Primary Key in tabular form is not a number

I created a table called tblRegions.
The primary key is RegionCode(VarChar2) - example - USA.
I then tried to create an updateable Tabular Form using tblRegions, but it won't let me choose the primary key as an updateable field.

O.K.
1. create a trigger which will populate a real primary key out of a sequence - search internet
on triggers and sequences in oracle
2. use this primary key for tabular form processing
3. if you need a manually entered pseudo (fake) primary key, you can handle this column
as any other - tabular form will not complain about it
4. you may create a constraint on your table, which will take care this column is allways
populated and unique - this is not the nicest way since it involves processing and the errors
you gat may not look user friendly. However, this is the most secure and easiest way -
you don't need to write any code on the application side to handle eventual errors.
Search internet on constraints.
5. you may decide to create a manual validation process to fetch the eventual errors
before you commit the changes to the database. This forum is full of the threads on
the topic "tabular form" and "manual creation of tabular forms". If you are new to apex,
you should stay away from that for the first (this is only my opinion).

Tabular form does not update

I don't have a problem, but I would like to offer a solution to people who might make the same mistake as I did:
When you build a tabular form on a table and the submit button does not seem to work, check whether your table has a primary key.
I created a table, triggers and all the other constraints and for some reason the (tabular) form I created did not update the table, even though I had told it that the primary key was the ID in the table and it was filled by a trigger (which was true).
I tried creating a different form on a different table and then I noticed that the primary key was filled in for me this time, and that this hadn't been the case in the first form. I added the primary key to the table and voila, problem solved.
Is this intended behavior ? I wonder why the user is allowed to specify the primary key when the wizard does not find it, because this does not seem to have any effect. So why not try to find the primary key and warn the user when it is not present?
Just my 2 cents....

Sloger,
if this is your tabular form
SELECT apex_item.checkbox (30,
...and this is your update statement
FOR i IN 1..APEX_APPLICATION.G_f*30*.COUNT
...Then you will only ever update records that have been checked. Unchecked checkboxes are not passed back in the global array. You need to have a hidden column with the ID's for the record and loop through that when you are updating/inserting. That is why the built in tabular form has a MRU and a MRD. the MRU loops through the hidden ID column. The MRD loops through the checkbox.

How can I be able to create a primary key in a Form on a Table with Report?

When I click the "Create" button, a form appears allowing me type in data for those columns. But primary key is not there. I really need to specify my primary key here also. Because the primary key for this table is a Serial Number, not just a sequence number.
I noticed that when I created this page earlier, the primary key was ruled out by default. I wish there is a way to accomplish this. Thanks!

Hello,
>> a pk field is not null implicit …
I’m not sure I understand your statement. Every item, including the one holds the primary key, is null for a new form. The question is, when you are filling the form, how to populate this field. The APEX wizard assumes this field will be populated by the system, hence it hides it from the user, however it’s a valid situation where the primary field is filled by the user.
As primary field should not be changed, hence the productive advice by Martin. If the form displays an existing record, the primary field item should be set to Read Only.

Arie.

Primary key in new form wizard

I tried to create a form with report using the New Form Wizards. But it seems always hidden the primary key and if I make changes to the generated form or report, I normally end up with broken pages. I found the forms in the example application are against tables with sequence backed primary key. But all our tables are not use that approach. Does anyone know any work around?
Another unrelated question about LOV? It seems the wizard require two different column to be used. If I want a list based on one column (like show all the possible value of one column), how can I do that?

i just created a "Form with Report" and a "Form on a Table or View" using the wizards on htmldb.oracle.com which i accessed a few different ways, and they seemed to consistently expose the primary key of my table in the form. if you're referring to your primary key column in your report being rendered as an edit icon, you can change that from the report column attributes screen for your primary key column. just use the popup LOV for the "Link Text" field in the "Column Link" region of that screen to select the primary key value from your query rather than the html image tag that's there by default. also, if you'd like to, let us know what tweaks you're making to your generated forms/reports that result in errors. we should be able to help you with those, too.
i think the last part of your question above asks about using the wizards against tables that don't have sequence-backed primary keys. if so, i just did that on htmldb.oracle.com w/o issues. i might not be understanding your issue correctly, but it seems like you shouldn't have problems doing this. if so, though, please provide much more detail. we did have some issues with this stuff (and with the primary key column not being exposed as you mentioned above) in some earlier versions of html db. is it possible that you're not running of the most current version: 1.4.2.00.21 ?

<raj>
html db likes you to define your LOV queries using both a value to be displayed and a value to be returned to be submitted. if you'd like these values to be the same, simply select the same value twice from your table (being sure to alias the columns, which is always a good habit). so if you want to show and return all values of ename from emp, you could define your LOV query to be something like...
select ename my_display_val, ename my_return_val from emp order by 1
...and that'd do it.

