How to move functions and procedures from packages into a schema?

Hello,
I have below requirements for a homework and my question is if someone can point me in the right direction to find documentation which can help me solve the below. Any information will be very much appreciated. Thank you.
Write procedures and functions (included or not in packages)under the form scripts .txt or .sql . Once they have been launched in SQL developer they should more the functions and the procedures from the packages in the current schema. If the current schema contains only 2 packages, pac1( with procedures p11,p12 and the functions f11,f12,f13) and pac2( contains the following procedures p21,p22,p23 and the functions f21 and f21( overloading cases), the execution of the scripts will generate the following effects:
The procedures p11,p12,p21,p22 ,p23 and the functions f11,f12 and f13 will be created in the current schema.
pac2 will contain 2 instances of the overloading function- f21; they will be kept in the package, without being created in the current schema; so all the procedures/functions overloaded will be kept in the original packages
If pac1 contains variables, cursors and public types, we will keep only the package specifics( and delete the body);generally if the packages do not contain procedures or functions overloaded the body will be deleted and if no variables, cursors, public types then we will delete the header.
If in the triggers, procedures, functions we will call procedures/functions from the packages(the procedures and the functions moved in the current schema) they reference will need to be updated ( via amending the body or recompile) for example if pa1.p12 will need to be replaced with p12.
The scripts will have to have numbers in the following series( 01....n) and characters that explain the content.

My only advice would be to remember that these are public forums and if YOU can find them, so can your instructors.
Also, those are horrible procedure and function names
This assignment seems to be around overloading pl/sql objects and order of precedence...do a search on the Oracle Docs around overloading and inheritence

How to move contacts and messages from Samsung Galaxy S3 to iPhone5?

How to move contacts and messages from Samsung Galaxy S3 to iPhone5?

As long as you had the Android data synced with your Google account, they should be there when you sync it on your new phone. That is by far the easiest way.
I think there is also an import/export option when you hit the menu button in the contacts app. and you could export them to SD card and import them on the new phone using the same SD card.
Or you can use Mobile Transfer to transfer data between Android smartphone. It is really simple, follow this guide to move contacts from Samsung S3 to iPhone 5.

How to find function and SP from data dictionary?

For example:
create or replace package SPK_A is
lv_empno number;
lv_deptno number;
function FUN_A(in_empno number) return varchar2;
function SP_A(in_deptno number) return varchar2;
end;
Then, how can i to find FUN_A and SP_A from data dictionary.
and mark the former is a function, the latter is a stored procedure.
I have tried to use the following 2 views, but i cannot give me the answer.
(1)dba_procedures: it can only find the sole function or sole stored procedure, which is not define in a package.
and it can not distinguish between function and SP.
For example, it can only find the function or SP as below:
create or replace function FUN_OUT return number is
begin
null;
end;
(2)all_arguments: it can list all function or SP which has varibles, but can not distinguish between function and SP.
Can anyone help me?
Any ideas appreciated.
Merry Chirstmas!

Is this what you mean?

Running SQL Server Function and Procedures from Oracle

I am trying to run SQL Server 2005 functions and/or procedures from a SQL statement in Oracle. I have gone throught the hetergeneous services and have connected to the SQL Server database successfully. I can also do a query to a table in SQL Server successfully; but I have not been able to execute a procedure or a function.

Have you tried Oracle syntax? It seems to me that you have only tried T-SQL syntax, e.g. execute proc.
Wrap it in a begin..end tag like you would a normal PL/SQL function or proc call. Assumption is that as Oracle makes the remote database (via the dblink) look like an Oracle database, you should also play along and pretend it is one and treat it as such.
E.g.declare
r integer;
begin
-- execute remote proc
procFoo@dblink( 'ABC' );
-- call a remote function
r := funcFoo@dblink( 123 );
end;

How do I copy and paste from Word into Adobe Photoshop Elements 13

using Windows 7 Professional SP1, Microsoft Office 365 (Office 2013).
I can copy the text within a word document, without a problem.
However, the paste options are greyed out and "Ctrl"+"V" does not work.
Am I missing something, as I can't work out how to copy the text from word, to use as a basis for my photo shop document.

