Function that returns all modifiable attributes

Hello,
I'm testing an application that invokes Oracle Identity Web Services. I've noticed there's a function for returning all the attributes the current user can view ('view') and also a function for determining if a given attribute can be modified by the current user ('canIModifyUserProfileAttr'). But, there doesn't seem in the dev guides I'm finding to be a function for returning all the attributes the current user can modify. It seems to be sort of expensive to invoke canIModifyUserProfileAttr for every attribute- is there a separate function or parameter I can use to wrap this payload into a single call? Thanks.

The statement READ TEXTPOOL prog INTO itab LANGUAGE lang. reads the text elements of a program in an internal table.
You can also call FM like RS_TEXTPOOL_READ (pass an explicit space value in parameter ACTION)
(You can fin many other FMs performing a where-used in FM interfaces on structure TEXTPOOL)

Error with function that returns a rowtype...

i have a function that returns a rowtype. below is a simplified version:
create or replace function "GETC"
return mytable%rowtype
is
rec mytable%rowtype;
begin
rec.rowid := 1;
return rec;
end;
eventually i'll want to call this from java. but for now i'd settle for calling it from the XE web front end (and sqlplus).
SQLPLUS: i try to call it from sqlplus by first declaring a variable where i can store the return:
var a mytable%rowtype;
it instantly stops me saying that i can only declare a var of a particular type. so what do i do?
XE interface: i tried various ways to call getc(), but they were all unsuccessful. what should i be doing?
thanks so much for your time.

Given a function like this:
CREATE OR REPLACE FUNCTION get_employee
     ( p_empno emp.empno%TYPE )
     RETURN emp%ROWTYPE
AS
     v_result emp%ROWTYPE;
BEGIN
     SELECT * INTO v_result
     FROM   emp
     WHERE empno = p_empno;
     RETURN v_result;
END get_employee;You can call it within PL/SQL like this:
DECLARE
     rec emp%ROWTYPE;
BEGIN
     rec := get_employee(7902);
     DBMS_OUTPUT.PUT_LINE(rec.ename);
END;However,
1. Unless there is a column named "ROWID" in the table (unlikely since it would conflict with the actual rowid and is therefore not allowed), the type will not have an attribute named "rowid".
2. "1" would not be a valid rowid anyway.
3. %ROWTYPE defines a PL/SQL type, which will not be recognised in other environments such as SQL and Java.

SOLVED: How can I use or call a function that returns %ROWTYPE?

Hi
edit: you can probably skip all this guff and go straight to the bottom...In the end this is probably just a question of how to use a function that returns a %rowtype. Thanks.
Currently reading Feuerstein's tome, 5th ed. I've downloaded and run the file genaa.sp, which is a code generator. Specifically, you feed it a table name and it generates code (package header and package body) that will create a cache of the specified table's contents.
So, I ran:
HR@XE> @"C:\Documents and Settings\Jason\My Documents\Work\SQL\OPP5.WEB.CODE\OPP5.WEB.CODE\genaa.sp"
749 /
Procedure created.
HR@XE> exec genaa('EMPLOYEES');which generated a nice bunch of code, viz:
create or replace package EMPLOYEES_cache is
    function onerow ( EMPLOYEE_ID_in IN HR.EMPLOYEES.EMPLOYEE_ID%TYPE) return HR.EMPLOYEES%ROWTYPE;
    function onerow_by_EMP_EMAIL_UK (EMAIL_in IN HR.EMPLOYEES.EMAIL%TYPE) return HR.EMPLOYEES%ROWTYPE;
    procedure test;
end EMPLOYEES_cache;
create or replace package body EMPLOYEES_cache is
    TYPE EMPLOYEES_aat IS TABLE OF HR.EMPLOYEES%ROWTYPE INDEX BY PLS_INTEGER;
    EMP_EMP_ID_PK_aa EMPLOYEES_aat;
    TYPE EMP_EMAIL_UK_aat IS TABLE OF HR.EMPLOYEES.EMPLOYEE_ID%TYPE INDEX BY HR.EMPLOYEES.EMAIL%TYPE;
    EMP_EMAIL_UK_aa EMP_EMAIL_UK_aat;
    function onerow ( EMPLOYEE_ID_in IN HR.EMPLOYEES.EMPLOYEE_ID%TYPE)

