Calling a function from SQL prompt that returns a record

Hi,
I've been trying to execute a function that is present on a different database. for eg. I am loged on to a database say 'A' and trying to execute a function present in database 'B'. this function is present in a package 'X' which has 2 functions and two procedures. From the packages i am able to execute the two procedures and one of the function.
So i guess it is not a problem with the access permissions. The function that i am trying to call say function I has got 3 OUT
parameters and 1 IN parameter. the Function returns a record. When i try to execute this function i get an error. Can you please let me know as to how exactly i need to call this function from the SQL prompt...
thanx in advance

Hi Anand,
As your function has 3 OUT parameters and it returns a record you can not just call it from SQL Plus. You need to write small PL/SQL program and use variables to hold the OUT values and the returned record.
Good Luck,

Thanks in advance.If the function is performing DDL, commit or rollback inside it then you will not be able to call it from an SQL statement.
Either change the function so it doesn't perform DDL, commit or rollback, or use a different means to obtain the information you want (assuming you can't change the function)

Call external function from SQL query

Hi,
I am new to PL/SQL programming.I don't think this is possible but please let me know if there is a way to achieve this. I have a function written in VB.net and I would want to call from the query.
create table temp as select id, callvbfunction(note_text) from temp2
Here callvbfunction is the vb.net function.I need to pass note_text field value to the function.
Thanks..

Yes it is possible.
No idea how to specifically call a .Net function (from Oracle) as I do not do Windows (except for playing games ;-) ). But external procedures (extproc) and Java stored procs can be wrapped by PL/SQL wrapper functions and used in SQL statements.

Calling a function from SQL that has Out Parameters

Hello folks,
I am not sure if this is do-able, but here is my scenrio at hand. I have a database function that accepts a few IN parameters and OUT parameters. I want one of the Out parameters to display as part of my select statement. Is this possible?
Thanks

No you cannot use a function with out parameters in sql statements.
If possible make the function return that value, then use it in select.( imean instead of OUT parameter, get that OUT parameter through RETURN)

Two difficulties I can see with this.
First the application seems to allocate the array of references
internally and return a pointer to that array. In that case there must
be another function which then deallocates that array again.
Then you would need to setup the function call to have a pointer to an
int32 number for the deviceList parameter and another pointer to int32
one for the plItems parameter.
Then create another function in your DLL similar to this:
HRESULT WRAPIEnumExtractDevice(WRAPI_NDIS_DEVICE *lpDeviceList, long i,
CHAR lpszDeviceName, LONG lenDeviceName,
CHAR lpszDeviceDesc, LONG lenDeviceDesc)
if (!lpDeviceList)
return ERROR_INV_PARAMETER;
if (lpDeviceList[i].pDeviceName)
WideCharToMultiByte(CP_ACP, 0,
pDeviceList[i].pDeviceName, -1,
lpszDeviceName, lenDeviceName,
NULL, NULL);
if (lpDeviceList[i].pDeviceName)
WideCharToMultiByte(CP_ACP, 0,
pDeviceList[i].pDeviceDescription, -1,
lpszDeviceDesc, lenDeviceDesc,
NULL, NULL);
return NO_ERROR;
Pass the int32 you got from the first parameter of the previous call as
a simple int32 passed by value to this function (and make sure you don't
call this function with a higher index than (plItems - 1) returned from
the first function.

DB Adapter Calling DB Procedure that returns a Record Type

I am trying to call a PL/SQL procedure that returns a Record Type and a VARCHAR2 and I'm getting this error:
<Faulthttp://schemas.xmlsoap.org/soap/envelope/>
<faultcode>env:Server</faultcode>
<faultstring>java.sql.SQLException: ORA-06550: line 1, column 7: PLS-00306: wrong number or types of arguments in call to 'MY_PROC.GET_ID' ORA-06550: line 1, column 7: PL/SQL: Statement ignored </faultstring> </Fault>
Is there something different I need to do to handle the Record Type OUT parameter?
Thanks.

The adapter configuration wizard should take care of the Record Type for you. It should invoke JPublisher to create an equivalent Object type and a package containing a wrapper that will be called by the adapter runtime. The package also contains conversion functions for converting between your Record Type and the generated Object type. Maybe it would help if you posted the signature of your stored procedure (not the body).

