13.5.1 列出某一天, 上一星期的数据
SELECT distinct dateandtime
FROM ctdate_by_query_date
WHERE dateandtime between ((#2006-5-15#+(Weekday(2006-5-15)-7))-6) and (#2006-5-15#-7)+Weekday(2006-5-15)
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
SELECT *
FROM ctdate_by_query_date
WHERE dateandtime between #2006-5-1# and #2006-5-30#

13.3.2 列出不同年份的年份, 并且不要相同
select distinct year(dateandtime) from ctarticle
结果如:
Expr1000
2000
2003
2004
2005
2006

13.3.1 列出某一天, 上一年的第一条记录
SELECT top 1 dateandtime FROM ctarticle where year(dateandtime)=(2006)-1
sql="SELECT top 1 dateandtime FROM ctarticle where year(dateandtime)=(year(#"&date&"#))"&norp

13.3 列出某一年的数据
sql="select * from ctdate_by_query_date where year(dateandtime)="&year(rqqdt_)&" order by dateandtime desc"

13.2.1 查找上一月中的第一条记录
SELECT top 1 dateandtime FROM ctarticle where year(dateandtime)=year(#2006-5-28#) and month(dateandtime)=month(#2006-5-28#)-1

sql="select * from ctdate_by_query_date where year(dateandtime)="&year(rqqdt_)&" and month(dateandtime)="&month(rqqdt_)&" order by dateandtime desc"
