Using Postgresql with Grails : Missing sequence or table: hibernate_sequence

Question

I\'m having trouble with Grails 2.0 and Postgresql 9.1

I\'m trying to map an existing database, with sequential ids. However, even without creating any class in the doma

Answer 1

You can configure Postgres to use one sequence per table - I described that here: http://grails.1312388.n4.nabble.com/One-hibernate-sequence-is-used-for-all-Postgres-tables-td1351722.html

But you'll still need to create the sequence(s). dbCreate='update' doesn't create sequences (only create and create-drop do) so you'll need to manually create them or use a migration tool like http://www.grails.org/plugin/database-migration

Answer 2

You probably have one of the entities using a sequence ID generator without any sequence name configured, and Hibernate thus uses the default sequence name: hibernate_sequence, but doesn't find it.

Configure the sequence name (and use an existing sequence), or create the hibernate_sequence sequence in database, or don't use a sequence-based generator.
