DBIx::DataModel::Statement::Oracle - Statement for interacting with DBD::Oracle
DBIx::DataModel->Schema("MySchema", statement_class => "DBIx::DataModel::Statement::Oracle", ); my $statement = $source->select( ..., -limit => 50, -offset => 200, -result_as => 'statement, ); my $total_rows = $statement->row_count; my $row_slice = $statement->all;
This is interesting for applications that need to do pagination within result sets, because Oracle has no support for LIMIT/OFFSET in SQL. So here we use some special methods of the Oracle driver to retrieve the total number of rows in a resultset, or to extract a given slice of rows.
The API is exactly the same as other, regular DBIx::DataModel implementations.
