What is the error message/ number you are seeing? If you run "select name from tblperson order by name" do you still get an error?

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

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 ?

Order of numeric string of database column

I have database column that has varchar2 type. I tried to sort it in order but It would not work. It behaves like this.
1 10 11 15 2 20 3 30....
What I want is this
1 2 3 10 11 15 20 30 ....
I tried format mask but it does not help.
Please help.

written before the post immediately above
I'm not sure what you mean by that. It's an oracle function, so check the docs for your version to see if it's available. Otherwise:
CREATE OR REPLACE FUNCTION isnum(p IN VARCHAR2) RETURN VARCHAR2 IS
x NUMBER;
BEGIN
x := To_Number(p);
RETURN 'Y';
EXCEPTION
WHEN Value_Error THEN
RETURN 'N';
END;
WITH data AS(
SELECT 'a' AS col1 FROM dual UNION ALL
SELECT '11' AS col1 FROM dual UNION ALL
SELECT 'd' AS col1 FROM dual UNION ALL
SELECT '1' AS col1 FROM dual UNION ALL
SELECT '2' AS col1 FROM dual UNION ALL
SELECT 'b' AS col1 FROM dual UNION ALL
SELECT '10' AS col1 FROM dual UNION ALL
SELECT '12' AS col1 FROM dual
SELECT col1
FROM data
ORDER BY
CASE isnum(col1) WHEN 'Y' THEN 'b' ELSE 'a' END,
CASE isnum(col1) WHEN 'Y' THEN To_Number(col1) END,
CASE isnum(col1) WHEN 'N' THEN col1 END
;

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

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?

set_block_property('blockname',default_where,'give neccessery where condition')

Checking whether data exists in a BLOB type database column in Forms 6i

I am developing an application regarding inventory of a plant's spare parts. I am storing photo (.bmp) of spares in the database in a column of BLOB type. Once user punches spare's code, form displays spares data on screen using EXECUTE_QUERY. At this stage I want to check whether picture (.bmp) data was found in BLOB type database column or not. I want to take action accordingly. How to check this. If it would be a numeric column, I would have checked NULL but NULL does not work with BLOB type coloumns.
Pl. help.
Thanks in anticipation.

Did you look in the database documentation? The DBMS_LOB package has the method you need: getlength().
This was more of a database question than a Forms question, so you'd probably have more luck with these types of questions on one of the other forums, like the database or SQL forums.

Set the value of a non database field in forms

hai friends ,
Have been struggling a lot with the problem now . Could anyone suggest me how to go about it.
I want to set the value of a field in a form . I know the function set_value and set_value_as_(data type ) does the work . But then is there any constraint on the position where it is called.
My requirement is on querying a form the data from the tables mut be populated( which the portal handles) and I want to populate the non database bound fields with certain values.
Could any one help me out with this ..
null

I need to set value to one of the object attributes if that attribute is blank.This is some kind of a default value that you want, then? If so then just take care of that when you output it. Use <c:if>, and if the attribute is blank then output the default value, otherwise output the attribute.
Or have the servlet that created that request attribute take care of that requirement.

Deleting Column using Form Settings issue

I have a problem deleting a column from the Sale Order Enty screen. I added the Bar Code column to the Sales Order Entry grid to 5 users using Forms Settings. I decided to delete it from all 5 users, so I went back to Forms Settings and deleted the column. Actually, I checked the Visable check box to have the Br Code column displayed and then I unchecked the Visable check box on the Form Settings form.
The problem I am experiencing is that one of the 5 users, I delete the column, and when the user logs back into the system again, the column is back, and I have to delete it again. This happens each time the user logs out and then back in. Has anyone else experienced this problem? And if so, how did you resolve it?
Thanks in advance!!
Dana

This user's profile must have some problems. One way to check is log this user in another workstation to see. Make sure only one session for this user whenever you change and save form settings for the user.
Thanks,

