sql="SELECT distinct dateandtime FROM ctarticle WHERE dateandtime between ((#"&date&"#+(Weekday("&date&")"&norp&"7))-6) and (#"&date&"#"&norp&"7)+Weekday("&date&")"
13.5 查询一天, 所隶属星期所有天数的数据
SELECT *
FROM ctdate_by_query_date
WHERE dateandtime between ((#2006-5-15#+Weekday(2006-5-15))-6) and #2006-5-15#+Weekday(2006-5-15)
13.4 查询一个时间段
