How to re-query changed record in multi-row block after update in a called form
Hi,
I have a form that I use to perform searches, which is a multi-record block.
The user can navigate to a record, press a button on call another form which provides
more detail, and allows update of the record.
If the user changes it, and returns to the original search form, how can I re-query the
changed record to update the fields on the search form.
Is there a way other than to re-query the
whole block - a built-in to just update on record if it's changed on the database.
If not, can I use globals to pass back the data (since only a few fields are updatable),
and change the record without effecting its forms status.
Many thanks
Bernie
BD,
I haven't managed to look at a solution yet, but the block is a large multi-row block,
with an ORDER BY, and since it can return a large number of records, there is a short
delay. I was hoping there was a way of just
re-querying the one record, which was displayed
in the second form for update.
I'll give the query a go, or might try and pass back some globals with the update values.
By the way, DML Return Value is an excellent feature, but only works against Oracle 8.
It basiclly adds the RETURNING clause to any DML statement (see SQL manual), so that if
a trigger changes/adds values you didn't provide, it will return them back to you
so the values in your form are correct.
I use a trigger on the DB to populate history fields (create/update,who/when) and
the PK sequence. Using this feature, those values are returned to the block and displayed.
Regards
Bernie

Dynamically Changing Labels for Multi Row Block Buttons
Forms [32 Bit] Version 9.0.4.1.0 (Production)
Oracle Database 10g Enterprise Edition Release 10.2.0.5.0 - 64bit Production
On my local: Windows 7 OS
I am having a difficult time in doing the following in forms, and not sure if it can be done?
I have a multi row block,based on DB table, which displays filename and another column from the table.
It also has a push button on each row, which opens and displays the physical file from its source, when clicked. The filename thus can have 3 diff statuses depending on its sources and accordingly corresponding button should display appropriate label:
a) View Image (its is in content server and successfully imaged. In this case I display the file in the browser, from the content server, when the button is clicked)
b) View File (Display the file from file system)
c) View Error (Display imaging error message from the table, as file failed to make it to the imaging server)
I have this logic currently coded in the post query trigger, at the block level, and tried using set_item_property(button_id, label, <button_lable>), where I programmatically set the button lable, based on the file status (imaged, not imaged or has error) in that row. This wroks well, only if all the files in the multi row block have the same status. If each of them have diff statuses, then only last processed files's status gets reflected into the button label. For eg: The file in the first row of the block is imaged, and one in the second row has an imaging error. The button label for the first row should say 'View Image' and button for the second row should say 'View Error'. But now buttons for both the rows display 'View Error', as thats what got processed last!
I __can not use set_item_instance property for 'label'__ (which lets us dynamically change the label on the push buttons).
Is there any way to do this for ORacle forms? I am now playing with having 3 diff button items in that block, laying them on top of each other and showing only those that are appropriate and hiding the others... But I am not sure it is going to give me what I need? I think I am going to end up facing the same issues as in above case!!
Any expert advice is highly appreciated.
Thanks in advance for your time:

How can I handle data in a multi row block?
Hi all,
I have a form which contain a multi row block.
I put data in that block. Suppose that in the second column of
that block data no changes.I want to fill only the first cell of
the column and all the cells below first cell ( header) inherits
that value.
Example :
Block1
ITEM1 ITEM2
rec1 1 1999
rec2 2
rec3 3
When I insert in the table rec2 I want :
INSERT INTO(col1,col2) VALUES)(2,1999)!!!.
Best Regards !

Mr. Vali,
I suppose you want to enter ITEM2 value only in first record and
duplicate that value in subsequent records automatically. There
are couple of methods to accomplish this and the following is one
of them:
Add this code in WHEN-NEW-RECORD-INSTANCE trigger for block1.
IF :SYSTEM.RECORD_STATUS ='NEW' AND :SYSTEM.CURSOR_RECORD > 1
THEN
IF :ITEM2 IS NULL THEN
GO_ITEM('ITEM2');
DUPLICATE_ITEM;
GO_ITEM('ITEM1');
END IF;
END IF;
good luck

HOW TO MAKE CHECK BOXES EXCLUSIVE IN MULTI ROW BLOCK
Hi,
I have a multi row block with one item as check box.It is
required that at a time only one record can be marked as
selected through this item. If user marks a record as selected
the previous selected record should be marked as deselected.
How i can make these check boxes mutually exclusive ?
can anybody help me?

