Re^2: Catching DBI (or other) errors

[duckyd]

If I were going to do something like this, I'd probably do something more like:

$query->execute and $sql_stage++;
$query2->execute and $sql_stage++;

etc.

[Crackers2]

That would execute all queries even if one of them failed though. And if after your code finishes, $sql_stage is 1, you still don't know whether it was $query or $query2 that failed. Now add 3 or 4 more queries to that list and the $sql_stage variable becomes practically useless for anything except comparing to the total number of queries.

But wrapped in an eval and combined with RaiseError, it would stop counting at the point where your query goes wrong.

It is a bit annoying in that you have to count your queries to know which went wrong, but there may be one or two specific action points: if queries 1-4 succeeded, but 5-8 failed do X, otherwise do Y.
