Hi you almost got it is very simple but since english is my
second or third language is getting hard, look you almost
got it, I want to do this, from a MYSQL table call
PATENTES get ONLY the field PAT, to do this I have
to do this :

  my $dbh = DBI->connect("DBI:mysql:database=proyecto;host=localhost",
                         "root", "xyz123",
                         {'RaiseError' => 1});
   my $sth = $dbh->prepare("SELECT PAT FROM patentes");

 $sth->execute();
   while ((my @row) = $sth->fetchrow_array()) {
   print "@row->[0]\n";
   }
[download]

so far so good, at this point I have @row->[0] that has all the data from the field PAT of the table PATENTES.

Now with these array I want to use it in another file this is a CSV datafile and it has a PAT field too, so I want to extract the data from this file using PAT and if posible to create a new CSV file with the name of the field PAT using INTO OUTFILE, I try to do this but did not work:

my $dbh = DBI->connect("DBI:mysql:database=proyecto;host=localhost",
                         "root", "xyz123",
                         {'RaiseError' => 1});
   my $sth = $dbh->prepare("SELECT PAT FROM patentes");

  $sth->execute();
   while ((my @row) = $sth->fetchrow_array()) {

my $dbh = DBI->connect('dbi:AnyData(RaiseError=>1):');
  $dbh->func( 'cars', 'CSV', 'testperl.csv', 'ad_catalog');
  my $sth = $dbh->prepare("SELECT * INTO OUTFILE @row->[0].csv FROM ca
+rs WHERE pat = @row->[0]);
  $sth->execute();

}

Hope this is more exact
