I have developed a report using apex shared components (report query and report layout) along with BI Publisher for report printing in pdf format. the Report template is built using Template Builder for Word. I have configured my Apex4.1 env with BI Publisher 11. This report is working fine for hardecode ID ( like REQUEST_ID=10 ). to make report dynamic i have made following additions in the report
I have added where clause in report query as WHERE REQUEST_ID = :REQUEST_ID (:REQUEST_ID is the text field in my page).
Added a text field names :REQUEST_ID to get user input at run time.
Create a button and add Repot Query URL in its properties. When i run the report with some valid value in :REQUEST_ID text field i did not get expected result infect there is no record getting displayed in the PDF file. i think this is not the write way to do this but interestingly im not getting any error. how can i get this functionality in apex this way or the other ?

We receive hand punches (clock data) every day. Normally a person badges in(hand punch) which creates a row in the clock_tran_processed table. The information from that hand punch is the employee id (emp_id) the date hand punch occurred and a work_summary id (wrks_id). At the end of the day, the employee badges out (hand punch out) and another entry in the clock_tran_processed table is created. The new row will have the emp_id (employee name), date the hand punch occurred and the same work summary id from the morning.
Normally hand punches should occur in pairs. One in, one out... or one in, out for lunch, in for lunch, out for day. I am seeing intervals of three and five. Meaning the employee clocked in twice and out once, or in once and out twice. This shouldn't happen.
I am writing a report that will show number of clocks per for all employees that have three(3) or five(5) clock entries.I wrote a ref cursor that gives all the employees that have a count of 3 or 5 and the employee id (emp_id). I need to pass that employee id to another query that will then get me the dates of the clocks.Here is the ref cursor thus far (I am printing those with a count of 3 and 5).
CODEDECLARE
TYPE ClockTran_Refcur IS REF CURSOR;
ClockTran_cur ClockTran_Refcur;
NumClock_num number :=0;
NumClock_name clock_tran_processed.emp_id%TYPE;
[code]...
How do I pass that variable to the get the clktranpro_time's? I am using "Easy Oracle PL/SQL Programming" but I am not seeing this type of example(pgs 140-148).

Seems it's not able to identify R.PARTITION_NAME in update statement. Are you aware whether we can partition name like this if we need to update based on partition names in a cursor.
My cursor code is:
DECLARE
CURSOR C_PARTITION IS
SELECT PARTITION_NAME, PARTITION_POSITION FROM ALL_TAB_PARTITIONS
WHERE OWNER = 'FACTS'
AND TABLE_NAME = 'TABLEA'

Oracle Version: 11.2.0.2.0. I have two explicit cursors and I would like to choose at run time which one to run. Here is a simplified code snippet of what I am doing today:
DECLARE
CURSOR Cursor_A IS
SELECT * FROM EMP_A;
CURSOR Cursor_B IS
SELECT * FROM EMP_B;
RUNA CHAR(1) := 'Y';
[code]....
I want to avoid maintaining the same long list of transformations. I also want to avoid, if possible, an explicit FETCH INTO, because there are hundreds of fields in both tables. I'm looking for something like this (and I know this doesnt work):
DECLARE
CURSOR Cursor_A IS
SELECT * FROM EMP_A;
CURSOR Cursor_B IS
SELECT * FROM EMP_B;
RUNA CHAR(1) := 'Y';
CursorToRun IS REF CURSOR;
[code]....

I´m newbie as Apex developer using Apex 4.0 with OracleXE 11.2, and now my problem is:
I have a tabular form where one of the columns, when calling the form, is a Display Item, so that you cannot change existing values.
I want, when adding a new row, that column become a Select List (named LOV) based on a query that exclude existing values in other rows already inserted.
Can I change that Display Item to Select List (named LOV) programmatically at runtime? If not, what other options do I have?

