Deprecated

since 6.2.

because both Source and hbm.xml are deprecated, though this implementation is instructive

Value generation strategy using the query Dialect#getCurrentTimestampSelectString(). This is a select that occurs before the insert or update, whereas with CurrentTimestampGeneration the select happens afterward.

Underlies the @Source annotation, and <timestamp source="db"/> in hbm.xml mapping documents.