            return EMP_EMP_ID_PK_aa (EMPLOYEE_ID_in);
        end;
    function onerow_by_EMP_EMAIL_UK (EMAIL_in IN HR.EMPLOYEES.EMAIL%TYPE)
        return HR.EMPLOYEES%ROWTYPE is
        begin
            return EMP_EMP_ID_PK_aa (EMP_EMAIL_UK_aa (EMAIL_in));
        end;
    procedure load_arrays is
        begin

            LOOP
                EMP_EMP_ID_PK_aa(rec.EMPLOYEE_ID) := rec;

                EMP_EMAIL_UK_aa_rec := onerow_by_EMP_EMAIL_UK (rec.EMAIL);
                if rec.EMPLOYEE_ID = EMP_EMAIL_UK_aa_rec.EMPLOYEE_ID then
                    dbms_output.put_line ('EMP_EMAIL_UK lookup OK');
                else
                    dbms_output.put_line ('EMP_EMAIL_UK lookup NOT OK');
                end if;
            end loop;
        end test;
    BEGIN
        load_arrays;
    end EMPLOYEES_cache;
/which I have run successfully:
HR@XE> @"C:\Documents and Settings\Jason\My Documents\Work\SQL\EMPLOYEES_CACHE.sql"

I have figured out that the section
    BEGIN
        load_arrays;
    end EMPLOYEES_cache;
/is the initialization section, and my understanding is that this is supposed to run when any of the package variables or functions are referenced. Is that correct?
With that in mind, I'm trying to call the onerow() function, but it's not working:

Now, I have just done some googling, and it seems that what I am trying to do isn't possible. Apparently %ROWTYPE is PL/SQL, and not understood by SQL, so you can't call onerow() from sql. Correct?
So I try wrapping the call in an exec:

Of course, now that I'm looking at it again, it seems that the way to go is indicated by the first error:

So am I supposed to create a type of EMPLOYEES%ROWTYPE in a PL/SQL procedure, and the idea of this code, is that the first call to onerow() runs the initialiation code, which populates the cache, and all subsequent calls to onerow() (whether by my session or any other) will use the cache?
I've had a stab at this, but still, no joy:
create or replace procedure testcache is

Ha, figured it out

Hopefully you also figured out that the example is just that: a technical example of how to use certain Oracle functionality. Unfortunately it is also an example of what you should NOT do in an actual application.
That code isn't scaleable, uses expensive PGA memory, has no limit on the amount of memory that might be used and, contrary to your belief will result in EVERY SESSION HAVING ITS OWN CACHE of exactly the same data if the session even touches that package.
Mr. Feuerstein is an expert in SQL and PL/SQL and his books cover virtually all of the functionality available. He also does an excellent job of providing examples to illustrate how that functionality can be combined and used. But the bulk of those examples are intended solely to illustrate the 'technical' aspects of the technology. They do not necessarily reflect best practices and they often do not address performance or other issues that need to be considered when actually using those techniques in a particular application. The examples show WHAT can be done but not necessarily WHEN or even IF a given technique should be used.
It is up to the reader to learn the advantages and disadvantages of each technicalogical piece and determine when and how to use them.

That is correct. To be used by SQL you would need to create SQL types using the CREATE TYPE syntax. Currently that syntax does not support anything similar to %ROWTYPE.

