APP_USER in v$ tables?

We are using custom authentication. Basically a big app user for login. I would like to be able to interrogate tables like v$sql v$sqlarea... Is the apex APP_USER available somewhere in the v$ tables for me to see who is running what query? Thanks
Jon

Just an update. Looks like I found what I was looking for in v$session.client_info.

Hi Scott,
I am facing the same problem. I have created one application process with process condition On New Session: After Authentication. In this application process i am checking for :app_user in particular table, if the person does not exist i am inserting a record in to the table. But every time :app_user is having null value with On New Session: After Authentication process condition. It is working fine for remaining process conditions.
Thanks in advance for your help

Display PL/SQL funtion output in HTML Region dynamically

I have a form/report with just 2 items (one is hidden). When I click on the displayed field, I would like the output of a function/procedure (with the form/report field as argument) to display in a region on the same form. I already have a function with varchar2 as return value and also a procedure that prints out html output through htp.p package.
But couldn't figure out how to connect the form and the region and be in sync.
I have a chemical structure data stored as CLOB in the DB with an ID. Basically, clicking on the ID should pass the CLOB to the procedure that outputs the <embed and so on tags for a plugin to display my chemical structure.
Any help/guidance is appreciated.

Hi Carl,
Thanks for the post. I tried the static value and it works (structure displays). My problem is for it to pickup on the value of my field.
I could give you my login credentials on htmldb but I am not sure if that would help as you would need the plugin installed on your browser (frre version may be available at www.mdl.com and search for "chime").
I have something along these lines in procedure.
htp.p('Hello World, I am ' || :APP_USER);
htp.p('<table border=1 cellpadding=1 cellspacing=0 width=550><tr><td align=middle valign=top>');
htp.p('<input type=hidden name="queryrxn" value = "'|| :MOLCHIME ||'">');
htp.p('<embed type=chemical/x-mdl-molfile width=300 height=100 queryformbox="document.query.queryrxn" structure='''||:MOLCHIME||'''></td>');
htp.p('</tr></table>');
Thanks for any input.

Best practice for VPD and remote tables

Not specifically an HTMLDB question, but here goes...
HTMLDB 1.6 on 9.2.0.4 connecting over database link (fixed username/password) to 9.2.0.4
I've currently "wrapped" access to the remote tables in views, i.e. view "T" in the HTMLDB parsing schema LOCAL_USER is defined as "SELECT * FROM T@remote"
I'd like to put VPD controls on my backend tables, but I don't get how v('APP_USER') (or even APP_USER put into an application context) would be seen by the remote database.
Should I just put VPD policies on LOCAL_USER's views and call it a day?
Thanks for input!
-John

If you implemented the VPD in the remote database, what would your VPD be restricting? All queries would apply the policy based on the DB link fixed username resulting in all users of the HTML DB application having same policy restrictions.
The policy in the remote database does not has access to the value of v('APP_USER'). That value is only available in the database that has HTML DB. You would have to write APIs in the remote database in PL/SQL functions/procedures to pass in the V('APP_USER') value to the remote database. This is doable, but cumbersome.
If you want to have your policy modify your WHERE clause on the fly based on your HTML DB user account, then I would implement the VPD in the database which has your HTML DB repository. I am not sure which of the two scenarios below occur when doing a SELECT * FROM T.
1.) The query goes across the database link, gets all the data out of table T in the remote database, passes back to the HTML DB database, and applies the policy WHERE clause modification in the HTML DB database.
2.) The query applies the policy WHERE clause modification to the view, goes across the database link with the WHERE clause modified, and gets only the data allowed based on the policy from the remote database.
You should test this out to find out for performance purposes what query is actually performed on the remote database.
As always if anyone sees anything inaccurate in what I have written, please correct me.

