Canceling an In-Progress Query

Documentation

• Snowflake SDK Documentation

You can cancel long-running queries using the cancel() method on the statement object.

Prerequisites

• You’ve established a connection to Snowflake and promisified it.

Example

import { scheduler } from 'node:timers/promises';

// Start a long-running query (simulates 10-second wait)
console.log('Starting query...', new Date());
const { statement } = connection.execute({
  sqlText: `CALL SYSTEM$WAIT(10, 'SECONDS')`
});

// Wait 2 seconds, then cancel
console.log('Waiting 2 seconds...', new Date());
await scheduler.wait(2000);

console.log("Canceling query...", new Date());
await statement.cancel();
console.log("Query canceled successfully");

// Note: If you were awaiting the original query's results,
// it would throw an error when canceled:
// Error [OperationFailedError]: SQL execution canceled
