Read ALL SQL deadlock information from Extended Events Log

How to read single deadlock information from extend event log

Read SQL deadlock information from Extended Events Log

So if we want to read all deadlock information which log into extend event,

how I doing ?

1. Run the below query in ssms to retrieve deadlock information from extend event.

Remember to change the folder name based on sqlversion

 "FROM sys.fn_xe_file_target_read_file('D:\MSSQL11.MSSQLSERVER\MSSQL"

 2. Copy the result into notepad and save

3. Open the notepad from excel with delimited "|"

4. All deadlock information will show in excel worksheet

create table #tempdeadlock
(rownumber int,
 Code varchar(max),
 Code2 varchar(max),
 Code3 varchar(max),
 Code4 varchar(max),
  Code5 varchar(max),

   DeadlockObject varchar(200),
