含內嵌工作負載的 XML 輸入檔範例 (DTA)

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 ServerDatabaseSchemaTableWorkloadEventStringTuningOptions 等元素的值。如需有關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。

註解

您可以在 EventString 元素所包含的內嵌工作負載中,指定 USE database_name 陳述式。
