SQL Server Missing Indexes Report: dm_db_missing_index

Sat, 28 Feb 2026 00:00:00 +0000

SQL Server tracks index recommendations automatically as queries execute, storing them in the missing index DMVs. This T-SQL script queries those views to produce a ranked report of missing indexes, ordered by the estimated improvement they would provide, along with a ready-to-run CREATE INDEX statement for each recommendation.

Purpose and Overview

Every time SQL Server executes a query that would benefit from an index that does not exist, it records the recommendation in sys.dm_db_missing_index_details. Over time these recommendations accumulate and can reveal the highest-impact indexing changes you can make to improve query performance.
