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 사용자 지정 역할 만들기.

For general information about roles and privilege grants for performing SQL actions on securable objects, see 액세스 제어의 개요.

Usage notes¶

Snowflake doesn’t support undropping storage lifecycle policy objects.
If a table column has a storage lifecycle policy attached to it, you can’t drop the column from the table.
You can’t drop a database or schema that contains a storage lifecycle policy attached to an object that belongs to a different database or schema.
You can’t drop a storage lifecycle policy that is attached to a table. Remove the policy association before dropping the storage lifecycle policy.
When you undrop a table or schema with an attached policy, the policy association is restored.

Examples¶

The following example drops the storage lifecycle policy named example_slp:

DROP STORAGE LIFECYCLE POLICY example_slp;

Copy

Output:

+-----------------------------------+
