To test if rollback is supported, set $dbh->{AutoCommit} to 0, then read it again; if it's still 0, then you have transactions.

You should have the entire transaction - from when you turned autocommit off / issued a START TRANSACTION command (ok, $dbi->begin_work() :-)) to where you call $dbi->commit() - inside one big eval(), and replay the block if it fails, say, up to three times - to help it stumble along in the case of high concurrency / locking issues.

This might be RDBMS dependant, but you don't have to issue a ->rollback() if the commit() failed; that is implicit. ->rollback() is for when you change your mind about the query halfway through. 

$h=$ENV{HOME};my@q=split/\n\n/,`cat $h/.quotes`;$s="$h/."
."signature";$t=`cat $s`;print$t,"\n",$q[rand($#q)],"\n";
