Date query in non database block

Hi Experts
I am doing query in a database via a non data base block.The field in which i want to query is join(DD-MON-YYYY hh24:MI:SS) and my non database block is join.
I want that i shall give the date in the join field like DD-MON-YYYY format and the related datafrom the database will come out.
So In the KEY-EXEQRY i have written
IF :system.mode = 'ENTER-QUERY' THEN
IF :EMP.JOIN_DATE is not null then
TRUNC(:EMP.JOIN_DATE):=to_date(:EMP.JOIN,'DD-MON-YYYY');
END IF;
END IF;
EXECUTE_QUERY;
It is showing compilation error.
The construct is not allowed as the origin of an assignment
Can you please tell me what is wrong with it.
detail of join is -
data type -char
Regards
Rajat

To restrict a query to something based on a non-database-block you need a different approach:
1. Do nothing in the KEX-EXEQRY-trigger
2. Create a PRE-QUERY-trigger with the following logic:
IF :CTRL.JOIN_DATE is not null then
SET_BLOCK_PROPERTY('EMP', ONETIME_WHERE, 'TRUNC(JOIN_DATE)=TRUNC(:CTRL.JOIN_DATE)');
END IF;I assumed the following:
- CTRL is the name of your non-database-block and EMP is your database-block
- There is an item JOIN_DATE of datatype DATE in your CTRL-block
- There is a database-column named JOIN_DATE in yourt EMP-table.
- You are using Forms 10g, if not use DEFAULT_WHERE instead of ONETIME_WHERE
If one of these is not TRUE, adjust the code i provided to match your object-names.

Execute query with non database block

How to execute query with non database block when new form instance trigger.

Hi Kame,
Execute_Query not work with non database block. To do this Make a cursor and then assign values to non database block's items programmatically, see following example,
DECLARE
BEGIN
     FOR i IN (SELECT col1, col2 FROM Table) LOOP
            :block.item1 := i.col1;
            :block.item2 := i.col2;
            NEXT_RECORD;
     END LOOP;
END;
Please mark if it help you or correct

Forms - query into non database Block

This is the data in the table. I am querying into a non database block.Have two lines of data
1. 1062|Sanitation and Cleaning|N|1025
2. 1063|Eyewash|N|1025
go_block('qc_procedures');
first_record;
loop
Open C3;
Fetch C3 into :qc_procedures.procedure_id,
:qc_procedures.procedure_desc,
:qc_procedures.optional,
:qc_procedures.procedure_type_id;
Exit when :system.last_record = 'TRUE';
next_record;
Close C3;
End loop;
I am only able to get the first line of data

I'm not quite sure if i understand your problem.
First, you didn't post the definition of your cursor C3.
Second, if you want to populate the block using the cursor, you should loop over the cursor and not over the block, something like
Open C3;
first_record;
loop
Fetch C3 into :qc_procedures.procedure_id,
:qc_procedures.procedure_desc,
:qc_procedures.optional,
:qc_procedures.procedure_type_id;
Exit when C3%NOTFOUND;
next_record;
Close C3;Third, it would be much easier to base your block on a table or on your query (using FROM-clause-query), then there would be no need for any code.

Problem in Execute query on non-database block and database block together

Hi All,
In my form,i have
1. First block is Non-database block with one non-database item.
2. Second and third blocks are database blocks.
Now the problem is that i want to perform execute-query for all the blocks.
If the cursor is on the non-database item of 1st block and i clicks on the "Enter-query" then i am getting message " This function can not be performed here".
If i click on the item of the database block and then clicks on the "Enter-query" and then "execute-query" it's working fine.
But i don't want to do in this way.
My cursor will be on the First block only and then it should perform execute-query.
I am using this non-database item to copy value of this item to the item of the database block item.
I think i make you understand about my problem.
I am using forms 10g on Window xp.
Please help me.

Hi!
Simply create a enter-query trigger on the non-database-block:
begin
go_block ( 'database_block' );
enter_query;
end;If your search criteria is in the non-database-item in the first block,
you actually do not need the enter_query build-in.
Just create a execute-query trigger on the first block like:
begin
go_block ( 'database_block' );
execute_query;
go_item ( :System.trigger_item );
end;And in a pre-query trigger on the database-block copy the
value of your seach item into the item you want to search for.

Query a database block based on a non-database block

hi everybody
can anybody help me as how to query a database block based on a non-database block, without a master-detail relationship?
i have a block : date_input which contains a non-database item: start_date
another database block (event_block)containing details of an event
i have to input a date in the start_date and query the event_block
in wich trigger should i insert the code?
thanks

If you are trying to query your database block (event_block) using the value from start_date in your non-database block, then you can set the Where clause in the database block using:
SET_BLOCK_PROPERTY ('event_block', DEFAULT_WHERE, 'your where clause that includes start_date');
Place this statement in a trigger that is executed prior to the block being queried.

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.
Thansk for all whoe replied.

Tamas

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.

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>

Ordering a non-database block....

