I want to ask what's wrong with my multi-record block.
When i click a node on my tree, it should display the records on it. For example, my root node is Sections, the parents are 1st sem and 2nd sem. In each sections in 1st sem, whenever i click a child node, it should display on display items. I have set its number of items displayed to 9. Since each sections have 9 subjects. The problem when i run it is that it displays many rows.

In one of my form , there is some code "next_record;" in the key-next-item trigger of one field.Here before going to next record, it is executing the WHEN-VALIDATE-TRIGGER of all the items in that record.Is it the default behavior of oracle forms?Can we override this?

I have a list block of two fields item_name, item_price. User can enter as many item`s as she/he wants. But, before saving the record system should calculate the total and give error if sum is grater then or less than 100.

I have already done a hierarchy tree. Now I'd like to make it bind to text items. When i click a node, it should automatically be bound to text items.
My tree is about sections of students, now when i click a specific section to view its corresponding subjects it would be displayed on text items.
For example:
+Sections
+First Semester
+LM2
+LM3
+Second Semester
+LM4
+LM5
When i would click on LM2 node, its subjects should appear immediately.

I have form with master detail relation ship (invoicing form) the detail block is tabular, displaying upto 7 records...
Now my clients wants to show the serial number along with each record while feeding the data (this includes when insert, editing, deleting / clearing records) he wants to see the serial number as in MS access / MS techniques.
I tried to use the system variable to use :system.cursor_record; but this dose not works.(in insert/edit/delete/clear record)

I am working on forms 6i. I have one data block based on table EMP.
Datablock-A: Empno, Ename, Sal
I have FIND Screen: Empno, Ename, FIND Button.
I can search the data through FIND Screen and populate data in Datablock A.
I am using below logic to search data through FIND Screen.
When-Button-Pressed(FIND Button): calling 'EXECUTE_QUERY'.
In Pre-query trigger of DatablockA:
copy(:FIND.EMPNO,'BLOCKA.EMPNO');
copy(:FIND.ENAME,'BLOCKA.ENAME');
It's working fine. But below case is failing.
Let us say, if i enter empno 10 (which is not there in database) in FIND Screen --> press FIND Button, it's showing up 'QUERY CAUSED NO RECORDS', Till this point it's working fine;. But after this, if i press CTR+F11 in block A, it's not pulling records. only this case it's not pulling records.
But if i enter something else in FIND Screen, if it returns any data, then if i press CTR+F11,it's pulling all records.
why it's failing to pull records if i try to query data in first case only.

we are generating Entity beans at java appication. where application is connecting to DB and copy Table structure in Java class file. when this process start, oracle process takes 100% CPU. while there is no wait event at DB level. only queries are fired on oracle sys tables.(user_tables,user_constraints,etc..)
On trial and error based, we have changed this parameter and that java process works fine. how this parameter effect the on oracle system table.

INSERT INTO OT_ACTUAL_ACT(ITEM_CODE,ITEM_NAME,WO,STRUCT)
VALUES ('1001','HEA100X10','300',null);
[Code]...

ITEM_CODEITEM_NAMEWOSTRUCT
1002 HEA100X2230030010
i want all the records
ITEM_CODEITEM_NAMEWOSTRUCT
1002 HEA100X2230030010

I have control block. In which user enters two values. Next is data block in which two items have property 'copy value from item' set to 'control block.item1' and 'control block.item2' resp. If thees items are made database items then in execute query will they be sent as parameters in addition to default where clause? if I check last query then query does not hv these parameters but the records returned are already filtered by control block items.

I wonder if there is some tiny technique to trace a duplicity on a block label without committing the records ( Maybe on Validate or new record instance)
I have one procedure to check duplicate but what I remember that there is something very smart provided from oracle to do that.

I have data that the user is modifying on the form and a data block that is supposed to reflect those change (summaries) So I created
TYPE VehicleInfo IS RECORD (Vehicle_Desc ctl_fleet_vehicles.Vehicle_Desc%Type,
Miles timecapture.miles%Type,
Hours TimeCapture.Equipment_hours%Type);
TYPE VehicleTab IS TABLE OF VehicleInfo
INDEX BY BINARY_INTEGER;
VehicleObj VehicleTab;
I fill this up with the correct data, but I would like to be able to use this as a table in the data block (called Vehicle_Summary) In the past I have piped tables into data blocks from the server, but I'm unsure how to use a table I created in forms in the Query Data Source Name of the data block.

While there's numerous QAs about inserting an image into the DB using the Data Block, how does one remove an image? Obviously there's the "UPDATE ... SET X = EMPTY_BLOB();", however, that kills the Data Block/Form's flow, and it doesn't update.
I've tried a few things:
* :CONTROL.IMG1 := NULL; (bad bind variable)
* :CONTROL.IMG1 := EMPTY_BLOB(); (some other error, probably as above)
