JDBC

The low-level API for connecting to relational databases.

Easy

try (var con = DriverManager.getConnection(url, user, pass);
     var ps = con.prepareStatement("select * from readings where sensor = ?")) {
    ps.setString(1, "t1");
    try (var rs = ps.executeQuery()) { while (rs.next()) … }
}

Always use PreparedStatement to prevent SQL injection.
