Sqlserver与Access 时间范围查询

一、sqlserver

第一步：首先要确定数据库的字段是否是datetime日期时间型。

第二步：如果不是datetime类型，必须将其转换为datetime日期时间型。如：CONVERT(DATETIME,'2013-04-01 00:00:00',102)

第三步：sql语句写法

--方法1：字段不是日期时间型，转换成日期时间型
SELECT id AS id,rq AS 日期,yhxm AS 用户名,xq,yhdz AS 地址,yhdh AS 电话,slr AS 受理人,lr AS 内容,lb AS 类别,zt,yqsj  AS 要求时间,hdrq 
      AS 回单时间
FROM dbo.hjzx
WHERE (rq >= CONVERT(DATETIME,102)) AND 
      (rq <= CONVERT(DATETIME,'2013-06-30 00:00:00',102)) and (CONVERT(DATETIME,yqsj,102)< hdrq)


--方法二：
select * from hjzx where id<>''  and CONVERT(varchar(100),xdsj,23)>='2013-07-03'  and CONVERT(varchar(100),23)<='2013-07-04'  order by id desc

--方法三：
select * from lcmxb where lb_gc >'0' and convert(char,shtime,112)>='20110718' and convert(char,112)<='20110720'

 

 

 

二、Access

select * from lcmxb where lb_gc >'0' and format(shtime,'YYYYMMDD')>='20110718' and format(shtime,'YYYYMMDD')<='20110720'
