I'll leave it to others to comment about using other modules to write csv files so proper quoting is performed and just discuss your imediate question
This is untested, demonstration code
use strict;
use warnings;
use DBI;
my @clumps=(
{table=>'tb1',file=>"csvfile1.csv"},
{table=>'tb2',file=>"csvfile2.csv"},
{table=>'tb3',file=>"csvfile3.csv"}
);
my $dbname='a';
my $user='b';
# DBI CONNECTION
my($dbh) = DBI->connect("dbi:Ingres:$dbname","$user","")
or die "Could not connect to database $dbname\n";
for my $clump (@clumps){
my ($sth) = $dbh->prepare('SELECT * FROM '.$clump->{table})
or die "Prepare failed: $DBI::errstr\n";
$sth->execute()
or die "Prepare failed: $DBI::errstr\n";
open my $fh, ">raw", $clump->{file} or die $clump->{file}. ": $!";
$fh->print (join(",", @{$sth->{NAME}}), "\n"); #show header
while (my @row = $sth->fetchrow_array())
{
$fh->print (join(",", @row), "\n");
};
close $fh or die $clump->{file}.": $!";
$sth->finish();
}
$dbh->disconnect();
Notice how i used an array of hashes to contain the table name and outfile file, then cycled thru it to do each table/outfile file pair
Edit: Hippo was right "You've set @clumps as an arrayref but then treat as an array. Typo?"
he saw it as
my @clumps=[
{table=>'tb1',file=>"csvfile1.csv"},
{table=>'tb2',file=>"csvfile2.csv"},
{table=>'tb3',file=>"csvfile3.csv"}
];

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
