Check Duplicate data during data key-in Multi Record Block

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 here is that suppose if usee gets a message of ('Duplicate Record') and after that without saving the values if user try to query of that block then also when validate item fired where as I am expecting ORACLE default alert message('Do You want to save?'),I want to restrict this When-Validate Item fire during query time..........................while user try to query.
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

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 !!

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 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...

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

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;

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

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.

Deleting selected record in a multi-record block

I am using Form 6i.
I have two multi-record block viz. BLK_A and BLK_B.
BLK_A has record displayed property set to 4
BLK_B has record displayed property set to 8
Each block has checkbox item.
BLK_A contains records retrieved from table after entering data in selection criteria.
When checked on anyone checkbox of BLK_A, then it displays related information in BLK_B.
But when I uncheck the checkbox of BLK_A, then how to delete records in BLK_B.
Thanks in advance.
Regards,
Vikas

No, absolutely not.
I cannot use this method.
Because if two checkbox is check in BLK_A, then records related to both record in BLK_A will display in BLK_B. If I uncheck any one checkbox of BLK_A, then only records related to that checkbox should be deleted.
If I use your suggestion, then all data will be removed.
Thanks and regards,
Vikas

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.

Problem in displaying records in multi record block

Hi all,
I have a problem in displaying records in a multi record block in a form.
I have 1 control block and 1 data block(multi-record block).
Control block has one item CUSTOMER-ID. Data block has many other items related to customer.
when a value is entered in customer-id text item, all the relavant details should be displayed in the data block.
but, the records are overlapping in the same line in the data block, actually they have to be displayed one record per one line.
The code is,
IF :CUST_BLOCK.CUST_ID IS NOT NULL THEN
GO_BLOCK('XBSI_CONTRACT_PRICE_FACTORS');
FOR C1 IN C
LOOP
:XBSI_CONTRACT_PRICE_FACTORS.CUST_ID:=c1.site_use_id;

Please help me out..
Thanks in advance!

Hi Suman
IF :CUST_BLOCK.CUST_ID IS NOT NULL THEN

Try this. you are trying to show all the records in same line. so its overlapping.

Multi Record Block Problem

Hi,
I have a multi record block with two fields NAME and DATE. On clicking the Save Button a procedure (PROC_BEFORE_SAVE) is called which loops through this block, and deletes empty records.
PROC_BEFORE_SAVE
LOOP
     IF :TI_NAME IS NULL THEN
          DELETE_RECORD;
     END IF;
     NEXT_RECORD;
     EXIT WHEN :SYSTEM.LAST_RECORD = 'TRUE';
END LOOP;
The proc fails and throws error (Oracle Error Unable to Update Records) only for the case that the first few records are null. Sample data given below.
Name  -  Date
NULL  -  NULL
NULL  -  NULL
NULL  -  NULL
AJ  -  10/02/2005
JA  -  12/12/2004
AJV  -  12/12/2002
This happens because it tries to update the NOT NULL field NAME as NULL.
Could somebody please tell me why this is happening? Is there something wrong with the procedure?
I am using Oracle Forms 6.0.8.8.0 in Windows 2000 Professional edition.
Any help would be greatly appreciated.

Hi,

Query about multi record block

Abdetu
Please clarify this
I have a multi record group on the canvas, which displays 5 records at a time. The block is based on a table. All the items, except 3 items are displayed items.Now in the block I have a list item, in which I have two values "PO" and "TSF".. If user selects PO, associated text items will get enabled and user will be entering the values .. Same is the case with TSF .. And at the end user selects Ok button to save the record to the database
Now while fetching the records (based on query) ..once the records are fetched, control will be on PO/TSF list box, now the user can either change PO to TSF or TSF to PO ..or he/she may opt not to change also.. If user changes PO to TSF, only that particular record's TSF fields should get enabled .. The problem what I am facing is, when the control comes to PO/TSF list box.. since its multi record block, all the record's PO/TSF list box are getting enabled
In the sense, if control is in the 1st record of multi record block, only those fields should get enabled, once the user navigates to the text item which is the last of that particular record, then 2nd record should get enabled....
Can I know the solution

Hello Seshu
ur case explanation should be in points 1,2,etc as possible leaving extra lines and spaces in between .. and the case should be more clear and summarized like:
1- I have multi-records data block.
2- I have a static list item with 2 values eg. (a and b).
3- Depending on selecting from the list some items r enabled.etc.
Kindly note that, this will facilitate ur problem to be more readable,recognizable and save time and effort of someone who wants to help u.
Here comes the confusion:
Now while fetching the records (based on query)
The problem what I am facing is, when the control comes to PO/TSF list box.. >since its multi record block, all the record's PO/TSF list box are getting enabled i think with the piece of code i have just posted to u this can't be happened since it disable all the record's PO/TSF.
if this didn't solve ur problem i suggest either u post ur code to help u or u try to put some validations with :
if statment inside the loop depending on the list item's values which will enable or disable related items to the list.
Hope this help u,
If any Questions pls let me know..

Enabling and disabling the button in the multi record block

hi all,
i am using
Forms [32 Bit] Version 6.0.8.24.1 (Production)
Oracle Database 10g Release 10.2.0.1.0 - Production
i have a multi record block each block contains a button(button is to approve the record in terms of changing the status)
i have the items like date,remarks and button
the button should be enabled if the remarks is not null otherwise it should be disabled.
for this in pre-record trigger i have written
if :record is null then
   set_item_property('button',enabled,property_false);
else
      set_item_property('button',enabled,property_false);
end if;what problem is enable and disable is impacting on all the buttons in the block. in other words if first record's remarks is null then all the records button is disabled. if first record's remarks column is not null then all the records of the button column is enabled.
i have to make enable and disable the button for the corresponding record.that means if first record's remarks column is not null then only first records button should be enabled others should be disabled.
Thanks..

You need to set the No. of items displayed to 1 as Ammad had said, additionally you can set the X and Y Position (Just Y will do and having fixed X) of the button depending upon the current record.
can u explain this part alone bit more (setting the position of x and y)You need to calculate the variable Y_POS depending upon the current position of the cursor that is the current record.
You can find the current record Y_POS using combination of
V_CURRENT_RECORD := :SYSTEM.CURSOR_RECORD;
V_TOP_RECORD := GET_BLOCK_PROPERTY ('BLOCK_NAME', TOP_RECORD);
V_ITEM_Y_POS := GET_ITEM_PROPERTY ('ITEM_NAME', Y_POS);
-- Also needs to add the Y_POS of the relative other items in the muti-record block
V_HEIGHT := GET_ITEM_PROPERTY ('BUTTON_NAME', HEIGHT);
-- Note :- TOP_RECORD Returns the record number of the topmost visible record in the given block.
V_Y_POS := V_ITEM_Y_POS + ((V_CURRENT_RECORD - V_TOP_RECORD) * V_HEIGHT);
-- You will need to add Distance between Items in records if anyThen you can Set the current Y_POS of the button.
SET_ITEM_PROPERTY ('BUTTON_NAME', Y_POS, V_Y_POS);
[/code[
Hope this helps
