Thread: copying tables

copying tables

From

Hi. I am trying to copy tables. I want to copy a table in one database to a
table in another database. The tables are identical. Here is to code and the
error when using DBI. Can I just use postgresQL somehow?

Thank you.

Table    = fs648

#!/usr/bin/perl -wT

use strict;
use DBI;

my $dbh = DBI->connect("dbi:Pg:dbname=misr_l1;
   host=sundog.larc.nasa.gov;port=5432", "", "")
   or die "Can't connect\n";                      #connect to database
my $sth = $dbh->prepare("SELECT * from fs648");
$sth->execute();
my $array_ref = $sth->fetchall_arrayref();
$sth->finish;
$dbh->disconnect or warn "Disconnection failed\n";
 $dbh = DBI->connect("dbi:Pg:dbname=misr_l0;
   host=sundog.larc.nasa.gov;port=5432", "", "")
   or die "Can't connect\n";                     #connect to database
foreach my $row ($array_ref)
{  my ($day, $type, $flight, $scene, $pattern, $leg, $id) = @$row;
   my $dayq = $dbh->quote($day);
   my $typeq = $dbh->quote($type);
   my $flightq = $dbh->quote($flight);
   my $sceneq = $dbh->quote($scene);
   my $legq = $dbh->quote($leg);
   my $rows = $dbh->do("INSERT INTO fs648 VALUES ( $dayq, $typeq,
      $flightq, $sceneq, $pattern, $legq, $id)");
}
$dbh->disconnect or warn "Disconnection failed\n";

DBD::Pg::db do failed: ERROR:  parser: parse error at or near "xe1154"

$pattern and $id are integers and so don't need quoting. It doesn't work if I
quote them anyway.

Thanks again!

Check out pg_dump:  basically, this works --

pg_dump -t tablename olddbname > table.out

followed by

psql -d newdbname < table.out

or

psql -d newdbname -f table.out