Hey, guys. I am a complete noob to Elements 13. I need to get something done relatively quickly and I need to learn how to copy and paste from a Word document. How do I do this?
Copy the text in WORD to place it on the clipboard
Open PSE in Expert tab
Open your picture file
Get the type tool out of the tool box, click an insertion point
Go to Edit>paste
You should see two layers in the layers palette: background layer, and layer with the text.

How to move styles and actions from PS CS3 to PS CC

I have just signed up for Adobe Creative Cloud and Photoshop CC is downloading as I type this. I have been using PS CS3. I don't have a lot, but I do have a few styles (blending options) that I have used in a number of PS files. I also have a few actions set up. Is there some way to export/import these for use in PS CC? I have not yet un-installed CS3.
Thanks!

Does anyone know how to move a .mp4 file from flixter into iTunes?

I have downloaded a digital copy of a movie that I received when I purchased a Bluray disc. Most of the time, these go directly into iTunes, but this one went into Flixter. It is an .mp4 file. I tried using Add File to Library, but it didn't work. Any suggestions?
Thanks!

How to use type, packages, functions, and procedures in another schema ?

I have two target schema in one OWB project, such as A and B. In a mapping of A, I would like to use some types, packages, functions, and procedures from B. I have tried the method of synonym as suggested, but I could not find the metadata of these when importing ... The only type of synonym I can import is the synonym for table. Is there a bug for synonym?
If I cannot use synonym for this issue, is there another way to solve the problem?

Now, in some instances you will absolutely need to create the second module as Carsten describes, however it should also be noted that you can reference objects in things like Expressions even if you have not loaded up the metadata. It is only when you need strong binding that it becomes neccessary to import objects. For everything else, as long as the reference will resolve at compile-time then you are good to go.
For example, I have a function in one target schema (S1) and a private synonym to it in another(s2). A mapping in the S2 schema has an expression object that uses the synonym to the function in the expression property for a couple of the output attirbutes. The synonym has not been loaded into metadata - indeed OWB has no knowledge of its existance. But it resolves at compile time so the mapping validates and generates successfully.

Oracle Form functions and procedures in APEX, how?

I am working to recreate in APEX, already existing Read Only Forms in Oracle Forms. APEX Interactive Report functionality among other things, makes it worth while as well as targetting a different audience than the one that utilizies the Oracle Form versions. Oracle Forms versions use lots of pre and post query triggers, PLSQL Functions.
In Oracle Forms one of the places those functions can be located is in the "Program Units" section of the Form. A typical function of this sort, based on a specific Mission ID Itinerary, collects scheduled passengers last names, formats them with a comma and space after each one, into a single string that is returned and displayed as the passenger list of one row.
I have all this code written so I can move most of the main query of the Oracle Form into an Interactive Report. These functions and triggers called from within the Form, from the "Program Units" section of the Oracle Form rather than being stored in the Database schema in a package, where would they go inside APEX? Can I create a "Shortcut" in APEX and call it from the Interactive Report "Region Source"? Can I create the PLSQL function at the page level or region level of the Interactive Report? Or, is my best bet creating a package stored in the database, of all these functions and/or proecedures I may need from the original Oracle Form?
Some advice would be greatly appriciated.

