in reply to Deleting all from all tables in MYSQL


You can't use placeholders that way. MySQL can't parse a statement like "delete from ?", so you can't prepare it. You are pretty much stuck with "delete from $row[0]".

    Thanks. So would this work instead?
    my $query = $dbh->prepare('SHOW TABLES'); if (defined($query)) { $query->execute(); my @row; while (@row = $query->fetchrow_array()) { $sql = qq|delete from $row[0]|; $sth = $dbh->prepare($sql) or die "Cannot prepare: " . $dbh->errstr(); $sth->execute() or die "" . $sth->errstr();

[marto]: hmm, may have to patch CPAN::Meta to move from search.cpan to metacpan in the META.json/yml files
[Corion]: marto: Heh - it seems that they plan to keep the links alive for a long time. But still, I plan on moving PM to use/generate the new links
[Corion]: And I think it's better to generate links to the new world instead of keeping the older links alive by generating new versions of them ;)
[marto]: yeah, I guess it's supposed to be a permanent redirect, but better to make the move where possible
