| 请问一下，在查询报表的日期范围时候用between and就报错；用>= 和<= 就成功这是为什么？ ${if(len(dbill_date1)==0 && len(dbill_date2)==0 ,"","and dbill_date between '"+ dbill_date1 + " and " + dbill_date2 +"'")}  ${if(len(dbill_date1)==0,"","and dbill_date >='"+ dbill_date1 +"'")} ${if(len(dbill_date2)==0,"","and dbill_date <='"+ dbill_date2 +"'")}  |
