Databricks Serverless SQL supports JDBC reads (queries) via the Databricks SQL endpoints, but JDBC writes (inserts/updates) directly from serverless compute are not generally supported. This is a common limitation because serverless SQL endpoints are optimized for analytics workloads (read-heavy), not for transactional or ETL-style writes via JDBC.

Hello! And what is the standard way to write to a external database through databricks? general purpose compute?

Thanks very much.
