Syntax¶
Parameters¶
nameSpecifies the identifier for the user-defined type to restore.
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 |
User-defined type |
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). |
Operating on an object in a schema requires at least one privilege on the parent database and at least one privilege on the parent 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¶
Restoring user-defined types is only supported in the current schema or current database, even if the type name is fully-qualified.
If a user-defined type with the same name already exists, an error is returned.
UNDROP relies on the Snowflake Time Travel feature. An object can be restored only if the object was deleted within the Data retention period. The default value is 24 hours.
