求SQL语句。
create table #A(idno varchar(6),B varchar(1),icdate varchar(10),ictime varchar(8))
insert #A
select '000008 ',T, '2007/9/26 ', '01:00:00 ' union all
select '000008 ',T, '2007/9/26 ', '07:00:00 ' union all select '000008 ',T, '2007/9/26 ', '12:30:00 ' union all
select '000008 ',T, '2007/9/26 ', '13:30:00 ' union all
select '000008 ',T, '2007/9/26 ', '17:00:00 ' union all
select '000008 ',T, '2007/9/27 ', '00:30:00 ' union all
select '000011 ',F, '2007/9/26 ', '13:00:00 ' union all
select '000011 ',F, '2007/9/26 ', '19:00:00 ' union all
select '000011 ',F, '2007/9/26 ', '23:00:00 ' union all
select '000011 ',F, '2007/9/27 ', '01:00:00 ' union all
select '000011 ',F, '2007/9/27 ', '07:00:00 ' union all
select '000011 ',F, '2007/9/27 ', '11:30:00 ' union all
select '000008 ',T, '2007/9/27 ', '07:30:00 ' union all
select '000008 ',T, '2007/9/27 ', '10:10:00 ' union all
select '000008 ',T, '2007/9/27 ', '12:30:00 ' union all
select '000011 ',F, '2007/9/27 ', '07:30:00 ' union all
select '000011 ',F, '2007/9/27 ', '10:10:00 ' union all
select '000011 ',F, '2007/9/27 ', '12:10:00 ' union all
要得到结果，B 字段的值是确定的。 他决定了 时间的处理方式。
设X为日期 T白班 (X的1:00(包含1:00)到X+1的00:30:00(包含X+1的00:30:00)) 跨度约23个半小时
设X为日期 F晚班 (X的13:00(包含13:00)到X+1的12:30:00(包含X+1的12:30:00)) 跨度约23个半小时
odno icdate T1 T2 T3 T4 T5 T6 T7 T8 八个固定时间字段
000008 2007/9/26 01:00:00 07:00:00 12:30:00 13:30:00 17:00:00 00:30:00 NULL NULL
000011 2007/9/26 13:00:00 19:00:00 23:00:00 01:00:00 07:00:00 07:30:00 10:10:00 11:30:00
000008 2007/9/27 07:30:00 10:10:00 12:30:00 NULL NULL NULL NULL NULL
在结果中忽略 多于的就是 超出8个的时间 如结果第二条记录中就有
select '000011 ',F, '2007/9/27 ', '12:10:00 ' union all 被忽略了。
希望大家一起帮帮忙。
