Unidirectional mode error

[Jack19]

I need to process over a million records, to reduce the memory usage I set OracleDataset.Unidirectional=true so it won't cache that many records. I got the following error: "OracleDataset1: Record 713 not accessible in Unidirectional mode". How could I get around of that? Thanks.

In a unidirectional dataset you cannot navigate backward. If you do need previously fetched information you need to store it.
