The packaged procedures, subsidies and reports

My custom label warning: I'm a newbie, forced to be a generator of queries of database by need, please bear with my horrible explanations. I searched Google this until the end of google and can not find an answer to my particular problem, if I was able to solve many questions to get here - so, I'll try.

Now, I have determined that a NOTICE that I had written for purposes of end-user reports using crystals, our 11 g database, wasn't going to work. I needed to integrate date parameters IN the body of the view/query. So I thought I'd build myself a packaged procedure.

This works. It gives me the data I want (when I am logged in as owner of the schema).

HOWEVER - I now understand that the procedures work as seen in that, if I have specific tables selected, in the procedure, users who run it must have separate SELECT privileges on each table referenced in the procedure? I don't have to do it, with a view, aren't I right? If I build a view and a PUBLIC SYNONYM for this point of view, and grant SELECT to the role that users have, they can see the data.

And to continue that - I - I also understood I must grant EXECUTE on each individual USER privileges and cannot accomplish role, with a packaged procedure?

Thank you!

I don't know what you mean by 'embed' date settings.
There are ways to have a view depend of parameters, such as the view does not have to be recompiled when the parameters change. I wouldn't say that the settings are included in the view. In addition, different sessions can use the display at the same time, each (potentially) with its own parameters.
One way to store the parameters so that the view can refer to them is a global temporary Table.
(Variables SYS_CONTEXT is another, but for the DATE parameters, I think a global temporary table would be easier).

So I thought I'd build myself a packaged procedure.

This works. It gives me the data I want (when I am logged in as owner of the schema).

HOWEVER - I now understand that the procedures work as seen in that, if I have specific tables selected, in the procedure, users who run it must have separate SELECT privileges on each table referenced in the procedure?

There are 2 types of procedures: AUTHID DEFINE and AUTHID CURRENT_USER.
AUTHID DEFINE is the default value. When the tracks of the procedure, everything inside is done with the privileges of the owner of the procedure, so that the owner of the procedure needs the privileges on the tables, views, and other necessary procedures. The user who runs it must only EXECUTE privileges on the procedure itself.
AUTHID CURRENT_USER is as you have described above. One who executes the procedure needs privileges on all objects referenced in the procedure.

I don't have to do it, with a view, aren't I right? If I build a view and a PUBLIC SYNONYM for this point of view, and grant SELECT to the role that users have, they can see the data.

It's true. If, for example, they want to make reference to the view from their own point of view, or in the stored procedures, but no not just to use the view in queries, users need additional privileges. Notice that this is similar way privileges are dealt with in the AUTHID DEFINE procedures.

And to continue that - I - I also understood I must grant EXECUTE on each individual USER privileges and cannot accomplish role, with a packaged procedure?

No, EXECUTE privileges can be granted through roles.
Perhaps you are blend with the privileges of the object. If the procedure is AUTHID DEFINE, then the owner of the procedure must have all the necessary privileges granted directly, not by a role. This only applies to the owner; others who call the procedure just EXECUTE privilege, and it's okay if this privilege comes through a role.

I don't know very well your needs, but it looks like you want really a view and a way to specify settings that does not need to grant privileges to each individual user. If so, a view and a global temporary table to hold the settings, sounds like a good option. You can grant SELECT on the view privileges and all privileges on the global temporary table, in a role. users will no longer have this role.

If you want help, CREATE TABLE and INSERT to your base tables statements, two sets of parameters and the content of the display you want to see for each set of parameters.
Do you want the settings to default values? Give an example.

    Hi if your task is running an informatica mapping you can set your DAC task to run the full mapping for incremental and full loads, so tab task just point to the mapping.

    Yes, you can install all software from Adobe on 2 computers which are mainly used by the same person but not both computers at the same time.

    This allows you to install on your desktop for work from home / office and a laptop when away from your home/office. But you cannot use LR and PS on both computers at the same time.

  • Newbie - how to import the package, procedures, etc.?

    I used the "data export", the computer of the developer, expoty tables, export procedures, export Packages, etc. in a file
    SQL Developer.

    In Sql Developer, how to import tables, import procedures, import packages on my computer "REAL LIVE"?

    I want to copy the Package, the copy procedure, etc. 'computing Developer' to computer "LIVE REAL DATA?


    TIA
    Steve42

    If you have access to 2 databases of your sqldev client (and therefore have connections put in place for both of them), just run the export file obtained from the DB dev as a script (F5), using the connection to the production DB (drop-down menu at the top right).

  • Where is the download of forms and reports 11g Release 2 (11.1.2.0.0)?

    Hello

    I managed to download one of the facilities for Forms 11 g from here:

    http://www.Oracle.com/technetwork/developer-tools/forms/downloads/index.html

    However the readme it says it's a patch 11.1 . for version 2.1.0 11.1.2.0.0

    Now I'm a bit confused when I go on this page that show requirements:

    Oracle Fusion Middleware 11g system requirements

    There is a download tab, but it is not.

    So, where is the download of 11.1.2.0.0?

    Thanks in advance,

    Richard

    If you take a look at the XLS I gave you (http://www.oracle.com/technetwork/developer-tools/forms/oracle-forms-111210certmatrix-1886127.xls) it says:

    Oracle Forms and reports 11.1.2.1.0 is certified with WebLogic Server and 10.3.5 and 10.3.6.

    It is therefore your choice between 10.3.5 and 10.3.6.

    Thank you

    You must declare a variable of type T_CURSOR and pass it to the procedure like this.

    declare
  lOutCursor CURSPKG.T_CURSOR;
begin
  CURSPKG.OPEN_ONE_CURSOR(, lOutCursor);
end;
