首先,先验证下Cacti数据是否准确,已知Cacti数据是从SQLServer的sys.dm_os_performance_counters 计数器DMV中取数的。所以查询下数据: 1 2 3 select* fromsys.dm_os_performance_counters wherecounter_name ='Active Temp Tables' 查询结果和图中展示数据没有差别 然后,查询
优化Temp表的使用可以大大提高SQL Server的性能。通过使用局部临时表、临时表变量、索引和适当使用Temp表等方法,我们可以最大限度地减少Temp表对性能的影响,并提高查询的执行效率。最后,需要根据具体情况权衡利弊,选择最适合的临时数据存储方式。 参考资料:[Microsoft Docs - Temporary Tables]...

答:從 SQL Server 2000 的觀點來看,唯一支援的原生 64 位元架構是 Intel 的 ia64。因此,SQL Server 2000 所謂的 64 位元支援是指 ia64。原生 64 位元 ia64 唯一支援的 SQL Server 2000 版本是 Enterprise Edition 版。既沒有像原生 64 位元應用程式一樣在 ia64 上執行的 SQL Server 2000 Standard Edition...
问题:如果我运行 64 位版的 Windows Server® 操作系统,则必须使用 SQL Server 2000 Enterprise Edition(64 位)而不能使用 32 位 SQL Server 2000,对吗? 解答:从 SQL Server 2000 观点看,所支持的唯一纯 64 位体系结构是 Intel 的 ia64。因而,如果 SQL Server 2000 中涉及 64 位支持,指的是 ia64。纯...
