Oracle最大日期问题

Question

我正试图在下面的select语句中找到最大值（日期）并获取错误......有人可以帮助吗？

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;
