- Overview Every DuckDB feature reachable from Java starts with a Connection . This page covers the JDBC URL forms the driver accepts, how DuckDB and driver options are passed and which of them win, how connections come to share (or not share

Opening a Connection In JDBC, database connections are created through the standard java.sql.DriverManager class. On modern JVMs the driver registers i...tself with the DriverManager automatically when the JDBC JAR is on the classpath (through Java's service-provider mechanism ), so no setup is needed. If that does not happen for s...tion before opening a connection: Class.forName("org.duckdb.DuckDBDriver"); Connection conn = DriverManager.getConnection("jdbc:duckdb:"); In GraalVM Native Image executables, always use this explicit load: the service-provider discovery is not relia... - https://man.mtool.work/duckdb/2.0/clients/java/connecting.html
