Synopsis

cancel( query_id )

Summary

The cancel operator cancels and aborts a currently running query by query id.  Obtain the query id value from the SciDB log or via the list('queries') command. SciDB maintains query context information for each completed and in-progress query in the server. If you issue a Ctrl+C or abort from the iquery client, SciDB aborts the query aborts and removes its context from the server.

In Enterprise Edition security mode, administrative privileges are required to cancel the queries of other users.
