DROP SNAPSHOT¶

Note

This operation is not currently covered by the Service Level set forth in Snowflake’s Support Policy and Service Level Agreement.

Removes a snapshot of a block storage volume. 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.

See also:

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.

For more information, see Identifier requirements.

Access control requirements¶

A role used to execute this operation 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).

The USAGE privilege on the parent database and schema are required to perform operations on any object in a schema. Note that a role granted any privilege on a schema allows that role to resolve the schema. For example, a role granted CREATE privilege on a schema can create objects on that schema without also having USAGE granted on that 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.

Usage notes¶

  • When the IF EXISTS clause is specified and the target object doesn’t exist, the command completes successfully without returning an error.
