Oracle最大日期问题

我试图在下面的select语句中找到maxdate，但出现了错误…有人能帮忙吗

SELECT MAX(STMT_DATE) < STMT_CLOSE_DATE as "lastdate"
  FROM STMT_FACT;

该怎么办？

SELECT MAX(STMT_DATE) as "lastdate"
FROM STMT_FACT
WHERE STMT_DATE < STMT_CLOSE_DATE

To get only Max date:-
  SELECT MAX(STMT_DATE) as "lastdate" FROM STMT_FACT WHERE STMT_DATE < STMT_CLOSE_DATE

To get complete row which contains latest date:-
  SELECT STMT_DATE as "lastdate", [Rest of the columns] FROM (SELECT STMT_DATE FROM 
  STMT_FACT WHERE STMT_DATE < STMT_CLOSE_DATE ORDER BY STMT_DATE DESC) WHERE rownum=1;
