Class OracleBatchCollector

java.lang.Object

de.hybris.platform.directpersistence.impl.DefaultBatchCollector

de.hybris.platform.directpersistence.impl.OracleBatchCollector

All Implemented Interfaces:

BatchCollector

public class OracleBatchCollector
extends DefaultBatchCollector

According to the Oracle documentation the result is not returned for batch updates see http://docs.oracle.com/cd/B19306_01/java.102/b14355/oraperf.htm#i1057545 "For a prepared statement batch, it is not possible to know the number of rows affected in the database by each individual statement in the batch. Therefore, all array elements have a value of -2." Using an Oracle batch there is a total returned but no result for individual statements.

This class implements a hybrid solution. Statements with optimistic locking are executed in the preprocess phase using native oracle.jdbc.OraclePreparedStatements. All other statements are executed regularly by delegating to DefaultBatchCollector.
