So these are just some fields like column1 and column2 - nothing
to do with duration of the process itself.
The following is in php and uses class db_mysql - there are
numerous other ways to do it, just to show you how I would do it:
$db = newDB($db);
//connect to database
$q = "SELECT * FROM table 1
WHERE key1 = 'value1'";
//state query, try insert
$db->query($q);
//perform query
if ($db->nf()){//success
$db->next_record();//get record
$field1 = $db->f('field1');//extract field
}
//now look at the other table
$q = "INSERT INTO table2
(col1, col2, col3) //and so on
VALUES ('$field1', '$field2', '$field3')";
//state query
$db->query($q);
//perform query
if ($db->Errno){//entry already there
$q = "UPDATE table2
SET val1 = '$field1',
val2 = '$field2',
val3 = '$field3',
WHERE key2 = '$field1'";//assuming that this is a key element
//do an update instead
$db->query($q);
}

Personally, I prefer php to perl, but it is a matter of taste and
experience. There is an entertaining article entitled MySQL Wizardry
at address
http://mysql.com/articles/wizard/
which shows how to work with databases and perl. Highly
recommended.
