Update improves the SUMMARIZE function, the DIVDE function, and the caching feature in SQL Server 2012


Microsoft distributes Microsoft SQL Server 2012 fixes as one downloadable file. Because the fixes are cumulative, each new release contains all the hotfixes and all the security fixes that were included with the previous SQL Server 2012 fix release.

Introduction

This article introduces an update for SQL Server 2012 that includes the following improvements:
  • Prevents optimization code-paths from being added to SUMMARIZE functions unnecessarily.
  • Prevents In-memory Business Intelligence (IMBI) caches for some operations from being cleared.
  • Improves performance of the DIVDE function.
