No base table multi record block...updation

hello all,
i have a multi record block with two fields order & datetime to capture the time of the order. but this block is not based on any table. and i want to update another table with the datetime based on the order captured.
how to do that...? there may be n number of records coming into the block at a time.
thx in adv.
Kris

the best way is make it as a database block .and palace your insert statement in pre-insert trigger when you are inserting the record and place your update trigger in pre-update trigger u can also place your insert and update statement in back end, "i prefer the backend triggers").I think this is the best way because if you are using the go_block and next_record, that may take lots of time time to traverse record by record.

FETCHING VALUES IN MULTI RECORD BLOCK FROM ANOTHER TABLE USING SELECT STATEMENT.

Hi,
I have one multi record block in which i want to fetch values
(more then one record) from another table using select statement
IN KEY NEXT ITEM.I am getting following error.
ORA-01422: exact fetch returns more than requested number of rows
Thanks in advance.

In your case I see no reason to use non-database block and to try to populate it from a trigger with a query, instead of using the default forms functionality where you can associate the block and the fields with table, create where clause using bind variables and simply use execute_query() build-in to populate the block. The power of the forms is to use their build-in functionality to interact with the database.
Also, you can base your block on a query, not on a table and you dynamically change this query using set_block_property() build-in. You can use any dynamic queries (based on different data sources) and you simply need to control the column's data type, the number of the columns and their aliases. Something like creating inline views as a block data source.
However, you can replace the explicit cursor with implicit one like
go_block('non_db_block_name');
first_record();
FOR v_tab IN (SELECT *
FROM tab
WHERE col_name = :variable)
LOOP
:non_db_block_name.field1 := v_tab.col1;
:non_db_block_name.field2 := v_tab.col2;
next_record();
END LOOP;

Oracle Forms - need to update multi-record block - Help needed asap

Hi,
We are using Oracle apps release 11i - Oracle forms 6i.
I have a field "project_start_date" in project_block in a custom form. There is another multi-record block called role_block in the same custom form and it has a field named start_date. Requirement is when ever I make change in the project_start_date in project_block, that should reflect in role_block.start_date. I tried different means and could update only the very first record of the multi-record block - role_block. I need to update all the records in the role_block with the same project_start_date. Used looping and several other methods. But could not achieve. Any help is really appreciated.
Thanks

Updating a value of a text item in a multi record block based on a change

Hi,
I need to change the value of a text item in a multi record block based on a change to another item's value in the same block.
Suppose there's a text item in a multi record block called dt1 which is of type date, which is changed in a particular record. I want to change the values of the another item in the same multi record block, for all other records by running a loop through all the records in multi record block. I dont want to do it on the press of a button, it should do automatically on change. Help me resolve this issue.

In an Multi Record Block last previous record should be end dated

Hi all,
can any one help me in this,.....
i a multi record block i need to end date the last previous record,..
Thanks
Raj

Raj,
My guess is that you would want the previous record end-dated even if the user uses a Hot-Key to save the record in addition to using the SAVE button. That being the case, I would add or alter the Pre-Insert trigger on the block to update the find the record that does not have an end-date and update the end_date to SYSDATE. This assumes that there will always only be one record that needs to be end dated. If there are more than one, each record will have the end_date updated. Using your data, you can accomplish this a couple of ways. The first would be to simply update the base table using a simple update statement in an Anonymous Block in the Pre-Insert trigger:
BEGIN
   UPDATE verify_table
      SET enddate = sysdate
    WHERE enddate is null;
END;Second, you could loop through the block in the Form and update any records where the enddate is null.
BEGIN
   GO_ITEM('MYBLOCK.FIRST_ITEM');
   FIRST_RECORD;
   WHILE :system.last_record = 'FALSE' LOOP
       IF :myblock.enddate is null THEN
          enddate := sysdate;
          EXIT;
       ELSE
          NEXT_RECORD;
       END IF;
   END;
END;Hope this helps.

Is it possible to requery only a single row of a multi record block?