Returning multiple values from a table

Hi there i am working on a bit of sql which will return values when they exist in a table.
The code I have returns the correct value when there is only one entry in the tbl_studentmodules table, as soon as there is more than one entry in this table it displays no rows at all :(.
Can anyone point out how I go about returning multiple values?
             select modulename from tbl_modulefeedback
where 1 = (select count(*) from tbl_studentmodules
       where upper(:APP_USER) = upper(student_id))
and 1 = (select count(*) from tbl_modulefeedback, tbl_studentmodules
      where tbl_modulefeedback.modulecode = tbl_studentmodules.modulecode)Thanks in advance!
Ashleigh

I'm not quite sure I understand what you are looking for, but I think a simple join may be what you need. something like:
select modulename
from tbl_modulefeedback mfb
   join tbl_studentmodules sm
      on mfb.modulecode = sm.modulecode
where upper(sm.student_id) = upper(:APP_USER)This will return the module name for all modules that the given student has provided feeedback for. If there is a possibility that a student/module combination could appear in tbl_studentmodules more than once, something like this might be better to show the modulename only once.
select modulename
from tbl_modulefeedback mfb
where mfb.modulecode in (select sm.modulecode
                         from tbl_studentmodules sm
                         where mfb.modulecode = sm.modulecode and
                               upper(sm.student_id) = upper(:APP_USER))If this is not what you want, then post some sample data (preferrable in the form of insert statements or a with clause) and the results you expect rom that sample data.

Tabular Form - How to store in a column the User details (APP_USER)

Hi all,
I have let's say the following table:
USER_COMMENTS(
ID number primary key,
COMMENT_TEXT varchar2(50),
POSTED_BY_USER varchar2(50),
DATE_POSTED date,
UPDATED_BY_USER varchar2(50),
DATE_UPDATED date)
How do I, using a Tabular Form, get the USER details in the columns POSTED_BY_USER and UPDATED_BY_USER and the SYSDATE in DATE_UPDATED...
I've tried the following:
Created tabular form, all fields included. In Report Attributes > edit UPDATED_BY_USER > Display as Display as Text (saves state); Default Type: Item (application or page item); Default: APP_USER.
It's not working.
Thanks!
Andrei

It has to be a text field column type with source like the other updatable columns. You should hide that column and create a second of display as text if you want to show the content. Once this is done then you can use the default value and just type the item name there as you did:
P1_ITEM

Multiple Users sharing one Table

Hi Folks,
I'm a newbie with Apex so please treat gently ;-)
Simple "order entry" application: a table for Orders and another table for Order Items. All pretty run of the mill so far,
but instead of one end user (say the vendor company's telephone operator) typing in orders over the telephone for
several customers, consider opening the application to the several customers so that they can type their own orders
themselves.
The collection of Customers isn't that large (say about 12 or so), hence I'm thinking of just giving them distinct Apex logins
to the application.
I can pickup the login name from APP_USER, but how to copy this in behind the scenes to "customerID" in the Orders
table - the "customerID" field does represent a column in a database table, but I want to force it to the Apex login name
for whatever customer that is attempting to insert a new order.
All the Apex demo stuff shows simple order-items solutions; I'm trying to have a single Orders table with a column in it that tells
me which customer sent in this order, and for the customers using this table to only see their own orders from the same table.
If I was implementing this on the database I would use some sort of View such as "select * from orders where customer = user",
therefore every user would only see their bit of the orders table.
But how to implement this in Apex?
Suggestions and comments gratefully welcomed,
Thanks in advance

What this lacks is the "essence" of the task - I have to reverse engineer each blooming step to try and

Can you tell that I'm frustrated by a lack of documentation; I risk losing your kind support in my early
foray into Apex (help a drowning man please :-)
Thanks again in advance
Mungo :-)Its important to remember that Apex is nothing other than a framework for creating HTML and running web pages. So what used to be triggers are now standard javascript events. Although you will find help on the forum for javascript and maybe some in the documentation, javascript events are standard and not proprietary like Forms triggers were. Its frustrating, but there are a TON of resources (google) on the basics of javascript. For instance instead of when-validate-trigger, you'll probably look at the onblur event to trigger a piece of javascript code to run your validation. You can use onfocus which would be sort of like when-new-item-instance in Forms-speak.

How can I get ALL the user info from WWW_FLOW_FND_USER -table?

Hi.
I use HTML DB authentication and therefore all my user information is stored in HTML DB tables. I can use :APP_USER to get USER_NAME, but in my application I need to have also USER_ID, FIRST_NAME, LAST_NAME and EMAIL_ADDRESS fields from database. I don't want to change any database/schema security level so I cannot read directly from WWW_FLOW_FND_USER -table when I am inside in SCOTT -schema/sec.level.
How to read all the information?

Thank you for your help, but I cannot find any information about backage wwv_flow_user_api on OTN or in HTML DB documentation.
Where to start?

