Optimization SQL Server DatabaseThere are many reasons for slow query speed, which are common in the following ways: 1. No index or no index is used (this is the most common problem of slow query and is a defect in programming) 2. Low I/O throughput, resulting in a bottleneck effect. 3. the query is not optimized because no computing column is created. 4. Insufficient memory 5. slow network speed 6. The que

On the forum, I often complained that SQL Server is too memory-consuming. Here I will give a brief introduction to memory-related tuning knowledge based on experience. First, describe the memory used by SQL Server. The memory occupied by SQL

In order to optimize the performance of Microsoft SQL Server most effectively, you must be clear about where performance will be maximized in terms of changing circumstances and focus on these aspects. Otherwise, you may spend a lot of time and effort on these issues, while performance is not significantly improved.Most of the following information does not addre