Hi
The check box can not be mutually exclusive.
This is a basic functionality.
You convert this item type into radio button.
It will satisfy your requirements.

Overflow-field in multi-rows block
Hi!
How can i realize overflow-field in multi-rows block.
I place overflow fields in the footer area of block
and get value use ${uix.current['Description']} - but no have results.
Use javascript to set value of overflow-field?
thanksAndreas,
I was most intrigued by your offered solution, so I created a test case. Unfortunately, this solution gives inconsistent results. Here was my test case:
1. Table: Planets
Columns: 3 (PL_ID, Name, Description
2. Added nine entries for all 8 planets and one record for Pluto (sorry, grew up with this being classified as a planet! :) )
3. Created very basic form to display all 3 columns in Tabular (Multi-Record) format and displayed 5 rows.
4. Created button in a Control Block to display Cursor_Record, Trigger_Record and Top_Record
- Set Mouse & Keyboard navigate to NO
Ran Form and navigated to each row and clicked on button. The following was my results:
>
Row 1: Cursor Rec: 1, Trig Rec: 1, Top Rec: 1
Row 2: Cursor Rec: 2, Trig Rec: 2, Top Rec: 1
Row 3: Cursor Rec: 3, Trig Rec: 3, Top Rec: 1
Row 4: Cursor Rec: 4, Trig Rec: 4, Top Rec: 1
Row 5: Cursor Rec: 5, Trig Rec: 5, Top Rec: 1
Row 6: Cursor Rec: 6, Trig Rec: 6, Top Rec: 2
Row 7: Cursor Rec: 7, Trig Rec: 7, Top Rec: 3
Row 8: Cursor Rec: 8, Trig Rec: 8, Top Rec: 4
Row 9: Cursor Rec: 9, Trig Rec: 9, Top Rec: 5
Row 10: Cursor Rec: 10, Trig Rec: 10, Top Rec: 6 - New Record - NULL values
- Navigated back to Row 6: Cursor Rec: 6, Trig Rec: 6, Top Rec: 5 (however - visually in the screen Row 6 was the 2nd row of the 5 rows displayed.
- Navigated back to Row 3: Cursor Rec: 3, Trig Rec: 3, Top Rec: 3 (however - visually in the screen Row 3 was the 1st row of the 5 rows displayed.
>
Based on these results, the option to use the GET_BLOCK_PROPERT('BLOCK_NAME',TOP_RECORD) won't work either. :-( Unforntunately, displaying the MCHAR field in a static location or using Java (though hardest) are still the best solutions.

How can we get changed records in delta in case of numeric pointer
Deall All,
Thanks to all of you gurus i have been able to Get delta update for my query.
There is one last issue how can i include changes records in my delta update when i am using numeric pointer for data selection.
or
It can only be doen by time stamp.
can you explain me details of using time stamp.
Thanks & regards,
Gaurav SoodDear Gaurav,
Here we have three options for delta updation:
Time Stamp: If we want to update change in the records with respect to the time interval then this option is selected.
Calend. Day: If we want to update change in the records with respect to day to day basis then this option is selected.
Numeric Pointer: If we want to update in case of record which is completely new with respect to Field name then we use this option.
And we have got some settings like:
Safety Interval upper limit:
This field is used by Data Sources that determine their delta generically using a repetitively-increasing field in the extract structure.
The field contains the discrepancy between the current maximum when the delta or delta init extraction took place and the data that has actually been read.
Leaving the value blank increases the risk that the system could not extract records arising during extraction.
Example: A time stamp is used to determine the delta. The time stamp that was last read is 12:00:00. The next delta extraction begins at 12:30:00. In this case, the selection interval is 12:00:00 to 12:30:00. At the end of extraction, the pointer is set to 12:30:00.
A record - for example, a document- is created at 12:25 but not saved until 12:35. It is not contained in the extracted data but, because of its time stamp, is not extracted the next time either.
For this reason, the safety margin between read and transferred data must always be larger than the maximum length of time that it takes to create a record for this DataSource (with a time stamp delta), or it must display an interval that is sufficiently large (for determining delta using a serial number).
Safety Interval Lower Limit
This field contains the value taken from the highest value of the previous delta extraction to determine the lowest value of the time stamp for the next delta extraction.
For example: A time stamp is used to determine a delta. The extracted data is master data: The system only transfers after-images that overwrite the status in the BW. Therefore, a record can be extracted into the BW for such data without any problems.
Taking this into account, the current time stamp can always be used as the upper limit when extracting: The lower limit of the next extraction is not seamlessly joined to the upper limit of the last extraction. Instead, its value is the same as this upper limit minus a safety margin. This safety margin needs to be big enough to contain all values in the extraction which already had a time stamp when the last extraction was carried out but which were not read. Not surprisingly, records can be transferred twice. However, for the reasons above, this is unavoidable.
Data Source Is Real-Time Enabled
The 'real time enabled' indicator determines whether a delta-enabled Data Source can be used as a supplier of data for a real-time daemon.
And there are two options provided like
1) New Status for changed records:
If you select this option each record to be loaded delivers the new status for the key figures and characteristics. DataSources with this delta type can write to ODS objects or master data tables.
2) Additive Delta:
The key figures for extracted data are added up in BW. Data Sources with this delta type can supply data to ODS objects and Info Cubes.
Hope this helps u..

