I have a set of JPA entities that have their IDs generated by a sequence:
@GenericGenerator(
name = "catalog_items_history_seq",
strategy = "org.hibernate.id.enhanced.SequenceStyleGenerator",
parameters = [
(Parameter(name = "sequence_name", value = "catalog_item_history_sequence")),
(Parameter(name = "initial_value", value = "1")),
(Parameter(name = "increment_size", value = "1"))
]
)
class CatalogItemHistory {
@Id
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "catalog_items_history_seq")
var id: Long = -1
}
When I run the diffChangeLog gradle task the first time, i get the proper CREATE SEQUENCE statements and the sequences are created ok.
However, if i run the task again, my changelog contains changes like this:
<changeSet author="raibaz (generated)" id="1582110272824-1">
<alterSequence sequenceName="catalog_item_history_sequence"/>
</changeSet>
Which result in a syntax error, because the SQL they produce is ALTER SEQUENCE catalog_item_history_sequence which is invalid as it's not actually altering anything.
When i run liquibase to update my database schema, then, what i get is:
Caused by: liquibase.exception.DatabaseException: ERROR: syntax error at end of input
Posizione: 52 [Failed SQL: (0) ALTER SEQUENCE public.catalog_item_history_sequence]
My database is PostgreSQL 12.
What am I missing? Is there a way to prevent liquibase from creating these changes?
