Deleting a non-database column

Hi,
In forms, i have one field, manager_id, database block = YES, but it is not visible on any canvas. Instead of this, the non-database item manager_name is displayed in form, and populated from a post-query trigger (with the name of the manager). Is there any property, or something, so if i delete the content of a particulat manager_name (set it to null), the manager_id also sets to null?
Thanks

Write a POST-TEXT-ITEM Trigger on the Manage_Name field to set the Manager_id to null
IF :MANAGER_NAME IS NULL THEN
:MANAGER_ID := NULL;

How to access a non-database column in a report?

Hi all,
I would like to populate a column in my report, which is not based (in Oracle Forms, it is a "non-database item").
But I don't know how to access it. Let's say the alias of the column is "column", I tried to do it with #column#, but it's not valid.
Does anyone know a solution here?
Thanks a lot,
Dovik

Where do you need to access the column value ? Are other columns of the report accessible from where you are trying to access the value of this 'non database' column ?

Non Database Column to Grid Control

Hi,
How do I add a Non database column to a Grid Control which is
based on a Rowset. I want the similar functionality of a
multirow Block in D2K Forms, which is based on a Database query
and to which another item is added which is non Database item
and it is also displayed as any another item in the same
multirow block. The updatable and queryable property for this
item is set to false.
How do I get similar functionality in JDeveloper using InfoSwing
GridControl. Thanx in advance.

The GridControl does not have built-in support for this
functionality. However, the GridControl source code is provided
so you can extend the control to provide this functionality.
In 3.0, the Oracle Business Components for Java will provide the
ability to create objects that can mix db and non-db attributes.
The GridControl can then be bound to this object to provide the
functionality you seek.

Query a non-database column

My main table is SR_TECHS which has tech id and Techname
My second table and block is sr_tech_calendar.
Here tech_name is a non-database field.
When I type J% in the Tech_name field and query, I should be able to get all tech_names
starting with 'J'
How can I get it through pre-query and what should I do in the post-query?

you achieve this by setting

Not able to perform computation on Non Database Column in Tabular Form

Hi All,
          I have a Master and a Detail Tabular Form which has the following requirement:
If I choose Two Way in my Trip Type item in my Master form,the No of Tickets field in my Detail Tabular form has to get doubled ie. 2*No of tickets
The No of Tickets is a Display as Text(does not save state) field so I am not able to select the value of the field in jquery.
Kindle help me with this.
Thanks and Regards,

I have added a true and a false action to the dynamic action disable.
Here is the code of the false action. The action type is Execute JavaScript Code
/*Select all input elements with the name attribute f14*/
apex.jQuery('[name="f14"]').each(
function(){
    var lNoTickets,lSpan;
    /*Calculate the number of tickets by getting the value and times 2*/
    lNoTickets =(this.value*2);
    /*Determine the display element*/
    lSpan = this.nextSibling.nextSibling;
    /*Set the new number of tickets to the display element*/
    apex.item(lSpan.id).setValue(lNoTickets);
     /*Set the new number of tickets to the hidden element*/
    this.value = lNoTickets;
Because you have used "Display as text(saves state)" apex renders both an input item of type hidden. And a span element that displays the value.
Both these elements need to be set separately. See the last two lines of the code.
The calculation of the new Number of tickets happens for each hidden element with the name f14.
And the span element is the second sibling of the hidden element.