How we can load change record in cube.
Hi,
How we can load change record in cube, (delta)
i need step by step in sap BI 7.0.Hi Nitin
I hope you are asking about delta loads, if your datasource supports deltas then you can do only changed records from source to cube. To see the details goto ROOSOURCE table in ECC and find.
For further help search in SDN and help.sap.com, you can find n number of postiings about the same.

How to calculate total in multi-row block
How can I calculate and display the total amount in a multi-row
block that records are not yet save into database?

Hi,
I worked with similar type of requirement. If you are
working with Forms5.0 there is a new property of formula/summary
in property palette of text item. In the same block or in
control block create non database item( It's non base table item
in forms4.5). In it's property palette give the data type as
number and set the source item name and set summary property.(
opetions are max,min,sum etc available). This value will change
when you navigate from the source item( I mean after validation).
I think this is informative.

Dynamic visual attributes/multi-row blocks
We're using Headstart, Des2k V6.0.3.8. If you set preference CURREC = multi record block, you get the current record visual attribute (cg$current_record) attached to all displayed items in multi-row blocks. From the Headstart object library, these items also inherit a visual attribute of qms$item_font.
At runtime, Headstart code is invoked from the block's post-query trigger - this code dynamically assigns a readonly visual attribute to all items that are insert only, or the qms$item_font va to items that are update only. (Incidentally, it seems a bit strange that no va is assigned to items that are neither insertable nor updateable).
Assigning the va in this way seems to override the current record va for these items, which looks a little strange at runtime. I would prefer to see the current record va overriding the readonly/item_font va. In a future Headstart release, it would be nice if this functionality was configurable, but in the meantime can you suggest the easiest way of making this change to the Headstart code? I think it will be necessary to specifically set the va to stnd/readonly/current record in the when-new-record-instance trigger, & reset it on the post-record trigger. Once va's are being set dynamically, the current record attribute is pretty useless in multi-row blocks.
Incidentally - we've also changed the behaviour of va's in query mode processing. We wanted the query mode va to override the current record va; qms$record.highlight_items wasn't setting the selected va unless items have a current record attribute of DEFAULT. We wanted query mode to look the same regardless how many rows are in the block; it also looked a little odd in a multi-row block with overflow items, where the overflow items were being highlighted but the rest of the block wasn't. It would be nice if this was also a configurable option.Cheryl,
Good point! It does look a bit odd. I'll take this into consideration for HSD6i.
To customize your app, try the following.
Copy qms$event_data_block from qmsevh50.pll to your application library.
Copy procedure set_nav_items_exg_record from the qms$record package in qmslib50.pll to your application library -AND GIVE IT A NEW NAME- like set_nav_items_custom.
Change your copy of qms$event_data_block to call this new procedure in the post-query event.
Modify set_nav_items_custom as follows.

