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 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.

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 ?

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;

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>

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.

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.

Querying an indexed database column. How?

Hi there,
I am pretty good at CF and okay at SQL.
Over the years I have been informed that when using the same column in a database multiple times to do look-ups....e.g. a primary key field....that it would be best to "index" this column to improve speed.
However, I'm not fully sure what or how to index a database column. I have a few questions:
Is it something to do in MySQL directly? Or can it be done programmatically with CF?
Does it really speed things up a lot?
How is new data entered affected? Does that new data get included into the index?
Does my cfquery syntax have to be any different than is normal?
Any help or advice would be great.
I'm using CF8 and MySQL5 (query browser tools etc)
Thanks,
Mikey.

Indexing is a database topic. As databases can be controled by SQL commands it would most likely be possible to do so inside of a <cfquery...> block, but I would only do that in rare circumstances.
Indexing a table will almost always speed up frequently used database columns. But when, how and why one would index a database column is a big topic on which entire papers, books and college classes have been developed around. I would start with some reading of you database documentation an then branch out onto the internet. You will find much written and should be able to educate yourself easily.

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.

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

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.

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,
Madonna

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.
