Posted on dev.to, a Spring JDBC demo splits a five-role, ten-filter SQL Server search into two Strategy families that feed one rule-enforcing query builder. The legacy version buries a delegation rule in five appends and fetches admin-only emails for every role.

sys.dm_db_index_usage_stats counts seeks, scans and lookups only since the instance came up, so an index with no reads may just be waiting for its monthly job. One cross join puts that window in the report.

A dev.to walkthrough automates restore plus CHECKDB on a scratch instance. The interesting part is why homegrown versions fail: backup history lives in msdb on the server you are trying to prove.
