我通过

调用存储过程

{ call BPM_CLMBR_RPT_PROC(6,str_to_date('2015-10-01','%Y-%m-%d'),str_to_date('2015-12-31','%Y-%m-%d')); }

查询返回所有记录而不考虑日期约束。但是当在代码中传递硬编码值时

{
RESPONSEDATE BETWEEN  date_format(STR_TO_DATE('11/1/2015', '%m/%d/%Y'),'%Y-%m-%d') AND  date_format(STR_TO_DATE('12/13/2015', '%m/%d/%Y'),'%Y-%m-%d')
}

然后预期结果即将到来。

日期格式在mysql过程中不起作用
