When I write to a csv file from Perl using SQL Insert, I get either 0123 or """0123""", but I need "0123". Neither concatenation nor regex seem to resolve the issue.

Here's my code:

my $dbh = DBI->connect(qq{DBI:CSV:csv_eol=\n;csv_sep_char=\\,;});   
$dbh->{'csv_tables'}->{'Table'} = {'file' => 'data.csv','col_names' =>
+ 
["num","id"]};
#Setup error variables
$dbh->{'RaiseError'} = 1;
$@ = '';

## Attempts to change $num
##$num = '"'.$num.'"';## this causes """0123""" 
##$num = "\"$num\"";## this causes """0123""" even if I additionally d
+o this: 
## $num=~s/"""/"/g;
##$num = " ".$num;## causes " 0123" VERY CLOSE.  Try next line: 
##$num=~s/ //g;## This causes 0123
##$num = "".$num; ## causes 0123
##$num = "'".$num."'";## causes 123

my $value = "\'$num\',\'$id\'";
my $insert = "INSERT INTO Table VALUES ($value)";
my $sth = $dbh->prepare($insert);
$sth->execute();
$sth->finish();
$dbh->disconnect();

I would like to have the output of $num to end up being "0123" in the CSV, but instead I get 0123 or """0123""" or " 0123"

Any suggestions?
