Automated Row Fetch binding

Hi Experts,
Apex 4.1
This is what i'm trying to do.
I have number of fields in a form.
Value for the Fields are fetched from two different tables using Automated Row Fetch.
When the page loads only one ARF process would run based on a flag value in the application item and only those fields specific to that ARF should be populated.
what i have noticed is when one ARF executed apex tries to bind all the fields on the form which have source type as Db column.
in my case when it tries to bind a field which is basically populated by second ARF. it throws error message.
What i what t know is,
When we have multiple ARF on a page, is there any way to specifiy.. these fields are only populated by this ARF ?
Really appreciate if someone can assisit me on this.
Thanks

You should create custom row-fetch process to achieve this.

Set memory cache - automated row fetch

I would like to know more about the difference between
Set Memory Cache On Display and
Set Memory Cache On Fetch
option, given in the Automated Row Fetch process.
I noticed that it makes a difference in some cases - especially where I have a master-detail relation and need to perform multiple drill down:
e.g. the report shows what was expected but export to .csv returns no rows. After switching from the default 'Set Memory Cache On Fetch' to 'Set Memory Cache On Display' everything works fine.
Where could I find something about this option?
Denes Kubicek

Denes - I'd need to see an example to explain it. It is not the behavior I would expect. Can you create a simple test case on htmldb.oracle.com? Please post the workspace name and app/page ID when you have it.
A bit more info: when the DML Fetch Mode is set to 'Set Memory Cache On Display', references to items sourced by the fetch, say &P1_ENAME., will not return the value that would be displayed in the form item P1_ENAME until after the code that emits P1_ENAME executes. So if your page had a before-header DML Fetch process that fetched a value for P1_ENAME (from EMP) and region A that displayed conditionally based on P1_ENAME = 'SMITH' and then region B containing the form item P1_ENAME and then region C that displayed conditionally based on P1_ENAME = 'JONES', the condition on region A would not see the fetched value of P1_ENAME but the condition on region C would see the value. However, if you set 'DML Fetch Mode to 'Set Memory Cache On Fetch', the condition in region A would see the fetched value.
When you have a csv link or chart region that references a value from session state, that value must have been committed to session state (which happens when you run a computation, do an explicit assignment or "select into" a bind variable associated with a page or application item, or when you submit a form) in order for the csv or chart page to access the current value.

How to trigger the automated row fetch process and open modal window by javascript api?

Hi,
I would like to click the one row of column of IR report, to open the modal window of current page. <----------------it is ok. I can use "javascript:openModal('windowID')" to do it.
There is one form in this modal window, Meanwhile, I would like to pass column data to this form.    <--------------------- it is ok also. I can use " $s('P7_ID','column_value');" to do it.
But I don't know how to trigger the "automated row fetch" process of this form to retrieve other field's value in this form.
I tried to use following 2 ways. But failed.
First method:
add one ajax process of "automated row fetch" in "page processing" block, named "get_fetch_data"
when click IR column , call "openModal", and call "apex.server.process ( "get_fetch_data", {}, { success: function( pData ) { } } );" , I tried to call above ajax process to refresh form. It is failed.
Second method:
add one process of "automated row fetch" in "page rendering" block, named "get_fetch_data"
when click IR column, call javascript api "apex.submit" to submit current page , then call "openModal".
such as : javascript:apex.submit({request:'MODIFY',set:{'P7_ID': #ID#}}); openModal('trade');
But it is failed also. the modal page is showed firstly. then page refresh. but modal window will not open again.
I am not sure if my thinking is right. Could you please provide any suggestion?
Thanks in advance,
Ping

Hi Ping,
You can try to set the session state of your modal page's primary key before opening the modal page. Use one dynamic action (on click of IR row) with two true actions. First one to set session state of modal page pk, second on to open modal page.
Or you can add the modal page url as link in your report by extending your query:
select ...
,         apex_util.prepare_url( 'f?p='||:APP_ID||':7:'||:APP_SESSION||'::'||:DEBUG||':7:P7_ID'||COLUMN_VALUE ) as link
from ...
This will give you the url of the modal page, with set primary key.

