SQL Performance

One of the more perplexing problems to troubleshoot in SQL Server can be those related to memory grants. SQL Server’s optimizer estimates how much memory is needed, and the query must obtain the memory grant in order to start executing. ALTER DATABASE [ WideWorldImporters ] SET QUERY_STORE = ON ; GO. sort, hash).
