I want to write Java code to work with a database, no matter which database is used. My problem is that it wouldn’t be Object related. There are some insertions and queries that are but most of them aren’t.
Right now we are using Postgresql and pure JDBC, but we may have to make it work with Oracle.
Can Hibernate (which I’ve never used) solve my problem or should I go for something else ?
I have created jOOQ precisely for that. jOOQ models SQL itself as a domain-specific language in Java. It embraces using standard and vendor-specific features, such as built-in functions, window functions, stored procedures, hierarchical queries, etc. Whenever possible, a vendor-specific functionality from one database is simulated for other databases. That way, most of jOOQ-generated SQL is compatible with any of its 13 supported databases.
