Oracle Forms Version : 6iCreated two blocks
Block-1(Search block)
======================
Block Name: BLK_SEARCH with one item - created as non-database block
Items
object_name - text item
Push Button
Search
Block-2(Update block)
======================
Blockname: OBJECT_UPDATE
Text Items
Object_name
object_type
actual_creation_date
Objective: When i enter object_name and click on "Search" button then the records should be fetched and i should be in position to update any values in the OBJECT_UPDATE block.
i.e
Object_name
object_type
actual_creation_date
Instead throwing error:-
APP-FND-01206: This record already exists. You have entered a duplicate value or sequence of values that must be unique for every record.
I have tried the below option too... Still throwing the same message :(
Option - 1
===========
At the block level, I set the property for Enforce Primary Key "Y", and for corresponding item property, I made Primary Key as "Y". Issue got resolved.
Option - 2
===========
Tried setting block property...still not working
DECLARE
CURSOR c_search(p_obj_name IN ..%TYPE) IS
SELECT object_name,object_type,actual_Creation_Date
FROM object_changes
WHERE object_name LIKE p_obj_name  || '%';
r_search c_search%ROWTYPE;
BEGIN
IF :blk_search.object_name IS not NULL
THEN        
GO_BLOCK('OBJECT_UPDATE');
SET_BLOCK_PROPERTY('OBJECT_UPDATE',INSERT_ALLOWED,PROPERTY_TRUE);
SET_BLOCK_PROPERTY('OBJECT_UPDATE',DELETE_ALLOWED,PROPERTY_TRUE);
SET_BLOCK_PROPERTY('OBJECT_UPDATE',UPDATE_ALLOWED,PROPERTY_TRUE);
FOR r_search IN c_search(:BLK_SEARCH.object_name) LOOP
:OBJECT_UPDATE.OBJECT_NAME:=r_search.OBJECT_NAME;
:OBJECT_UPDATE.OBJECT_TYPE:=r_search.OBJECT_TYPE;
:OBJECT_UPDATE.ACTUAL_CREATION_DATE :=r_search.ACTUAL_CREATION_DATE;
next_record;
END LOOP;
FIRST_RECORD;
END IF;
END;Please help.

Thanks Andreas ; when i search with the single column that really helped. :)
Now in my current search block i have three items.
User should be in position to give any of the following search and they should be in position to update too.
I have given in the WHERE clause as below; but it fetched all the records :( wonder whats the problem.
object_number LIKE :BLK_SEARCH.object_number  || '%' OR object_name LIKE :BLK_SEARCH.object_name  || '%' || '%' OR object_type LIKE :BLK_SEARCH.object_type  || '%'
BLK_SEARCH Frame
============
Object name   ---               Object Type  ----                  Object Number ----
---Search Output Frame-----------------------------------------
Object Name        Object Type        Creation Date        Creation Time            Object Number
TEMP1                 Table                 1/12/12                10:00:00                   1234
TEMP2                 Table                 1/12/11                10:00:00                   899
TEMP1                 Table                 1/12/12                10:00:00                   12
e.g; user gives Object name   as TEMP               Object Type  NULL                Object Number 12
then it should fetch:-
---Search Output Frame-----------------------------------------
Object Name        Object Type        Creation Date        Creation Time            Object Number
TEMP1                 Table                 1/12/12                10:00:00                   1234
TEMP1                 Table                 1/12/12                10:00:00                   12Thanks in advance...
