learn about sqlserver partitition and partition table 1
Dear all,
Let get into business, the partitions on sql server is very different with that on oracle.
I do not want to speak too much, Here is an example.
At beginning, we should create a partition function
CREATE PARTITION FUNCTION [PF_DATETIME_M_TEST](datetime) AS RANGE RIGHT FOR VALUES (N'2013-08-01T00:00:00.000',N'2013-09-01T00:00:00.000', N'2013-10-01T00:00:00.000', N'2013-11-01T00:00:00.000', N'2013-12-01T00:00:00.000', N'2014-01-01T00:00:00.000', N'2014-02-01T00:00:00.000', N'2014-03-01T00:00:00.000', N'2014-04-01T00:00:00.000', N'2014-05-01T00:00:00.000', N'2014-06-01T00:00:00.000', N'2014-07-01T00:00:00.000', N'2014-08-01T00:00:00.000', N'2014-09-01T00:00:00.000', N'2014-10-01T00:00:00.000', N'2014-11-01T00:00:00.000', N'2014-12-01T00:00:00.000', N'2015-01-01T00:00:00.000', N'2015-02-01T00:00:00.000', N'2015-03-01T00:00:00.000', N'2015-04-01T00:00:00.000', N'2015-05-01T00:00:00.000', N'2015-06-01T00:00:00.000', N'2015-07-01T00:00:00.000', N'2015-08-01T00:00:00.000', N'2015-09-01T00:00:00.000', N'2015-10-01T00:00:00.000', N'2015-11-01T00:00:00.000', N'2015-12-01T00:00:00.000', N'2016-01-01T00:00:00.000')
You seem, the partittion function is used to define partition key range,
Next we need to create partittion schema
CREATE PARTITION SCHEME [PS_DATETIME_M_TEST] AS PARTITION [PF_DATETIME_M_TEST] TO ([XXXXFG_initial],[XXXXFG_201308], [XXXXFG_201309], [XXXXFG_201310], [XXXXFG_201311], [XXXXFG_201312], [XXXXFG_201401], [XXXXFG_201402], [XXXXFG_201403], [XXXXFG_201404], [XXXXFG_201405], [XXXXFG_201406], [XXXXFG_201407], [XXXXFG_201408], [XXXXFG_201409], [XXXXFG_201410], [XXXXFG_201411], [XXXXFG_201412], [XXXXFG_201501], [XXXXFG_201502], [XXXXFG_201503], [XXXXFG_201504], [XXXXFG_201505], [XXXXFG_201506], [XXXXFG_201507], [XXXXFG_201508], [XXXXFG_201509], [XXXXFG_201510], [XXXXFG_201511], [XXXXFG_201512], [XXXXFG_201601])
GO
the partititon schema is to tell database which rang locate on which place --- filegroup.
Then we can go for generating partititon now.
