
union
select to_char(add_months(sysdate,-4), 'MONTH') || ' ' || to_char(add_months(sysdate,-4), 'YYYY') from dual
union
select to_char(add_months(sysdate,-5), 'MONTH') || ' ' || to_char(add_months(sysdate,-5), 'YYYY') from dual;
Any ideas?

Try this:
SELECT ADD_MONTHS(SYSDATE,-6) + LEVEL - 1 DT
FROM DUAL
CONNECT BY ADD_MONTHS(SYSDATE,-6) + LEVEL - 1 <= SYSDATE
Thank you,

You know, I used to think that it was awful that life was so unfair. Then I thought, wouldn't it be much worse if life were fair, and all the terrible things that happen to us come because we actually deserve them? So, now I take great comfort in the general hostility and unfairness of the universe.
If this question is answered, please mark the thread as closed and assign points where earned..

Select item on a Tabular form with a different dynamic LOV on each row

I would like to use a tabular form where one of the columns is a dynamic LOV based Select, and where that dynamic LOV refers to one of the column values on each row.
So if the tabular form represented a list of teams and the LOV-based Select column was the current team leader, I would want that select list to be populated only with the members of that team (different for each row). Since the list of team members is in some other table (all_players or something) I would want to populate the LOV with a query with a where clause that selected only those players records with a team-membership equal to the current tabular form's team id. So, on each row that select list's contents would be different.

I'm beating a dead horse here but I did get something to work with "less" code. My current needs do not require me to cascade drop downs, I only want 1. You can use the query like the in the first reply (but I don't have a table with joins) I created a simple two column table dept_emp with 4 records 10,null 20,null .... I want to fill the nulls with an employee but ONLY an employee that matches the dept. (Same concept of team leader and members).
Here's the query:
select apex_item.display_and_save(1,dept) dept,
apex_item.select_list_from_query(2, name, 'select ename from emp where deptno='||dept) name
from dept_emp
I removed the code that was there already (ApplyMRU) and just put in this code:
BEGIN
FOR i IN 1..HTMLDB_APPLICATION.G_F01.COUNT LOOP
UPDATE dept_emp
SET
name=HTMLDB_APPLICATION.G_F02(i)
WHERE dept=to_number(HTMLDB_APPLICATION.G_F01(i));
END LOOP;
END;
The G_F01 matches the column 1 and so forth. There's more documentation but little explanation at:
http://download.oracle.com/docs/cd/B25329_01/doc/appdev.102/b25309/api.htm#sthref2171
The thing I could not get to work was a dynamic message
#MRU_COUNT# row(s) updated, #MRI_COUNT# row(s) inserted.
Not sure when the MRU_COUNT gets populated (probably in the routine I removed ;))
You're probably way past me by now but I like to have as little code as possible when it comes to maintaining an app. That's why I liked oracle forms so much. This kind of stuff was pretty easy to do.
Thanks again everybody!

What is wrong with this dynamic LOV query?

I am trying to create a dynamic LOV which contains calendar week numbers, given a bind var containing the year. If the year given is this year I want the LOV to contain all weeks up to but not including this week, if the year given is in the past I want the LOV to contain all weeks in that year.
Here is my query;
select display_value, week_num from
(select decode(
:P31_YEAR,
to_char(sysdate, 'YYYY'), to_number(to_char(sysdate, 'IW')),
1+to_number(to_char(to_date('31/12/' || :P31_YEAR, 'DD/MM/YYYY'), 'IW'))
) max_weeks,
level week_num,
'Week ' || level display_value
from dual
connect by level < 54
) where week_num < max_weeks
When I try to create the dynamic LOV Apex tells me the query is invalid. It runs in TOAD and as far as I can see follows the LOV query rules.

Try this:
select display_value d, week_num r from
(select decode(
nvl(:P13_YEAR,'2007'),
to_char(sysdate, 'YYYY'), to_number(to_char(sysdate, 'IW')),
1+to_number(to_char(to_date('31/12/' || nvl(:P13_YEAR,'2007'), 'DD/MM/YYYY'), 'IW'))
) max_weeks,
level week_num,
'Week ' || level display_value
from dual
connect by level < 54
) where week_num < max_weeks

