It should be transparent to the user. =cut sub _rebless { shift->_determine_connector_driver('ADO') } # cleanup some warnings from DBD::ADO # RT#65563, not fixed as of DBD::ADO v2.98 sub _dbh_get_info { my $self = shift; local $SIG{__WARN__} = sigwarn_silencer( qr{^Missing argument in sprintf at \S+/ADO/GetInfo\.pm} ); $self->next::method(@_); } # Monkeypatch out the horrible warnings during global destruction. # A patch to DBD::ADO has been submitted as well, and it was fixed # as of 2.99 # https://rt.cpan.org/Ticket/Display.html?id=65563 sub _init { unless ($DBD::ADO::__DBIC_MONKEYPATCH_CHECKED__) { require DBD::ADO; unless (try { DBD::ADO->VERSION('2.99'); 1 }) { no warnings 'redefine'; my $disconnect = *DBD::ADO::db::disconnect{CODE}; *DBD::ADO::db::disconnect = subname 'DBD::ADO::db::disconnect' => sub { local $SIG{__WARN__} = sigwarn_silencer( qr/Not a Win32::OLE object|uninitialized value/ ); $disconnect->(@_); }; } $DBD::ADO::__DBIC_MONKEYPATCH_CHECKED__ = 1; } } # Here I was just experimenting with ADO cursor types, left in as a comment in # case you want to as well.
