尝试：

SELECT 
  rh.user_name, 
  rh.report_name, 
  rh.report_run_date

FROM 
  report_history rh

  INNER JOIN 
  (
     SELECT 
       max(report_run_date) as maxdate, 
       report_name
     FROM 
       report_history
     GROUP BY 
       report_name

  ) maxresults
  ON rh.report_name = maxresults.report_name
  AND rh.report_run_date= maxresults.maxdate;
