During the recent development of the SQL Server database project, a problem was found in the background site memory consumption of 95%, through the Task Manager to view the memory of the process Sqlserver.exe, because SQL Server R

SQL Server servers run for a while to discover that memory has soared to 98% (the first time this problem was thought to be a virus, Trojan, system to crash ...) Later, I have been groping for some time to share our experience.Workaround: Restarting the host Restart SQL

SQL statements that execute a plan that consumes large amounts of memory and that are reused less frequently. See if it is reasonable to call the method. In addition, you can analyze the execution plan by using more frequently repeated SQL statements to see if the execution plan has been optimized. Further, through the analysis of the query plan, we can find som
