It seems that the ‘long’ data type has disappeared. If I try to create an entity (in an ER diagram), I cannot define a key as ‘long’. I basically want to create a key ‘id’ with a increment ID Generator.
My choice is a ‘bigint’ which does not work because hibernate throws a “org.hibernate.id.IdentifierGenerationException: this id generator generates long, integer, short or string” when trying to persist this object. I do not want to use a standard integer because I need a long to support millions of records.
What is the logic behing removing the ‘long’ data type?
The reason why there is no “long” in the db column is because “long” is not a valid type in MySQL (see http://dev.mysql.com/doc/refman/5.0/en/numeric-types.html ). We have tested using “bigint” in ID column and mapped to “long” in class attribute which working fine with incremental id generator. May I know what type you mapped for “bigint” in class model?
