How can I hide primary key column in BC4J form

I have populated a primary key with dbsequence and how can I hide it on the form. It is populated in the DB by a trigger.

I have populated a primary key with dbsequence and how can I hide it on the form. It is populated in the DB by a trigger. To hide it, edit the attribute using attribute-editor that you bring up by double-clicking on the attribute in the "StructurePane" .
Then go to control-hints panel and mark the attribute setting for Display = Hide.
Then UI wizards will not add the attribute into generated panels.
However once you have UI generated, this hint is no more used.

Can a composite primary key column be null

Hi All,
It will be a silly question but still I would like to ask can a composite primary key column be null?
Thanks,
Rafi.

Rafi,
Why you think it would be allowed?

How to change (decrease) primary key column length?

Hi all,
I have plenty of data in the table and I need to decrease the primary key column from CHAR(17) to CHAR(13).
I try to use:
ALTER TABLE xx MODIFY (prmy_key (13));
but Oracle give:
ERROR at line 1:
ORA-01441: column to be modified must be empty to decrease column length
Can anyone give me advice on what is the best way to decrease column length? Thanks in advance for your help.

To add to the above, I have done a simple test in the lines that I was suggesting the solution for this problem,
   CREATE TABLE testA
   (pk_col   varchar2(20), jd date, constraint pk1 PRIMARY KEY(pk_col));
   --Insert data into testA
   create table testB as select * from testA;
   TRUNCATE table testA;
   ALTER TABLE testA modify(pk_col VARCHAR2(10));
   INSERT INTO testA SELECT substr(pk_col, 1, 10), jd from testB;
   DROP TABLE testB;
   Select constraint_name, constraint_type, status from all_constraints
   Where table_name = 'TESTA';
   CONSTRAINT_NAME                C STATUS
   PK1                            P ENABLEDAlter command is successful as the table is empty. TRUNCATE flushes the data and resets the high water mark keeping all the constraints. If we safely want to use the TRUNCATE as far as storage issues are concerned,
TRUNCATE table table_name reuse storage;
I think, this would accoplish what has been asked.

Missing primary key column in created form?

Please help. I am a newbie in apex.
When i create form and view it later I am missing primary key column.
HOw to make it show?
Thanks in advance.

Hi,
While creating the form based on a table/view, what have you chosen to populate the primary key value? Existing Triggers or Existing Sequences or Custom PL/SQL function?
Can you check for the Get PK pl/sql process in the page processing region of the related form page? If that function is missing then do the following steps to create the same,
Step 1 : Create a new pl/sql process.
Step 2 : Choose the Process Point as, On Submit After Computations and Validations.
Step 3 : Write the following block,
declare
function get_pk return varchar2
is
begin
    for c1 in (select TEST_SEQ.nextval next_val
               from dual) -- Create a new sequence for your requirement.
    loop
        return c1.next_val;
    end loop;
end;
begin
:P3_TEST := get_pk; -- Change the item name for your page.
end;After doing all the above, try executing the page.

Sakthi.

One of the guidelines when selecting column for a primary key is:
Choose a column whose data values are never changed. A primary key value is only used to identify a row in the table, and its data should never be used for any other purpose. Therefore, primary key values should rarely or never be changed.
Cheers!

Hi,
well at least you can use some vba macros to achieve that. Best would be to have a static query embedded in a workbook and a sheet where the results are displayed as copies from the query via a macro.

hi,
it might be that there is an initialization error in your code...
try something like this (you can use visible or enable property).
tell me your email and i will send you sample form and menu with the following code ...
declare
menu_item_name     varchar2(40) := 'MENU2.ITEM23';
menu_item_id     MenuItem;
begin
menu_item_id := find_menu_item(menu_item_name);
/*if (not id_null(menu_item_id)) then
if (GET_MENU_ITEM_PROPERTY(MENU_ITEM_NAME, visible)='TRUE') then
     set_menu_item_property(menu_item_id, visible, property_false);
else
     set_menu_item_property(menu_item_id, visible, property_true);
end if;
else
message(' cannot find menu item!');
     raise form_trigger_failure;
end if;
if (not id_null(menu_item_id)) then
if (GET_MENU_ITEM_PROPERTY(MENU_ITEM_NAME, enabled)='TRUE') then
     set_menu_item_property(menu_item_id, enabled, property_false);
else
     set_menu_item_property(menu_item_id, enabled, property_true);
end if;

How can I modify a column to a primary key column

Hi,
I've created a table with no primary key. How I can set the primary key column now? The datatype of the "primary key" column is Raw(35).
Thanks,
Mike

Mike,
Issue the following command:
ALTER TABLE table_name
ADD CONSTRAINT constraint_name PRIMARY KEY(column_name);
NOTE: If you want to place the primary key data in a separate tablespace, then you can add the key word USING INDEX TABLESPACE after the column_name.

John

How to know primary key column name form a table name in sql query

Suppose I only know the table name. How to get its primary key column name from the table name?
Thanks

Views don't have primary keys though their underlying tables might. You'd need to pick apart the view to determine where it's columns are coming from.
You can select the text of the view in question from user_views.

How to modify primary key column?

I want to modify one primary key column, But TT reported error.
How do I modify primary key column? Thanks first.

In TimesTen, the values in primary key columns cannot be updated (except for the trivial case where you update the value to the same value as it currently has). If you want to change the values stored in primary key columns the application must insert a new row with the new key values (and of course values for the other columns) and then delete the old row.
