Question

Answer 1

This code will display the error log which contains the query that creates the deadlock. IF OBJECT_ID('tempdb.dbo.ErrorLog') IS Not Null BEGIN DROP TABLE tempdb.dbo.ErrorLog END

 CREATE TABLE tempdb.dbo.ErrorLog 
 (Id int IDENTITY (1, 1) NOT NULL, 
  logdate DATETIME, procInfo VARCHAR(10), 
  ERRORLOG VARCHAR(MAX))

  -- insert the actual data from the Error log into our newly created table.

 INSERT INTO tempdb.dbo.ErrorLog
 EXEC master.dbo.sp_readerrorlog


declare @sql nvarchar(max)
set @sql='select logdate, procInfo, ERRORLOG from tempdb.dbo.ErrorLog 
where Id >= (select top 1 id  from tempdb.dbo.ErrorLog WHERE ERRORLOG Like 
''%deadlock-list%'' order by id desc)'
select @SQL
