Most DBDs won't allow placeholders for a table name. Try using variable interpolation. For example ;
#!/usr/bin/perl
use strict;
use DBI;
my $db_table = 'test1';
my $dbh = dbh();# connect code as required
#my $count = $dbh->do("DELETE FROM $db_table");
#print "$count lines deleted from $db_table\n";
my $sql = <<SQL;
LOAD DATA LOCAL INFILE ?
INTO TABLE $db_table
FIELDS TERMINATED BY ','
LINES TERMINATED BY '\n'
(field1, field2, field3);
SQL
my $count = $dbh->do($sql,undef,'importfile.csv');
print "$count lines inserted into $db_table\n";
my $sql = qq{ SELECT * FROM $db_table };
my $sth = $dbh->prepare($sql);
$sth->execute();
while (my @f = $sth->fetchrow_array){
print "@f\n";
}
