ObjectDB Database Search

db tuotrial. I am just wondering, in objectdb 1.x, when i am tring to get the object id ... .toString() = 3:1 , which is not an integer and this object has two feild object id and type id ... .x to 2.x. And how can i just get the object id without type id . Thanks, Binit binitbhaskar Binit

I'm trying to fetch a list of entities, by their Id . I Use this query: SELECT c FROM User c WHERE c. id IN : ids This querey works as long as I don't set the property " id " as @ Id . If i set @ Id to any other member, this query works, if I set id as @ Id , it stops working and gives zero results

do have a UUID String as their id instead of Long which is of course causing a lot of troubles. Note ... ID , others a String UUID. Our Base-Entity everything inherits from is declared as usual with Long: @ Id @GeneratedId private Long myId; This has always been working, however, suddenly partial Objects in

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

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".

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.

Hi! I have seen a strange behavior of ObjectDB Explorer: it shows @ Id as being Long, not Integer ... used for one project.
