Class PersistentTableMutationStrategy

java.lang.Object

org.hibernate.query.sqm.mutation.internal.temptable.PersistentTableStrategy

org.hibernate.query.sqm.mutation.internal.temptable.PersistentTableMutationStrategy

All Implemented Interfaces:

SqmMultiTableMutationStrategy

public class PersistentTableMutationStrategy
extends PersistentTableStrategy
implements SqmMultiTableMutationStrategy

This is a strategy that mimics temporary tables for databases which do not support temporary tables. It follows a pattern similar to the ANSI SQL definition of global temporary table using a "session id" column to segment rows from the various sessions.