Automated Row Fetch for complex primary keys

I would like to post a workaround for using automated row fetch on tables with a complex primary key (more than 2 components).
APEX has the restriction of just beeing able to handle <= 2 PK components, which is not acceptable to me in quite a lot of scenarios.
Imagine a situation where you want to manage recipes for dishes. Each recipe has several versions and each version has several recipe-positions. The PK consists of recipe_id, recipe_version and recipe_position.
You hava a report displaying the positions of a specific recipe version and this report contains an edit link that jumps to a form, where the attributes of a recipe position can be edited.
Creating the edit position form, you can only specify a primary and a secondary key item/column. Given that, if you want to use the edit form by clicking the edit link, you will receive the error "ORA-01422: exact fetch returns more than requested number of rows", because the third PK compound is not used as a restriction.
The workaround is to present the ROWID pseudo-column to the form as the primary key.
Create a (hidden) Item to store the ROWID-Value of the current row and simply change the properties of the ARF-Process to accept ROWID as the PK column and specify the corresponding item.
If automated processing of recipe_position is desired, you can specify it as the secondary key column.
I don't know if this woraround/solution is very ugly, but it works ...
Ingo

Hello Ingo,
I tend to avoid ROWID. In the Interactive Report it's used too.
The ROWID can change, where a Primary Key normally doesn't change, that's the biggest thing I worry about. How does Oracle know not somebody else already updated the row?
I always wonder what happens when you're in a cluster/RAC and use ROWID. Isn't it possible that you get two rows for the same rowid?
Just my thoughts.
Regards,
Dimitri

Table and Primary Key Case Sensitive in Automated Row Fetch

Why are the table and primary key fields case sensitive in the Automated Row Fetch process? I'm debugging an error in this process and I'm not sure what the case should be.

Russ - It's a defect of sorts. Use upper case in the process definition. I don't think these processes will work with tables or columns whose names are not known to the database as upper-case values, i.e., defined using double-quoted non-upper case.

Automated row fetch / Complex primary key

I have a complex primary key made up of ticket_num, ticket_seq because there may be between 1-3 rows associated with one ticket_num.
The problem I am having is the automated row fetch errors out when trying to update a ticket with the following error even though the combination of ticket_num, and ticket_seq are unique, and ticket_num, ticket_seq are entered in the automated row fetch as primary key column, and secondary key column.
ORA-01422: exact fetch returns more than requested number of rows
Is there a way to put both columns as the primary key?

Thanks, Scott. I had the exact same problem, and your suggestion fixed it.
May I suggest that this is a bug in Apex? In the create application wizard, select "Add Page" -> "Report and Form", and select a table with a compound primary key consisting of two columns. Apex will create the report and the form, and will configure the ARF correctly in the form, but it does not specify a value for the second key in the Link Column section of the report attributes.
Thanks,
Mike

Two 'Automated Row Fetch'-processes at one page

All,
I have a page with several fields (P24_xxx_Reg1 & P24_xxx_Reg2) in two regions.
For every region I have an ‘Automated Row Fetch’-process, because they base on different tables.
The second process sets the field values of region 1 to null,
even all is different: fieldnames, sources, regions, processes, etc.
Any help appreciated,
thanks in advance

Create a view on a table you want to update if you have more than two key values.
However, the automated row fetch does support two key values.

Automated Row Fetch

I am struggling to get two forms on the same page work as they are suppose to. One of the problems is with Automated Row Fetch. To condense the problem I tried the following (on a test page):
Created a form/table on table A with primary key PK_A
Among other things this creates the automated row fetch for this form and a field P1_PK_A. containing the PK.
Created another form/table on table B with primary key PK_B which creates automated row fetch for B and P1_PK_B
Since I am concentrating on fetch process deleted all buttons and processes except FETCH row for both forms.
Now:
When I pass a value to P1_PK_A in the URL and no value for P1_PK_B it fetches the row in form A fine, same is true the other way around. However if I pass valid keys for both forms in the URL it fails to fetch row for the second form.
Am I missing something or if not how am I to have two forms on a page?

