含內嵌工作負載的 XML 輸入檔範例 (DTA)
適用於：
SQL Server
請複製利用 EventString 元素指定工作負載的這個 XML 輸入檔範例，再將它貼到您喜愛的 XML 編輯器或文字編輯器中。 您可以利用 EventString 元素，在 XML 輸入檔中指定 Transact-SQL 指令碼工作負載，而不使用個別的工作負載檔案。 將這個範例複製到編輯工具之後，請利用您的特定微調工作階段的各個值來取代指定給 Server、 Database、 Schema、 Table、 Workload、 EventString和 TuningOptions 等元素的值。 如需可以搭配這些元素來使用的所有屬性和子元素的詳細資訊，請參閱 XML 輸入檔參考 (Database Engine Tuning Advisor)。 下列範例只用到部份可用的屬性及子元素選項。
