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.
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¶Regarding metadata:
Attention
Customers should ensure that no personal data (other than for a User object), sensitive data, export-controlled data, or other regulated data is entered as metadata when using the Snowflake service. For more information, see Metadata fields in Snowflake.
The following example sets a comment on the example_snapshot snapshot.
ALTER SNAPSHOT example_snapshot SET COMMENT = 'sample comment.';
