Trigger on the table

FOR INSERT,UPDATE
AS  
begin   

    DECLARE @ExecStr varchar(50), @Qry nvarchar(255)

    CREATE TABLE #inputbuffer 
    (
      EventType nvarchar(30), 
      Parameters int, 
      EventInfo nvarchar(255)
    )

    SET @ExecStr = 'DBCC INPUTBUFFER(' + STR(@@SPID) + ')'

    INSERT INTO #inputbuffer 
    EXEC (@ExecStr)

    SET @Qry = (SELECT EventInfo FROM #inputbuffer)


    INSERT INTO tblDoneWhoMonitor(CallId,DoneWho,Operation,Query)
    SELECT  case
            when inserted.CallId is null then deleted.CallId
            when deleted.CallId is null then inserted.CallId
            else deleted.CallId end,
            case
            when inserted.CallId is null then deleted.DoneWho
            when deleted.CallId is null then inserted.DoneWho
            else deleted.DoneWho end, 
            case
            when inserted.CallId is null then 'DELETE'
            when deleted.CallId is null then 'INSERT'
            else  'UPDATE' end,
            @Qry
    FROM inserted
    FULL OUTER JOIN deleted
    ON inserted.CallId = deleted.CallId
end

The EventInfo column is too small. Change it to max. You will need to change the @Qry to nvarchar(max) as well.

CREATE TABLE #inputbuffer 
    (
      EventType nvarchar(30), 
      Parameters int, 
      EventInfo nvarchar(max)
    )

@Qry nvarchar(max)

And in turn you will need to modify the table definition for tblDoneWhoMonitor to accept the Query as well.