Thanks for the quick response Joe,
I deleted the process created by the wizard and created another data manipulation process with the wizard - which created another autmated row fetch and makes no difference. By creating the fetch and DML manually do you mean that I have to create PL/SQL process to fetch the values for the second form?
Btw how in the world I missed the part that you can't have two automated DML processes on a page I don't know.

Automated row fetch returns more than one row

Greetings All,
Does anyone know of a way to call a page if the automated row fetch returns more than one row. I have a form with a primary and secondary key. If I search only on the primary key and there is more than one row I would like to call a popup with the multiple list, is this possible?
Regards
Mark

Automated Row Fetch Issue

Hello
I have a form based on a table where i have 2 keys as primary key (col1,col2)==>composite pk.
sample values are like:
col1 col2
1 21
2 21
62 21
62 1
But issue is at the point where the automatic row fetching is getting executed
[Automated Row Processing section on edit page]
Primary column value is col1(only one column is allowed in apex Auto row fetch)
Secondary key column is col2.
For ex, when i access the row for col1=62, it fetches 2 rows where value=62 (based on col1)
and i get error;
(exact fetch returns more than 1 row)
How to avoid this
thanks
kp

Setting the proper page item in the Item Containing Secondary Key Column Value field and proper table column name in the Secondary Key Column of the row fetch screen should work. My off-the-cuff guess would be that either one of those fields does not have the correct value, or when you are branching to this page that the page item containing the secondary key is not being populated.

Automated row fetches, checkboxes and null values

Hi
In Apex3 I have a page with automated fetch row process that is working fine. Now I need to add a new not null varchar2 column "flag" which can be a Y or a N.
To do so, I created a new checkbox item p1_flag, set the source properties and the LOV definition to: STATIC2:Flag set;Y
However when I try to save the data with the checkbox unticked I get a null value error. To solve it, I created a computation on that field like this:
nvl(:p1_flag, 'N')
Is this the best way to do it? (other than using database triggers)
Thanks
Luis

Hi Patrick
Thanks for the reply. I thought that, just wondered if there were a better way...
Another option that I was thinking about was to modify the column definition to be nullable, with valid values being Y and null. So I wouldn't have to care about it. The only thing being that I don't like very much the idea of modifying the database design because of the development tool (though I saw things much worse than this, as using VARCHAR2 instead of DATE because the front end tool didn't handle date datatypes very well!)
Or just stick to a trigger to do it.
Cheers
Luis

How to create two or more Automated Row Fetch on 1 Page

Hello!
Please help me to create 2 ARF processes from 2 different tables but on one Page. Is it possible in Apex 4.0?
Thank you!

Hi,
Nope, i dont think so. If you want to make a form from only one table then use ARP. If you want to develop form based on two or three tables then write a custom pl/sql process of your own and you cannot able to use ARP.
Brgds,

How to get a single row fetched in a form?

Hi,
I would like to make a profile page , where the (currently logged in) user can change his adress, e-mailadress etc.
This page must have only a form with input fields, filled with data from the database that the user can change. A report is not necessary because the user may only see his own data.
I tried already several things, but i get allways a form with no data from the database, with the possibility to create records (sometimes, depending on what i choosed in the wizard, also an update button).
I also changed in the 'Automated Row Fetch' the property WHERE CLAUSE with :P9_ID = 1 and even with ID = 1, but both clauses doesn't make a difference.
(1 is the value of the ID-column in my table) // (:P9_ID is a field on my page, linked to the ID-column in my table) // (ID is the PK and columnname in my table)
Is this possible to make an input form containing existing data (that a user can change), and how?
Thx.

