Oracle最新日期问题

Question

我试图在以下选择语句中找到最大值（日期）并收到错误...有人可以帮忙吗？

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

Answer 1

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

Answer 2

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;
