ON PRIMARY ( NAME = N'Staging_TST', FILENAME = N'C:\Program Files\Microsoft SQL Server\MSSQL11.SQL2012\MSSQL\DATA\Staging_TST.mdf', SIZE = 28672KB, MAXSIZE = UNLIMITED, FILEGROWTH = 1024KB ) If exists(Select name from sys.databases where name = 'Staging_TST') The below script will create physical data files, file groups, partition scheme, Partition will accept data between and Dec 31, 2017. Initially partition one will accept data until Novemand the second This table will be created with 3 partitions to accept data on a monthly basis. In this example, I have created an Orders table with order date as the partition Step5: Merge the old partition with the new boundary.Step4: Split the right most partition based on a new boundary.Step3: Prepare the filegroup to accept new boundaries.Step2: Purge or archive data from the work table.Step1: Switching partition between main and work table.There are 5 steps to implement in the Sliding Window Partition: Sliding Window Partition Steps in SQL Server Partition switching can be accomplished by using the "ALTER TABLE SWITCH" SQL Server will throw an exception and will provide a detailed error message. If you try to switch the partition without satisfying any of the criteria, the Both the source and target tables must be in the same filegroup.Both the source and target table must use the same column as the partition column.Source and target tables must have identical columns and indexes.The following criteria must be met for partition switching: Hence in a repeated/circular method, we try to use the sameĭata files/filegroups again and again. We purge/archive an old partition and we reuse that partition In sliding window methodology, we don’t create new files/file group when The old data can be switched to a work (Staging) table and then the data in the As this is a metadata-only operation, no data movement will Partition switching will allow you to move a partition between source and target This methodology is also known as “Sliding Partitioning”. In this tip, I will walkthrough a method to purge data using partition The classical delete command on the partitioned tableĭatabase transaction log quickly and it may take a very long time to complete As the business grows over a period of time, it is mandatory to archive or purge
