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 +----------------------------------+----------------------------------+-------+ | Field | Type | Length| +----------------------------------+----------------------------------+-------+ | day | text | var | | type | text | var | | flight | text | var | | scene | text | var | | pattern | int4 | 4 | | leg | text | var | | id | int4 not null | 4 | +----------------------------------+----------------------------------+-------+ #!/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! Bob Kernell Research Scientist Analytical Services & Materials, Inc.
