=head1 NAME
DBIx::Class::Storage::DBI::Oracle - Automatic primary key class for Oracle
=head1 SYNOPSIS
# In your table classes
__PACKAGE__->load_components(qw/PK::Auto Core/);
__PACKAGE__->set_primary_key('id');
__PACKAGE__->sequence('mysequence');
=head1 DESCRIPTION
This class implements autoincrements for Oracle.

=head2 get_autoinc_seq
Returns the sequence name for an autoincrement column
=cut

my ($self, $source, $col) = @_;
$self->dbh_do($self->can('_dbh_get_autoinc_seq'), $source, $col);
}
=head2 columns_info_for
This wraps the superclass version of this method to force table
names to uppercase
=cut
sub columns_info_for {
my ($self, $table) = @_;
$self->next::method(uc($table));
}
=head2 datetime_parser_type
This sets the proper DateTime::Format module for use with
L<DBIx::Class::InflateColumn::DateTime>.
=cut