Problem with dynamic LOV and function

Hello all!
I'm having a problem with a dynamic lov in APEX 3.0.1.00.08. Hope you can help me!
I have Report and Form application. On the Form page i have a Page Item (Popup Key LOV (Displays description, returns key value)).
When i submit the sql code in the 'List of vaules defention' box. I get the following message;
1 error has occurred
LOV query is invalid, a display and a return value are needed, the column names need to be different. If your query contains an in-line query, the first FROM clause in the SQL statement must not belong to the in-line query.
When i excecute the code below in TOAD or in the SQL Workshop it returns the values i want to see. But somehow APEX doesn't like the sql....
SELECT REC_OMSCHRIJVING d, REC_DNS_ID r FROM
TABLE(CAST(return_dns_lov_fn(:P2_DNS_ID) AS dns_table_type)) order by 1
returns_dns_lov_fn is a function, code is below;
CREATE OR REPLACE FUNCTION DRSSYS.return_dns_lov_fn (p2_dns_id number)
RETURN dns_table_type
AS
v_data dns_table_type := dns_table_type ();
BEGIN
IF p2_dns_id = 2
THEN
FOR c IN (SELECT dns_id dns, omschrijving oms
FROM d_status dst
WHERE dst.dns_id IN (8, 10))
LOOP
v_data.EXTEND;
v_data (v_data.COUNT) := dns_rectype (c.dns, c.oms);
END LOOP;
RETURN v_data;
END IF;
END;
and the types;
CREATE OR REPLACE TYPE DRSSYS.dns_rectype AS OBJECT (rec_dns_id NUMBER, rec_omschrijving VARCHAR2(255));
CREATE OR REPLACE TYPE DRSSYS.dns_table_type AS TABLE OF dns_rectype;
I tried some things i found on this forum, but they didn't work as well;
SELECT REC_OMSCHRIJVING display_value, REC_DNS_ID result_display FROM
TABLE(CAST(return_dns_lov_fn(:P2_DNS_ID) AS dns_table_type)) order by 1
SELECT REC_OMSCHRIJVING display_value d, REC_DNS_ID result_display r FROM
TABLE(CAST(return_dns_lov_fn(:P2_DNS_ID) AS dns_table_type)) order by 1
SELECT a.REC_OMSCHRIJVING display_value, a.REC_DNS_ID result_display FROM
TABLE(CAST(return_dns_lov_fn(:P2_DNS_ID) AS dns_table_type)) a order by 1

I just had the same problem when I used a function in a where clause.
I have a function that checks if the current user has acces or not (returning varchar 'Y' or 'N').
In where clause I have this:
where myFunction(:user, somePK) = 'Y'
It seems that when APEX checked if my query was valid, my function triggered and exception.
As Varad pointed out, check for exception that could be triggered by a null 'p2_dns_id'
Hope that helped you out.

Return multiple values from dynamic lov in apex 3.2.1

Hi
I need to create a dynamic lov that displays multiple values from a table and RETURNS multiple values into display only fields in a form page to be saved to the database
For example
dynamic list of value name SERVER
select name || ',' || life_cycle d, name r
from sserver
order by 1
This SERVER LOV is attached to the P4_SSERVER_NAME field in the form.
However this only returns sserver. name into the P4_SSERVER_NAME field in the form. I would need to capture the life_cycle field as well and populate the P4_LIFE_CYCLE field in the form as well. How does one do this?
I have searched this forum however could not find a thread that fit my situation. i saw that in 4.2 there is dynamic action however unable to upgrade at this moment.
any suggestions are greatly appreciated.
thank you

Hi CRL,
One method is to set the value of your P4_LIFE_CYCLE item via APEX_UTIL.set_session_state
To do this you need to create a Page Process
Type PL/SQL anonymous block
Process Point On Load - Before Header
The source for the Process might look like this: DECLARE
   l_life_cycle   VARCHAR2 (50);
BEGIN
   SELECT life_cycle
     INTO l_life_cycle
     FROM sserver
    WHERE :p4_sserver_name = sserver.name;
   APEX_UTIL.set_session_state ('P4_LIFE_CYCLE', l_life_cycle);
END;Jeff

Variable (Perhaps replacement Path) to group past months together

Hello.
I'm trying to perform a query that would group past months data within the current month to aggregate my Key Figures.
As an example, I have in my InfoCube:
- Material
- CalendarMonth
- Initial Qty (Key Figure)
- Added Qty (Key Figure)
- Substracted Qty (Key Figure)
I'd like to get something like my materials on rows, CalendarMonth on column with my 3 Key Figures on rows as well. The only thing is that all data pertaining to months prior to "Right now (i.e. August 08)" should be aggregated in August 08, therefore, my first month of data displayed would be August and not January 08 if I have data in this month.
This might be very basic to you experts out there but I'm pretty new to the nice BW world and can't figure how to do it. Any help would be appreciated.
Thank you.
P.s. I can't find anywhere (except for the small hints on the right when posting a new thread) how I can format my post as I'd like to put TABS and space but they're getting removed in the preview, is there anywhere the list of ALL possible codes I can use when posting ?

Ok, I've finally been able to manage a "similar" output to what I'm trying to achieve. The total line would actually be a calculated key figure based on the three others. So in the example above, user as specified March 2009 to be the end calendar period he wants to see the inventory "estimates". All data prior August 2008 should be shown in August 2008 in their respective Key Figures and then the "Total" would adjust accordingly. So to answer your question, yes, the same logic need to apply to all 3 Key Figures.