NO! That is a common misconception. Each session has its own set of package variables. Any session that touches that package will cause the entire EMPLOYEES table to be queried and stored in a new associative array specifically for that session.
That duplicates the cache for each session using the package. So while there might be some marginal benefit for a single session to cache data like that the benefit usually disappears if multiple sessions are involved.
The main use case that I am aware of where such caching has benefit is during ETL processing of staged data when the processing of each record is too complex to be done in SQL and the records need to be BULK loaded and the data manipulated in a loop. Then using an associative array as a lookup table to quickly get a small amount of data can be effective. And if the ETL procedure is being processed in parallel (meaning different sessions) then for a small lookup array the additional memory use is tolerable.
Mitigating against that is the fact that:
1. Such frequently used data that you might store in the array is likely to be cached by Oracle in the buffer cache anyway
2. Newer versions of Oracle now have more than one cache
3. The SQL query needed to get the data from the table will use a bind variable that eliminates repeated hard parsing.
4. The cursor and the buffer caches ARE SHARED by multiple sessions globally.
So the short story is that there would rarely be a use case where ARRAYs like that would be preferred over accessing the data from the table.

Function that returns currently selected cell address or column

Is there a function that returns the address (or just the column) of the currently selected cell? Simply put, something like =selectedcolumn.
Background: I want to display help text in a cell, and I want that help text to change according to which cell (actually, which column) the user has selected. I have put the help texts in a hidden row. They take up too much space to be displayed all the time. I want one cell to contain the help text of the column of the currently selected cell.
Trying to not use Filemaker for this project if possible
Thanks for any help /Matt

The Numbers method, using comments as Barry showed, is probably the best method. An alternate method which is more complex would be to use an Applescript running in the background. The Applescript can scan in the background for which cell/column is currently selected and write that cell/column address into a cell in your table. A formula in your table (most likely a lookup formula) can use that address to serve up the correct help text in a diffrerent cell in the table or in another table.
Some problems with this methodare
The script is not part of the document. It is a separate entity.
The script must be started manually. It will not automatically start when the Numbers document is opened.
If the Numbers document is to be used on other Macs, each would also need the script installed.

How to define a function that returns a void?

Hi all,
How can I define a custom function that returns a void?
My understanding is simple UDF can only return a string.
Is there any way around this limitation?
Thanks.

Hi all,
Thank you all for your kind responses.
The scenario I have is I need to insert the value of a particular field into a database table. E.g. MessageId, to keep track of the messages going through XI.
Naturally, such operations return void. These operations are already encapsulated in a custom jar file.
My purpose of using a UDF is solely to invoke the operation.
But I realized I each UDF has to have a return type, and the output of this UDF must be mapped to a node in the outgoing message.
Currently, my UDF returns an empty string, by using the implementation as below, I manage to perform my desired operation without affecting the result:
MessageId -- UDF -- CONCAT -
InstitutionCD_Transformed
InstitutionCode_____
But as you can see, this is not an elegant way of doing things.
That's why I'm seeking alternative solutions for this problem.
Bhavesh, you mentioned something about doing the operation in the initialization/cleanup section.
Can you please explain more?
Thanks.
Ron

Problem with a simple function that return a number

Hi,
I'm writing a function that return a number. I receive always an error (invalid number) but I don't understand why.
The function is this:
>
FUNCTION COUNT_OBJECT(workflow_name_p IN NUMBER, object_type_p IN VARCHAR2) RETURN NUMBER
IS
object_inserted NUMBER;
BEGIN
object_inserted := 0;
IF workflow_name_p = 'AIMDailyIngestorWorkflow'
THEN
object_inserted := 1;
else
object_inserted := 100;
END IF;
RETURN object_inserted;
END COUNT_OBJECT;
I have left only an if and an assignment because I do not find the error.
When I execute the function I receive always this error:
ORA-01722: invalid number
01722. 00000 - "invalid number"
*Cause:
*Action:
There are not operation, only assignment I cannot understand.
Could someone help me?
Thanks bye bye.

