mysql 移动结果集底部的行

Question

我正在尝试移动结果集底部值小于当前日期的行。我有这个查询

SELECT 
r_id AS Id,
f_title AS Title,
f_desc AS Description,
f_upload_file AS File,
ABS(DAYOFYEAR(f_valid_date)- DAYOFYEAR(CURDATE())) AS Deadline,
f_added_on as 'Added On'
FROM t_documents
WHERE 
f_rec_status= TRUE
ORDER BY Deadline ASC

它给出了这个结果:

我们将不胜感激。

Answer 1

试试这个，

ORDER BY (CASE WHEN Deadline IS NULL
               THEN 1 ELSE 0 END) ASC, Deadline ASC
