Usage Notes

  • A user can cancel their own running SQL operations using this SQL function. Canceling running operations executed by another user requires a role with one of the following privileges:

    • OWNERSHIP on the user who executed the operation.

    • OPERATE or OWNERSHIP on the warehouse that is running the operation (if applicable).

    Note that the ACCOUNTADMIN role is not necessarily granted any of these privileges.

  • Snowflake query IDs are UUID text strings with hyphens, which are special characters, so the strings must be escaped using single quotes.

  • This function is not intended for canceling queries for a particular warehouse or user. Instead, use:


SELECT SYSTEM$CANCEL_QUERY('d5493e36-5e38-48c9-a47c-c476f2111ce5');

| SYSTEM$CANCEL_QUERY('D5493E36-5E38-48C9-A47C-C476F2111CE5') |
| query [d5493e36-5e38-48c9-a47c-c476f2111ce5] terminated.    |