Non-Database Item Sort Using Multiple Block Values

I need to sort the result set of a block based on a calculated item. I found several messages addressing this, however they all speak to using the columns from within the same block as input variables to the function used to calculate the non-database column value.
My problem is that I need to use values from a different block as input variables. I have not found a way to use them since I need to use the full block.column syntax. Forms does not like this and always thows an error right at the period(.). I need to do this because the column names are the same in each block. the function compares the column values and changes the record instance background a different color based based on how many of the column pairs match. Each block is mutually exclusive from each other and doing a accurate join is not really possible.
I tried renaming the block column name to something unique, however I get a variable not bound error when I try to use it in the order by function even though their values are in the top most block.
For Example:
First Block. Contains a list of cases that need to be worked because the automated process could not find a valid provider based on the values received. This list is created by a background process.
Table: CASE_MAIN
TIN
CASE_ID
FCLTY_CM
MEDICARE_CM
Unrelated Second Block (i.e., no join). It uses the TIN value in the first block to get a list of all of the providers for the TIN associated with the Case so that a person can assign the correct Provider to the case (A TIN has a provider and address associated with it). As a result there is no link to the results of this table and the CASE_ID. That's what the users needs to do manually
Table: PROVIDER_MAIN
FCLTY
MEDICARE
I need to take the values in the first block and compare them in the second block so that I can recolor the background based on matching logic in the function below.
order by clause = get_vals( ''||:FCLTY_CM||''
,''||:MEDICARE_CM||''
,fclty
,medicare) desc
I am able to do the coloring within the form easily, however I need to order them by how many values match exactly so the ones that match to most value pairs show at the top. Hence ordering by the result of the function. I return a 0,1, or 2 based on the matches. 0 for none and 2 for both.
I cannot create a view because the sources of the information I need to compare are NOT related to each other, yet. that is what the application is designed to do. I have a case without a
provider assigned, but I have a tax id number that possible identifies the provider. I use this TIN to query the provider table for all of the possible providers under that TIN. As a result there is no link between the case information and provider information. The goal is to get this list compare the values from the target information and put the most likely matches on top, with
the ones with the most matches first. I can create a function many ways that takes in various parameters. For example Case ID and Provider Id and query the records in subselects
individually like so;
select count(*)
from (select fclty, medicare from case_main where case_id p_case_id) cm
,(select fclty, medicare from provider_main where prv_id = p_prv_id) pm
where cm.fclty = pm.fclty
and cm.medicare = pm.medicare
If the number is greater than zero I know I have a match with that provider and I can sort accoringly. I can also pass in the target information from case_main and the provider inforation from provider_main and then do an if/then statement for comparing. Then I can use this function to create a column value for each record and then use the same reference to the function in the order by clause to order by that value.
The problem comes in trying to reference the case_id or target information from a different block than where the fucntion needs to be used. I get a variable bound not error message. What am I missing here. Why can I not reference a uniquely named block item as a input variable to a function in a different block? Does Forms first figure out what it needs to retrieve and then executes the SQL for each block in isolation, or does the first block's result set get retrieved, then the second, third, etc. Based on the message i am getting I would suspect the former since it appears their is no value in subsequent blocks. If so is there anyway around this? thanks.

Don't quite understand your problem completely. But this might help. I sure hope your Provider_Main is a single-record block ...otherwise, how would you supply a list of values of FCLTY and MEDICARE to the function that does the sorting? Be awere, too, that the order-by is processed by the server, and NOT by Forms.
Assuming it is a single-record block, you can put the values into parameters:
:Parameter.Fclty := :Provider_Main.Fclty;
:Parameter.Medicare := :Provider.Medicare;
Execute_Query;
And your order-by clause would be
get_vals( ''||:FCLTY_CM||'',''||:MEDICARE_CM||'',
:Parameter.Fclty,
:Parameter.Medicare) desc
By the way, the first line of your order-by looks strange. Shouldn't it be:
get_vals( FCLTY_CM || ',' || MEDICARE_CM,
or even better, get_vals should take in 4 parameters:
get_vals(Fclty_cm, Medicare_cm, :parameter.Fclty, :parameter.Medicare)

Update of non-database fields mapped to database fields

I have two columns start month and start year which
are non-database columns and which map to one database
field start date in the database.
I have a post-query trigger on the start month and
start year fields to derive the value from the
database field start date when the form is queried.
When I try to update the form, the update does not
work - if I remove the post-query trigger then the
update works but, the month and year non-database
fields do not get queried.
Any help will be greatly appreciated.
Thanks,
Suzanne

since those 2 fields are not connected to the database field you need to code the update to the database.
Use the pre-insert trigger and set the value of the date item according to the values of the 2 fields.

Chidu,
The result set that you get back is a JDBC ResultSet, not a "JATO" resultset. In ND, everything was wrapped in a "spider" data
structure, and therefore, difficult to get to the underlying datastructure, in many cases. In some case ND made it easier to do
certain things, and in other ways, made it more difficult or impossible(like seeing the SQL for an insert, update, delete).

HOW TO CREATE MULTIPLE RECORDS IN A NONE DATABASE BLOCK?

