Double quotes in function and procedure names when using impdp

When viewing a function in the original database, it looks like:
CREATE OR REPLACE FUNCTION TA_ACTIVITY_D_GEN_FNC
After doing an expdp and impdp to restore a development database, it now looks like
CREATE OR REPLACE FUNCTION "TA_ACTIVITY_D_GEN_FNC"
and also has 2 blank lines at end of function.
This causes us problems when trying to use various utilites to compare differences in production and development. Now every function and procedure shows up as being different.
Can someone please explain why and what can be done to avoid this from happening?
Edited by: user6116705 on Jun 15, 2010 7:52 AM

from old exp, here is the first line of the create procedure statement:
CREATE FORMAT71 PROCEDURE "SECURE_DML"
You can see the double quotes. I don't understand why you wouldn't see the same compare issue with old exp. I was wondering what you were using for compare since it would let me know where to look for anything that has changed from the original create to the create performed by data pump. I remember there being an issue in this area. I just don't remember if it was extra spacing, upcasing, or something else or multiple changes. You could contact Oracle support to see if there is a fix and if it is backported to your version.
The only other way you can possibly fix this (and it would be a huge pain) would be to run impdp with a sqlfile and then edit the sqfile to remove the double quotes and to remove any extra spacing/extra lines. A patch from Oracle would certainly be easier if one was available.

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

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.

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.

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.

Specify the output file path and print name when printing pages

hi,
how can i Specify the output pdf file path and print name when i am using the function PrintPagesSilent from AcroAVDoc Object.
My Code :-
Acrobat.AcroAVDoc doc = new Acrobat.AcroAVDoc();doc.Open(path,
"temp");

Dear Irosenth,
i try with different format (doc, docx, xls, jpg, bmp and txt) and it working successfully, but it give an random name for the file which saved in default folder for Adobe PDF print.
you can use the following function:
private void PrintPDF(string[] inputfilepath){
foreach (string path in inputfilepath){
Acrobat.
AcroAVDoc doc = new Acrobat.AcroAVDoc();doc.Open(path,
"temp");
Boolean v = doc.PrintPagesSilent(0, ((Acrobat.AcroPDDoc)(doc.GetPDDoc())).GetNumPages() - 1, 0, 0, 1);doc.Close(1);
and calling it by the following code:
PrintPDF(System.IO.Directory.GetFiles("c:\\t\\printjob"));
copy all files that you want to convert in side the mentioned path and run it program, then check the defualt print path for Adobe PDF printer.
test it and reply me. thanks again

Use of function and procedures

when we need to use function rather than procedure or viceversa???

Welcome to the forum!
Use a function if you want to use the value it returns as you would use any other expression in a SQL statement:
SELECT SYSDATE
,       my_function (column1) AS c1
,       UPPER (column2)        AS c2
FROM    table_x;or in PL/SQL:
IF my_function (x) > 0 THEN ...Use a procedure otherwise; for example, if there is no value to be passed back.
Functions can have OUT (and IN OUT) arguments, but they can cause confusion. Many people use procedures whenever they need OUT arguemnts, which includes all situations where 2 or more values are passed back.
Any good book or site on PL/SQL, or any kind of procedural programming, should explain the differences between functions and procedures.
If you don't have at least that much guidance, it's better not to try using PL/SQL.

Calling Oracle function and Procedure using OCCI with in C++ code

Could any body send me the sample code to create and execute Oracle function and Procedure using OCCI concept in C++?.
Edited by: 788634 on Aug 16, 2010 4:09 AM

Hi Vishnu,
Yes, sure, you can create a PL/SQL procedure, function, package, package body, etc. from within an OCCI application. I would say that, generally, this is not the sort of activity a typical client application would perform unless there is some initialization/installation processes that need to happen. In any case, here is a simple demo showing how to create a stand alone procedure (in a real application I would use a package and body) that returns a ref cursor. The ref cursor is just a simple select of two columns in the hr.countries sample table. Of course, there is no error handling, object orientation, etc. in this demo - I wanted to keep the code as short and as simple as possible to illustrate the concept.
Regards,
Mark

// database connection information
string user = "hr";
string passwd = "hr";
string db = "orademo";
// sql to create the procedure which returns a ref cursor as out parameter
// should be run as hr sample user or in a schema that has select privilege
// on the hr.countries table and a synonym (countries) that points to the
// hr.countries table

    "create or replace procedure get_countries(p_rc out sys_refcursor) as "

    " select country_id, country_name from countries order by country_name; "
    "end;";
// pl/sql anonymous block to call the procedure
string sqlCall = "begin get_countries(:1); end;";

env = Environment::createEnvironment(Environment::DEFAULT);

// create the procedure
stmt->executeUpdate();
// terminate the statement object

stmt = con->createStatement(sqlCall);
// need to register the ref cursor output parameter
stmt->registerOutParam(1, OCCICURSOR);
// call the procedure through the anonymous block

Extracting package and procedure name in code

In my exception processing I need to log the package and procedure name that got the exception. How do I obtain these two names without manually coding the names?
Thanks in anticipiation

A better option is to get the package name and the line numberA still better option is to utilize pl/scope (when you are in 11g (not sure about 10g)):
SQL> alter session set plscope_settings='identifiers:all'
Session altered.
SQL> set serverout on
SQL> create or replace package pkg
as
   procedure p1;
   procedure p2;
end pkg;
Package created.
SQL> create or replace package body pkg
as
   procedure get_scope (obj varchar2, line int)
   as
   begin
      for c in (select rpad (lpad (' ', 2 * (level - 1)) || name, 20, '.') || ' ' || rpad (type, 20) || rpad (usage, 20) identifier_usage_contexts
                from user_identifiers t
                where level != 1
                start with line = get_scope.line and object_name = obj
                connect by usage_id = prior usage_context_id)
      loop
         dbms_output.put_line (c.identifier_usage_contexts);
      end loop;
   end get_scope;
   procedure p1
   as
   begin
      null;
   end p1;
   procedure p2
   as
   begin
      get_scope ($$plsql_unit, $$plsql_line);
   end p2;
end pkg;
Package body created.

