mysql如何统计前一天记录?时间存储模式是:time()的
CREATE TABLE `bean` (
`usedate` varchar(12) default NULL,


统计bean数据库 日期字段为:usedate

这样写:
select * from bean where date(usedate) = date_sub(curdate(),interval 1 day);

但出错,提示为:
Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in


可能上面的mysql语句只能统计出Y-m-d hh:mm这样存储格式的时间,如果时间存储是time()的如1340508737,请问如果统计出前一天的记录?!
谢谢!


改成这样也不行:
select * from bean where to_char(usedate,'yyyy-mm-dd') = date_sub(curdate(),interval 1 day);


------解决方案--------------------

SQL code
SELECT * FROM `bean` WHERE FROM_UNIXTIME(`usedate`, '%Y-%m-%d') = DATE_SUB(CURDATE(), INTERVAL 1 DAY) <div class="clear">
                 
              
              
        
            </div>