Hi,
I have a data block say "Employees". This is a multi record block.
Requirement: Two users are working on the same form (front end). Now the user1 has made change for EMP1 The same is not reflected in the User2 Session. Hence i need to requery the values updated for EMP1
Issue: Since there lots of employees listed in this block. i do not want all the employees details to be required (Block requery). Instead is it possible to requery only a perticular record to be required?
Thanks,
Vidya

I think not possible........
Usually Approach is the data in grid table displays as read only and when user press EDIT button then they can edit one single record in a separate window.
ooh got one idea.......
may be create a save point and rollback to that particular save point ....... i hv never tried it but try it might solves your problem
there is a feature of Clear_form rollback to save point
PROCEDURE CLEAR_FORM
(commit_mode    NUMBER,
   rollback_mode NUMBER);
Parameters
If the end user has made changes to records in the current form or any called form, and those records have not been posted or committed, Form Builder processes the records, following the directions indicated by the argument supplied for the following parameter:
commit_mode     ASK_COMMIT Form Builder prompts the end user to commit the changes during CLEAR_FORM processing.
DO_COMMIT Form Builder validates the changes, performs a commit, and flushes the current form without prompting the end user.
NO_COMMIT Form Builder validates the changes and flushes the current form without performing a commit or prompting the end user.
NO_VALIDATE Form Builder flushes the current form without validating the changes, committing the changes, or prompting the end user.
rollback_mode     TO_SAVEPOINT Form Builder rolls back all uncommitted changes (including posted changes) to the current form's savepoint.
FULL_ROLLBACK Form Builder rolls back all uncommitted changes (including posted changes) which were made during the current Runform session. You cannot specify a FULL_ROLLBACK from a form that is running in post-only mode. (Post-only mode can occur when your form issues a call to another form while unposted records exist in the calling form. To prevent losing the locks issued by the calling form, Form Builder prevents any commit processing in the called form.) Edited by: BaiG on Apr 12, 2010 3:49 PM

Fill a multi record block with a for-loop

Hi
I've got a simple question but I couldn't find a solution yet.
I have a multi record block and behind this i wrote a post-query-trigger with a cursor and a for-loop. Now I try to show each record of the for-loop in the multi record block. The loop works correctly, but the problem is that I only see the last found record of the loop in the first multi record and I'm not able to go to the next multi record when the loop finds more then one record.
I tried to use NEXT_RECORD but then I got the error message "100500: non-ORACLE exception".
May someone help me? Thanks a lot!

What exactly are you trying to do? If you are simply trying to display the result of a query in a Multi-Record Block (MRB), I would recommend basing your block on the query (From Clause Query) or if you are simply displaying the contents of a table or a view in the block, base your MRB on the table or view and let Forms handle displaying the records.
The Post-Query (PQ) trigger will execute for each record displayed in the MRB, which I'm sure is not what you intended. Since the trigger fires for each record, your loop is essentially assigning the value of each row in the cursor to the same row in the MRB.
Hope this helps.

Duplicate item value in a Multi-Record Block

Is there a way to chek duplicate value entered in multi record block?
I have seen some solutions in this forum however nothing has worked for me till now. (using the formula, creating hidden items & creating group etc)
Thanks in advance,

To see if there are any other records in the block with the same value, use Kevin Clark's famous function to trap duplicates. You can find Kevin's function write up here:
Re: checking for same rows in a tabular
From Kevin's post:
Create a field PK_COPY in a control block.
Create program unit function COMPARE to compare two input params returning 1 if they match else 0.
Create a field in the datablock PK_MATCH, calculation property formula, formula COMPARE(:DATA_PK, :PK_COPY)
Create a field in the control block NO_OF_MATCHES, calculation property summary, summary type SUM, summarised
item PK_MATCH.
Also, your control block requires the Single Record property set to yes, and the base table block requires the Query All Records property set to yes.
WHEN-VALIDATE-ITEM on DATA_PK
:CONTROL.PK_COPY := :DATA_PK;
if :NO_OF_MATCHES > 1 then
message('You have already used that one');
Raise form_trigger_failure;
end if;

How to do it in multi-record block

Hi all,
i have 1 text items in a multi-record block number of record displayed 10
and i have values like 100 , 50, 30 in first 3 records and in 5th record i want to put some value like
20 then i want to calculate all values like 100 + 50 + 30 +20 = 200 and i want to put the total value in a single record block.
but my problem is i cannot able to calculate all the value because for the totale value i have to
write a for loop to loop through the record
but go_block() is not working in post_change .
if any solution is there plz suggest.......

