I use oracle9i to store information,my


My table is follows:
SQL> desc test
Name Type
------------------------------------
NEXT_VALUE NUMBER(38)


SQL> desc events;
Name Type
-------------------------------------
EVENT_ID NUMBER(19)
EVENT_DATE TIMESTAMP(6)
TITLE VARCHAR2(255 CHAR)

When I run my code,it raise following error:
Exception in thread "main" org.hibernate.id.IdentifierGenerationException: could not read a hi value - you need to populate the table: test

I guess I may create table wrong test,maybe miss some columns,but I don't know how to do it.Anybody could tell me how to do it?
Thanks

hi Friend,
when i was doing a hilo program i had got same error. for that purpose u need not to create new table if ur table is correct. i have seen ur error,
ur table creation is correct but u forgot to run commit command.
after table creation run commit cmd then ur error will solve.
