Mysql小于或等于+不等于0

Question

我有这个Mysql代码

SELECT * FROM `members` WHERE (bandwidth<='$calc_total_bandwidth' AND username!='$usern') ORDER BY RAND() LIMIT 1

带宽＆lt; ='$ calc_total_bandwidth'=小于等于

但我仍然坚持我也能做到这一点所以它“不等于0”？

Answer 1

WHERE子句中只有AND一个!=0吗？

SELECT * FROM `members`
WHERE `bandwidth` != 0
AND `bandwidth` <= '$calc_total_bandwidth' 
AND `username` != '$usern'
ORDER BY RAND()
LIMIT 1