Hi ,
Is it possible to order and how a non-database block according to user's willing...????
Thanks , a lot
Simon

That will work in sql*plus but to use it in a program you'll need to parameterise the Order By clause. That's why I wrote mine the way I did. It will work in sql*plus if you enter 'A' and 'B' (including the quotes) and it will work in a program if you replace the placeholders with variables.

Enter_query for non-database block

Hi there,
I have a non-database block. When I click on enter query button from toolbar, i get"this function cannot be performed here' error. I want to bring up records based on certain math calculations. I was planning to write a pre-query trigger and add those to pre-query trigger. Will it work since it is a non-database block? Or should i create a button on form to get records populated?
Thanks

You won't be able to use the Query-Process-triggers PRE-QUERY and POST-QUERY on a non-database-block.
But... If you want to "simulate" the behaviour of querying, you can use the KEY-EXEQRY-trigger and put your logic there. This should also work with the standard forms-menus. To supress the error-message on entering query-mode you should additionally write as KEY-ENTQRY-trigger with code NULL;

ADF : Non Database Block Fields Validation

How should I add validation to "Non Database Block Fields"?
My question is based on this example:
see http://radio.weblogs.com/0118231/stories/2004/09/23/notYetDocumentedAdfSampleApplications.html
"24. Passing User-Entered Data in "Non Database Block Fields" to Stored Procedure/Function"
http://otn.oracle.com/products/jdev/tips/muench/stprocnondbblock/PassUserEnteredValuesToStoredProc.zip
Should I add the validation to an Entity Object (where no fields are 'linked' to database fields) on which I base the "NonDBBlock" View Object?
If this is "Entity Object abuse" (because no database involved, only validation), what would be a better approach?
many thanks
Jan Vervecken

hi Steve
If all the attributes in my Entity Object are marked as not persistent, it makes sense this Entity Object doesn't "take part" in a transaction.
I would like to avoid the message box about Commit or Rollback when closing my Frame, because this use case isn't transaction related in any way.
It seems to work if I override the getPostState() method like this:
public byte getPostState()
return EntityImpl.STATUS_UNMODIFIED;
question :
Are there any side effects to this approach or is there another way to mark an Entity Object as "not in any transaction"?
thanks
Jan

How to query on non database item?

I am working on AP Invoice form. The Invoice Header block based on table ap_invoices_all, I have database items such as invoice_num, invoice_date, and invoice_amount. I also have some non databases item like supplier and supplier number. I added POST_QUERY:
declare
supplier varchar2(240);
supplier_number varchar2(30);
supplier_site varchar2(15);
begin
select aps.vendor_name, aps.segment1
into :invoice_header.supplier, :invoice_header.supplier_number
from ap_suppliers aps
where aps.vendor_id = :invoice_header.vendor_id;
Also in PRE-QUERY
declare
supplier varchar2(240);
supplier_number varchar2(30);
supplier_site varchar2(15);
invoice_num varchar2(50);
invoice_date date;
invoice_amount number;
begin
select aia.invoice_num, aia.invoice_date, aia.invoice_amount
into :invoice_header.invoice_num, :invoice_header.invoice_date, :invoice_header.invoice_amount
from ap_invoices_all aia
where aia.vendor_id = (select vendor_id from ap_suppliers where vendor_name = :invoice_header.supplier);
It's showing fine with Suppier iformation I query by invoices, but I doesn't work when I query by supplier.
Can anyone help? I really appreciate.

Hello,
Thanks for your reply. I think I need to clarify my problem
Your cursor has the same result as what I have in the post-query:
Select aps.vendor_name, aps.segment1
into :invoice_header.supplier, :invoice_header.supplier_number
from ap_suppliers aps
where aps.vendor_id = :invoice_header.vendor_id;
and they both work when I query on a database item, such as invoice_num and the non database item vendor name and vendor number will show up. I am doing ok with this.
My problem is when I query on vendor name field which is not a database item, such as CLARK PUBLIC UTILITIES, it will not return CLARK PUBLIC UTILITIES only, instead it returned all the suppliers. Could you please help with this? Thanks a lot.

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
set_block_property('blockname',default_where,'give neccessery where condition')
in pre_query trigger

Non database block

i have a non data base datablock to view the date and the use(i ssign them at the when new form instance trigger),but the problem that if i make clear all for the form the date and the user will be cleared,so i write the code at when new block instence trigger for the first navigetable data block it works but i think that it is no effient any suggestion???

All our forms have both a control block with basic data (form-name, lookup keys), and a standard clear-all procedure, Whenever user presses the key-clrfrm key, or whenever we re-display all blocks on the form, we first call the U01_Clear_Screen procedure.
U01_Clear_SCreen saves all values in the fields we don't want cleared on the control block into pl/sql variables, then does a: CLEAR_FORM(NO_VALIDATE,FULL_ROLLBACK);It then replaces the saved values into the control-block items.
The Clear_Screen procedure is common to every form, and includes more code if necessary if there are other things that need to be saved/replaced when the screen is cleared.
