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.

Thread Safety

此类型的任何公共静态（Microsoft Visual Basic 中的 Shared）成员在多线程操作中是安全的。但不保证所有实例成员都是线程安全的。

示例

使用文件组和文件存储数据
