	Parent	Gets or sets the Database object that is the parent of the PartitionScheme object.
	PartitionFunction	Gets or sets the name of the partition function used in this partition scheme.
	Properties	Gets a collection of Property objects that represent the object properties. (hérité de SqlSmoObject.)
	State	Gets the state of the referenced object. (hérité de SmoObjectBase.)
	Urn	Gets the Uniform Resource Name (URN) address value that uniquely identifies the object. (hérité de SqlSmoObject.)
	UserData	Gets or sets user-defined data associated with the referenced object. (hérité de SmoObjectBase.)

Notes

Partition schemes define the physical structure that is used to partition tables and indexes across multiple file groups.

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

To set PartitionScheme object properties, users must use the ALTER statement to alter permission on the database or ALTER ANY DATASPACE for permissions on the server or be a member of the db_owner or db_ddladmin fixed database roles or sysadmin fixed server role.

To create or drop a partition scheme, users must use ALTER for permission on the database or ALTER ANY DATASPACE for 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

Tout membre statique public (Partagé dans Microsoft Visual Basic) de ce type est sûr dans le cadre des opérations à plusieurs threads. Tous les membres de l'instance ne sont pas garantis comme étant thread-safe.

Exemples

Utilisation de fichiers ou de groupes de fichiers pour stocker des données

Sécurité des threads

Tous les membres publics static (Shared dans Visual Basic) de ce type sont thread-safe. Tous les membres de l'instance ne sont pas garantis comme étant thread-safe.
