SQL Server diagnostics
- Use estimated execution plans when you need plan shape without executing the query.
- SET STATISTICS IO and SET STATISTICS TIME require executing the statement.
- Actual execution plans execute the statement and should be collected only when safe.
- Existing nonclustered indexes and row counts improve recommendation quality.
Privacy and review notes
- SQLito does not connect to SQL Server or execute commands.
- Collect actual diagnostics in staging or on safe SELECT statements.
- Do not paste customer data, emails, database names, server names, or production secrets.
SQL Server optimizer FAQ
Can I paste SQL Server STATISTICS IO output?
Yes, after redaction. Remember that collecting it requires running the statement.
Does SQLito recommend index rebuilds?
SQLito focuses on query shape and indexing ideas. Maintenance actions need workload-specific DBA review.
