由于mysql中的Clause命令，我的查询将无法正常工作

Question

I am writing query for displaying data and added order by clause in that query. My query Is

SELECT * FROM `coupons` 
WHERE `status` = 'A' &&  `type` = '2'    
&&  `time` > CURDATE() && `start_date` <= CURDATE()
order by `stocks` asc 

In above query it get sorted by 'stocks' but in some cases stocks is zero , that case i want show this row at the last. what should i do please help . thanks in advance.

Answer 1

order by CASE WHEN `stocks` = 0 THEN 1 ELSE 0 END asc , `stocks` asc 

Answer 2

SELECT *, (if(`stocks` != 0,`stocks`,"")) as newstocks FROM `coupons` 
WHERE `status` = 'A' &&  `type` = '2'    
&&  `time` > CURDATE() && `start_date` <= CURDATE()
order by newstocks asc 

Use above code.

Answer 3

By default it is asc so you don't have to mention it. Try the below one

SELECT * FROM coupons WHERE status = 'A' && type = '2' && time > CURDATE() && start_date <= CURDATE() order by case stocks != 0 then stocks end, stocks

It will first list the items with stocks is nozero and then list the rows with stocks=zero
