How to limit the rows returned from the user role-based interactive reports

Hello

I'm a new Apex-PL/SQL Developer, looking for some recommendations on how to implement an interactive report to display different lines in your current application ROLE service.

For example let's say you have an application for orders and 2 different roles: superuser and sales-rep

Now, if super user connects to the application, it should be able to see all the rows in the orders table, however, if the user 'john' connects with the commercial list, he should see those orders assigned to him.

I don't think I can use "dynamic" sql and build my where clause on the fly if I choose an interactive report so I was looking around and came across the concept of a common function but it seems that some other people do this with collections of the APEX. Is there anyone with a recommendation for one to use? A few books I've read recommend putting most of the logic that you can on your database (easier to maintain in the long term) that's why I thought about pipep functions using, but I thought I would check with the experts first.

Thank you!

If you are allowed to use an Enterprise Edition database and to apply these restrictions, through the entire application, or across multiple applications, then use of private virtual database (DPV), with the security attributes of PL/SQL Code to the initialization/cleanup APEX application to set and reset the settings in your application.

Should you not use EE, then you can roll your own VPD use parameterized views.

If the restriction is only required for this unique IR, then, simply use a union of two mutually exclusive predicates opportunities:

select ...
from orders su
where :app_role = 'super-user'
union all
select ...
from orders rep
where :app_role = 'sales-rep'
and rep.salesman = :app_user

All of these approaches should outperform functions in pipeline, collections, or a user-defined function (which, in a predicate that is executed for each line, mudra stopped the large datasets because of context switching).

    The number of currently active sessions (db, internal sessions registered)

    to increase or decrease the maximum number of connections:

    for example: change processes control system = 200 scope = spfile;

    >

    V_$ Resource_Limit contains details of the sessions. Is this even for connections?

    I have more clarification on the difference of connections and Sessions.

    Connection means a user process is successfully connected to the listener to have a session on the database running instance. (listener who listen s new connection requests)
    Establish sessions: means, a (dedicated) server process began to serve a user process. It is done when the credentials of the user authenticated successfully. Now, from process-user shall communicate to the server process directly.

    hope that helps.

  • How to limit the length of the texts on iOS9?

    Hello

    I just worked on why I am required by my mobile / cell phone provider EA.  They charge any text as a picture message / SMS, it is longer than 120 characters?  Does anyone know how to limit the length of the texts / SMS so that it is impossible to send a more 120 characters or create an alert so that you are aware of the number of characters in the text / sms?

    Thank you very much

    Hello Turnus123,

    Thank you for using communities of Apple Support.

    I see that you will have to pay for SMS more than 120 characters.  To help identify messages exceeds this amount, you can activate a number of characters in the message settings.  Simply go to settings > Messages and activate "number of characters".

    Message settings

    Take care.

  • How to change the areas of region of report in read-only mode?

    How to change the areas of region of report in read-only mode?

    SKUD.

    Add fuction javascript after the page header (or section of function and Javascript variables)

    function disableItems(pRegionStaticId,pDisableFlag) {
  $('#'+pRegionStaticId).find('[name^=f]').each( function(){ /* matches fxx */
    if( $(this).attr('name').match(/f[0-9][0-9]/) ){
      return $(this);
    }
  }).attr('disabled',pDisableFlag);
}

    pRegionStaticId is static Id + the region

    Note that this code specifically disables only the berries of request. Disabled items are not available after the submission (and are therefore different from readonly). But any javascript page can change disabled or readonly points (client side), so you need to check on the side server to validate the data.

    You can disable items to help

    disableItems ("MY_REGION_ID", true);

    and allow them, by passing false

    disableItems ("MY_REGION_ID", false);

  • Somehow, I blocked my user account (login) and I tried to help but can't find any info. How to UNLOCK the user account. Than k you

    Somehow, I blocked my user account (login) and I tried to help but can't find any info. How to UNLOCK the user account. Thank you

    Hello

    Click the account icon that was locked and enter the password IF you know and otherwise:

    Try Safe Mode - several times, press F8 that you start. The Admin account there is no default password
    so unless someone has changed, you should have access there. Then Control Panel - accounts - users
    Manage another account - use this down your user account (to the lowest level) APPLY/OK
    then go back and reset it to the Admin APPLY/OK - this clearly allows corruption. Do this several times.
    Then fix the password in your usual account. Do not forget to leave your account administrator if you
    wish.

    If no joy Mode without failure:

    Try this - use the hidden administrator account to lower your user account (to the lowest level) APPLY/OK
    then go back and reset it to the Admin APPLY/OK - this clearly allows corruption. Do this several times.
    Then fix the password in your usual account. Do not forget to leave your account administrator if you
    wish.

    Make another Admin account with your password and use it to fix the others if necessary. (just for
    repair, don't use regular account, not a safety valve) always keep a spare ADMIN account.

    DO NOT LEAVE THE ENABLED LSA OR USE DAILY. If it corrupts you are toast!

    Summary:

    1 set the "New Menu" permission in the 'home page and Header' refusal, then the 'New' menu will disappear from the top right of the page, which prevents the user to create dashboards and new anlysis

    2. in order to not allow the user to modify the catalog, set the permission of "access user interface of the catalogue"in the ' welcome and header' to refuse."

    3. even made 1 and 2, we have always have a path that the user can create new report, it's "House"menu." To avoid this, our method is to set the explicit right to catalog for the application role.
