Method Detail

load

DataObject load(java.sql.ResultSet rsQueryResults,
                int initialIndex)
                throws OSSDatabaseAccessException

Load full DataObject from the result set. It is used when all attributes of the data objects should be loaded as efficiently as possible. Every data has to be loaded otherwise we couldn't test the existence data therefore this method is commong to all the database factories

Parameters:

rsQueryResults - - ResultSet retrieved from the database

initialIndex - - initial column index in the result set to retrieve, by default this is 1. This allows to include columns for this database factory mixed with columns for other database factories and the load them efficiently.

Returns:

DataObject - with specific columns set

Throws:

OSSDatabaseAccessException - - error during ResultSet parsing