Help with uploading an excel file to a table using an application

Hello,
Can anyone please help me out with this issue. I have apex application where in the end users upload an excel file to a table. For this I have followed the solution provided in this link
http://avdeo.com/2008/05/21/uploading-excel-sheet-using-oracle-application-express-apex/
Using the above solution, I was able to upload the excel data to a table "sample_tbl1" successfully with fields Id,acct_no,owner_name,process_dt. But the thing is I want accomdate a particular condition while uploading the file data, to check see if the acct_no already exists in another table say "sample_tbl2" or not.

Can anyone please help me, how do i accomdate the condition within my existing code.
thanks,
Orton

Orton,
From your code it appears that the account No comes in the second column of the file = > v_data_array(1)
So You can put a conditional block around the execute immediate code that inserts the records
For instance
SELECT count(1) INTO ln_account_no_exists from <"sample_tbl2> where account_no = v_data_array(1);
IF ( ln_account_no_exists > 0 ) THEN
 --Account No: already exists
 <Do what you want to do here >
ELSE
 EXECUTE IMMEDIATE ...
END IF:
{code}
Inorder to handle the account no records which exists you can
<li>Raise an exception
<li> Write record to table or insert into collection and then use a report region in the page based on this table/collection to show error records
<li> Append errored account No:s to the Success Message Variable programmatically(this variable is used by PLSQL process success/error message )
 {code}
 IF ( record exists)
 apex_application.g_print_success_message := apex_application.g_print_success_message||','|| v_data_array(1) ; -- Comma separated list of errored account no:s
 ELSE ...
 {code}
Hope it helps

Insert values to one table based on a value inserted into another table

Hi,
I've got a form based off a report which creates a new project. I've added an additional process to this form to insert four new values into another table as soon as the new project is created and the PK for that project is generated. This was working last week (of course!) and now seems to not work at all. It's complaining that the PK I was getting from my first insert was null. Here is one the the statements in my process I'm trying to run:
insert into week_group values(week_group_seq.nextval, (SELECT trunc(NEXT_DAY(SYSDATE, 'FRIDAY')) FROM dual), 0, '', :P45_PROJECT_SEQ, sysdate, :APP_USER);
The complaint I get that it's getting null where :P45_PROJECT_SEQ should be.
Thoughts?
Thanks,
Jon

Hi Andy,
Thanks for the tip. Those two values didn't match and I updated them so they do and I'm still getting a "cannot insert NULL..." error.
When I turn on debug I see that I'm getting the PK and I see the value. Here's my debug output:
0.24: ...Process "Get PK": PLSQL (AFTER_SUBMIT) declare function get_pk return varchar2 is begin for c1 in (select PROJECT_SEQ.nextval next_val from dual) loop return c1.next_val; end loop; end; begin :P45_PROJECT_SEQ := get_pk; end;

I notice that when it runs my process "Add Week Groups" it's not displaying all of the SQL. But the SQL is fine, it's right here:
insert into week_group values(week_group_seq.nextval, (SELECT trunc(NEXT_DAY(SYSDATE, 'FRIDAY')) FROM dual), 0, '', :P45_PROJECT_SEQ, sysdate, :APP_USER);
Hmmm....what about the "reset page" action in the last of the 0.26 lines?
Thanks,

How to conditionally display a tab (or not) based on APP_USER?

Hi,
I want to put a condition on the display of a tab based on the value of APP_USER. There are two columns in the table and APP_USER must exist in one of these two columns in order for the tab to display. If APP_USER isn't in either of these 2 columns, the tab does not display. These 2 columns are different levels of management, and if the user isn't a manger, I don't want the tab to display.
Another requirement: APP_USER will be [email protected], but the values in the table are only firstname.lastname. So, I need to do a rtrim of APP_USER to remove @email.com.
I've tried several options, but can't seem to get it right. Suggestions?

From a database design aspect, that is a bad design. You should really create a column called "role" and then put the values in that column, ie Unlimited, limited, manager, user, readonly, etc.
then you queries would be:
select * from SH_EMPLOYEES where upper(USER_NAME) = upper(:APP_USER)
and role="Unlimited".
Else you will have to create a column for each new role you need. You really want to avoid using column name that are "intelligent". It doesn't make for a flexible design.

APP_USER in v$ tables?
