Forms :: Dynamic Where Condition Using Set_block_property?
Nov 7, 2011
I am working on Forms 6i. I have data block A on table EMP.
Datablock A: Empno, Ename, Hiredate
I have FIND Screen: EMPNO, HIREDATE_FM,HIREDATE_TO and FIND Button.
I will search the records through FIND Screen.
I want to set the where condition of block A in pre-query trigger.
set_block_property('BLOCKA',default_where,'HIRE_DATE BETWEEN FIND.HIREDATE_FM and FIND.HIREDATE_TO');
Note: FIND in above is FIND Screen block.
It's not fetching any records, i doubt that there is syntax error in above statement.

I'm using forms 9i. Let's say I have a Block in the form B1. It has two items I1 and I2. I have a table called T1 that has a column say C1. The data in the only record in T1 is 'NAME_IN(''B1.I1'') = 1 OR NAME_IN(''B1.I2'') = 2'..In forms I need to execute the following at POST-QUERY trigger of the block:-
DECLARE
VAR1 VARCHAR2(1000);
BEGIN
SELECT C1
INTO VAR1
FROM T1;
[code]....
As you could see that the IF statement is wrong. But I get the condition (for IF condition) as a string value from some database table.

Have you ever had to add exists to this property? Is this possible?
IF (:VRAN.INSERT_DT IS NOT NULL) THEN
my_where := my_where || ' exists in ( select ''X'',';
my_where := my_where || ' from MON_APL a, mon_hist h ';
my_where := my_where || ' where 1=1 ';
my_where := my_where || ' and a.id = h.mon_id ';
my_where := my_where || ' and h.hist_id = (select max(hist_id) ';
[code].......
So far I haven't been able to get any combination of this working other than what was there:
my_where := my_where || ' INSERT_DT between ';
my_where := my_where || 'TO_DATE (''';
my_where := my_where || :VRAN.INSERT_DT;
my_where := my_where || ''', ''MM/DD/YYYY'')';
my_where := my_where || ' and TO_DATE (''' || :VRAN.INSERT_DT || ''', ''MM/DD/YYYY'') + 1';

I am working on 6i reports.I have below scenario to achieve.
I have FIND window and MAIN Window.
FIND Window: contains EMPNO, ENAME,and FIND button.
MAIN WINDOW: EMPNO, ENAME, SAL, JOB
If i enter something in FIND window, by clicking FIND button, it will populate data in MAIN window.I have below query in WHEN BUTTON PRESSED TRIGGER.
declare
cursor c1 is select empno, ename, job, sal from emp
where empno=nvl(:FIND.empno,empno)
and ename=nvl(:FIND.ename,ename)
begin
--here i am populating data into MAIN window block
end;
It's working fine.
REQUIREMENT: i want to pass where statement dynamically. Let us say if i pass only empno in FIND window, i want to pass 'WHERE empno=:FIND.empno' to existing select statement [I will keep select statement same without where condition]
If i pass empno and ename both, i want to pass 'WHERE empno=:FIND.empno and ename=:FIND.ename.
How to pass where condition to existing select statement based on parameters we pass in FIND window.

I have master detail datablocks. Master block is course and detail block is trainee. students can schedule their courses in a location at particular time.
lets assume student1 has scheduled course A1 in location LA1 from 9am to 12 pm. Now second student shouldn't be able to schedule same course at same time in same location. He can schedule at different time duration. or else same time duration but different location. Or same time, same location but different course.
so, what i did is, i wrote code in when-validate-record of trainee block to display a message saying " cannot schedule course.choose another time." if he try to insert same time duration or same location .
when i am trying to insert a record with time which is already scheduled and in same location, it displays the message but it is also saving the record. i don't want to save the record.
how should i do this? i tried to give ROLLBACK in this trigger but it doesn't accept. i tried pre-insert trigger also but it is also displaying message but saving the record
my code in when-validate-record is:
declare
cursor c1 is
select start_time,end_time,loc
from trainee
where cname=:course.cname;
[code].......

I have a view t1 having the records:
1 A
1 A+
2 B
3 C
4 D
I want to display that in an LOV but without the first record (1 A) I used the code :
SELECT DISTINCT num,
DECODE(num,1,(SELECT DISTINCT desc FROM t1 a
WHERE a.desc='A+'AND a.num=1),desc) desc
FROM t1
this worked fine but how to apply this in a post_change trigger where a user inters the num and the desc appears in atext-item in my form

I receive a "FRM-15004 Error while parsing join condition" when attempting to create a relation between block1 (parent table) and block2 (child table). If I do a simple straight join the statement is accepted but if I use a Decode then it results in an error. How to successfully use a decode or a nvl in a join statement of a relation?
Results in Error:
block1.case_id = block2.case_id and
decode(block1.employee_id, null, block1.entity_id, block1.employee_id) =
decode(block2.employee_id, null, block2.entity_id, block2.employee_id)
This join is accepted but I would like to use a decode since a record can have either a employee_id or entity_id, not both
block1.case_id = block2.case_id and
block1.employee_id = block2.employee_id and
block1.entity_id = block2.entity_id

I have made a travel booking system which comprises of 3 forms
1)Travel Booking form
2)Reservation Form
3)Cancellation Form
Under one booking number i can add multiple users in which they can have there multiple travels.
Users can cancel there individual travels under a prescribe booking number which on doing the Cancel flag turns to 'Y'.
What i want is, If a user is cancelling his/her travel under any booking number then while retriving the records in Travel Booking form, the travels which are cancelled should not be in enable mode.
For one user there can be 4 travels out of which 2 are cancelled, how can i track only those records whoes cancel flag is set to Y. some logic to find it out. Else can i use :system.cursor_record. If yes, How to use it for this system.

I am using Oracle Form 6i. I have created pdf file from oracle report. On view button, I have written:
host('C:Program FilesAdobeReader 8.0ReaderAcroRd32.exe C:dailypending.pdf');
I don't want to set this path on every machine. I want to set its dynamic path so that on which even I machine, I run the applicaiton, it will directly find AcroRd32.exe from any drive either C: or D: or anything else...
It might be Acrobat Reader 9.0 or 8.0 whatever version will be installed on client machine...I want to set path according to that..So that whatever version it would be, it doesnt affect the application..

I want to create dynamic Lov. How can I create it? For practice I create a LOV at design time
RECORD_GROUP_QUERY value:
SELECT * FROM
EMP.
THEN I write some code in WHEN-BUTTON-PRESSED Trigger to replace RECORD_GROUP_QUERY at run time. Code is:
........
v_rg_id:=CREATE_GROUP_FROM_QUERY('TEST','SELECT * FROM DEPT');
........
After this I found a error at run time which is FRM-41826: Cannot replace group; columns don't match LOV.

I'm still trying to import some video in my form.
So far I made one OLE container and add Oracle Video Control, then I made one button and wrote this trigger:
WHEN-BUTTON-PRESSED
declare
video_obj ole2.obj_type;
begin
video_obj := forms_ole.get_interface_pointer
(`MY_VIDEO');ole2.invoke(video_obj,`ImportFileAs');
end;
This works fine. All I want to do now and I don't know why (because I am quite new in Oracle development) is, to make one trigger that will choose automaticly wich video to play and if it is possible to make when I start the form automaticaly to start that video, if not, it's enough just to choose video automaticaly when I press the button.
