为什么80%的码农都做不了架构师?>>>
1. 建立分区存储的文件组(filegroup)和文件(file)
ALTER DATABASE Student ADD FILEGROUP [studentdata01];
ALTER DATABASE Student ADD FILEGROUP [studentdata02];
ALTER DATABASE Student ADD FILEGROUP [studentdata03];
ALTER DATABASE Student ADD FILEGROUP [studentdata04];
ALTER DATABASE Student
ADD FILE(
NAME=N'studentdata01',
FILENAME='C:\Program Files\Microsoft SQL Server\MSSQL12.SSCCMDB\MSSQL\DATA\studentdata01.ndf',
SIZE=5MB,
MAXSIZE=100MB,
FILEGROWTH=5MB
)TO FILEGROUP [studentdata01]
ALTER DATABASE Student
ADD FILE(
NAME=N'studentdata02',
FILENAME='C:\Program Files\Microsoft SQL Server\MSSQL12.SSCCMDB\MSSQL\DATA\studentdata02.ndf',
SIZE=5MB,
MAXSIZE=100MB,
FILEGROWTH=5MB
)TO FILEGROUP [studentdata02]
studentdata03, studentdata04略
2. 创建分区函数
Use Student
CREATE PARTITION FUNCTION Studentdata_Partition_Function (datetime)
AS RANGE RIGHT
FOR VALUES ('2017-04-01T00:00:00','2017-07-01T00:00:00','2017-10-01T00:00:00')
3. 创建分区方案
Use Student
CREATE PARTITION SCHEME Studentdata_Partition_SCHEME
AS PARTITION Studentdata_Partition_Function
TO (studentdata01, studentdata02, studentdata03, studentdata04)
4. 创建分区表和分区索引:
Use Student
CREATE TABLE StudentData
(
GradeID int NOT NULL,
ClassID int NOT NULL,
StudentID int NOT NULL,
Datetime datetime NOT NULL,
Data float(4) NOT NULL
)ON Studentdata_Partition_SCHEME([Datetime]) ;
CREATE CLUSTERED INDEX DatetimeIndex
ON StudentData
(
Datetime
) WITH (SORT_IN_TEMPDB = OFF, IGNORE_DUP_KEY = OFF, DROP_EXISTING = OFF, ONLINE = OFF, FILLFACTOR = 95)
ON Studentdata_Partition_SCHEME ([Datetime]);
