A database system processes database queries that process external tables representing data obtained from an external systems. The database system generates an execution plan to execute the database query. The database system sends a request for data of the external table to an external system. The request provides connection information to the external system. The external system sends a request to connect to the database system and provides data of the external table as a data stream. If the database system reaches an operator that processes the data of the external table, the database system waits for data from the external system. The database system processes the database query using the data of the data stream. The database system provides the result of the database query to a requestor, for example, a client device.
