1.创建分区函数 CREATE PARTITION FUNCTION xx1(int) 解释:在当前数据库中创建一个函数,该函数可根据指定列的值将表或索引的各行映射到分区。 语法: 1 2 3 4 CREATEPARTITIONFUNCTIONpartition_function_name ( input_parameter_type ) ASRANGE [LEFT|RIGHT] FORVALUES( [ boundary_value [ ,...n ] ] ) [...

通过将 Transact-SQL CREATE INDEX 语句与 DROP EXISTING = ON 子句一起使用来删除并重新生成现有的已分区索引。 运行一系列 ALTER PARTITION FUNCTION 语句。 ALTER PARTITION FUNCTION 所影响的全部文件组都必须处于联机状态。 如果使用分区函数的任何表中存在已禁用的聚集索引,ALTER PARTITION FUNCTION 将失败。
这里先创建Partition Function以及Partition Scheme,之后在分区列上创建聚集索引并按照分区方案分区,最后删除了这一索引。 2.在表有索引的情况下: 如果原先没有聚集索引: CREATE CLUSTERED INDEX[ClusteredIndex_on_TestScheme_634025229911990663]ON[dbo].[Account]([birthday])WITH(SORT_IN_TEMPDB=OFF,IGNORE_DUP_KEY=...
Cannot drop the partition function 'function_name', because it does not exist or you do not have permission. Resolution This issue was first fixed in the following cumulative update for SQL Server: Cumulative Update 6 for ...
Microsoft SQL Server 2005 does not provide replication support for modifying a partition function. Changes to a partition function in the publication database must be manually applied in the subscription database. Permissions Any one of the following permissions can be used to execute ALTER PARTITION...
The Partition function is used first to establish these ranges, then the SQL Count function counts the number of orders in each range. In this example, the arguments to the Partition function are start = 0, stop = 500, interval = 50. The first range would therefore be 0:49, and so ...
