This script returns the highest-impact missing index recommendations based on cumulative workload statistics. It helps identify tables where SQL Server believes additional indexes could significantly improve query performance.
This is useful during performance tuning, workload reviews, and when investigating high read activity or inefficient query plans.
The Script
Example Output
The result set shows the top missing index recommendations ordered by calculated impact score. It includes database name, table name, usage statistics, and a suggested CREATE INDEX statement.
This helps prioritise which potential indexes may deliver the greatest performance benefit.
Notes
- Based on cumulative statistics since last restart
- Recommendations are not always optimal and should be reviewed carefully
- May suggest overlapping or duplicate indexes
- Intended as a tuning starting point, not automatic implementation
