含內嵌工作負載的 XML 輸入檔範例 (DTA)

適用于: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。 您可以使用 EventString 元素,在 XML 輸入檔中指定 Transact-SQL 腳本工作負載,而不是使用不同的工作負載檔案。 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 ServerDatabaseSchemaTableWorkloadEventStringTuningOptions 等元素的值。 如需您可以搭配這些元素使用之所有屬性和子專案的詳細資訊,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。