hi
How to get up and running with WebUtil 1.06 included with Oracle Developer Suite 10.1.2.0.2 on a win32 platform
Solution
Assuming a fresh "Complete" install of Oracle Developer Suite 10.1.2.0.2,
here are steps to get a small test form running, using WebUtil 1.06.
Note: Oracle_Home is used as an alias for your real oDS ORACLE_HOME.
Feel free to copy this note to a text editor, and do a global find/replace on
Oracle_Home with your actual value (no trailing slash). Then it is easy to
copy/paste actual commands to be executed from the note copy.
1) Download http://prdownloads.sourceforge.net/jacob-project/jacob_18.zip
and extract to a temporary staging area. Do not attempt to use 1.7 or 1.9.
2) Copy or move jacob.jar and jacob.dll
C:\webutile is the folder where you extracted Jacob, and will end in ...\jacob_18
cd C:\webutile
copy jacob.jar Oracle_Home\forms\java\.
copy jacob.dll Oracle_Home\forms\webutil\.
The Jacob staging area is no longer needed, and may be deleted.
3) Sign frmwebutil.jar and jacob.jar
Open a DOS command prompt.
Add Oracle_Home\jdk\bin to the PATH:
set PATH=Oracle_Home\jdk\bin;%PATH%
Sign the files, and check the output for success:
Oracle_Home\forms\webutil\sign_webutil Oracle_Home\forms\java\frmwebutil.jar
Oracle_Home\forms\webutil\sign_webutil Oracle_Home\forms\java\jacob.jar
4) If you already have a schema in your RDBMS which contains the WebUtil stored code,
you may skip this step. Otherwise,
Create a schema to hold the WebUtil stored code, and privileges needed to
connect and create a stored package. Schema name "WEBUTIL" is recommended
for no reason other than consistency over the user base.
Open Oracle_Home\forms\create_webutil_db.sql in a text editor, and delete or comment
out the EXIT statement, to be able to see whether the objects were created witout
errors.
Start SQL*Plus as SYSTEM, and issue:
CREATE USER webutil IDENTIFIED BY [password]
DEFAULT TABLESPACE users
TEMPORARY TABLESPACE temp;
GRANT CONNECT, CREATE PROCEDURE, CREATE PUBLIC SYNONYM TO webutil;
CONNECT webutil/webutil@rcci
@Oracle_Home\forms\create_webutil_db.sql
-- Inspect SQL*Plus output for errors, and then
CREATE PUBLIC SYNONYM webutil_db FOR webutil.webutil_db;
Reconnect as SYSTEM, and issue:
grant execute on webutil_db to public;
5) Modify Oracle_Home\forms\server\default.env, and append Oracle_Home\jdk\jre\lib\rt.jar
to the CLASSPATH entry.
6) Modify Oracle_Home\forms\server\formsweb.cfg insde [default] add :
archive_jini=frmall_jinit.jar,frmwebutil.jar,jacob.jar
archive=frmall.jar
also add :
[webutil]
WebUtilLogging=off
WebUtilLoggingDetail=normal
WebUtilErrorMode=Alert
WebUtilDispatchMonitorInterval=5
WebUtilTrustInternal=true
WebUtilMaxTransferSize=16384
baseHTMLjinitiator=webutiljini.htm
baseHTMLjpi=webutiljpi.htm
baseHTML=webutilbase.htm
archive_jini=frmall_jinit.jar
WebUtilArchive=frmwebutil.jar,jacob.jar,f90all.jar
archive=frmwebutil.jar,f90all.jar
lookAndFeel=oracle
7) Modify Oracle_Home\forms\server\webutil.cfg and add :
transfer.database.enabled=TRUE
transfer.appsrv.enabled=TRUE
8) Start the OC4J instance
9) Start Forms Builder and connect to a schema in the RDBMS used in step (4).
Open webutil.pll, do a "Compile ALL" (shift-Control-K), and generate to PLX (Control-T).
It is important to generate the PLX, to avoid the FRM-40039 discussed in Note 303682.1
If the PLX is not generated, the Webutil.pll library would have to be attached with
full path information to all forms wishing to use WebUtil. This is NOT recommended.
10) Create a new FMB.
Open webutil.olb, and Subclass (not Copy) the Webutil object to the form.
There is no need to Subclass the WebutilConfig object.
Attach the Webutil.pll Library, and remove the path.
Add an ON-LOGON trigger with the code
NULL;
to avoid having to connect to an RDBMS (optional).
Create a new button on a new canvas, with the code
show_webutil_information (TRUE);
in a WHEN-BUTTON-PRESSED trigger.
Compile the FMB to FMX, after doing a Compile-All (Shift-Control-K).
11) Under Edit->Preferences->Runtime in Forms Builder, click on "Reset to Default" if
the "Application Server URL" is empty.
Then append "?config=webutil" at the end, so you end up with a URL of the form
http://server:port/forms/frmservlet?config=webutil
12) Run your form.

Query Non Database items in form

I need to be able to query non database items in the form.

Hi,
Yes you can do this. You have to create control items all of them have same data type and lenght as table's. then you can issue select statement. eg.,
select field1, field2
into :item1, :item2
from table_name;
Hope this helps

Create database table using Forms Developer 6/6i without using SQL*Plus

hello there,
I need help in creating tables in Oracle using Forms Developer 6/6i without using SQL*Plus interface.

email: [email protected]

please use Forms_ddl package to create a table dynamically
from the Developer6/6i.
you can check the success or failure by using the
form_success builtin.
if u want to avoid using the Forms_ddl package
use stored procedure or create a sql querry record group.

Problem Ordering/Limiting LOV by non-SELECTed column

When I try to create a dynamic LOV using the following SQL query:
select reportname d, pageno r
from dms_occurances
order by occurances desc
limit 2
I get the following error:
LOV query is invalid, a display and a return value are needed, the column names need to be different. If your query contains an in-line query, the first FROM clause in the SQL statement must not belong to the in-line query.
This makes absolutely no sense to me, as the query appears valid. What am I doing wrong here? I'm trying to create a LOV for the two most popular report pages viewed in the application.

Hi
I am not sure that LIMIT would work with Oracle... you may need to use ROWNUM instead:
select *
from
(select reportname d, pageno r
from dms_occurances
order by occurances desc
where rownum <= 2
Regarding the message... I think it is a "standard" message, which is displayed even if the problem is not related to the columns number/names. :o/
