Integrating PL/SQL with Perl

Question

Hello All,
I have just started learning PL/SQL and this my first R&D stuff with PL/SQL :)
I have a very basic beginner question.
Suppose I want to insert 1 lakh rows in a table through Perl. One and easiest way to do is to prepare and execute insert queries using Perl module - 'DBI' module in a loop
But I guess this will send lot of traffic over the LAN. What I rather feel is that if I execute these 1 lakh SQL queries using PL/SQL it will be comparatively more network efficient and fast.
So I have following questions:
1. Is it possible to integrate PL/SQL with Perl using 'DBI' module
2. Is there a way in PL/SQL that it will return status of all the 1 Lakh SQL queries after execution that will let me know which SQL queries were successfully executed and which failed.

Answer 1

1. Is it possible to integrate PL/SQL with Perl using 'DBI' moduleyes, just use a PL/SQL statement instead of a sql one
2. Is there a way in PL/SQL that it will return status of all the 1 Lakh SQL queries after execution that will let me know which SQL queries were successfully executed and which failed.yes, you have to manage an exception block for each row and store the single row result in a cumulative variable:
The following code is an incomplete and not testet example:
my $STM = "
declare
ret varchar2(10);
begin
  begin
    insert into mytab values(1);
    ret := ret||'0';
  exception
    when others then
      ret:=ret||'1';
  end;
  begin
    insert into mytab values(2);
    ret := ret||'0';
  exception
    when others then
      ret:=ret||'1';
  end;
... and so on ...
  select ret into :OUTRES from dual;
end;";
my $outres;
my $hnd = $db->prepare($STM);
$hnd->bind_param_inout( ":OUTRES", \$outres, 10);  -- 10 is the variable length, e.g. the number of inserts
$hnd->execute();
print "inserts output: $outres\n";At the end of the script you should hava a string of bits. A 0 for each successful insert an 1 for each unsuccessful...