Calling a BOOLEAN returning function from SQL

Hello All,
I have created below function which return BOOLEAN value :
CREATE OR REPLACE FUNCTION FUNC_1
P_EMPID IN emp.empno%type
)RETURN BOOLEAN
AS
L_VAR NUMBER;
BEGIN
SELECT 1 INTO L_VAR
FROM EMP
WHERE EMPNO = P_EMPID;
IF L_VAR = 1 THEN
RETURN TRUE;
ELSE
RETURN FALSE;
END IF;
END;Now I want to call this function from SELECT but I know that SQL does not support BOOLEAN value so I tried in other way i.e. via CASE
SELECT CASE FUNC_1(7788)
       WHEN TRUE THEN 'TRUE'
       WHEN FALSE THEN 'FALSE'
       ELSE 'NULL'
       END CASE
FROM DUALBut it is giving me error "ORA-00904: "FALSE": invalid identifier'
How can I achieve this ?
Thanks & Regards,
Rakesh

Hi Rakesh,
Why cant you try something like this, When BOOLEAN type is not supported in SQL.
Here I have made the return value a number. And, at case comparison, we get the BOOLEAN
result as TRUE of FALSE.
CREATE OR REPLACE FUNCTION func_1 (p_empid IN emp.empno%TYPE)
   RETURN NUMBER
AS
   l_var   NUMBER;
BEGIN
   SELECT count(*)
     INTO l_var
     FROM emp
    WHERE empno = p_empid;
   IF l_var = 1
   THEN
      RETURN 1;
   ELSE
      RETURN 0;
   END IF;
END;And,
SELECT CASE func_1 (55656)
          WHEN 1
             THEN 'TRUE'
          WHEN 0
             THEN 'FALSE'
       END
FROM DUAL;Which return TRUE if the Employee Number Exists and FALSE if doesnot.
Thanks,
Shankar.

Calling user function from Interface mapping

You have 2 types of calls. SQL and PL/SQL.
To call a function via SQL, it can be done using a the standard cursor interface. E.g.
select MyFunkyFunction from dualIt will return the function value via a single row with a single column. The standard cursor fetch and close cursor calls are used.
To call it via PL/SQL, an anonymous PL/SQL block is needed, and the caller needs to use a bind variable to receive the value from the function. The anon block will look as follows:
begin
:bindVar := MyFunkyFunction;
end;Refer to your client's abstract layer for interfacing with the Oracle Call Interface, on how to deal with bind variables.

}Basically you just ignore the refcursor outbound parameter.
This is a stored function, have yet to try outbound refcursor parameters in stored procedures...

No - you can NOT use DDL inside a function used in a SELECT query.
See 'Invoking Stored PL/SQL Functions from SQL Statements' in the Advanced Application Developer's Guide
http://docs.oracle.com/cd/B28359_01/appdev.111/b28424/adfns_packages.htm#ADFNS00908
The section 'Controlling Side Effects' has the information about restrictions
>
Restrictions
When a SQL statement is run, checks are made to see if it is logically embedded within the execution of an already running SQL statement. This occurs if the statement is run from a trigger or from a subprogram that was in turn invoked from the already running SQL statement. In these cases, further checks occur to determine if the new SQL statement is safe in the specific context.
The following restrictions are enforced on subprograms:
A subprogram invoked from a query or DML statement might not end the current transaction, create or rollback to a savepoint, or ALTER the system or session.
A subprogram invoked from a query (SELECT) statement or from a parallelized DML statement might not execute a DML statement or otherwise modify the database.
A subprogram invoked from a DML statement might not read or modify the particular table being modified by that DML statement.

Since DDL issues a COMMIT it would 'end the current transaction' which, as the first item above says, is not allowed.
Yes - using the AUTONOMOUS_TRANSACTION pragma can side-step that issue but that would be a serious misuse of the functionality.

How call Flash function from C++?

Communication between C++ and ActiveX Flash object is
adjusted. The ActiveX calls C++ functions. But how a call Flash
functions from C++?
I try so: v_flash is control variable of the ActiveX the
container.
A code: v_flash. CallFunction ("test");
No effect
How it to make?

Hi David, Thanks for the response. I found this solution by
following method:
Flash code either in class or frame:
ExternalInterface.addCallback("sendTextToFlash",
getTextFromJavaScript);
public function getTextFromJavaScript(user):void {
trace(user);
//Now whenever JavaScript function will be called from any
HTML or back end language then it definetly call directly that
flash function by following method
//HTML Code
function sendData(user){
//alert("values coming "+user);
SendDataToFlashMovie(user);
function getFlashMovieObject(movieName){
if (window.document[movieName]){
return window.document[movieName];
if (navigator.appName.indexOf("Microsoft Internet")==-1){
if (document.embeds && document.embeds[movieName])
return document.embeds[movieName];
else {// if (navigator.appName.indexOf("Microsoft
Internet")!=-1) {
return document.getElementById(movieName);
function SendDataToFlashMovie(user) {
var flashMovie=getFlashMovieObject("myFLA");
flashMovie.sendTextToFlash(user);
Now HTML or back end language has just need to call
sendData(
value)
I think its the right way, but if there is any other short
method like just call the function name from HTML and that directly
respond to Flash as per function name, then please let me
know.
