Exiting from a Block that is in Enter-Query Mode

hello,
can anybody show me how to cancel the query of block "x" and go to block "y", when block "x" is in enter-query mode, and the user navigates using the mouse to a field in block "y".
thanks

Hi, Samir
Please create the following WHEN-MOUSE-CLICK trigger in your second block.
If you don't want to activate enter-query mode when you click on the second block, simply remove the "enter-query;" line below.
if :system.mode = 'ENTER-QUERY' then
declare
oldmsg varchar2(2);
begin
oldmsg := :system.message_level;
:system.message_level := '10';
exit_form;
:system.message_level := oldmsg;
end;
next_block;
enter_query;
end if;When the mode is ENTER-QUERY, some built-in routines change their behaviour. EXIT_FORM; is used to cancel the enter-query mode.
Hope this helps,
Pedro.

Forms that start in enter query mode freeze on exit

When a headstart form is called from
a menu and the first thing it does if go into
enter query mode the form will not exit properly, causing the orginal form to hang.
Is there any work around for this apart from taking enter_query out of the when_new_form_instance trigger ?

We have a similar problem with a Headstart generated application. We are unable to pinpoint it entirely to forms that start in enter query mode as:
a) forms that don't start in enter query mode also hang; and
b) not all forms that start in enter query mode do hang.
The problem doesn't seem to affect a form consistently, as one day it will hang on the first use, the next it will work for several hours.
When a new form is selected from the menu the toolbar is not shown, the 'start' form disappears and the application hangs. It is then necessary to close the application using Task Manager.
The good news is that this only seems to happen in our development environment (Windows NT 4) and not in our live environment (Hydra).
We are working with Headstart v2.1.2.0.1,
Designer v2.1.24.1.0 and Forms v5.0.6.11.0.

EXIT_FORM in enter query mode

Hi Guys,
I have a button on my form to exit the form code is:
EXIT_FORM(No_Validate);
when my form is in enter query mode the button does not work. i have to cancel the query first and then the button works.
How can i change my mode to exit form even if it is in enter query mode.
Please help its urgent.
thanks , Imran Baig

HI Imran,
That is quite normal. If you press CTRL/Q, it executes an implicite Key-EXIT trigger. If you are in Enter Query mode, this will close the query and does nothing else. When you execute it again, you leave the from without validation.
My suggestion were: Place the exit_form(no_validate) twice in your trigger--the second would be absolute harmless, since the form will no longer be active, provided you came from Normal Mode. Otherwies, it will force leaving the form by first closing the query and then leaving.

Change Value of Veriables in Enter-Query mode

hi all
I have made a search utility on a table, there is reqirement that in the enter-query mode the user can enter any combination of character, in simple words there is requirement of %% at begining and at end of desired search field.
as :system.last_query gives the value like
SELECT ROWID,SEQ_NUM,TAG
FROM sequel1.sequelsql WHERE ( UPPER(TAG) LIKE :1 and (TAG LIKE :2 or TAG LIKE :3)) order by TAG
how to pad % sign in the veriables :1,:2 and :3 as need to search
tag like ('%ASSESSMENT%')
thanks in advance

SELECT ROWID,SEQ_NUM,TAG
FROM sequel1.sequelsql WHERE ( UPPER(TAG) LIKE :1 and (TAG LIKE :2 or TAG LIKE :3)) order by TAG
1.
have you tried to handle the items contents in a PRE-QUERY trigger ?
If blk.item IS NOT NULL Then
:blk.item := '%' || :blk.item || '%' ;
End if ;2.
You could change the WHERE clause (or the ONETIME_WHERE)
in your KEY-EXEQRY trigger:
Declare
req Varchar2(512) ;
Begin
req := '( UPPER(TAG) LIKE %' || :blk.item1 ||
'% and (TAG LIKE %' || :blk.item1 || '% or TAG LIKE %' || :blk.item3 ||'%)) order by TAG ;
Set_Block_Property( 'blk', DEFAULT_WHERE, req ) ;
Execute_Query ;
End ;Francois

Enter-Query Mode

I'm interested in starting a discussion on the restrictions of
Enter-Query Mode, principally, why can you not navigate to a
query only block whilst in this form mode? I have successfully
implemented an full Query functionality without using the
default forms behaviour, and wonder if there are any
disadvantages that I have overlooked.

Hi there,
Its quite involved, I have some documentation that goes some way
to describing the problem/solution, but briefly I find that when
in 'Enter-Query' mode (system.mode = 'ENTER-QUERY') there are
two restrictions
1) You cannot navigate to another block. This is useful in a
number of cases, like if you want to implement a more powerful
List of Values facility, or provide the user a seperate screen
to build up complex query criteria
2) If you write a trigger that uses 'enter_query' built in,
processing stops at this point. The standard workaround for this
is to start a timer before the call to 'enter_query', and when
the timer expires it performs the processing you want to do
after 'enter_query'.
So, I decided to rewrite the default forms enter/execute query
processing (which was pretty straightforward), so my forms never
go into 'Enter-Query' mode. What I am interested in is if there
is anything that using the default forms processing gives, that
I may have missed!

