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&")"

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)

查询一个时间段

SELECT *
FROM ctdate_by_query_date
WHERE dateandtime between #2006-5-1# and #2006-5-30#

列出不同年份的年份, 并且不要相同

select distinct year(dateandtime) from ctarticle

2005
2006

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

列出某一年的数据

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

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

列出某一月的数据

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

sql="select * from ctdate_by_query_date where dateandtime=#"&rqqdt_&"# order by a.articleid desc"