Hi,
Whats the table column which stores user login ID? lets say its APEX_LOGIN_ID then create a page item P1_APEX_LOGIN_ID and put default value to :APP_USER. Now in the ARF process, for "Item containing primary key value" put P1_APEX_LOGIN_ID and "Primary Key Column" to APEX_LOGIN_ID.
Cheers,

Row fetching, session state, multi-page processing of 1 row - problems

I'm building an application that's updating a couple of tables via an updateable view and an instead-of trigger. That portion of it works OK, EXCEPT for the problems that I'm having with the APEX end.
I've got 3 pages; the first page reads the row in via the automated row fetch and has, say columns 1-20.
Page 2 has, say, columns 20-40 and page 3 has the remainder.
I have the row fetch set up conditionally so that it only executes the first time that page 1 is displayed. All the columns are set as Database Columns.
It seems that if I fill in fields on page 1, move to page 2, and back to page 1, the contents of the fields on page 1 are destroyed unless I set their 'Source used' to 'Only when the current value in session state is null'.
Furthermore, upon update (which is on page 3, via an automated row update), the only columns that get updated are those that exist on page 3. The column values from the other pages no longer exist.
Does navigation to another page not retain the session-state of database-column items?
Am I better off just writing my own processes to perform the updates?
Any other suggestions?
Frank

Hello Frank,
>>I have the row fetch set up conditionally so
that it only executes the first time that page 1 is
displayed …
It seems that if I fill in fields on page 1, moveto page 2, and back to page 1, the contents of the
fields on page 1 are destroyed unless I set their
'Source used' to 'Only when the current value in
session state is null'.
It seems that the first sentence is not consistent
with the second one. The only reason the values are
destroyed, as you call it, is that the ARF is running
again. What condition are you using on your ARF?
In any case, the right way to deal with it is to
change the source used to "Only …", as I understand
you already did.
Hi Arie,
I set an item after the first ARF. I then have the ARF set to execute conditionally based on the presence of that item. (I also display a success message on the ARF, so I know that the ARF is only occurring once). I move to subsequent pages by submitting the current pages.
>>Does navigation to another page not retain the
session-state of database-column items?
Navigating to another page does retain the session state values.
It's depends on what you mean by navigating.
Submitting the page set/update session state.
Redirect without submitting the page will not
set/update the session state.
>>Furthermore, upon update (which is on page 3,
via an automated row update), the only columns that
get updated are those that exist on page 3. The
column values from the other pages no longer
exist.
Automatic DML is working only with the current page
items. You can't use it to insert/update other page
items, even if they are in session state. However, in
your case, it's not the Automatic DML performing the
actual updates, but your triggers. Are your triggers
relying on session state values?
I think this statement 'Automatic DML is working only with the current page
items.' answers my question. My trigger is working on session state values. It's an 'instead-of' trigger, so I was letting the automatic DML perform the 'update' on the view, while allowing the trigger to do the actual update of several tables that the view joins by referring to their :NEW. values in the trigger. Since the DML occurs on my last page, those were the only session state values that my trigger ultimately saw.
>>Am I better off just writing my own processes to
perform the updates?
I believe the correct way is to submit the page and
then branch to the next one. Submitting the page will
save all your items in session state, and allow these
items to be available for page 3 DML.
Regards,
Arie.I'm doing that already - all the values do appear to be in session sate, except only the items that are on the last page actually make it to the automatic DML update, which seems to agree with your previous statement.
I suppose I could write my own process to perform the update, as the values are available in session state.
Thanks,
Frank

BLOB column not updating using automated row processing

I have fiddled around with creating a simple application to understand how APEX handles images stored in blobs - did a simple app that stores them, gets them, displays them. it all works great.
so i have this existing table/application that i am trying to add a BLOB column to here's what i did:
it's a pretty simple form on a table with report application. just one table.
I added the BLOB to the table (and the other mimetype etc cols as well).
i added the page items to the form page.
i basically made everything identical in terms of page item settings and such to the working simple application.
so here's the problem... when i run the application and update a row, the BLOB column isn't updating. neither are the mimetype or filename columns. the activity date col is.
and here's another interesting thing. i quickly created another form and report pair on the same table, and when i ran it, it updates the blob col just fine.
why is my original form not updating it? what can i do to remedy this? any ideas? i've gone though setting by setting for the blob page item and the one that works is identical to the one that doesn't.
i'm using the automatic row processing to update the table.

Gary,
The DML processes (and the creation wizards for them) are for use with items having source type Database Column. If your page items don't use this source type, then neither the Automated Row Fetch nor the Automatic Row Processesing (DML) process types will work.
