Label:In the first step we describe how to customize a trace in the profiler and let it run on the server side to create a trace file. We then converted the trace definition to the script that created the extended Events session through the sp_sqlskills_converttracetoextendedevents stored procedure of Jonathan Kehayias. Hopefully it's a bridge for you to start with SQL Trace leading to extended events. Of course, it also provides an effective way to c

Specify a unique uniqueID for each element.2. Use an independent function to create a listener. However, this function does not directly reference the element to avoid circular reference.3. The created listener is co
