Automatic tuning SQL Server identifies and fixes performance issues caused by query execution plan choice regressions. Automatic tuning in Azure SQL Database and SQL database in Microsoft Fabric also creates necessary indexes and drops unused indexes. For more information on query execution plans, see...
ALTER DATABASE <yourDatabase> SET AUTOMATIC_TUNING ( FORCE_LAST_GOOD_PLAN = ON ); 启用此选项后,数据库引擎会自动强制使用具有以下特征的任何建议:预计 CPU 性能提升超过 10 秒,或新计划中的错误数多于建议计划中的错误数,且经验证强制计划优于当前计划。要...
ALTERDATABASE<yourDatabase>SETAUTOMATIC_TUNING ( FORCE_LAST_GOOD_PLAN =ON); 一旦您啟用此選項,資料庫引擎就會自動強制執行估計的 CPU 增量高於 10 秒,或新計畫錯誤數目高於建議計畫錯誤數目的任何建議,並確認強制執行的計畫比目前的計畫更好。 若要在 Azure SQL 資料庫 和 Azure SQL 受控執行個體 中啟用自...