I have a Form where I have a none database block with unbound items. The block
has 10 records. In the when-new-block instance I run a query by which I would
like to fill up the block with data. The code fragment looks like the
following:
begin
declare
tmp_curr_rec_id number;
begin
-- a hibak kiolvasasa
for c_hibak in ( select h.*, h.rowid
from hibak h
where 1=1 -- WF - Ide kerul a szurofeltetel
order by bejelentes_datum asc
) loop
-- bemasoljuk az adatokat az unbound item-ekbe
:mc_adat.ub_azonosito := c_hibak.azonosito;
:mc_adat.ub_verzio_letrehozas_datum :=
c_hibak.verzio_letrehozas_datum;
:mc_adat.ub_bejelento := c_hibak.bejelento;
:mc_adat.ub_bejelentes_datum := c_hibak.bejelentes_datum;
:mc_adat.ub_wf_verzio_csomopont :=
c_hibak.wf_verzio_csomopont;
:mc_adat.ub_wf_utolso_esemeny_szoveg :=
c_hibak.wf_utolso_esemeny_szoveg;
:mc_adat.ub_hiba_leiras := c_hibak.hiba_leiras;
:mc_adat.ub_hiba_hely := c_hibak.hiba_hely;
:mc_adat.ub_rekord_jelleg := 'H';
:mc_adat.ub_rowid := c_hibak.rowid;
-- beallitjuk a rekordot-ot olyanra, mintha semmi nem valtozott
volna
-- nem szeretnenk a form bezaraskor mindenfele figyelmezteteseket
-- olvasni a kepernyon
tmp_curr_rec_id := get_block_property( :system.current_block,
current_record );
set_record_property( tmp_curr_rec_id, :system.current_block,
status, new_status );
create_record;
end loop;
end;
end;
The block's update allowed, insert allowed, delete allowed property is set to
true.
The result of the code above is that only the last record fetched shows up in
the block. The problem is - as I found out - is that aech record is fetched,
the values are copied to the block items, but the create_record built-in
command would not move the cursor to the next row.
Can some one please help me with this?
TIA,
Tamas Szecsy

The problem was with the following code segment:
tmp_curr_rec_id := get_block_property( :system.current_block, current_record );
set_record_property( tmp_curr_rec_id, :system.current_block, status, new_status );
After omitting these two lines, the code worked properly.

Querying a record from a non-database item

I am working in Apex 4.0. I have a page based on a table with the following columns: dktnr, borrower, amount, previous_dktnr, subsequent_dktnr. The precious_dktnr is the dktnr under which the loan was financed in the past, before its assumption or refiancing. The subsequent_dktnr is the dktnr under which the loan is later identified. When a loan is refinanced, it is assigned a new dktnr in a new record, and the old dktnr is placed in the previous_dktnr column of that new record, and the current dktnr is placed in the subsequent_dktnr column of the old dktnr record.
I created two buttons, one for the previous_dktnr and one of the subsequent_dktnr. When I click either of these buttons, the action redirects to the current page and places the value of either the previous or subsequent dktnr into the dktnr item. This queries the record for the dktnr that has the same value as the previous or subsequent dktnr.
This works. It allows the user to shuffle back and forth between the two dktnr's.
One would assume then that, if a non-database item were created, say :P22_QUERY_DKTNR, you would be able to enter an existing dktnr into that item and have a button, using the same logic as the previous and subsequent dktnr buttons, that would be able to return the record for the dktnr entered.
I have tried this, and it does not work. Can anyone tell me why it does not work?

Doug,
Made copies of your two page within your workspace, page 3 & 4.
The issue was the page did not have a value in session containing your Look_Up value. I altered the Look-Up button to Submit the Page so as to capture the Look_Up value and then added a new Page Branch that was sequenced prior to your existing branch. This new branch sets your P4_DKTNR with the Look_Up value and then returns your results.

Insert Image to table from a Non Database Field

Hallo,
db- 9i EE R2
forms - 6i R2
OS - W2003
I have a requirement to upload Images to the database from forms.
I planned to keep the transaction data and the Images separately in different tables with a reference.
So, I created the Image field (BLOB) with a Non Database Field in the Form and use a button to upload the Image. (using READ_IMAGE_FILE).
I tried to insert the Image to the Actual Image table in PRE-INSERT Trigger at block level.
But I was not able to Insert the using reference method. (Cannot compile the PRE-INSERT)
INSERT INTO IMAGE_TB (ID,IMAGE)
VALUES (IMAGE_SEQ.NEXTVAL, :ITINERARY_MAP.IMAGE);
So, Please help me to insert a image to different table from a Non Database Field?
Thanks

I don't think it will work with a non-db-item. But you could create a separate block based on your image_tb-table, use read_image_file on the then db-based-column and then simpy issue a commit_form.

