现有表 Term
结构如下
time1 time2 idterm
2009-2-15 2009-6-30 11
2009-9-10 2010-1-15 12
如果输入 2009-4-25 则应该取出idterm 11
如果输入 2009-12-5 则应该取出idterm 12
这个SQL该怎么写？
分少请见谅
SQL code:
select idterm from tb
where time1<=输入日期 and time2>=输入日期
SQL code:
declare @time datetime
set @time ='2009-4-25'
select top 1 * from term where time1<=@time and time2 >=@time
SQL code:
declare @time1 datetime,@time2 datetime
set @time1=..
set @time2=..
select idterm from tb where time between @time1 and @time2
case...when....then..
select idterm from tb
where time1 <=time2 and time2>=time1