I changed in this way:
FUNCTION COUNT_OBJECT(workflow_name_p IN VARCHAR2, object_type_p IN VARCHAR2) RETURN NUMBER
IS
object_present NUMBER;
object_inserted NUMBER;
table_name_p VARCHAR2(4000);
query_stmt VARCHAR2(4000);
BEGIN
IF workflow_name_p = 'AIMDailyIngestorWorkflow'
THEN
SELECT SUM(B.STOREDOBJS) INTO object_present
FROM DPCTJOBTYPESTATS B
WHERE B.WORKFLOW_NAME = workflow_name_p AND B.OBJTYPE=object_type_p;
SELECT 'AIM.'||B.TABLE_NAME INTO table_name_p
FROM DPCTSWOBJTYPE B
WHERE B.OBJTYPE=object_type_p AND SOFTWARE='AIM';
EXECUTE IMMEDIATE 'SELECT COUNT(*) FROM ' || table_name_p || ';' INTO object_inserted;
object_inserted := object_inserted - object_present;
END IF;
RETURN object_inserted;
END COUNT_OBJECT;and now the error is:
ORA-00911: invalid character
ORA-06512: at "INFRA.WORKFLOW_STATISTICS", line 504
00911. 00000 - "invalid character"
*Cause: identifiers may not start with any ASCII character other than
letters and numbers. $#_ are also allowed after the first
character. Identifiers enclosed by doublequotes may contain
any character other than a doublequote. Alternative quotes
(q'#...#') cannot use spaces, tabs, or carriage returns as
delimiters. For all other contexts, consult the SQL Language
Reference Manual.
but the line 504 is the blank line higlighted with the ***.
Why this error? The code seems correct.
Thanks, bye bye.

Function that returns N values, without using a string

Hi, how can i make a function that returns several valures (that hasn't a exact number of returned values, it could return 3 values, or 7) without using a string?
When i need to return several values from a function, i put the values inside a varchar like thus 'XXX,YYY,ZZZ' and so on. Don't know if this has a poor performance.
If you can supply simple examples for what im asking, i would be nice.
(without using a string)

Can i create the type objects inside a package? If i
can, they will be local to the package, right?Yes, you're right.
Pipeline returns a row or several?You can use pipelined function in the same way you use table:
SELECT * FROM TABLE(pipelined_funct(agr1, agr2));
It returns results as separate rows.

I get an error when i try to execute a function that returns a date value

Hi,
I'm new in ODP.NET, i'm make a package that contains a function that returns a date i.e.
Package Body General_pkg is
Function Get_Day Return Date is
vd_day date;
Begin
select sysdate into vd_day from dual;
return vd_day;
end Get_Day;
End General_pkg;
i use the next code to execute the function:
OracleCommand cmdData = new OracleCommand("General_pkg.Get_Day", cnx);
cmdData.CommandType = Commandtype.StoredProcedure;
OracleParameter PRM;
PRM = new OracleParameter();
PRM.ParameterName = "VDATE";
PRM.OracleDbType = OracleDbType.Date;
PRM.Direction = ParameterDirection.ReturnValue;
cmdData.Parameters.Add(PRM);
try
cmdData.ExecuteNonQuery();
catch(OracleException e);
When i execute this code, i have and exception, which say "identifier GENERAL_PKG.Get_Day must be declare..."
Obviously the package is correctly created in ORACLE i tested first in sql plus and it works but in ODP.NET they don't recognize the package or the function i don't know... please help!!!

OOOOOPSS.... i forgot that i change the user in my conecction string that's why it didn't work...
i guess i had to much beer last night.;. :)
thanks.

NCo 3 crashes when invoking functions that return a time field

I'm using NCo 3 (.NET 2 target framework) with Visual Studio 2010. When I invoke a function that returns time fields (like BAPI_ALM_ORDER_GET_DETAIL) NCo crashes with the following message:

Does anyone know what is the issue and how to fix it?

Is there any function that returns the latest DDL statement

can anyone tell me if there is any FUNCTION that returns latest DDL statement performed in a schema.
OR
if there is any TABLE that will be populated with latest
DDL statement in schema.
THANK YOU.

The table all_objects (and/or dba_objects) contains a column called last_ddl_time. Thus, a query like
scott@jcave > SELECT max(last_ddl_time)
2 FROM all_objects
3 WHERE owner = 'SCOTT';
MAX(LAST_DDL_TI
28-NOV-03will tell you the last time any object owned by SCOTT had DDL issued against it.

Function that returns the date/time ?