Hi zeeshan
my problem is i cannot able to calculate all the value because for the total value
put the total value in a single record block.
First pls the following...
Guidelines for Working with Calculated Items Calculated items_
1- They are display-only control items.
2-Calculated items cannot be database items.
3.While you can set a calculated item's Enabled, Mouse Navigate, and Keyboard Navigable properties to Yes,
you cannot set the Insert Allowed or Update Allowed properties to Yes
Second Keyword: TOTAL is a reserved oracle key word... pls read the Details...
go_block() is not working in post_change .well u can use timers but no need for it u can reference block item but first u have to accumulate the values per record in WHEN-VALIDATE-ITEM TRIGGER in the last calculated item which is inserted by the user and assign it to the display item in ur current multi-record block :*block_name.total_item*.. as follow...
:block_name.total_item := :item1 + .... ; Then u create a second display item > no of records property = 1 , named e.g. final_summarized_totals
In order to summarize this total values accumulated in the multi-record display item named e.g. block_name.total_item
Finally using PRE-INSERT , PRE-UPDATE,PRE-DELETE Triggers to assign the value calculated into the display item * block_name.total_item* into the db_item into the previously mentioned Trigger Block-Level Off-course.
:block_name.total_db_tem := :i:block_name.final_summarized_totals ; Hope this helps...

How can I create a loop in a multi-record block (on the background)

I have a multi-record block.
In one item I change a value.
Upon this change, in the when-validate-item I would like to
change other records in the same block.
I planned to loop the block with go_record and to do my things
in each record. Unfortunately the go_record built-in is
restricted and cannot be used in a wvi-trigger.
Another approach can be to update the records in the database
and to perform an execute_query after this change. Also this
procedure cannot be used in a wvi.
How can I easily loop in a multi-record block???

You can try to put loop with go_record in KEY-NEXT-ITEM on that
field.
Or if you change something and then press KEY-COMMIT you can
update another records in database and after commit do again
execute_query. Something like :
on KEY-COMMIT:
update_another_records;
commit_form;
execute_query;

How to call a report with a bind variable from a multi-record block

Hi,
I have created a report using the BI Publisher functionality. I did all the integration, created the SQL Query and uploaded the template. Up till here everythings fine!
My SQL Query has 2 bind variables.
I will call my report from a multi record block, at the end of each record an icon is shown which the user can click to open the report.
I created a column link for this item (PRINT_REPORT=Inschrijvingsformulier) but I do not manage to pass the parameters to my report. The parameters I want to pass are 2 columns in this Multi Record block.
I created 2 hidden fields on the page P9_PARAMETER1, P9_PARAMETER2 with the same names as my bind variables and fill this in with the values #PARAMETER1#, #PARAMETER2# from the multi record block.
It seems it does not work as my report stays empty. (also XML file stays empty).
Am I trying the wrong way?
Thanks for any advice,
Kris

hi khadeer,
create one report program and write the required code,and call this function module 'SSF_FUNCTION_MODULE_NAME' and give your smartform name and also when u activate ur smart form u will get one function module call that function module also and specify any tables used...
i think this solves ur problem...
any queries revert back..
pls reward points if helpful,

How to do validation on multi record block at run time...

Dear Friends,
I have to do validation at run time on multi record block.
If user tries to enter and save two or more records in same multi record block with same data at run time, it should not allow it and display a message like, " error : Records are having same(duplicate) values. "
I already did validation with the data coming from database table using cursor. But confused about how to do at run time(on one screen only) ??
Please, give details about how to check duplicate records on form block before saving it to the table ????
Regarding details would be greatly helpful.
thanks,

Hi...Pankaj
thanx for your reply..
I already did validation for the data coming from table....
but I need to do it on form only...at run time...
exa...
In one multi record block
record no : column 1 : column 2 : column 3
1 abc 123 hi
2 abc 123 hi
so it should check on the form itself, here I m not getting data from table...I am just
navigating from first record to second using down arrow.
so, may be 2 possibilities.
1) when user navigates using tab to third record, it should say like two duplicate records.(may be like when validate record or item)
2) or when user tries to save, it should say two duplicate records.
so, everyting should take place on form screen only.....
waiting for your reply,
thanx...