I have the latest version of Abode Reader. However, over the past month or so, my Reader has constan

I have the latest version of Adobe Acrobat Reader. I operate on Windows 7 with Outlook as my e-mail filter. However, over the past month or so, my Reader has constantly become "not responding" whenever I open-up a pdf file that was attached to an e-mail. When trying to read the pdf file, it doesn't allow me to scroll through the document and then goes into "not responding" mode which forces me to exist and then re-open the file many times until I have been able to read the documents. This "not responding" shut down to the pdf file is constant and very annoying. What is going on and how can I fix it?
THanks,

Thank you for your kind and thoughtful input.
My Adobe reader is the most current one that's out there per Adobe.
Something like XII or higher.
As for my Outlook, it's MS Outlook 2003, and I believe it's Express Outlook.
If I disable the Protected Mode, per your suggestion, maybe that will work.
I'll try it.
Thanks again, and if you have any other ideas, I would appreciate your
thoughts.
Thank you.

Need to delete the requirements in md61 screen for the past month

Hi Gurus,
I am having one requirment that my client need to auto delete the md61 screen entries , Suppose the requirement is maintained for 1000 the planned order will also generated for 1000 qty if stock is not available , then the production is done only for 500 quantities. On the next MRP run the system is considering again the past month 1000 quantities .
How we can restrict this? If suppose the balace 500 quantities also the user dont want to produce . Then how can we delete automatically .
Pl help me out this.

Hello Vishnu,
You can delete the old PIRs when the new month begins through batch job for MD74/MD75/MD76.
Other way is to define a period of adjustment for the MRP Group in transaction OMPG and assign the MRP group to your material. Please refer F1 help there
Adjusting in the past, that is the period of adjustment is calculated backwards - the system starts from today's date and calculates backwards by the number of days specified. Thus, planned independent requirements that lie before the date calculated by the system are not included in the planning run.
Please refer

Dynamic LOV based on Current user

How do i make a dynamic LOV based on the user id of the current user.
Also how to insert values from a form into a database
Can anyone please help me out.
Thanks

Use portal.wwctx_api.get_user to get the currently logged in userid.
The simplest example of a form manipulating data is to create the form based on a table. All DML works automagically. You can base your form on a procedure with dummy columns and do your own DML if you wish. Lots more flexibility that way...

Creating a dynamic lov based on a column

Hi,
I want to create a dynamic lov based on a column in a database-table.
Eg. the query
'select code, description from code_table'
is the contents of the column 'lov_query' in the table 'parameters'.
For every parameter there can be a different lov-query, but the result is always
two columns (code and description, number and name, etc.), exactly what you need to use in a lov.
I've written a (dbms_sql) function that takes the parameter-id and returns the lov_query.
create or replace function "GET_PMR_LOV"
(pmr_id in NUMBER)
return VARCHAR2
is
cur INTEGER := DBMS_SQL.OPEN_CURSOR;
fdbk INTEGER;
l_pmr_id NUMBER(9) := pmr_id;
l_stmnt VARCHAR2(2000);
begin
DBMS_SQL.PARSE
(cur, 'select pmr.lov_query from parameters pmr where pmr.ID ' || ' = 'L_PMR_ID', DBMS_SQL.NATIVE);
DBMS_SQL.BIND_VARIABLE (cur, 'L_PMR_ID', l_pmr_id);
DBMS_SQL.DEFINE_COLUMN (cur, 1, l_stmnt, 2000);
fdbk := DBMS_SQL.EXECUTE (cur);
fdbk := DBMS_SQL.FETCH_ROWS (cur);
IF fdbk > 0
THEN
DBMS_SQL.COLUMN_VALUE (cur, 1, l_stmnt);
return (l_stmnt);
ELSE
return null;
END IF;
DBMS_SQL.CLOSE_CURSOR (cur);
END;
But now I'm stuck on how to pass on this statement in HTMLDB
as an dynamic lov, I don't seem to be able to execute this statement
into the two display and return columns. Any ideas?