We would like to make a validation in the Activity status based on the activity End Time.
Pls... is there a function that returns something that I could compare with: "8/6/2009 01:00 PM" ?
I know of Today but I understand that today() returns just the day (no time).
Txs.
Antonio

Hi Antonio,
You can try using the function -: Timestamp()
To quote the CRM On Demand help files...
"+The Timestamp function in Expression Builder returns the server date and time converted to the current user's time zone setting. For example, if the current user's time zone setting is set to Eastern Daylight Time (EDT) -0400 UTC, the Timestamp function converts the server time to EDT. The TimeStamp function performs UTC (universal time code) conversion. NOTE: Arithmetic operations (for example, add or subtract) are not supported with the Timestamp() function.+"
Hope this helps.

Cameron

How to create a function that returns multiple rows in table

Dear all,
I want to create a funtion that returns multiple rows from the table (ex: gl_balances). I done following:
-- Create type (successfull)
Create or replace type tp_gl_balance as Object
PERIOD_NAME VARCHAR2(15),
CURRENCY_CODE VARCHAR2(15),
PERIOD_TYPE VARCHAR2(15),
PERIOD_YEAR NUMBER(15),
BEGIN_BALANCE_DR NUMBER,
BEGIN_BALANCE_CR NUMBER
-- successfull
create type tp_tbl_gl_balance as table of tp_gl_balance;
but i create a function for return some rows from gl_balances, i can't compile it
create or replace function f_gl_balance(p_period varchar2) return tp_tbl_gl_balance pipelined
as
begin
return
(select gb.period_name, gb.currency_code, gb.period_type, gb.period_year, gb.begin_balance_dr, gb.begin_balance_cr
from gl_balances gb
where gb.period_name = p_period);
end;
I also try
create or replace function f_gl_balance(p_period varchar2) return tp_tbl_gl_balance pipelined
as
begin
select gb.period_name, gb.currency_code, gb.period_type, gb.period_year, gb.begin_balance_dr, gb.begin_balance_cr
from gl_balances gb
where gb.period_name = p_period;
return;
end;
Please help me solve this function.
thanks and best reguard

Best way to write a function that returns query texts

Hi, I need to write a function that will take a parameter containing table name and based upon it returns the text of a query. Here is what I am thinking of doing it but would like to get feedback whether there is a better way to do it.
For example:
FUNCTION getSQL(p_1 VARCHAR2, p_2 VARCHAR2) RETURN VARCHAR2
IS
   sql varchar2(2000);
BEGIN
--Here i want IF THEN ELSE part and thes based upon it return a desired sql. There will be more than a dozen sqls that the function will return.
IF p_1='Employee' Then
sql:='Select * from employee Where employee_id=p_2;'
Else If p_1='Departement' Then
sql:='Select col1, col2, col3,';
sql:=sql || ' col4, col5, col6';
sql:=sql || ' Where dept_id=p_2';
Else If.....
Else If.....
Else If.....
Else If.....
End IF;
return sql;
END;Edited by: dreporter on Sep 20, 2010 8:43 AM

I'm never sure I understand the desire to put lots of cursors into a single stored procedure, given that they are inherently different things.
However, assuming you have made the above decision, you should almost certainly look at using the overload of dbms_xmlgen.newcontext that accepts a cursor parameter rather than a string. This would allow you to return cursors from your function rather than strings, giving you the option to use bind variables (and prevent associated SQL injection) and perhaps not even do dynamic SQL at all, something like this perhaps...
FUNCTION get_cursor (
   p_cursor_type VARCHAR2,
   p_cursor_parameter VARCHAR2)
   RETURN sys_refcursor
IS
   v_sys_cursor sys_refcursor;
BEGIN
   CASE p_cursor_type
      WHEN 'Employee' THEN
         OPEN v_cursor FOR
            SELECT empno, ename
              FROM emp
             WHERE empno = TO_NUMBER (p_cursor_parameter);
      WHEN 'Department' THEN
         OPEN v_cursor FOR
            SELECT deptno, dname
              FROM dept
             WHERE deptno = TO_NUMBER (p_cursor_parameter);
   END CASE;
   RETURN v_sys_cursor;
END get_cursor;
