The purpose of this document is to describe different ways of improving the performance of SQL Server queries. Most of this document will describe index optimization, with occasional references to particular cod
Although significant amounts of time can be spent executing code in the client or application server processes, you'll often find that the most time-consuming step turns out to involve the execution of SQL.doi:10.1007/978-1-4302-3708-2_11David Kurtz...

Top 10 steps to optimize data access in SQL Server: Part III (Apply advanced indexing and denormalization) As you might have seen already, we have gone through seven optimization steps so far. Let us proceed to step 8 now: Step 8: Diagnose performance problems, and use SQL Profiler and th...
(6)Adaptive optimization and self-tuning techniques 使用自调优技术来简化系统管理的任务,并减轻estimation误差的影响,这本身就产生了调优和验证方面的挑战。例如,SQLServer的自动更新统计数据的策略对于某些客户场景可能过早发生,导致不必要的CPU和I/O消耗,而对于其他场景,它可能过晚发生,导致代价评估不准想。一些能够...

Applying theJOINoperation from a larger table to a smaller table is a common SQL optimization technique. Because joining from a larger table to a smaller table will make your query to execute faster. If we apply aJOINoperation from a smaller table to a larger table, our SQL engine has to...
It’s easy to start tinkering with the gears of SQL query optimization. You open up SQL Server Management Studio (SSMS), monitor wait time, review theexecution plan, gather object information and begin optimizing SQL until you’re running a finely tuned machine. ...
