:LIMIT

Purpose

Limits the number of values retrieved by a query.

Parameters

integer: The maximum number of values allowed.
clause: A non-ground clause containing ?variable.

Examples

  (:LIMIT 30 (:INSTANCE :THING ?inst))

Success criteria

Always succeeds if the clause succeeds.

Failure criteria

Fails if the clause fails.

Notes

The LIMIT command performs the query and then removes any extra values from the end of the list returned by the KBMS. Algernon does not guarantee that values will always be returned in the same order, however the backend KB may.