Prevent exit from a block

Dear members,
I have a block on a stacked canvas. I want the user to exit only by clicking on a particular button. Thus I created a POST-BLOCK trigger to raise a form_trigger_failure if the user clicks anywhere else. It just checks if the view is visible. The button then just has to hide the view before exiting, so the trigger lets it do it.
The problem is that I want the user to be able to commit its work while on the block. But when I execute a 'COMMIT_FORM', Forms tries to exit from the block, gets the form_trigger_failure, and stops committing.
The solutions could be:
- To find another way to prevent the user from exiting from the block/canvas,
- To make the difference between a user exit and Forms exit so the trigger can sort it out.
Any clue will be much appreciated.

Let me put it clearer:
Actually, I do have my 'commit_form and exit that block codes' in my button trigger.
But the user can also exit from the block/canvas by clicking anywhere on the main canvas (since they are stacked), what I don't want. The post-block trigger is there to prevent him to do so, by raising a form_trigger_failure (since I can't use a go_block to go back to my canvas).
That means I don't use 'commit_form' in my post-block trigger.
By the way, what's the difference between 'commit_form' and 'FORMS_DDL('commit')' again ?

How to exit from Enter-Query mode

Hi
I am not being able to exit from the Enter-Query mode if the result set is not returned.
I tried to exit using ABORT_QUERY, exit_form( as we used to do in earlier version) and CTRL+Q. Nothing seems to work and I have to kill the form
This seems to be an easy topic, but I need your help.
Thanks in advance

Blocking some fields from entering in summary block in enter query mode

Hi ,
I have a data block where in some fileds have to be dynamically allowed to enter and some are not based on
a particular condition. The problem is whenever the forms enters enter query mode, all the fileds in the block are updateble. Even maually I tried to set/unset the property in forms using set_item_property, but the enter query mode was trying to overiride it and making updateble.
Please suggest a solution for this.
Thanks in advance.
Thanks,
Lohith

Try the below code
IF :SYSTEM.MODE='ENTER-QUERY' THEN
SET_BLOCK_PROPERTY('BLOCKNAME',INSERT_ALLOWED,PROPERTY_TRUE);
SET_BLOCK_PROPERTY('BLOCKNAME',UPDATE_ALLOWED,PROPERTY_TRUE);
SET_BLOCK_PROPERTY('BLOCKNAME',DELETE_ALLOWED,PROPERTY_TRUE);
you can set the item here too by using the below code
SET_ITEM_PROPERTY('BLOCK.ITEM_NAME',INSERT_ALLOWED,PROPERTY_TRUE);
SET_ITEM_PROPERTY('BLOCK.ITEM_NAME',UPDATE_ALLOWED,PROPERTY_TRUE);Regards

How to display LOV on web in ENTER-QUERY mode with form or block query only.

Hello all
How can I display lov automatic on the web in from enter-query
mode in form or block query only mode.
thankx

If I understand correctly your explanation, your called form
fails to activate the LOV in enter-query mode when it is deployed
and test on the browser.
So lets proceeed like this, to make it work in all environments,
let us programetically activate the LOV.
HOW?
In the called form, write in the WHEN-NEW-ITEM-INSTANCE TRIGGER
at block level (if have more than one LOV)
IF :SYSTEM.MODE = 'ENTER-QUERY' THEN
IF get_item_property(:system.cursor_item,lov_name) IN ('YOUR
LOV1', 'LOV2' etc) THEN
IF SHOW_LOV(get_item_property(:system.cursor_item,lov_name))
THEN
NULL;
END IF;
END IF;
END IF;
The above code maybe tweak to suite your need and condition.
This way, we explicitly make the LOV appear in ENTER-QUERY mode
whenever the user clicks on an item with an attached LOV.
Hope this helps.

Block based on view ,enter query

Hi,
I have a block based on a view.One column of the view is
substr(f_gt_marks(tcs23.idu_nr_dossr),1,128).
When I enter 'PAPER%' for the above column and press execute query i get:
PAPER
PAPER1PAPER2
When the form is in enter query mode and when I enter 'PAPER' and press execute query I get FRM 40301 query caused no rows to be retrieved.
I want only paper to be retrieved.The form works only if I append % to the search criteria.
Can you please advise me.
I am working on forms 9i.
Thanks and Regards

Try to debug for form, and get the SQL Statement that is being executed, see if it's doing anything out of the ordinary and try to run in SQL*Plus and see the result.
I think your SQL is trying use the SUBSTR function on the value you enter in ENTER-QUERY mode.
SUBSTR(f_gt_marks('PAPER'),1,128)Anyway, best for you to see what the form's SQL statement is when issuing the query.

Enter Query Mode with Block Based on Stored Procedure

How can I get the ENTER QUERY mode to work when the data block is based on a stored procedure?

