Understanding and Troubleshooting Parameter Sniffing in SQL Server
What is Parameter Sniffing in SQL Server? Parameter sniffing is a well-known performance issue in SQL Server that can cause unexpected slowdowns in query performance. The problem arises when the query optimizer uses a plan that is optimal for a specific set of parameter values, but not for others. This can lead to suboptimal performance when the query is executed with different parameter values. In this article, we will explain what parameter sniffing is, how it can affect query performance, and how to troubleshoot and prevent it. We will also provide some best practices for avoiding parameter sniffing in the
