PartitionFunction 类型公开以下成员。
构造函数
名称 | 说明 | |
---|---|---|
PartitionFunction() () () () | Initializes a new instance of the PartitionFunction class. | |
PartitionFunction(Database, String) | Initializes a new instance of the PartitionFunction class for the specified database and with the specified name. |

属性
名称 | 说明 | |
---|---|---|
CreateDate | Gets the date and time when the partition function was created. | |
Events | Gets the events associated with the partition function. | |
ExecuteForScalar | Gets or sets the Boolean property value that specifies whether the object is set to the execute for scalar option. (从 SqlSmoObject 继承。) | |
ExtendedProperties | Represents a collection of ExtendedProperty objects. Each ExtendedProperty object represents an extended property defined on the partition function. | |
ID | Gets the zero-based ordinal of the PartitionFunction object, which specifies its position within the collection. | |
IsTouched | Gets the Boolean property value that specifies whether the object properties have been updated but not yet persisted on the server. (从 SqlSmoObject 继承。) | |
Name | Gets or sets the name of the object. (从 NamedSmoObject 继承。) | |
NumberOfPartitions | Gets the number of partitions. | |
ObjectInSpace | Gets the Boolean property value that specifies whether the object exists in isolation, or whether it is directly or indirectly connected to the instance of SQL Server. (从 SqlSmoObject 继承。) | |
Parent | Gets or sets the Database object that is the parent of the PartitionFunction object. | |
PartitionFunctionParameters | Represents a collection of PartitionFunctionParameter objects. Each PartitionFunctionParameters object represents a partition function parameter defined on the partition function. | |
Properties | Gets a collection of Property objects that represent the object properties. (从 SqlSmoObject 继承。) | |
RangeType | Gets or sets the placement of boundary values in relation to the interval. | |
RangeValues | Gets or sets range values that define the distribution of the partition function. | |
ScalarResult | Gets the scalar result for the referenced object. (从 SqlSmoObject 继承。) | |
State | Gets the state of the referenced object. (从 SmoObjectBase 继承。) | |
Urn | Gets the Uniform Resource Name (URN) address value that uniquely identifies the object. (从 SqlSmoObject 继承。) | |
UserData | Gets or sets user-defined data associated with the referenced object. (从 SmoObjectBase 继承。) |

注释
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.
