When using rows to limit SQL we get the warning: Show quoted text
> DBIx::Class::SQLMaker::select(): Support for the legacy emulate_limit() > mechanism inherited from SQL::Abstract::Limit has been deprecated, and > will be removed when DBIC transitions to Data::Query. If your code uses > this type of limit specification please file an RT and provide the source > of your emulate_limit() implementation, so an acceptable upgrade-path can > be devised
Genesis SQL's dialect uses SELECT TOP n sub emulate_limit { my ($self, $sql, $rs_attrs, $rows, $offset) = @_; $sql =~ s/^ \s* SELECT \s+ //ix or $self->throw_exception("Unrecognizable SELECT: $sql"); return sprintf ('SELECT %s%s%s%s', $offset ? sprintf('SKIP %u ', $offset) : '' , sprintf('TOP %u ', $rows) , $sql, $self->_parse_rs_attrs ($rs_attrs), ); }