Hello again,
This lov is on an updatable report-column where the user has to make a choice from an non-named, popup and query-based lov. In the lov-query box I have just put:
"return get_pmr_lov(:p41_param_id)" (without the quotes ;-)
Here's my latest version plus an alternative, which both seem to work fine:
create or replace function "GET_PMR_LOV"
(pmr_id in NUMBER)
return VARCHAR2
is
cur INTEGER := DBMS_SQL.OPEN_CURSOR;
fdbk INTEGER;
l_pmr_id NUMBER(9) := pmr_id;
l_stmnt VARCHAR2(1000);
begin
DBMS_SQL.PARSE (cur, 'select pmr.lov_query from paramaters pmr where pmr.ID ' || '= :L_PMR_ID', DBMS_SQL.NATIVE);
DBMS_SQL.BIND_VARIABLE (cur, 'L_PMR_ID', l_pmr_id);
DBMS_SQL.DEFINE_COLUMN (cur, 1, l_stmnt, 1000);
fdbk := DBMS_SQL.EXECUTE (cur);
fdbk := DBMS_SQL.FETCH_ROWS (cur);
IF fdbk > 0 THEN
DBMS_SQL.COLUMN_VALUE (cur, 1, l_stmnt);
return (l_stmnt);
ELSE
return null;
END IF;
DBMS_SQL.CLOSE_CURSOR (cur);
END;
create or replace function "GET_PMR_LOV2"
(pmr_id in NUMBER)
return VARCHAR2
is
l_pmr_id NUMBER(9) := pmr_id;
l_stmnt VARCHAR2(1000);
BEGIN
EXECUTE IMMEDIATE 'select pmr.lov_query from parameters pmr where pmr.ID = :1'
INTO l_stmnt USING l_pmr_id;
return l_stmnt;
END;
The error-message remains the same, unable to bind :p41_param_id !

How to make use of a static or dynamic LOV in Desktop Instelligence reports

I want to use static LOV as well as dynamic LOV as a prompt for one of my report.
I have created a dynamic LOV but I dont know how to include it as a prompt to my reports. Please teach me the same.
For example I have two classes called COMPANY and EMPLOYEE in my universe. Each entry in the company class will have n number of employees in the employee class. My requirement is when I run the report it should prompt the user to select the company name which is a object in the COMPANY class. Based on the users's input the report should pull the employee data.
For this I have to create a COMPANY name LOV and this should be used in the 'Conditions' section of the Desktop Intellegence.
Please guide me for the same.

Hi,
LEt me know where u need the prompt object to be created in UNV or in report level.
In Unv:
Select Company name object-> double click it and in Select clause define as below
@variable('1. Enter Company Name'')
In Report level: Go to Query panel select Company class object in where clause and select required operator as LIKE OR IN LIST OR NOT IN LIST OR DIFFERENT FROM and select prompt and give some prompt message.
Cheers,
Suresh Aluri.

Dynamic lovs in parameter forms ... Is this possible?

Hi
I am using report developer 10g on windows xp.
I need a cascading prompt style dynamic LOVs in my report parameter form.
The first LOV displays a set of values (say for eg. dept list). The second LOV will display another list, based on the value chosen by the user in the first LOV (Eg. List of employee names in that dept).
My first LOV select statement may look like below for the user parameter say P_DEPT
select deptno from dept;
My sencod LOV select stmnt may look like below for the user parameter P_EMP
select ename from emp where deptno = :P_DEPT
Each time I try to set the second LOV, report developer complains "Bind variables not allowed in select statement"
Same error msg comes if I reference the first user parameter(P_DEPT) as a lexical parmaeter.
How do I acheive the above in report parameter form? Any help is appreciated greatly...
Thanks
Suma

Hi Brad,
Thanks for the reply. I had almost given up hope on receiving replies to this message.
I do agree that it is simpler (and a lot striaght forward) to just use forms to develop dynamic LOVs of cascading prompt style, that is required in my app. But in our shop, we have integrated forms and reports in such a way, that all the report parameters are handled by report developer's own parameter form, rather than coding a separate logic on the forms side to handle the report parameters(as this has to be done on the forms side for every report that we generate, We thought it would be better to use the reports developer to handle the parameter input and then pass the .rdf to forms app). Currently in all our app, the parameter form generated by the report developer is rendered as HTML form on the browser (when the concerned rdf file is called within the forms app) and by submitting this we get the report output)
Hence I am very keen to get this done somehow on the report developer side.
I do hope I get some input on this. Also, its a little surprising that such a simple feature is not readily avalibale in the report parameter form. I hope oracle report developer team is reading this message...:)
Thanks
Suma

I have been dragging my files to a external drive to have a back-up for them and I lost some of my folders. They just went completely missing. I didn't delete them, and it was all stuff that I have worked on in the past month. How do I get them back?

You really should be doing backups with an actual backup application, especially one that will work automatically, and, if your external HD is large enough, back up your entire system. These can automatically back up only what's changed since the previous backup, and some will keep "archive" copies of things you've changed or deleted, also.
Too many things can go wrong, such as your internal HD failing, and you'll have a major project to reinstall everything.
You already have Time Machine, built-in to OSX. You might want to review the Time Machine Tutorial, and perhaps browse Time Machine - Frequently Asked Questions.
#27 in the second link mentions some alternatives, too.
