jDBI provides a convenience interface for SQL operations in Java. It is not intended as an abstraction layer, but rather a library which makes the common things easy and the hard things possible, to paraphrase Larry Wall. The primary entry point for using jDBI is the DBI class. This is used to create Handle instances, each of which represents a connection to the RDBMS. A Handle wraps a JDBC Connection instance, and makes use of that same Connection for all of its operations. Generally, you will explicitely create statements, queries, and batch operations for working with data in the database. Seperate objects are used to represent these things, and they are designed to be used in a somewhat literate-programming style. Here is an example: DBI dbi = new DBI("jdbc:derby:testing"); Handle handle = dbi.open(); Query<Something> query = handle.createQuery("select * from something where name like :name") .bind("name", "Eri%") .map(Something.class); List<Something> rs = query.list(); handle.close(); INSTALLATION Building requires Apache Ant ( http://ant.apache.org/ ) If ant complains that it cannot find the JUnit task, copy the junit-3.8.1.jar into the $ANT_HOME/lib directory, or into $HOME/.ant/lib and try again. To build the runtime library, use "ant jar" This will produce a jdbi-<version>.jar in the build/ directory There are no library dependencies for jDBI To run the unit/regression test suite use "ant test" Test report will be in the report/ directory The test suite requires the libraries in the lib/test/ directory and uses the Apache Derby ( http://www.apache.org/ ) embedded database for its tests.
