XML Input File Sample with Inline Workload (DTA)

  • Άρθρο

Applies to: SQL Server

Copy and paste this sample of an XML input file that specifies a workload with the EventString element into your favorite XML editor or text editor. You can use the EventString element to specify a Transact-SQL script workload in the XML input file instead of using a separate workload file. After copying this sample into your editing tool, replace the values specified for the Server, Database, Schema, Table, Workload, EventString, and TuningOptions elements with those for your specific tuning session. For more information about all of the attributes and child elements that you can use with these elements, see the XML Input File Reference (Database Engine Tuning Advisor). The following sample uses only a subset of available attribute and child element options.
