Capture the last actual execution plan with LAST_QUERY_PLAN_STATS, inspect runtime rows, and understand what cache retention cannot provide.
Why Queries Recompile
Why queries recompile becomes clearer when you capture Extended Events causes and check schema changes, statistics, SET options, and temp tables.
Caching Query Results in the Application
Caching query results in the application can reduce repeated reads when ownership, expiry, invalidation, and memory cost are clear.
SEQUENCE Cache Size, Gaps and Insert Throughput
Compare SEQUENCE cache size, restart gaps, rollback gaps, and insert throughput with CACHE 50, CACHE 1000, and NO CACHE.
Sequence Gaps: Why NEXT VALUE FOR Skips Numbers
Explain sequence gaps, inspect cached values, test rollback behavior, and separate SQL Server identifiers from gapless numbering.
Report Caching and Snapshots in SSRS
Report caching and snapshots in SSRS reduce repeated database work when freshness rules, parameter combinations, and schedules are clear.
SQL SERVER – Stored Procedure are Compiled on First Run – SP taking Longer to Run First Time
Why does a stored procedure take longer the first time? Stored procedures are not pre-compiled; each one is compiled on first run and cached after that.
