SQL SERVER- partition table

 

 

 

 

 

 

 

- Create a partition function 
the CREATE PARTITION FUNCTION parfn_Date (a Date)
 AS RANGE   RIGHT  
the FOR  VALUES ( ' 2019-05-01 ' , ' 2019-06-01 ' ) 

- to view the partition function of 
the SELECT   *   the FROM   SYS.PARTITION_FUNCTIONS 

- Create a partition scheme 
the CREATE pARTITION SCHEME sch_parfn_Date
 AS pARTITION parfn_Date
  the TO ( [ Primary ] , FG1, fg2) 

 - View partitioning scheme 
 the SELECT   *   the FROM  SYS.PARTITION_schemes

  - Specifies the architecture and partitioning column, the column data type to the partition and the partition function of the same type of parameters
