In reply to Scott W.

For Azure SQL Database v12 you can grab the deadlock events using the following query:

WITH CTE AS (
SELECT CAST(event_data AS XML) AS [target_data_XML]
FROM sys.fn_xe_telemetry_blob_target_read_file(‘dl’, null, null, null)
)
SELECT target_data_XML.value(‘(/event/@timestamp)[1]’, ‘DateTime2’) AS Timestamp,
target_data_XML.query(‘/event/data[@name=”xml_report”]/value/deadlock’) AS deadlock_xml,
target_data_XML.query(‘/event/data[@name=”database_name”]/value’).value(‘(/value)[1]’, ‘nvarchar(100)’) AS db_name
FROM CTE

Could do with an update for v12 as additional_data is always null

great addition, however you have a little typo there – it is xdl instead of rdl