Thank you for your review.
Because the package is long, I stripped most of it out, but left the basics. After I stripped out the code, I ran the new code under a new user. Under the new user I built I new form, tested it, and I still cannot use the ENTER QUERY mode to retrieve the correct record. Query always returns the first record. I have included table structure and 3 test records.

is there any way to retrieve photos from a 5c that has gone into recovery mode?

No, by the time its in recovery mode it's too late. The contents of the phone are gone. Did enable any of the ways that Apple provides to back up photos?
Backup the phone to your computer
Automatic daily iPhone backup to iCloud
enable Photo Stream
Copy photos to your computer using a USB cable and a compatible photo management utility on your computer
Enable Photo Sharing
Enable Photo Library backup
OR any of the 3rd party photo management solutions, such as Google Picasa, Google+, Facebook, Shutterfly?
OR any of the cloud sharing services such as box.com or dropbox?
If you have set up any one of these your photos can be retrieved from it.

Prevent interpretation of special characters in enter-query mode

My problem goes as follows:
- forms version: Forms [32 Bit] Version 6.0.8.10.3 (Production)
- non-database item block.X, char
- block.X is filled in post-query trigger. The post-query logic cannot be integrated in a view because it uses procedures, and usage of a pipelined function + view is currently not allowed due to "internal restrictions". Put simply: all logic to fill the field must remain in the post-query trigger
- user wants the field to be queryable. This is achieved by storing the entered criterium in a variable in the pre-query trigger, and using it in the post-query trigger to exclude records. E.g.
pre-query ==> help_block.query_X := block.X;
post-query ==> if help_block.query_X is not null and block.X is null or not block.X like help_block.query then raise form_trigger_failure; end if;
- this works fine for "regular" search strings. However:
- whenever the search string starts with <, <=, >, >=, !, forms seems to interpret the leading characters before doing anything else. During pre-query, block.X is null, and as soon as I use it in pl/sql, I get FRM-40831: Truncation Occured: value too long for field. E.g.
user puts the following in block.X ==> '<X', so he wants to search for records with value '<X' (text; not 'smaller than ...')
pre-query => msg.show(block.X) ==> appears to be empty/null, but right after the message, I get FRM-40831 Truncation Occured: value too long for field ...
This only happens if < is the first non-space character in the search string.
Does anyone know of a way to prevent oracle from interpreting the <, <=, ... characters entered in enter-query mode?

I'm sorry for not making myself clear; I'll give it another go:
The problem is that, if I enter '<abc' in a form field in enter-query mode (so during creation of the "example record"), forms immediately interprets the < as 'smaller than' and does some obscure things with it (my guess: converting to a where clause, but since I'm using a non db field, this actually does nothing), and finishes by erasing the field contents (in the example record). In the pre-query trigger, I can no longer get the '<abc' and store it. I want one of the following:
- prevent forms from interpreting the '<' in front (same thing happens for !=, <=, >=, =, ...)
or
- capture the entered string ('<abc') before forms reacts to the '<' in front

FRM-40200 and FRM-40501 in Enter-Query-Mode

Some strange behaviour in Enter-Query-Mode:
Although the help states
About Designing Forms for Querying+
+.. To make a "query-only" block, set Query Allowed to Yes and Delete Allowed, Insert Allowed, and Update Allowed to No. ..+
I get FRM-40200: Field is protected against update.
System.Mode says, we are currently in ENTER-QUERY.
Setting insert- and update-allowed to TRUE, I get
FRM-40501: ORACLE error: unable to reserve record for update or delete.
The entered character flashes and is erased immediately.
Any ideas?
Forms 10gR2
Items are base table, all transactional properties aund query_allowed are true, query_length is ok.
2 Things that happen before the initiation of the enter-query-mode:
. data-source is changed to another view; column names are ok.
. all block-items are disabled and not navigable at start-up of form and re-enabled and made navigable before entering the block.
The values of block and item-properties mentioned above are take at WHEN-NEW-ITEM-INSTANCE and no further trigger fire.

I think you are not meaning just the KEY-ENTQRY-Trigger, that to easy
IF INSTR(:SYSTEM.TRIGGER_BLOCK, '_DETAIL') = 0
+ AND :SYSTEM.TRIGGER_BLOCK NOT IN ('VZG_KOPF','KONTROLL','BUTTONS','TEMP')+
THEN
+ ENTER_QUERY;+
END IF;
.. but the rest is a lil bit, let's call it bulky; including pll and db-packageges.
I hoped to get a clue, if somebody has a similar expeience, in what direction to search. It's strange.
And, as I noticed today, it's not a problem of all forms of the app. Not even of all the forms called from the same "environment" (same globals, same menu-form from which they are opened). To me it looks like Enter-Query does not work in the forms where I switch the block-data-source from a view to a globally temporary table. That (this switching) is not a new feature and Enter-Query worked in the past. Althoug we had some changes in the temp tables in the last weeks there are no problems in querying the data in the forms. Recompilation of pll and fmb, no improvement. And either Enter-Query woks in a form or it does not.
