ObjectDB Database Search

Hi,  I have noticed some values of id column suddenly switched to int ... / To repair IDs that have already changed their types you will have to 'touch' the objects and store them again, or use an ObjectDB version before the fix, with an UPDATE queries that change the IDs

Hi, I have a question about populating auto generated id before transaction commit. We are using ... transaction is committed so all returned entities are not populated with ID in this context. How can I force ODB to populate entity ID before transaction is committed? Or maybe there is another way

could I change sequcence id ? allocating small value may not be effect. or something other ways ... MyEntity is defined with JPA @Entity public class MyEntity {     @ Id     @GeneratedValue(strategy=GenerationType.IDENTITY)     private Long id ; }   Tsu

= GenerationType.SEQUENCE, generator = "sampleSeqGenerator") @ Id long id ;   The id field is as expected ... etc. that makes use of the id . How do I capture that id without roundtripping? I see pre and post commit, but pre the id isn't generated yet, and post I would have to somehow resave. mbcladwell

is id =0. What situation will be id =0? TIA gzdillon Lai Yang This happens if you define an id field ... ; @GeneratedValue should solve the problem, unless you already have entity objects with IDs 0 ... table - you can set an initial ID which is larger than any existing ID to avoid any conflict. support Support

Sample world DB in ObjectDB Explorer - and couldn't find my country, as it has invalid id ( ez instead of cz ). I changed the id of country to "cz". But when I try to find the country: SELECT c FROM Country c WHERE id = "cz" no results are returned. If i find it by name, I can see ID has changed to cz

Make sure you set ... (name = "XXX", sequenceName = "Seq_XXX", initialValue = 1000) @GeneratedValue(generator = "XXX") @ Id

I have an entity with 2 @ ID @Entity public class TheTable extends AbstractMMODataObject { @ Id String userId; @ Id long range; It was a mistake, I really should have just made  range an @Index but it already has millions of records in it. I am wondering if I query select t from  TheTable t where range

Hi! I have seen a strange behavior of ObjectDB Explorer: it shows @ Id as being Long, not Integer ... used for one project. If I open one of the entities in the explorer, then I click on it's id (in the sample on parts of the Embedded id ) as if I would want to edit, then I press enter and ObjectDB

First all, congratulations to Objectdb team for the excellent work. Possible issue for default id generator when strategy is sequence. Error: Incomplete definition of auto value in field MyTestCase ... and 36: @GeneratedValue(strategy=GenerationType.SEQUENCE)//, generator="seq") @ Id @SequenceGenerator

Category but they are all refering to same limited set of Category entities (via ID ). There is not changes made to Category from Product. The category ID is taken from the webservice Object ID (unique too). @Entity public class Product implements Serializable { @ Id @GeneratedValue private long id
