Hey Chuck,
We replicate data on a regular basis from Oracle to MySQL and back using
perl cron scripts. Here's a basic one for ya:
#!/usr/bin/perl
use strict;
use DBI;
my $dbh1=DBI->connect("DBI:mysql:dbname:host.mark.com:6969", 'root'
,'password');
my $dbh2=DBI->connect("DBI:mysql:dbname2:host2.mark.com:6969", 'root'
,'password');
my $sth1 = $dbh1->prepare("select name, sex from members");
my $time = time();
my $sth2 = $dbh2->prepare("insert into members (name, sex, stamp) values (?,
?, $time)");
$sth1->execute();
my ($name, $sex);
while(($name, $sex) = $sth1->fetchrow())
{
print "inserting $name\t$sex\n";
$sth2->execute($name, $sex);
}
$sth1->finish();
$sth2->finish();
$dbh1->disconnect();
$dbh2->disconnect();
exit;
--cut--
I probably forgot something really silly because I haven't tested this at
all but I think that'll get ya started. You'll need perl5 with DBI
installed. Once you install DBI do a
perldoc DBI
and that will give you tons of info. Perl is definitelly the way to go if
you're sucking data from one DB, parsing and inserting into another.
Mark.

Thanks for replying.
I know the SQL commands, I want to know how to automate the whole sequence.
I've always written php pages that do the calls. I want to write a script
to do it on the server as a cron job or something.
thanks
Chuck
