复制代码 代码如下:
13.5.1列出某一天,上一星期的数据
SELECTdistinctdateandtime
FROMctdate_by_query_date
WHEREdateandtimebetween((#2006-5-15#+(Weekday(2006-5-15)-7))-6)and(#2006-5-15#-7)+Weekday(2006-5-15)
sql="SELECTdistinctdateandtimeFROMctarticleWHEREdateandtimebetween((#"&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*
FROMctdate_by_query_date
WHEREdateandtimebetween((#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*
FROMctdate_by_query_date
WHEREdateandtimebetween#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
selectdistinctyear(dateandtime)fromctarticle
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
SELECTtop1dateandtimeFROMctarticlewhereyear(dateandtime)=(2006)-1
sql="SELECTtop1dateandtimeFROMctarticlewhereyear(dateandtime)=(year(#"&date&"#))"&norp

13.3列出某一年的数据
sql="select*fromctdate_by_query_datewhereyear(dateandtime)="&year(rqqdt_)&"orderbydateandtimedesc"

13.2.1查找上一月中的第一条记录
SELECTtop1dateandtimeFROMctarticlewhereyear(dateandtime)=year(#2006-5-28#)andmonth(dateandtime)=month(#2006-5-28#)-1

13.2列出某一月的数据
sql="select*fromctdate_by_query_datewhereyear(dateandtime)="&year(rqqdt_)&"andmonth(dateandtime)="&month(rqqdt_)&"orderbydateandtimedesc"

13.1列出某一日的数据
sql="select*fromctdate_by_query_datewheredateandtime=#"&rqqdt_&"#orderbya.articleiddesc"

13.时间日期
例一:列出当天的数据
sql="select*fromctdate_by_query_datewheredateandtime=date()orderbya.articleiddesc"
