Method Detail

sqlCreateStrings

String[] sqlCreateStrings(Dialect dialect)
                          throws HibernateException

The SQL required to create the underlying database objects.

Parameters:

dialect - The dialect against which to generate the create command(s)

Returns:

The create command(s)

Throws:

HibernateException - problem creating the create command(s)

sqlDropStrings

String[] sqlDropStrings(Dialect dialect)
                        throws HibernateException

The SQL required to remove the underlying database objects.

Parameters:

dialect - The dialect against which to generate the drop command(s)

Returns:

The drop command(s)

Throws:

HibernateException - problem creating the drop command(s)

generatorKey

Object generatorKey()

Return a key unique to the underlying database objects. Prevents us from trying to create/remove them multiple times.

Returns:

Object an identifying key for this generator
