justin423 has asked for the wisdom of the Perl Monks concerning the following question:
Can somebody tell me where I am going wrong with this code?
I am trying to delete all the data from every table in the database by importing the data coming from show tables into a query that deletes all the data.
(there is probably another way, using the informa_schema, I'll try that if nobody can answer this one)
Thanks
my $query = $dbh->prepare('SHOW TABLES'); if (defined($query)) { $query->execute(); my @row; while (@row = $query->fetchrow_array()) { $sql = qq|delete from ?|; $sth = $dbh->prepare($sql) or die "Cannot prepare: " . $db +h->errstr(); $sth->execute($row[0]) or die "Cannot execute: " . $sth->e +rrstr(); } } $query->finish();
