Subject: Replace the fallback _dbh_last_insert_id with an explicit exception.
X-Git-Tag: v0.08100~48
X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?a=commitdiff_plain;h=93b7182b41791a8253cef12f02805eaab05df91d;p=dbsrgits%2FDBIx-Class.git

Replace the fallback _dbh_last_insert_id with an explicit exception.
Currently all known Storage::DBI engines provide their own _dbh_last_insert_id, except for Storage::DBI::Sybase, for which the old sqlite-ish fallback doesn't work anyway: http://rt.cpan.org/Public/Bug/Display.html?id=40265
