Sessão de eventos estendidos do SQL para detecção de deadlock

Existe uma maneira de aumentar o tamanho do <inputbuf>elemento no XML do deadlock capturado pela sessão de eventos estendidos do deadlock?

Queremos ver a consulta completa para ajudar a identificar o problema no código do aplicativo.

Parece estar limitado a 1024 caracteres +/-. Pode ser aumentado?

Veja abaixo o exemplo de XML. Você pode ver que o texto da consulta no <inputbuf>elemento é cortado no meio da lista de seleção:

Você tem um sqlhandlepara cada quadro para poder obter a consulta completa usando a sys.dm_exec_sql_textfunção:

SELECT text
FROM sys.dm_exec_sql_text(sql_handle)

sys.dm_exec_sql_text

Por exemplo, obtendo o texto de algumas instruções de sys.dm_exec_query_stats(stmtstart, stmtend, sqlhandle em vez de statement_start_offset, statement_end_offset, sql_handle no relatório XML)

SELECT TOP (100)
    CASE   
        WHEN s.[statement_start_offset] > 0 THEN  
            --The start of the active command is not at the beginning of the full command text 
            CASE s.[statement_end_offset]  
               WHEN -1 THEN  
                  --The end of the full command is also the end of the active statement 
                  SUBSTRING(t.TEXT, (s.[statement_start_offset]/2) + 1, 2147483647) 
               ELSE   
                  --The end of the active statement is not at the end of the full command 
                  SUBSTRING(t.TEXT, (s.[statement_start_offset]/2) + 1, (s.[statement_end_offset] - s.[statement_start_offset])/2+1)   
            END  
        ELSE  
            --1st part of full command is running 
            CASE s.[statement_end_offset]  
               WHEN -1 THEN  
                  --The end of the full command is also the end of the active statement 
                  RTRIM(LTRIM(t.[text]))  
               ELSE  
                  --The end of the active statement is not at the end of the full command 
                  LEFT(t.TEXT, (s.[statement_end_offset]/2) +1)  
            END  
        END AS [executing statement]
FROM sys.dm_exec_query_stats s 
    CROSS APPLY sys.dm_exec_sql_text(s.[sql_handle]) t

UPD

Graças ao comentário razoável de @ JohnEisbrener, devo observar que as informações dos DMVs serão reais até que o cache da consulta seja limpo. Portanto, se você espera usar essas informações após a limpeza do cache (por exemplo, após a reinicialização do servidor), salve esses dados em alguma tabela permanente imediatamente após a ocorrência do evento.
