    XMLWordPrintable

Details

    Description

      Enable history partitions rotation with AUTO argument to specify maximum number of partitions kept in the table:

      create table t1 (x int) with system versioning
      		 
      partition by system_time interval 1 hour auto 25;
      		 
       
      		 
      create table t1 (x int) with system versioning
      		 
      partition by system_time interval 1 month auto 13;

      Or with explicit partitions:

      create table t1 (x int) with system versioning
      		 
      partition by system_time interval 1 hour auto 25
      		 
      (partition p0 history, partition pn current);
