Method Detail

supportsBulkInsertionIdentifierGeneration

boolean supportsBulkInsertionIdentifierGeneration()

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

IMPL NOTE : Mainly here to allow stuff like SequenceStyleGenerator which *can* support this based on configuration

Returns:

true if bulk insertions are supported; false otherwise.

determineBulkInsertionIdentifierGenerationSelectFragment

String determineBulkInsertionIdentifierGenerationSelectFragment(Dialect dialect)

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

Parameters:

dialect - The dialect against which the insert will be performed.

Returns:

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