I don't think I have been clear enough in describing the specific thing I want to do, it simply does not reach the level of forms to APEX conversion. It is basically a PLSQL Function problem.
I have an Interactive Report that is currently getting 90 percent of what I want however, each row, representing a Mission may have multiple legs. Each Leg has two locations or ICAO codes attached to it. Based on the Mission number, I want to loop through the leg table, collect all the ICAO codes for that Mission, put them all into 1 variable separated by a coma and add that variable to the column display of that Interactive Report as the last column.
In Oracle Forms I have a function saved to the database that is called within the main query. Maybe I am asking a question that does not need to be asked but in any case my question is can I put that function currently in the database somewhere in the confines of the Interactive Report and reference it via Http somehow or should I just stick with putting functions and procedures in packages stored in the database and called the conventional way?You could move the function to the database and call it from the report query, but it sounds as if it's superfluous. In the report query use whatever form of Re: 4. How do I convert rows to columns? is appropriate to your (unspecified) database version.
When you have a problem you'll get a faster, more effective response by including as much relevant information as possible upfront. This should include:
<li>Full APEX version
<li>Full DB/version/edition/host OS
<li>Web server architecture (EPG, OHS or APEX listener/host OS)
<li>Browser(s) and version(s) used
<li>Theme
<li>Template(s)
<li>Region/item type(s) (making particular distinction as to whether a "report" is a standard report, an interactive report, or in fact an "updateable report" (i.e. a tabular form)
With APEX we're also fortunate to have a great resource in apex.oracle.com where we can reproduce and share problems. Reproducing things there is the best way to troubleshoot most issues, especially those relating to layout and visual formatting. If you expect a detailed answer then it's appropriate for you to take on a significant part of the effort by getting as far as possible with an example of the problem on apex.oracle.com before asking for assistance with specific issues, which we can then see at first hand.

Data dcitioany view and function and procedures insure a package

I need the run a query on the Data dcitioany, to get a list of packages as well as a list for procedures and functions inside on Oracle 10g

I use DBA_SOURCE,
I used like this
SELECT v.owner,
       (CASE V.type
        WHEN 'FUNCTION' THEN NULL
        WHEN 'PROCEDURE' THEN NULL
        ELSE v.name
        END
       )PACKAGE_NAME ,
        UPPER(
        SUBSTR
        TRANSLATE(
        LTRIM(REPLACE(SUBSTR(ltrim(v.text),LENGTH('PROCEDURE')+1),'"',''),' '),
        '+++'
        ),---TEXT TO BE SEARCH
        1,---STARTING POSITION
        INSTR(
        TRANSLATE(
        LTRIM(REPLACE(SUBSTR(ltrim(v.text),LENGTH('PROCEDURE')+1),'"',''),' '),
        '+++'
        ||'+'
        '+'
        )-1 ---lENGTH
        )OBJECT_NAME
        TRIM(SUBSTR(ltrim(v.text),1,LENGTH('PROCEDURE')))"TYPE"
FROM dba_source v
WHERE (TRIM(ltrim(v.text)) LIKE ('FUNCTION%') OR TRIM(ltrim(v.text)) LIKE ('PROCEDURE%')) AND
            v.type IN ('PACKAGE','FUNCTION','PROCEDURE')
ORDER BY V.OWNER,V.name,v.text;Note: the translate, substr, etc function can be simplified based on your needs
in my case, how developers created the function and procedure is quite messy.
thanks

Query for getting all function and procedure inside the packages

hi All
Please provide me Query for getting all function and procedure inside the packages
thanks

As Todd said, you can use user_arguments data dictionary or you can join user_objects and user_procedures like below to get the name of the packaged function and procedure names.
If you are looking for the packaged procedures and functions source then use user_source data dictionary
select a.object_name,a.procedure_name from user_procedures a,
user_objects b
where a.object_name is not null
and a.procedure_name is not null
and b.object_type='PACKAGE'
and a.object_name=b.object_name

Assemble Web Services from database functions and procedures?

Web Service Assembler can assemble Web services from PL/SQL packages.
Can it be used to assemble Web services directly from functions or procedures?
Thanks,
Jim

Hi,
No, it relies on a package and takes each of the publishable functions and procedures as the web serivce methods.
Have you also tried using JDeveloper? It uses WSA under the covers but gives you a great GUI for selecting and working with your code
