I'm creating a web application where there is a table with frequency filter. The options that you can choose within the filter are Monthly, Weekly, Daily, and No Frequency. Anyone know a term that describes No Frequency in a single word? When a user chooses a frequency option, it only displays reports related to that particular frequency. No frequency reports are those happen in an ad hoc manner. I could use the word Ad Hoc. But, I just don't like the word...
Some more possibilities, with their (perceived) connotations:
Unscheduled: there is not a schedule associated with the report, it will never run automatically.
One-Time or One-time-only: the report was requested on a single specific occasion, no additional automated executions were requested or configured
Manual: The report is available to be run "on request" but is not set to run on a schedule
Miscellaneous frequency seems appropriate:
A series of reports with a miscellaneous frequency would have no specified frequency, and the outcome would be an ad hoc time pattern between reports.
I assumed that you didn't mean there is no frequency, rather that there is no regular pattern. In which case
Seems close to what you mean. Alternatives
All (if you show everything)
Others (if effectively you are selecting all those reports not selected by the regular frequency options).
My guess is that Others is actually the best; you allow selection of various kinds of regular reports, this final option selects everything else.
Given your comment, you have reports that occur exactly once; no recurrence, no frequency. I don't think most folks would parse "no frequency" to mean what you intend - witness the answers you've received.
In which case:
I favour one-off.
I think the word you need is impromptu. The 'no frequency' reports are clearly sent out according to no planned schedule. That makes them impromptu reports.
You can use on-demand to refer to those reports that weren't scheduled and were generated whenever someone wanted them.
Given the additional information that the report runs only once --which is not clear from the original question --a good word would be Non-repeating.
The typical wording for a task scheduler is One Time Only. This is the most clear and unambiguous for a user interface. You can use variants like Once, Once Only, One Time, Run Once, Run One Time.
From Microsoft's Configure a Scheduled Task Item (Windows 7). Triggers: If creating, updating, or replacing a task, configure when the task begins and the frequency with which to run the task on the Triggers tab. For a task scheduled to run daily, weekly, monthly, or one time only, select the start time at which to begin the task.
From IBM's DB2 administrative task scheduler, Defining task schedules for the administrative task scheduler. The following task definitions show some common scheduling options. To define "a task that executes one time only", set max_invocations to 1.
From MySQL Using the Event Scheduler :: Event Scheduler Overview An event performs a specific action according to a schedule... An event's timing can be either one-time or recurrent. A one-time event executes one time only. A recurrent event repeats its action at a regular interval.
From MySQL Event Scheduler Configuration: Type: The event repetition type, either ONE TIME (transient) or RECURRING (repeating).
You may also want some variant of Run Once or Run One Time.
The correct word for absence of frequency is "static." If you want something more flowery try "unperturbed"; for pithiness you could use "flat." It all depends on the context. Hope this helps.
