Hi,

I'm using PB2022, build 1900 with Oracle 19 database.

My question has to do with overloading and calling functions in a Oracle package. In native PB (Desktop) all works fine but with PowerServer there are issues.

Here is my test case. The package is TEST and it has two funtions

FUNCTION F_get_lucky
  RETURN  number IS
begin
    RETURN 777;

END;

FUNCTION F_get_lucky(p_number in number)  
  RETURN  number IS
begin
    RETURN p_number;
END;


In the application SQLCA these are defined as 

function long f_get_lucky() RPCFUNC ALIAS FOR "test.f_get_lucky"
function long f_get_lucky(Long LuckyNumber ) RPCFUNC ALIAS FOR "test.f_get_lucky"


When calling the function from the app using e.g. 

MessageBox("f_get_lucky", sqlca.f_get_lucky())

This the error message I get in the PowerServer console window.

"ErrorMessage": "ORA-06550: line 1, column 7:\nPLS-00306: wrong number or types of arguments in call to 'F_GET_LUCKY'\nORA-06550: line 1, column 7:\nPL/SQL: Statement ignored"

When calling a non-overloaded version of the function, all works fine.

Is it so that PowerServer doesn't not suport this type of overloading or should I do things differently?

Thanks,
Kari
