Removes a task from the current/specified schema.
DROP TASK [ IF EXISTS ] <name>
Specifies the identifier for the task to drop. If the identifier contains spaces, special characters, or mixed-case characters, the entire string must be enclosed in double quotes. Identifiers enclosed in double quotes are also case-sensitive (e.g.
If the task identifier is not fully-qualified (in the form of
schema_name.task_name), the command looks for the task in the current schema for the session.
When a task is dropped, any current run of the task (i.e. a run with an EXECUTING state in the TASK_HISTORY output) is completed. To abort the run of the specified task, execute the SYSTEM$USER_TASK_CANCEL_ONGOING_EXECUTIONS function.
The root task in a tree of tasks must be suspended before any task in the tree is dropped.
A standalone task can be dropped by the task owner (i.e. the role that has the OWNERSHIP privilege on the task) or a higher role without first suspending the task.
If a predecessor task in a tree of tasks is dropped, then all former child tasks that identified this task as the predecessor become either standalone tasks or root tasks, depending on whether other tasks identify these former child tasks as their predecessor. These former child tasks are suspended by default and must be resumed manually.
Drop a task:
SHOW TASKS LIKE 't2%'; DROP TASK t2; SHOW TASKS LIKE 't2%';
Drop the task again, but don’t raise an error if the task does not exist:
DROP TASK IF EXISTS t2;
