Osservazioni

To get UserDefinedDataType object permissions, users can be a member of the public fixed server role.

To set UserDefinedDataType object permissions, users must have CREATE TYPE permission in the parent database and ALTER permission on specified schema. If an assembly is specified, users must either own the assembly or have REFERENCES permission on it.

To create an user-defined data type data type, users must have CREATE TYPE permission in the parent database and ALTER permission on specified schema. If an assembly is specified, users must either own the assembly or have REFERENCES permission on it.

To drop a user-defined data type data type, users must have CONTROL permission on the type and ALTER permission on the specified schema.
