I am new to perl asking for Compassion from the monks. Assume that I have an array of tables and that one db has all the data in it and another db just has structure in it. One db is ingres, the other db is mysql. The tables are the same on both. Is there a loop or other easy way using dbi to copy the tables over, or do I need to write a loop for each table to create the insert queries to write over.
ex
 
### Table 1
    $sth = $dbh->prepare("select * from master_table_1");

while (@row=$sth->fetchrow) {
$query = "insert into back_table_2 (f1,f2,f3) VALUES ('@row[0]','@row[
+1]','@row[2]')"

}

### Table 2
### Table 1
    $sth = $dbh->prepare("select * from master_table_2");

while (@row=$sth->fetchrow) {
$query = "insert into back_table_2 (abc1,abc2,abc3) VALUES ('@row[0]',
+'@row[1]','@row[2]')"

}

Does this make sense, is there any easy way to do this? Please excuse my lack of english.
I was hoping to do this with loops and not modules.
