Class UserTaskCancellation

java.lang.Object

dev.frostlake.task.UserTaskCancellation

public final class UserTaskCancellation
extends Object

The one implementation of SYSTEM$USER_TASK_CANCEL_ONGOING_EXECUTIONS('task_name'), shared by the three surfaces that can reach it: the registered table function, and the two expression paths (SELECT SYSTEM$…() and SET v = SYSTEM$…()).

It cancels executions, not the task — a started task is still started afterwards. The name is echoed into the message exactly as it was passed while the lookup ignores case, and an unknown name raises rather than answering with a status row.
