DBIx::DataModel::Statement::Oracle - Statement for interacting with DBD::Oracle
DBIx::DataModel->Schema("MySchema", statement_class => "DBIx::DataModel::Statement::Oracle", ); my $rows = $source->select( ..., -limit => 50, -offset => 200, );
This subclass redefines some parent methods from DBIx::DataModel::Statement in order to take advantage of "Scrollable Cursor Methods" in DBD::Oracle.
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 jump to a specific row within a resultset, and then extract a limited number of rows.
The API is exactly the same as other, regular DBIx::DataModel implementations.
