About the DuckDB JDBC driver

A JDBC driver is a Java .jar library that lets applications connect to DuckDB. DbSchema uses JDBC to reverse engineer schemas, run SQL, and generate documentation. Driver files are usually published by the database vendor or an open-source project.

JDBC URL format

Host, port, database name, and SSL options are passed in a URL starting with jdbc:. Each DuckDB driver uses its own syntax — see the connection details below.

The DuckDB JDBC driver

DuckDB is an embedded OLAP database designed for analytical workloads directly inside your application process, with no separate server required. It reads Parquet, CSV, and JSON files natively and integrates with Python, R, and Java, making it popular for local data analysis and data pipeline testing.

The DuckDB JDBC URL

  • Required File(s): duckdb_jdbc-xxx.jar
  • Java Driver Class: org.duckdb.DuckDBDriver
  • JDBC URL: jdbc:duckdb:{FILE}
  • Website: DuckDB

Download DuckDB JDBC Driver

The driver archive is a zip file. Extract it and load the .jar files using DbSchema's Driver Manager.

DbSchema and DuckDB

DbSchema connects to DuckDB using the official JDBC driver and renders the in-process schema as a visual diagram. This is especially useful for teams using DuckDB as a local data warehouse, where DbSchema's table editor and query builder accelerate schema iteration.

After the JDBC driver connects, you get ER diagrams, SQL editor, schema sync, and HTML documentation in one desktop app. Compare DbSchema editions.

ER diagrams

Reverse engineer DuckDB into an interactive diagram and edit structures visually.

SQL & query builder

Run SQL with autocomplete or compose queries without writing every join by hand.

Schema documentation

Export HTML docs your team can browse without installing DbSchema.