In built functions and procedures

Hi,
Would someone be able to tell me where i could find the in built functions and procedures within the OWB directories. I am trying to determine the methodology used to write custom procedures and functions within the OWB mapping.
Thanks

Hi,
I have written a very simple function that returns the row count from a table called TIMEDIM but the mappings validates fine only that the ouput is blank.
I have attached the code i used :
v_total NUMBER (10);
--initialize variables here
-- main body
BEGIN
SELECT COUNT (*)
INTO v_total
FROM TIMEDIM ;
-- allow compilation
RETURN v_total;
EXCEPTION
WHEN OTHERS THEN
NULL; -- enter any exception code here
RETURN NULL;
END;
any help would be greatly appreciated.
Thanks

Doubts in Functions and Procedures

Hi Everybody,
Can anybody tell the exact differences between function and the Procedure?
My doubts are
1. if procedure can return, and not necessary that it has to return a value,(that means if we want to return and doesnt also we can write procedure) then why do we need function?
2. I tried to call a function which updates one table in the code,, i got an error saying that the function should not use DML.
3. I want to know the combination that
a. can procedure call a function and viceversa?
b. can function (which uses DML statements)be called from sql statement ?
and if any other combinations are there let me know with reasons.
Thanks in advance,
Vinay

To elaborate on the already correct answers...

My doubts are
1. if procedure can return, and not necessary that it has to return a value,(that means if we want to return and doesnt also we can write procedure) then why do we need function?Procedures and Functions are self contained blocks of executable code. When that code completes it has to "return" to whatever called it, so both Procedures and Functions do return, however a procedure has an implicit return when it reaches the end of the code (or you can specify the keyword RETURN without any value if you like), whereas a function must contain a RETURN keyword before reaching the END keyword and a value of the correct datatype must be returned by that RETURN keyword.
Functions must return a value, whereas Procedures do not return any value.
If values need to be passed back from a procedure then OUT or IN OUT parameters are used, however if values are to be passed back then often it is something that should be considered for being a function rather than a procedure.
Functions may also contain OUT or IN OUT parameters, but these types of parameters limit the function to use within PL/SQL code only and prevent them from being used in SQL, as the SQL engine will have no variable to pass back the OUT value into. Generally it is considered bad practice to use OUT or IN OUT parameters in functions.
The underlying internal differences of Functions and Procedures comes down to how values are passed in and returned via the internal stack or via memory references where the parameter is specified as an OUT / IN OUT with NOCOPY. If you're not familiar with writing machine code / assembly language or low level C code, then this concept will probably be alien to you and it will take more than a simple post to explain it.
2. I tried to call a function which updates one table in the code,, i got an error saying that the function should not use DML.Functions can contain DML, but those functions can only be used from a PL/SQL call to it, not from within a call from an SQL DML itself. i.e. a DML cannot contain further DML.

Function and Procedure

Hi Friends,
My Question is : At what time we will use function and Procedure.? How i can prefer it?
Regards,
Anu

Functions are normally used for computations where as procedures
are normally used for executing business logic.
there can be many difference between stored procedures and functions
main are
1. function can be used in the SQL statements anywhere in the WHERE/HAVING/SELECT section where as Stored procedures cannot be.
If you have a function in which there are DML statements only then you can not call this function in a SQL query
for example
For example, if you have a function that is updating a table, you cannot call that function from a SQL query.
- select myFunction(field) from sometable; will throw error.
But you can do it through procedure.
I hope it is clear

Ipod will not display track and artist name when i play a song

ipod will not display track and artist name when i play a song... i cant see the the volume display to adjust it eiether. Everyting shows up in the menus just not on the now playing screen.... any suggestions?

Try restoring your iPod. Just be aware that restoring will erase the hard drive, reload the software and put it back to default settings. Once the restore is complete follow the on screen instructions and it should connect to iTunes and give you a prompt to automatically update your library onto the fresh installation. If you want to update manually or using selected playlists choose no and it will default to manual mode and you can choose whatever setting you like: Restoring iPod to factory settings with iTunes 7

Same algorithm in function and procedure then which one will better?

Why pl sql function is better to computes a value instead of procedure?
If I apply same algorithm in function and procedure then which one will perform better?

It's not a matter of performance, it is more a matter of how it is going to be used.
A function can be used as an expression in an assignment or in a query.
my_var := my_func(my_param);
select my_var(my_col) from my_table;But it can just return a single value (which can be a complex value like a nested table or object or ref cursor, but still a single value.)
The procedure often is more used to perform an action that does not return anything.
execute_invoicing(my_invoice_id);Or procedures can be used if you need multiple return values.
my_proc(my_input, my_output_1, my_output_2, my_output_3);But the procedure cannot be used in an assignment expression or a select query.
Performance wise procedures and functions are completely identical. It is only a matter of what action they perform and how you are going to use them.
