Method Details

supportsBulkInsertionIdentifierGeneration

default boolean supportsBulkInsertionIdentifierGeneration()

Given the configuration of this generator, is identifier generation as part of bulk insertion supported?

Returns:

true if bulk insertions are supported; false otherwise.

API Note:

Mainly here to allow stuff like SequenceStyleGenerator which can support this based on configuration

determineBulkInsertionIdentifierGenerationSelectFragment

default String determineBulkInsertionIdentifierGenerationSelectFragment(SqlStringGenerationContext context)

Return the select expression fragment, if any, that generates the identifier values.

Returns:

The identifier value generation fragment (SQL). null indicates that no fragment is needed.
