Hi Matt,

Thanks for this. Yes DBD::mysql makes some attributes available, 
including mysql_errno and mysql_error. I believe these are propagated up 
through DBI and Class::DBI. But the detailed information, which users 
want and which my attempt at automatic recovery needs, is buried in the 
MySQL mysql_error string, AFAIK. So it seems like I need to parse that 
and I can't believe I'm the first to want to do it :)

Cheers, Dave
