com.feedzai.commons.sql.abstraction.dml.result.DB2ResultColumn

All Implemented Interfaces:

Serializable

public class DB2ResultColumn
extends ResultColumn

ATTENTION: Blob columns must be processed at instantiation because the engine closes the result set and the data won't be accessible hence the processObject(Object) implementation.

Since:

2.0.0
