summary: Terminates a function during execution.
syntax_fmt: FUNCTION KILL
title: FUNCTION KILL
---
Kill a function that is currently executing.

The `FUNCTION KILL` command can be used only on functions that did not modify the dataset during their execution (since stopping a read-only function does not violate the scripting engine's guaranteed atomicity).
