I've got some simple procedure which returns record(s):

CREATE OR REPLACE PROCEDURE "GET_SYS_DATE"
(
RESULTSET IN OUT SYS_REFCURSOR
)
IS

BEGIN
OPEN RESULTSET FOR
SELECT SYSDATE FROM DUAL;
END;

In perl i invoke it with somthing like this:

my $ret;

my $s= "BEGIN GET_SYS_DATE(:1); END;";
my $sth = $dbh->prepare($s);
$sth->bind_param_inout(1, \$ret, 0 { TYPE => XXX}); # tried to use many DBD::SQL_* types (SQL_ROW, SQL_REF, etc.)
$sth->execute(); #... but without luck

I always get:
DBD::ODBC::st execute failed: [Oracle][ODBC][Ora]ORA-06550: line 1, column 7:
PLS-00306: wrong number or types of arguments in call to 'GET_SYS_DATE'
ORA-06550: line 1, column 7:
PL/SQL: Statement ignored

Of course if i use other datatype in SP (e.g. VARCHAR2) and bind it as SQL_VARCHAR it works well... Moreover, if i use DBD::Oracle and bind it as ORA_RSET type it also works.

Is it possible that ODBC doesn't know SYS_REFCURSOR type? Then, is there any way to call SP and retrieve cursor from perl without using DBD::Oracle?

Or, if it is possible, then how to retrieve that cursor and data stored within it? Any help?