I have an Interactive Report with a column that I need to create a link on but I need to pass the value of another column.
This report shows the Features of a particular Release. There is a select list for the Release that is selected and executes the report. There is a column that indicates whether the Feature has a Commitment attached to it. If there is have that a link to another report that shows all the Commitments for that Feature by passing the FEATURE_ID which is also a column on the Feature report.
Query:
SELECT
....
,CASE WHEN ft.feature_id IN (SELECT cc.feature_id
FROM customer_commitments cc
WHERE ft.feature_id = cc.feature_id
) THEN 'Yes' ELSE 'No'
END "Commitment Exists"
,ft.feature_id
....
FROM ....If "Commitment Exists" has a 'Yes', the 'Yes' is a link that will pass the FEATURE_ID to another report that will show the Commitments for that Feature. If the "Commitment Exists" has a 'No' then no link. I was also wondering if the Commitment report could open in a seperate window and make it modal?

So, for lack of a better way to explain it, I need to do the following.
I need a EXECUTE IMMEDIATE to be able to use a CURSOR but its saying its not declared. Is their a way to pass the cursor so a Execute Immediate can use it...
V_SQL := 'REPLACE(V_DATA,'TEST',CUR_DATA.'||V_FIELD||');';
EXECUTE IMMEDIATE (V_SQL);
I know thats just a small part... but it shows the end goal. I need to append a VARCHAR that has the COLUMN NAME I need from the CURSOR. CUR_DATA is the open cursor. V_DATA is just a VARCHAR with text in it.

i want to produce a function who return XmlType element if she checks that a parameter (that i passed to here is contained in a row in a defined table)
for example
create table sec_form(
form_code VARCHAR2(8)
, sec_code VARCHAR2(5)
) ;
insert into sec_form values ('CSA','section1');
insert into sec_form values ('CSA','section2');
insert into sec_form values ('CSA','section3');
then i got my function
create or replace function checkIfSectionEnabled (elem XmlType,name_section varchar2)
return XmlType
is v XmlType;
CURSOR myCursor IS select * from sec_form where form_code = 'CSA';
begin
open myCursor;
loop
[code]....
now i'm gonna call the function (elem XmlType,name_section varchar2) and pass here "section1" for example ; and she must return me my xmltype element if she find "section1" finds section1 present;
when i try t compile i got:
Error(18,13): PL/SQL: Statement ignored

I'm dealing with an ORA-1000 error in a Pro*C application where all the cursors are correctly closed (or so it seems to me).
Here is the code for a simple program which reproduces the problem:
Each cursor is opened in a PL/SQL package:
CREATE OR REPLACE PACKAGE emp_demo_pkg AS
TYPE emp_cur_type IS REF CURSOR;
PROCEDURE open_cur(curs IN OUT emp_cur_type, dept_num IN NUMBER);
END emp_demo_pkg;
[Code]....
While testing the initialization parameter open_cursors is set to 50.
It's my understanding that Oracle doesn't close the cursors until it needs the space for another cursor, which in my test case seems to happen when I enter a value of 50 or bigger for "number of loops". To see how oracle is reusing the cursors, while the test program is running I run SQL*Plus and query v$sesstat for the session that's running the test with the following sentence:
select name, value
from v$sesstat s, v$statname n
where s.statistic# = n.statistic#
and sid = 7
and name like '%cursor%';
Even before I enter a value for number of loops I can see that the session opened 4 cursors and closed 2 of them:
NAME VALUE
---------------------------------------------------------------- ----------
opened cursors cumulative 4
opened cursors current 2
Entering a value of 5 for number of loops yields
NAME VALUE
---------------------------------------------------------------- ----------
opened cursors cumulative 11 <----- 7+
opened cursors current 8 <----- 6+
With a value of 30
NAME VALUE
---------------------------------------------------------------- ----------
opened cursors cumulative 36 <----- 25+ (apparently, Oracle reused at least 5 cursors)
opened cursors current 33 <----- 25+
With a value of 47
NAME VALUE
---------------------------------------------------------------- ----------
opened cursors cumulative 53 <----- 17+
opened cursors current 50 <----- 17+
Now I reached the upper limit set by the initialization parameter open_cursors.
Entering a value of 48, I get the ORA-1000 error.
ORA-01000: maximum open cursors exceeded
ORA-06512: at "SCOTT.EMP_DEMO
Since I open and close the cursor in the same loop iteration, I expect to find in every iterarion 1 explicit cursor and a number of implicit cursors (the PL/SQL call along with the so-called recursive cursors), but I don't expect the sum of all of them to be greater than 50. If my understanding is correct Oracle should be reusing the 50 cursors previously marked as "closeable", not raising the ORA-1000 error.
