How to insert and fetch java.time types such as LocalDate via JDBC to an SQL database such as the H2 Database Engine ? The old way using PreparedStatement::setDate and ResultSet::getDate works for the legacy java.sql.Date type. I want to avoid using these troublesome old date-time classes. What is the modern way for sending java.time types through a JDBC driver ? We have two routes to exchanging java.time objects through JDBC: JDBC 4.2 compliant drivers If your JDBC driver complies with the JDBC 4.2 specification or later, you can deal directly with the java.time objects. Older drivers, before

At the moment we use HSQLDB as an embedded database, but we search for a database with less memory footprint as the data volume grows. Derby / JavaDB is not an option at the moment because it stores properties globally in the system properties. So we thought of h2 . While we used HSQLDB we created a Server-object, set the parameters and started it. This is described here (and given as example in the class org.hsqldb.test.TestBase). The question is: Can this be done analogous with the h2 database, too? Do you have any code samples for that? Scanning the h2-page, I did not find an example. From

I'm trying to make a chart in my application that returns me the temperature of days during the months. This chart is a JFreechart TimeSeriesCollection, and I am unable to have the graph read correct data from the database.
