Der PartitionScheme-Typ macht folgende Elemente verfügbar.

Konstruktoren

	Name	Beschreibung
	PartitionScheme()	Initializes a new instance of the PartitionScheme class.
	PartitionScheme(Database, String)	Initializes a new instance of the PartitionScheme class, and sets the name of the partition scheme and the database to which it belongs.

Zum Anfang

Eigenschaften

	Name	Beschreibung
	Events	Gets the events associated with the partition function.
	ExtendedProperties	Represents a collection of ExtendedProperty objects. Each ExtendedProperty object represents an extended property defined on the PartitionScheme object.
	FileGroups	Represents a collection of FileGroup objects. Each FileGroup object represents a filegroup defined on the database.
	ID	Gets the zero-based ordinal of the PartitionScheme object, which specifies its position within the collection.
	Name	Gets or sets a String which contains the name of the PartitionScheme. (Überschreibt NamedSmoObject.Name.)
	NextUsedFileGroup	Gets or sets the name of the filegroup that has NEXT USED status.
	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. (Geerbt von SqlSmoObject.)
	State	Gets the state of the referenced object. (Geerbt von SmoObjectBase.)
	Urn	Gets the Uniform Resource Name (URN) address value that uniquely identifies the object. (Geerbt von SqlSmoObject.)
	UserData	Gets or sets user-defined data associated with the referenced object. (Geerbt von SmoObjectBase.)

	Create	Creates a partition scheme on the instance of SQL Server as defined by the PartitionScheme object.
	Discover	Discovers a list of type Object. (Geerbt von SqlSmoObject.)
	Drop	Removes an existing partition scheme.
	Equals	(Geerbt von Object.)
	FormatSqlVariant	Formats an object as SqlVariant type. (Geerbt von SqlSmoObject.)
	GetContextDB	Gets the context database that is associated with this object. (Geerbt von SqlSmoObject.)
	GetDBName	Gets the database name that is associated with the object. (Geerbt von SqlSmoObject.)
	GetHashCode	(Geerbt von Object.)
	GetPropValue	Gets a property value of the SqlSmoObject object. (Geerbt von SqlSmoObject.)
	GetPropValueOptional	Gets a property value of the SqlSmoObject object. (Geerbt von SqlSmoObject.)
	GetPropValueOptionalAllowNull	Gets a property value of the SqlSmoObject object. (Geerbt von SqlSmoObject.)
	GetServerObject	Gets the server of the SqlSmoObject object. (Geerbt von SqlSmoObject.)

	ResetNextUsed	Resets the NEXT USED status of the partition scheme that has been marked as NEXT USED.
	Script()	Generates a Transact-SQL script that can be used to re-create the partition scheme.
	Script(ScriptingOptions)	Generates a Transact-SQL script that can be used to re-create the partition scheme as specified by the script options.
	SetParentImpl	Sets the parent of the SqlSmoObject to the newParent parameter. (Geerbt von SqlSmoObject.)
	ToString	Returns a String that represents the referenced object. (Geerbt von SqlSmoObject.)

Hinweise

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.
