SqlObject is a declarative, annotation-driven API for database access. It complements the core API. Jdbi 3 is designed to provide convenient tabular data access in Java(tm) and other JVM based languages. It uses the Java collections framework for query results, provides a convenient means of externalizing SQL statements, and named parameter support for any database that supports JDBC.

There is a newer version: 3.47.0
