DROP PARTITION FUNCTION (Transact-SQL)
Removes a partition function from the current database. Partition functions are created by using CREATE PARTITION FUNCTION and modified by using ALTER PARTITION FUNCTION.
Any one of the following permissions can be used to execute DROP PARTITION FUNCTION:
ALTER ANY DATASPACE permission. This permission defaults to members of the sysadmin fixed server role and the db_owner and db_ddladmin fixed database roles.
CONTROL or ALTER permission on the database in which the partition function was created.
CONTROL SERVER or ALTER ANY DATABASE permission on the server of the database in which the partition function was created.
The following example assumes the partition function myRangePF has been created in the current database.
DROP PARTITION FUNCTION myRangePF;
