DROP SNAPSHOT

Removes a snapshot. A snapshot is persisted data that the customer pays for. DROP SNAPSHOT tells Snowflake to delete that data. The data is no longer available for use as a snapshot and the customer no longer pays for it.

CREATE SNAPSHOT , ALTER SNAPSHOT, DESCRIBE SNAPSHOT, SHOW SNAPSHOTS

Syntax

DROP SNAPSHOT [ IF EXISTS ] <name>;
Copy

Parameters

name

Specifies the identifier for the snapshot to drop.

If the identifier contains spaces or special characters, the entire string must be enclosed in double quotes. Identifiers enclosed in double quotes are also case-sensitive.

Access control requirements

A role used to execute this SQL command must have the following privileges at a minimum:

Privilege

Object

Notes

OWNERSHIP

Snapshot

OWNERSHIP is a special privilege on an object that is automatically granted to the role that created the object, but can also be transferred using the GRANT OWNERSHIP command to a different role by the owning role (or any role with the MANAGE GRANTS privilege).

Note that operating on any object in a schema also requires the USAGE privilege on the parent database and schema.

For instructions on creating a custom role with a specified set of privileges, see Creating custom roles.

For general information about roles and privilege grants for performing SQL actions on securable objects, see Overview of Access Control.