Check box in a multi record block

I have a multi record block that has a check box. I need to be able to go to the first record on the block, go through each row and check to see if it's selected. I will then get all the rows that were selected and passed it as a parameter in a package.I have already declared a global variable in the package to get all the rows selected.
Can anyone please help.

Hi
This is my solution for your problem. If I understand correctly as you have to post the selected records from form to journal entry (a server operation). What you need to do is in your Oracle Forms multi record block construct a loop which goes from first record to last record of your data block, capture the selected records (wherever the check box is CHECKED ON) into a PL/SQL table structure (PL/SQL table is quite simillar to Oracle Forms RECORD GROUP structure, but more versatile as it can be recognized on the back end too).
Once you populate the PL/SQL table with the selected record, pass the PL/SQL table itself as parameter to your package.
Open the PL/SQL table in your destination code and do further processing with those selected records !!
Hope this will work !!

Setting background color in multi record block

Hi all!
I've a table with around 150 records of colors with html-color-names and rgb codes.
I would like to have a sample item in my form 9.0.4 to display the color as a preview for
each record in a multi-record block when querying the table.
I would not like to create a visual attribute for each color. So display_item() is no choice.
(except: somebody show me how to create va's with the japi)
Somebody knows a way to accomplish this?
Thanks in advance and regards
Stauder

Here's a solution which should work :
1. Use a mirror item for the numeric item which has to
be displayed
using the format mask based on value in column1
The data type of the mirror item : Char
X and Y co-ordinates : Same as the item
on which it is
mirrored
Size and Height : Same as the item
on which it is
mirrored
2. On normal display, Mirror item is displayed
3. When Mouse-Click or Pre-Text Item trigger on the
Mirror Item :
- Use the Go_Item ('Actual Numeric Item');
This will bring up the Numeric Item and the Mirror
item goes in hiding
- A VWI trigger on Numeric Item should Then be :
If ( :col1 = 'A' ) Then
:Mirror_Item :=
To_char(:NumericItem, ',999,999.99');
Else
:Mirror_Item :=
To_char(:NumericItem, '99999999');
End If;
4. A key-Next-Item (On Numeric Item) or other trigger ??
should then
use Go_Item (:Mirror Item) to bring forward the
formatted numeric item

Check duplicate data entry in multi record block,which is a mandatory field

Dear all,
I have a situation where i have to check duplicate data entry(on a particular field,which is a mandatory field,i.e. it cannot be skipped by user without entering value) while data key-in in a Multi Record block.
As for reference I have used a logic,such as
1>In a When-Validate-Record trigger of that block I am assigning the value of that current item in Table type variable(collection type)
as this trigger fire every time as soon as i leave that record,so its assigning the value of that current time.And this process continues
then
2>In a When-Validate-Item trigger of that corresponding item(i.e. the trigger is at item level) has been written,where it compares the value of that current item and the value stored in Table type variable(collection type) of When-Validate-Record trigger.If the current item value is matched with any value stored in Table type variable I am showing a message of ('Duplicate Record') following by raise_form_trigger failure
This code is working fine for checking duplicate value of that multi record field
The problem is that,if user enter the value in that field,and then goes to next field,enter value to that field and then press 'Enter Query 'icon,the bolth Validate trigger fires.As result first when-validate record fires,which stores that value,and then when-validate-item fires,as a result it shows duplicate record message
Please give me a meaningful logic or code for solving this problem
Any other logic to solve this problem is also welcome

@Ammad Ahmed
first of all thanks .your logic worked,but still i have some little bit of problem,
now the requirement is a master detail form where both master and detail is multirecord ,where detail cannot have duplicate record,
such as..........
MASTER:--
A code
A1
A2
DETAIL:--
D code
d1
d2 <-valid as for master A1 , detail d1 ,d2 are not duplicate
d2 <--invalid as as for master A1 , detail d2 ,d2 are duplicate
validation rule: A Code –D Code combination is unique. The system will stop users from entering duplicate D Code for a A Code. Appropriate error message will be displayed.*
actually i am facing a typical problem,the same logic i have been applied in detail section ,its working fine when i am inserting new records.problem starts when i query,after query in ' a ' field say 2 records (i.e. which has been earlier saved) has been pasted,now if i insert a new record with the value exactly same with the already present value in the screen(i.e. value populated after query) its not showing duplicate.................could u tell me the reason?and help me out...............its urgent plzzzzzzzzz
