	Urn	Gets the Uniform Resource Name (URN) address value that uniquely identifies the object. (Herdado de SqlSmoObject.)
	UserData	Gets or sets user-defined data associated with the referenced object. (Herdado de SmoObjectBase.)

Comentários

Partition functions are used to partition tables and indexes across multiple file groups.

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

To set PartitionFunction object propertied, users must ALTER permission on the database or ALTER ANY DATASPACE permission on the server, or be a member of the db_owner or db_ddladmin fixed database roles or a member of sysadmin fixed server role.

To create or drop a partition function, users must have ALTER permission on the database or ALTER ANY DATASPACE permission on the server, or be a member of the db_owner or db_ddladmin fixed database roles or a member of sysadmin fixed server role.

To merge or split the range values on the partition function, users must have ALTER permission on the database or ALTER ANY DATASPACE permission on the server, or be a member of the db_owner or db_ddladmin fixed database roles or a member of sysadmin fixed server role.

Thread Safety

Qualquer membro público estático (Compartilhado no Microsoft Visual Basic) desse tipo é seguro para operações multi-threaded. Não há garantia de que qualquer membro de instância seja seguro para threads.

Exemplos

Usando grupos de arquivos e arquivos para armazenar dados

Segurança de thread

Qualquer membro público static (Shared no Visual Basic) desse tipo é seguro para threads. Não há garantia de que qualquer membro de instância seja seguro para threads.
