How to query extended events target XML in SQL Server?
With SQL Server 2012 came the GUI – a new session wizard, a new session dialog box, the (not-recommended) ability to view live data, and the ability to see the information you collected. But that didn’t solve the root problem for me – all the good data, all the results I wanted to view, aggregate, and slice and dice, were still in XML.
How to stop extended events in SQL Server?
There’s no reason to add extra load to SQL Server when you aren’t watching. Make sure to stop and remove your Extended Events session: /* Stop the Extended Events session */ ALTER EVENT SESSION [query hash] ON SERVER STATE = STOP; /* Remove the session from the server.
How to grab a query in extended events?
I set up an Extended Events session to grab a particular query. Create a crappy stored procedure. Use your imagination. Run the stored procedure a lot. Grab the query_hash for that stored procedure. The easiest way I’ve found to do this is to use our plan cache query to identify it. My query_hash is 0x2B42702322C10821.
How is event data represented in SQL Server?
Now we have a new table, #t, which has a single column, event_data , which represents each individual event in XML format. Note that the ring buffer may not maintain as much history as event files, so you won’t necessarily see the same amount of data if you use these two methods on the same system.

The event_file target writes event session output from buffer to a disk file: You specify the filename= parameter on the ADD TARGET clause. .xel must be the extension of the file. The file name you choose is used by the system as a prefix to which a date-time based long integer is appended, followed by the .xel extension.
When was extended events ( xe ) released in SQL Server?
When Extended Events (XE) were released with SQL Server 2008, I was excited – something new to learn! I read Microsoft articles about them, read blog posts about them, and tried to use them. At that time, there was no GUI for XE.
What does’1’mean in extended events in SQL?
The [1] denotes a singleton – it means take the first element (in some cases you may have multiple values represented at a specific node, but for everything here there is only one value). So expanding on that, we can go back to our original query against #t and enhance it.
