Performance is a big deal. No matter if we’re talking about applications in which users click buttons to display data or if we’re writing a query directly into let’s say SQL Server Management Studio (SSMS). Nobody likes to click a button, go get a coffee, and hope the results are...
Microsoft SQL Server has a limit on the number of parameters that a parameterized query can have (2100). However, many of our queries have a total number of IDs selected far greater. Currently we are using batches of IDs with parameterized queries to extract the entire set. However, these ...
选择Server 选项卡。 3. 在Query Optimizer 下选择 SQL Plan Control。 4. 选择SQL Plan Baseline 选项卡。 5. 在Settings 下,针对 Capture SQL Plan Baselines 选择 FALSE。 6. 针对参数 optimizer_capture_sql_plan_baseline 选择TRUE 值,然后单击 OK。 7. 参数现在设为 TRUE。 8. 打开SQ...
Understanding the reason for slowness of a SQL query and then tuning to boost it is a slightly complicated process, but it can be extremely rewarding in some cases. In this post, I am going to list down some ways in which you can tune the query performance for SQL Server Compact, along...
SQL Server查询存储是一种性能监视工具,可以帮助我们根据几种不同的性能指标(例如,CPU和内存消耗,执行时间以及查询消耗的I / O周期)评估SQL查询的性能。 查询存储类似于窗口“任务管理器”。 任务管理器提供有关进程的CPU,内存,网络和磁盘消耗的信息。 同样,查询存储可提供对相似信息的洞察力。

1在极端情况下,查询存储可能由于内部错误而进入 ERROR 状态。 从 SQL Server 2017 (14.x) 开始,如果出现这种情况,可通过在受影响的数据库内执行sp_query_store_consistency_check存储过程来恢复查询存储。 请参阅sys.database_query_store_options,了解actual_state_desc列说明中所述的详细信息。