Multi row block record_group or cursor?
I've done a lot of research on the Forms OTN forum and can't find a solution to this problem. I'll continue to research until an answer is posted to this thread. I've used the forms forums and Metalink for years and they've been a great help.
My problem -
I have a multi-row block built off a view. Each row has a check box. The canvas also has a button. When the button is pressed, each record checked will be processed. The problem is, I need to sort the data selected (checked) before it's processed. To complicate matters, the sort criteria is not in the view. My plan was to build a cursor off the block, but I'm having problems populating due to the multi-row aspect.. I also tried building a record_group but again ran into complications with it being multi-row. I'm not sure which method to use since I haven't found a clear-cut solution.
btw - using 10gR2.
TIA,
abcAB, you're sure not very clear on this.
Aweiden has the correct suggestion: Create a PL/SQL table in the form, rather than a record group.
Here are the steps I would follow:
1. User queries and displays the data, and then checks some checkboxes. Do not use a when-checkbox-changed trigger, since they can check, then un-check boxes.
2. When user presses the process button, loop through the block as Aweiden has done above. However, I would call a procedure from within the loop to look up the values from the Mel_Item table. Store the values returned from the procedure within your pl/sql table, adding one row to the table for each row in your block that was checked.
As a side note, how difficult is it to join the Mel_Item table with your view when you query the block? You could store those sort values from Mel_Item along with the data from the view.
3. Once you are done processing the data block loop, sort the pl/sql table. (Maybe I can find the code lying around here somewhere, but a table sort like that can be coded in maybe 20 lines).
I am not sure, but are you saying above ("...insert each row into another table (other information is different so its not duplicate rows entirely)...") that you are inserting the data from the user-checked rows into a database table? That is certainly easier to do than writing your own sort, I guess.
4. After the pl/sql table is sorted, loop through it one more time, processing the data in the required sequence.
Actually, pl/sql table processing is quite fast. You don't really need to sort the rows. All you need do is to step through the table checking for the first row to process (by finding the lowest value of the sort items). Process that row's data, then remove (delete) it from the table, then repeat the process until you have processed and removed every row from the array. I believe I would use this method rather than trying to sort the pl/sql table, OR inserting into a database table.

Multi-row block with many image-java-beans
Hi, I want to create a multi-row block based on a table, e.g. emp with 5 records.
Then I want to add 5 java-bean images in the same block. Now I want to read from the db-table emp the blob-column with the image of the corresponding empno. Is this possible? How can I do this? Can someone give me a sample for this?

How do I get my information back on my phone after updating itunes
how do I get my information back on my phone after updating I Tunes. I up dated it this morning and when it was complete, all my contacts and my pics and my screen savers and sounds were from my daughters phone. I can not locate any of my information on my phone?
All iTunes content they you have selected to be transferred to your existing iPhone - music/video/podcasts including 3rd party apps remain in your iTunes library on your computer. Photos transferred to your existing iPhone via the iTunes sync process also remain on your computer.
If you are syncing contact info and calendar events with the Address Book and iCal on your Mac, this data also remains on your computer.
You can sync multiple iPods and/or iPhones with the same iTunes library and iTunes account with each device having its own sync settings.
When you connect a new iPhone to iTunes on your computer, you will be prompted to transfer the backup for another iPhone that has been synced with iTunes. After the backup for your existing iPhone is transferred to your new iPhone, this must be followed by a sync to transfer your selected iTunes content including 3rd party apps and any photos on your computer selected to be transferred to your iPhone. You select sync contacts with the Address Book and calendar events with iCal under the Info tab for your new iPhone sync preferences and this data will be transferred to your new iPhone. -

Microsoft optical mice and wheel scrolling in multi-row block
Hi.
One part of our form is a multi-row block. It has a scroll bar and upto this point you can scroll using the wheel when your mouse is on the scroll bar or if the pointer is anywhere within the multi-row block, you can use the wheel to scroll. This works for logitech ball and optical mice, ibm ball mice and even microsoft ball mice. All of them have the wheel. We do find a problem with microsoft optical mice whether its the explorer or optical brand. The wheel mouse works when the pointer is on the scroll bar but it does not scroll if the pointer is within the multi-row block. I have spoken with Oracle and of course they say its microsofts problem. Has anyone come across this? I have contacted microsoft but no word as yet.
Thank you,
JaymeForms has no support for the Wheel Scrolling action - if it works at all it's because the Mouse driver is clever enough to work out when it is on a ScrollBar and send the relevant Windows Events. You may find it also works in Multi-line text items.
