Run Time Validation Or Validation From Dynamic Action By JavaScript in Oracle Apex
STEP-1: CREATE JS FUNCTION ON PAGE LEVEL JUST PASTE THE BELOW CODE
function myerror(){
var myval = apex.item('P6_ERR').getValue();//document.getElementById('P6_ERR').value;
apex.message.clearErrors();
apex.message.showErrors(
[
{
"type": "error",
"location": "page",
"message": myval
}]
);
}
STEP-2: CALL THE FUNCTION ON ONCHANGE EVENT ON YOUR SPECIFIC ITEM ON CUSTOM ATTRIBUTE
onchange="myerror();"
STEP-3: CREATE A DYNAMIC ACTION ON CLICK OR AS YOU WISH PASTHE BELOW SAMPLE CODE
EVENT: CLICK
ACTION: EXECUTE PL/SQL CODE
BEGIN
IF LENGTH(:P6_NEW)>=10 THEN
:P6_ERR :='Length must not exceed 10 digit....';
--RAISE_APPLICATION_ERROR(-20001,'Length must not exceed 4 digit....');
elsif LENGTH(:P6_NEW)>=5 THEN
:P6_ERR :='Length must not exceed 4 digit....';
end if;
exception
when others then
:P6_ERR :=SQLERRM;
--RAISE_APPLICATION_ERROR(-20001,'Length must not exceed 4 digit');
END;

Work With apex_collection in Oracle Apex
1. Create apex_collection :
apex_collection.create_collection('NAME');
2. Existence Check:
apex_collection.collection_exists ('NAME');
3. Add Member:
apex_collection.add_member (p_collection_name => 'NAME',
p_c001 => :P2_ITEM1,
p_c002 => :P2_ITEM2,
p_c003 => :P2_ITEM3);
4. Collection to Database table data transcfer:
BEGIN
FOR i IN ( SELECT c001 AS a, c002 AS b, c003 AS c
FROM apex_collections
WHERE collection_name = 'NAME'
ORDER BY 1)
LOOP
INSERT INTO DATABASE_TABLE (COLUMN1, COLUMN2, COLUMN3)
VALUES (i.a, i.b, i.c);
END LOOP;
COMMIT;
END;
5. Truncate Collection:
apex_collection.truncate_collection(p_collection_name => 'NAME');
6. Delete Collection Member :
apex_collection.delete_member(
p_collection_name => collection name,
p_seq => member sequence number);
7. Delete All Collecion Members:
apex_collection.delete_members(
p_collection_name => collection name,
p_attr_number => number of attribute used to match for the specified
attribute value for deletion,
p_attr_value => attribute value of the member attribute used to match for deletion);
8. Delete Collection :
apex_collection.delete_collection (
p_collection_name =>'NAME');
1. Create apex_collection : (Collection Name Must be in Capital letter) apex_collection.create_collection('NAME');
BEGIN FOR i IN ( SELECT c001 AS a, c002 AS b, c003 AS c FROM apex_collections WHERE collection_name = 'NAME' ORDER BY 1) LOOP INSERT INTO DATABASE_TABLE (COLUMN1, COLUMN2, COLUMN3) VALUES (i.a, i.b, i.c); END LOOP; COMMIT; END;
apex_collection.delete_member( p_collection_name => collection name, p_seq => member sequence number);
7. Delete All Collecion Members:
apex_collection.delete_members( p_collection_name => collection name, p_attr_number => number of attribute used to match for the specified attribute value for deletion, p_attr_value => attribute value of the member attribute used to match for deletion);
8. Delete Collection :

1.Create report and take a column as link.
2.Create another region for modal and put a static ld like ‘m’
3.Then Link -> Target -> URL type and wright the code like this one.
Here P1_ID is the item where you want to assign the value and #ID# is report value.
And ‘m’ is the static id of modal region and this region template should be Inline Dialog .
javascript:$s('P1_ID','#ID#','#ID#'); javascript:openModal('m');
