Hi Folks,

In this article we are going to cover the Database size growth as a pivot table.

In this post we are going to discuss following points:

  • Problem Statement of SQL Script:
  • Description of SQL Script:
  • SQL Script Output Column
  • SQL Script Code
  • User Level to execute

    Problem Statement of SQL Script:

    Get Database size growth as a pivot table.

    Description of SQL Script:

    This Transact-SQL script uses the backup history to analyze the growth of the databases size over last twelve months and expose the average size of each month per database in a pivot table.