Region sql query(updateable report) data entry in non db columns

In a tabular report type updateable report
What is the best way to provide data entry into a non db column a) (to accept parameters for some on demand pl/sql processes)?
Only when setting a) as a standard report column the db insert/update transaction can be processed
When changing a) to text field the db insert/update transaction fails with en error (screen/db are not in sync which is not actually the case)
a) should not be part of the db insert/update transactions but still allow data entry
How can this be achieved?
Thanks
Peter

Hi Peter,
I think the easiest solution is to use an updateable view instead of the direct table access.
Here is an example:
CREATE OR REPLACE VIEW V_EMPLOYEES
AS
SELECT EMPLOYEE_ID
     , FIRST_NAME
     , LAST_NAME
     , FIRST_NAME||' '||LAST_NAME AS FULL_NAME
FROM EMPLOYEES
CREATE OR REPLACE TRIGGER TRG_V_EMPLOYEES
    INSTEAD OF INSERT OR UPDATE OR DELETE
    ON V_EMPLOYEES
    REFERENCING NEW AS new OLD AS old
    FOR EACH ROW
BEGIN
    IF UPDATING
    THEN
        UPDATE EMPLOYEES
           SET FIRST_NAME = :new.FIRST_NAME
             , LAST_NAME = :new.LAST_NAME
         WHERE EMPLOYEE_ID = :old.EMPLOYEE_ID
    -- insert and delete is not allowed
    ELSIF INSERTING
    THEN
        NULL; -- there would be a insert code
    ELSIF DELETING
    THEN
        NULL; -- there would be the delete code
    END IF;
END;
/FIRST_NAME||' '||LAST_NAME AS FULL_NAME in the example view simulates your function call.
There might be a possibility to do it in APEX as well, but that was the first solution which came into my mind.

How to display records from a query into non-database field

Hi
I a have a problem:
I have a query with many tables and 6 column(select a,b,c,d,e,f from x,y,z,t,s,g where conditions) and I use 3 parameters.
I create 3 parameters :datai,:dataf and :partener and a button with a trigger when button is pressed.
Then a create a manualy block with six field non-database a1,b1,c1,d1,e1,f1.
Now I want to display all the records from my query into a1,b1,c1,d1,e1,f1 where a1=a,b1=b,etc. and all the records (if I have 20 record, it will display 20 records in non-database field) when I press the button.
How I made:
I create a cursor with query then
begin open cursor
loop
fetch cursor into :a1,:b1,:c1,:d1,:e1,:f1;
end loop;
close cursor;
end;
It display one record in a1,b1,c1 only and it have to display 100 records and are date for all the fields.
Can somebody help me in this problem?
Thanks.
Edited by: 928437 on Oct 1, 2012 2:55 AM

Creating a view, and querying that into a database block is an excellent solution.
To use the non-database block:
You're missing the all-important Next_Record; command.
<pre> Begin
Go_block('X'); -- block X is the non-database block
Clear_Block(No_Validate);
open cursor X1;
loop
If :System.Record_status != 'NEW' then
Next_Record;
End if;
fetch X1 into :a1,:b1,:c1,:d1,:e1,:f1;
Exit when X1%NOTFOUND;
end loop;
close X1;
end;</pre>

Sorting a block on a non databsae column dynamically

Hi Folks.
I need some ideas to sort a multi record database block on a non data base coloumn dynamically.
The situation is like this: I have a base table multi record block with emp_id one of the columns.
and i have emp_name as a control item in the same block. I am populating the emp_name field at run time in
POST-Query and When-New-record-Instance triggers by fetching the corresponding values from the database
for the current emp_id. i need to sort the rows on either emp_id or emp_name in asc or dsc order with the
click of a button. i can change the ORDER BY property of the block to sort by emp_id asc or desc.
But how i can sort the rows by emp_name dsc or asc.
Any suggestions are welcome and will really be helpful
Thanks
Pranati

Hi,
     Try out this...
     In the property palette of the block enter the names of both tables seperated by comma in the block property palette 'query data source'. In the where clause of block property palette or in the set_block_property(block_name, default_where, 'where_condition') join these two tables. And in the order by clause of the block property palette or in the set_block_property(block_name, order_by, 'columns') specify the order by fields. And populate non-database empname field by post-query or you can make empname as database field and execute the query.
     I think this will solve the problem.
