OK,

Thanks for the replies, I Have delved even deeper into this, and it turns out that to get this working the way I want to, I have to call a oracle stored procedure and get it to return a Oracle cursor.

Therefore part of my code in the main program now looks like this.

 my $accessroles;                                
   
   $accessroles = $dbh_conn->run_query('check_user', "begin Mrf_Maint.
+check_user(?,?); end;", $login_id, $accessroles );
  
    while(my $hashRef = $accessroles->fetchrow_hashref()){
      foreach(keys %$hashRef){
         print "$_ is $hashRef->{$_}<br>";
      }
   }

and in my database module, the run_query code looks like this

my $self = shift;
   my $name = shift;
   my $query = shift; 
   my $login_id = shift; 
   my $accessroles = shift;  
   
   my $ora = "ORA_RSET";  
   
   my $sth = $self->{'_conn'}->prepare($query) || print $DBI::errstr; 
   
   $sth->bind_param(1, $login_id);          
   $sth->bind_param_inout(2, \$accessroles, 0, { ora_type => 'ORA_RSET
+'} );    
   
   $sth->execute() || print $DBI::errstr;
   
   return $accessroles;

The second parameter that I'm binding is the OUT parameter as well as being of type CURSOR, which is why it also needs a few more parameters in the bind_param_inout call (line 52 in module).

However The error message I now recieve is
Can't bind :p2, ora_type 0 not supported by DBD::Oracle at Database.pm line 52.
Any further suggestions would be great.

PS, pl/sql code looks like this

CREATE OR REPLACE PACKAGE Mrf_Maint AS
   TYPE mrf_role IS REF CURSOR; 
    
    PROCEDURE check_user(mrfid       IN  VARCHAR,                     
+    mrfrole     OUT Mrf_Maint.mrf_role);

END Mrf_Maint;

and body

CREATE OR REPLACE PACKAGE BODY Mrf_Maint
IS

PROCEDURE check_user(mrfid      VARCHAR,
                    mrfrole     OUT Mrf_Maint.mrf_role)  
IS

     crsr Mrf_Maint.mrf_role;   

BEGIN

     OPEN crsr FOR SELECT access_role FROM TABLE WHERE field = mrfid;
END;



END;
