Compiling Packages, Functions, and Procedures Issues

If you are in the editor for a package and attempt to compile a know good package under another schema (compiled in SQL+ and Toad), you receive the following errors:
Error(21,5): PLW-06002: Unreachable code
Error(131,7): PLW-07202: bind type would result in conversion away from column type
(122) TN_EXISTS NUMBER := 0;
(131) IF TN_EXISTS > 0 THEN ...
When commenting a line with if you have something like the following it tells you there is a syntax error
-- some comment here --
When compiling a PL/SQL function that returns a Boolean, you get this error: Error(40,4): PLW-06002: Unreachable code

Kris,
I seem to have the same problem.
Is there a way to 'deactivate' this behaviour, or do we need to wait for another Raport Release.
This is basically preventing me from using Raptor at all for any PL/SQL development ;-(

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.

How to call package function and procedure by PL/SQL

Dear all,
I created a package and I want test it by a select statement. e.g. select packagename.function(1, 'A') . However, there is an error message. "ORA-14551: cannot perform a DML operation inside a query ".
In the package, there is a function and I passed two parameters to the function and return a number. These two parameters will be used in the cursor select statment. Is there sth wrong that I use the cursor with the parameters? What can I do then?
On the other hand, I want to test the package procedure by using select statement in SQL Plus. How can I call it (with parameter)?
Remark: I am using Oracle 8i.
Thanks for advance!!

Hi!
I don't know why it is not running in ur computer. Pls check the script --
SQL> ed
Wrote file afiedt.buf
1 create or replace package pack_test
2 is
3    function try_test(eno in number,depno in number)
4    return number;
5* end;
SQL> /
Package created.
SQL> create or replace package body pack_test
2 is

4    return number
5    is
6      saln number(10);
7    begin

Invalid packages, functions and procedures

Hi,
Ok, I think I screwed up. Maybe someone can help me.
Our dev db which I just created a few days ago is 10.2.01. I was reading to see what needed to be done to this base for it to accept a 9.2 version. Data. I came upon oracle documentation that said to run the catalog.sql script. This had something to do with the Import full database and export full database procedures, they had to be added. So I did. I then noticed all these packages, procedures and functions listed on my oem tool as invalid. To correct this problem I ran the following scipts several times
On individual schemas: EXEC DBMS_UTILITY.COMPILE_SCHEMA (SCHEMA => ‘OLAPSYS’);
And this one: EXEC UTL_RECOMP.recomp_serial(); for all of them.
But yet I still get invalid objects ( 6 different schemas) when I run this script the SYS owner being the outstanding one.
COLUMN object_name FORMAT A10
Column owner format a10
Column object_name format a40
SELECT owner,
object_type,
object_name,
status
FROM dba_objects
WHERE status = 'INVALID'
--And owner = 'PUBLIC'
ORDER BY owner, object_type, object_name;
Any suggestions on repairing this damage short of recreating the database?
Any suggestions would help.
Regards,
al

I just did a flashback database to time. Before I did any of these procedures above. That db came up ok and you would think that everything is fine. I went in to check with the same query
COLUMN object_name FORMAT A10
Column owner format a10
Column object_name format a40
SELECT owner,
object_type,
object_name,
status
FROM dba_objects
WHERE status = 'INVALID'
--And owner = 'PUBLIC'
ORDER BY owner, object_type, object_name;
and found the same amount of objects still invalid. I know that I didn't do any work at that time because I was in a meeting. I even logged out and back in on the oem tool and sql plus and got the same invalid in the column.
Anyone knows what is going on here?

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

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

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

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.

RLBickham wrote:
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.

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.

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

    "end;";

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

Getting all Functions and Procedures using DBA_ARGUMENTS

Hi All
I am wanting to find out all functions and procedures that are within each of my packages and am using the following SQL to do this.
SELECT DISTINCT A.OBJECT_NAME, A.PACKAGE_NAME,
DECODE(POSITION,0,'FUNCTION','PROCEDURE')
FROM DBA_ARGUMENTS A
WHERE OWNER = 'NB'
I have discovered however that if a procedure has been overloaded with function will appear twice: as procedure and as a function
I was wondering if there was any workaround for this as I would only like a function to be displayed once?
Kind Regards
Mark

There is an 'OVERLOAD' column which can be used to show only specific overloads (e.g. first).
Determining which overload should be displayed in any given case may require some more thought.

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

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

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.

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.
