in reply to Perl DBI + Access bind issues

From the DBI pod:

The "do()" method can be used for non repeated non-"SELECT" statement (or with drivers that don't support placeholders):
$rows_affected = $dbh->do("UPDATE your_table SET foo = foo + 1");

As a pragmatic solution, I'd go with $dbh->do() rather than $sth = $dbh->prepare(); $sth->execute() to avoid having to write a patch ;-)

...but then, input sanitizing would rest heavily on my own shoulders...

update - uhm, scratch that, note the 'non-"SELECT" statement' above :-(

update 2: thinking about it again - the best solution is to grab a LART and make that user rename the columns.

[Corion]: ambrus: Hmmm. It makes sense that AnyEvent would implement the push_write itself, but I think I don't have a good idea of where the boundary between AnyEvent and the underlying event system lies... Implementing the timer should give me a better idea
[ambrus]: Corion: push_write is in the higher level abstraction of AnyEvent::Handle, not in the watcher
[Corion]: ambrus: Hmm - rereading Prima::File, that merrily coincides with what Prima does - it tells you "you can read", and you're supposed to read from the fh yourself. I thought it called you with the data already read, which would've been harder to integrate
[ambrus]: you just need an io watcher, created by &AnyEvent::Impl:: Whatever::io(...)
[Corion]: So after talking it through with you even while I'm still not entirely clear on where AE ends and my implementation begins, I think I understand that I only need to implement some smaller parts for each functionality I want to support.
[Corion]: Yeah... and you might even be able to mix and match additional functionality if you have additional async suppliers, like from a separate thread
[ambrus]: You hvae to be careful with the timer, because apparently Prima::Timer insists on being periodic, wheras AnyEvent::Impl:: Whatever::timer should give a one-shot timer watcher