Getting the primary key from order form

Does anyone know how to get the primary key (DocEntry) off of the order form for an existing order? I don't really want to use the DocNum field since it is not the primary key and theoretically two different orders could have the same DocNum. Thanks in advance for your help.

Hi Joe,
DocEntry and DocNum values are unique, so you cannot have in db 2 orders with the same DocNum. It's possible, that DocEntry and DocNum values can vary.
If you know the DocNum value (f.e. from Order's Form), you can simple use RecordSet object:
Dim sQuery as String
Dim oOrder as SAPbobsCOM.Documents
Dim oRecordSet As SAPbobsCOM.Recordset
Set oOrder = oCompany.GetBusinessObject(oOrders)
Set oRecordSet = oCompany.GetBusinessObject(BoRecordset)
sQuery = "Select DocEntry From ORDR Where DocNum = '" & DocNumber & "'"
oRecordSet.doQuery sQuery
If oRecordSet.RecordCount > 0 Then
oOrder.GetByKey(oRecordSet.Fields(0).Value)
End If
And this should work.

Libor.

Tabular Form Validation not working in tabular form APEX 4.0

Hi,
I am using APEX 4.0. I have a tabular form with Tabular form validation done with it.
Item not null is the validation.. so if I dont type any value in the any of the fields in the tabular form and press the Submit button, the first time error is shown... but when I click the Submit button again, with still the empty rows the page is submitted.
How to resolve this issue?

Insert in Tabular form does not work after the upgrade to APEX 4.0

Hi all,
Thx in advance for looking into the issue.
We are running into following issue when we upgraded APEX 3.2 to APEX 4.02
1) The Tabular form insert does not work.
2) We are fatching the value of the Global variable APEX_APPLICATION.g_XXXX in a procedure and we get null for this value after submit for new row to be inserted.
The tabular form was working fine in APEX 3.2.
The Update and Delete works just fine.
Any help in this regard is highly appreciated.
Thx and regards,
Mahesh

Here is my workaround to get the ADDROW/SUBMIT working again if you have a legacy Tabular Form:
1     PAGE ATTRIBUTES
          JAVASCRIPT
          FUNCTION AND GLOBAL VARIABLE DECLARATION
               var htmldb_delete_message='"DELETE_CONFIRM_MSG"';
2     DELETE BUTTON
          ACTION WHEN BUTTON CLICKED
          URL Target          change to
               javascript:apex.confirm(htmldb_delete_message,'MULTI_ROW_DELETE');
3     ADDROW BUTTON
          ACTION WHEN BUTTON CLICKED
          Action
               redirect to URL
          URL Target
               javascript:addRow();
4     PROCESS
          APPLYMRU (activitated by button ADDROW)
          CONDITION
               never or delete
5     PROCESS
          ADDROWS
          CONDITION
               never or delete
6     CHANGE PAGE TEMPLATE to e.g. THEME 13 One Level Tabs.
7     IF YOU WANT ADD FUNCTIONALITY TO GOTO BOTTOM OF PAGE AFTER ADDROW
     1. In the page footer put <a name="bottom_of_page"></a>
     2. Amend the action when the "ADD" button is clicked to scroll down to the new region by doing the following:
     - edit "ADD" button
     - Go to "Action when button Clicked" section
     - Amend "URL Target" from
     javascript:addRow();
     to
     javascript:addRow();window.location='#bottom_of_page' ;

How to change the source type for a primary key on a form?

Hi,
At the time of creating a form, I had set the source type for the primary key to an existing sequence.
Now I want to change the source to a trigger.
Can anyone suggest how to do it?
Thanks in advance,

Setting primary key field value in jdoPrestore() not flushed to database ?BUG?

Hello,
When I set value of primary key field of a new instance in jdoPrestore() new
value does not get flushed to database - old (default) value get stored
instead. All other fields assigned in jdoPrestore() get successfully
flushed except primary key one.
Alex

Abe,
You fixed only part of the problem. Right now if I assign value to a PK
field in jdoPreStore() it does get flushed but there is another issue - all
other instances which referenced the one I assigned PK to will not get this
PK value. Example A references B, in B.jdoPreStore() I generate id for B -
b.id = 100. When A gets flushed it would not get 100 in its b_id field.
Specs says:
This method is called ***before the values are stored from the instance to
the StateManager***.
Data store fields that might have been affected by modified non-persistent
fields should
be updated in this method. This method is modified by the enhancer so that
changes to
persistent fields will be reflected in the data store.
The context in which this call is made allows access to the
PersistenceManager and
other persistent JDO instances.
I read it as callbacks should be invoked on ALL instances before they get
stored to StateManager. Does Kodo invoke callbacks for all istances first
and then store them to instance manager? Based on the problem I am having it
does not look like it

Setting default value to columns on tabular form is not working.

