When I create a table via liquibase I have to use int type. And cannot use long cause it’s not supported:

1. &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 
2. &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 
3. &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 

Which type should I use when I define an entity? Should it be long or int or something else?

1. @Id
2. &nbsp; &nbsp; private long id;

I’d like to have the same scheme generation script when I invoke liquibase:updateSQL or generate it via hibernate option. But it is not clear to me the mapping issue.

If I want to use long as type in Java code, I have to use bigint as type in the liquibase. So, the issue is resolved.