Hi,
I created a tabular form and i want to set some default values to columns based on the values in page items.
so i set the page item to column value in tabular form attributes by selecting the Default type as PLSQL Expression & Function DEFAULT value &P24_ISSUE_ID. it worked fine but
in the similar way i tried for the another column by selecting the default type as pl/sql expression & function and default value &P24_CASE_NAME.
but it throwing an error for this like failed to parse SQL query: ORA-00904: "C254DB": invalid identifier
i don't understand where i gone wrong even i checked for the data types of the columns, everything is fine.
so please help me out of this problem.

*&P24_ISSUE_ID.* is not a "PL/SQL Expression or Function".
but it throwing an error for this like failed to parse SQL query: ORA-00904: "C254DB": invalid identifierWhat you are doing results in the APEX engine substituting the P24_CASE_NAME value "C254DB" into the default value and then trying to evaluate this string as a piece of PL/SQL. Outside of a block in which it is defined as a variable, constant or function "C254DB" is not a valid PL/SQL expression.

Sorting on date (date_popup2) in manual tabular form does not work

Hi All,
I created a manual tabular form (based on a collection) with 1 date_popup2 field in it. This field is defined in the query as follows:
,      apex_item.date_popup2( p_idx                   => 18
                            , p_value                 => c004
                            , p_date_format           => 'dd-mm-yyyy'
                            , p_item_id               => 'f18_' || lpad (rownum, 4, '0')
                            , p_item_label            => 'Start date'
                            ) as tf_br_start_date
In the report attributes I marked this column to be sortable.
However, in the page the sorting is not working. It looks like it's always sorted in the order of the seq_id.
Can anyone tell me how to solve this?
Regards,
René

I'd call it a bug/missing feature.
It appears that within a Basic report, sorting on a column created using APEX_ITEM.DATE_POPUP2() does not sort by date.
I'd file this with Oracle Support and see what they say.
Include a link to this thread and your workspace login information.
I got something to work by: (probably not what you want.)
using the C004 column directly. (I just added it to the SQL code)
setting the column's attribute "Display As" to "Date Picker"
setting the column's attribute "Number /Date Format" to DD-MM-YYYY
I suspect: since you don't start with p_idx => 1, this column becomes "1" ==> g_f01

Manual Tabular Form - Items not rendered

Hi,
i'm trying to build a manual tabular form:
I added a blnak page with a Report Region using a SQL Query in a Classic Report:
select apex_item.text(1,"EMPNO") as "EMPNO",
apex_item.text(2,"ENAME") as "ENAME",
apex_item.text(3,"JOB") as "JOB",
apex_item.text(4,"MGR") as "MGR",
apex_item.text(5,"HIREDATE") as "HIREDATE"
from "EMP" "EMP"The items are not rendered in the report, but the HTML Text is displayed instead.
See http://tinypic.com/r/2e6bqdu/5
I played around with "Display As" in the Column Attributes - no luck.
I used this links as reference:

The "Display As" for each column should be "Standard Report Column".
Seems the default "Display as" for standard reports has changed:
I created your standard report in a 3.2 environment and the report defaulted the "Display As" for each column to "Standard Report Column".
I created your standard report in my own 4.0 environment and in the hosted apex.oracle.com environment and the report defaulted the "Display As" for each column to "Display as Text (escape special characters, does not save state)"

Primary Key on Char + Form Report Edit

Hello all,
i'm new here :)
I have a question regarding Apex 3.0
I created a table with a primary key on char(5).
After that I created a form with report.
If i click now on the edit button in the report on a row, I receive this error on edit page:
ORA-01403: no data found
Unable to fetch row.
If the "id" is a int, it works without problems
Could someone help me?

Hi,
When you go to page 3 in edit mode, you give a value to P3_QNR (the PK).
If this value doesnt exist in your table, you'll get the following error : ORA-01403: no data found - Error Unable to fetch row.
From what I understand of your problem, if you change de datatype of your primary key, you can fix/create the same error.
after some testing : I was able to have the same error... and fix it
The problem : if your primary keys starts or end with blank spaces, APEX can't handle it (in the url, APEX don't add %20 to replace the blank spaces)
The fix : make sure your primary keys don't start or end with blank spaces
I hope this help

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.

Updating a table through a manually created tabular form does not work.

Hi Friends,
I don't know why the "On submit - After computations and validations" process does not update the referenced table. May I miss something. Here is my source :

apex_item.hidden(2,tcs_tcs_id) tcs,
apex_item.text(3,eqp_equip_name,50) name,
apex_item.text(4,eqp_equip_ident,50) ident,
apex_item.text(5,eqp_equip_type,15) type
from equip_physical
where tcs_tcs_id = :P1_TCS_ID
and here is the process source
FORALL i IN 1..apex_application.g_f01.count
UPDATE equip_physical
SET eqp_equip_name=apex_application.g_f03(i),
eqp_equip_ident=apex_application.g_f04(i),
eqp_equip_type=apex_application.g_f05(i)
WHERE eqp_id=apex_application.g_f01(i);
No error message is displayed and my success message associated to the process is displayed. But the modified text field value is erased and the database table is not updated.
